How to tell if your smartphone’s battery is dying

If you are reading this article, it’s probably because your smartphone is acting up or you’re worried that its battery is nearing the end of its life. And you have good reason to worry about the longevity of smartphone batteries. No matter how well you treat your mobile device, eventually, the battery will lose its capacity to hold a charge and your smartphone or tablet will need servicing. Are you curious about how much an Android smartphone battery lasts? Or maybe you want to know the signs that your iPhone battery is dying?

Then, read on:Battery wear is unavoidableSmartphone batteries have come a long way since the early days of mobile devices. Modern smartphones use Lithium-Ion batteries, which have great energy density (meaning they can store a great deal more energy than older batteries, in the same volume), very weigh little, and can be charged relatively fast. But with each charging and discharging, all batteries developed so far lose some of their ability to hold a charge. Energy is stored by transforming electrical current into chemical energy, and over time, materials inside the battery degrade because of that process. If you want more details about why batteries wear over time, here’s an article that explains it in more detail.


So, how much does a smartphone battery actually last?

Well, current technology allows for around 4-500 charging-discharging cycles (from 100% to around 20% and then up again to 100%) before a battery starts losing capacity at an accelerated rate.


If you calculate one full cycle per day, this equates to about two years of usage. After these 4-500 cycles, the battery capacity (which is measured in mili-ampere hour, or mAh) is going to be less than 80% of its original value. Not long after that, the battery will start deteriorating rapidly. If your battery is already acting up, or if you’ve had your smartphone for longer than two years, you should watch out for these signs:
How to tell whether your smartphone’s battery is dying

You did your best to protect the battery (or maybe you didn’t), but now the battery starts acting up. How do you know if it’s dying? Both on Android devices and on iPhones and iPads, battery wear doesn’t manifest itself suddenly.

Even a healthy battery will decrease in capacity over time, but it will do so very slowly. Once it gets to around 80% of the original capacity, though, the effects are much more visible and may interfere with the normal use of the smartphone. Here are eight signs that your battery should be replaced:
1. The battery percentage drops immediately after removing the chargerNormally, the battery should stay at 100% for at least a few minutes after fully charging it. Let it reach 100%, remove the charger and watch the battery percentage. If it drops a few percent immediately, without using it, you should start thinking about replacing the battery.


2. Charging takes longer, especially the last few percentMonitor charging times. If your smartphone takes significantly longer to charge (let’s say an hour and a half compared to an hour when it was new), using the same charger as before, there’s definitely a problem. Furthermore, if charging the last few percent takes forever, it’s a good idea to start looking for a replacement battery (or a service).
Watch out for extremely long charging times3. The smartphone shuts down at a higher battery percentage than normalA smartphone with a good battery should go as low as one or even zero percent until it shuts down. Most modern smartphones warn you 30 seconds before they initiate auto-shutdown so that you have time to save your work. However, if you see it shutting down at higher percentages (like 10-15% or even more), the battery should be replaced.


4.Battery lasts substantially lessAs we mentioned before, once the battery goes beyond a certain number of charge-discharge cycles, its capacity starts declining rapidly. If your smartphone lasts much less than when you bought it, this could be a sign that your smartphone battery is nearing the end of its life. Beware, though, as the battery can also be drained faster due to increased usage or applications consuming battery in the background. To make sure it’s the battery, verify that your usage times haven’t changed and you haven’t installed new applications that could potentially drain the battery faster.


Nothing worse than having your smartphone die on you in the middle of an outdoors activity5. Your smartphone or tablet shuts down when using power-intensive appsIf you suspect your battery is dying, do the following experiment: with the battery as low as 20%, try using the camera to record a video. If the smartphone shuts down quickly or before reaching 1 or 2%, the battery is on its way out. The reason you should try using the camera is simple: it’s one of the (if not the) most power-hungry systems on a smartphone. If the battery is dying, it can’t provide sufficient current to the camera, and the device shuts down.

What can I do if my smartphone’s battery is dying?

Okay, so now you’re positive that your battery has only a few charges left before it finally loses the ability to turn on the phone. What should you do next? Unfortunately, for most modern smartphones and especially Apple devices, the only solution is to take it to a repair shop. Battery replacement is a routine operation and shouldn’t affect the functionality of your device. It usually takes a technician 10-60 minutes to replace the Apple battery, and new parts are available for just about any modern smartphone.

You may wonder: should I attempt to replace the battery myself?

The answer depends on how handy you are with a screwdriver. On almost all modern smartphones, you need to go past glued cases, lots of screws, and even a few connectors to get to the battery. And even then, the battery itself is glued to the chassis, so removing it takes patience. If you want to try replacing it yourself, first look at a tutorial or two on YouTube, there should be plenty available. We recommend iFixit’s YouTube channel for detailed repairs on various mobile devices. Next, make sure you have all the tools and the replacement parts. Take your time to understand the procedure and perform it.

And finally, start with low expectations 
Don’t hesitate to replace the battery, it doesn’t damage the device if it’s done properlyNOTE: If you replace the battery yourself, make sure you dispose of it properly. First, insulate the battery terminals or wires to prevent short circuit, then take the battery to a local battery collection facility. Do not throw it away in the bin. Lithium batteries are extremely flammable if subjected to mechanical damage, not to mention the gasses released are poisonous.

Do you usually replace the battery or the whole smartphone?

We hope our guide helps you diagnose the issues you have with your smartphone. Before leaving this page, we’re curious to know: how many times did you replace the battery on your devices? Did you do it yourself or did you go to a repair shop? Or maybe you just never bothered to change theiphone battery and just replaced the device? Drop a comment below and let us know!

The iPhone gets its first Apple-made battery case. Would you buy it?

Apple has released a battery case that fits both the iPhone 6 and iPhone 6s. The move is unprecedented for Apple, which has been sticking firmly to the thin design for its smartphones. Producing a battery case means that they admit a legitimate need to supplement the capacity of their smartphone’s original battery. Let’s have a closer look at the battery case and see what Apple is offering to their customers:
The iPhone 6s Smart BatteryCase breaks Apple thin designApple has shunned until now the calls for bigger batteries, sticking to its guns on the slick design of its iPhone. In fact, every new iPhone has been thinner than its predecessor which showed marvelous engineering put to work for impressive looks.


With this background, it is surprising that Apple made such a fork in the road and is pushing a product that will make its flagship smartphone thicker.
First of all the battery case is meant for iPhone 6 and iPhone 6s. The name of the product in the online Apple shop indicates iPhone 6s (iPhone 6s Smart Battery Case), but don’t let this fool you. A few lines below in the description, Apple clarifies that the product is fully supported for iPhone 6 too.


A battery case that fits your iPhone like a gloveThere are plenty of battery cases for iPhones, made by third-party vendors. Apple’s version features only a 1,877 mAh charge, which is not that impressive given that you can find battery cases like this one from Diskin that offer 3,050 mAh. What Apple offers that sets this battery case apart is a very good integration with iPhone’s hardware and software:


The charging of the case is done through a Lightning connector which means you don’t need a separate charger for the case. Many battery cases from other vendors charge though a micro USB connector. Another plus is that the smartphone and the case both charge when the Lightning connector is fitted to the case. One minus is that the battery case starts charging your iPhone immediately as you connect it, even if the phone is fully charged.

The case has a mic and a speaker, as it covers the original iPhone ones. An added benefit is the speaker is front facing which makes for better audio.

The software becomes aware of the battery case when connected and it shows the phone and the case batteries separately, how much each one has left and the charging sign when connected to the charger.

The materials are superior quality including a microfiber lining that protects the iPhone. The battery itself though sticks out in the case and creates a bulge on the back of the phone. You have to wonder whether a thicker design of the iPhone 6 or 6s on its entire surface would not have been the better option.You have to check the headphones connection. The case provides a canal that allows connecting directly to the iPhone. The canal may not be large enough for all headphones connectors.The case of extra iPhone. battery life


Apple stays away from specifying the milliamperes hour for the batteries of its iPhones. This may not be entirely unwarranted because the flat comparison of the capacities of batteries between smartphones can be deceiving. To be fair Apple has produced amazing devices that manage to do more with even less battery capacity. Case in point is iPhone 6 which has a smaller battery than iPhone 5 yet manages to last longer in use. iPhone 6s shrinks the battery capacity even more.
Having said that, the listing of hours of use, which is what Apple does in the specs for iPhone 6 and 6s, is equally deceiving. The performance listed for each type of use (like Internet, talk time, video playback) does not reflect real life use.


If you decide now on buying an iPhone 6 or 6s, the real life use tests put the usage time of a full battery charge at around 7 and a half hours. Of course this is an average and actual use can vary significantly by individual case. Video playback can last 11 hours while playing games can run down the battery in 3 and a half hours. If you own one, you already know best how much you can rely on the battery of your iPhone.


The battery case adds 80% to the usage time. The case has a bigger battery than the iPhone, but the transfer of energy is never perfect from a battery case. It makes sense to use it if you are a heavy user and cannot make it to the evening with one full battery charge or if you want to have the peace of mind that a backup is available when you skip the nightly charge.

Which iPhone battery case do you use?

I’m sure that many iPhone owners already have a battery case. If you do too, let us know which case you are using. Is it better than the one made by Apple? And what do you think of Apple’s batterycase? Would you buy it?

Galaxy S23 and S23 Plus camera is similar to the S22

While battery life improved, the Galaxy S23 and S23 Plus have the same charging speeds as last year. The Galaxy S23 supports 25-watt fast-charging and 45-watt fast-charging for the Galaxy S23 Plus. But in practice, those charging speeds didn’t feel that different. The Galaxy S23 went from 47% to 86% after 30 minutes, while the Galaxy S23 Plus went from 59% to 94%. 


While charging speed isn’t a deal-breaker when buying a new phone, it would have been nice to see Samsung push forward in this area. That’s especially true considering rivals like Xiaomi and OnePlus continue to shorten the time it takes to replenish their respective 

Galaxy  Battery phones’ batteries. Galaxy S23 and S23 Plus’ new processor is fast
The cS23 and S23 Plus feel snappy and fast in everyday use, as phones in their price range should. Playing games with the graphics and frame rate at the highest settings felt smooth, and apps launched instantly. All three new phones have an adaptive refresh rate that reaches up to 120Hz for smoother scrolling and animations, which also contributes to the devices’ peppiness. 


The one area where the new Qualcomm Snapdragon 8 Gen 2 processor seems to make a difference in everyday use is exporting video. The Galaxy S23 and S23 Plus both exported a 30-second 4K video to 1080p faster than the Galaxy S22 Ultra and Pixel 7 Pro The iPhone 14, however, was the fastest of the bunch. The Galaxy S23 lineup runs on a special customized version of Qualcomm’s latest mobile chip that’s been optimized for these phones, meaning it’s different from the version inside the OnePlus 11.


Video export test
Benchmarks meant to test general computing (Geekbench 5) and how a processor handles high performance in short bursts (3DMark) told a similar story. The Galaxy S23 and S23 Plus performed well compared to the Galaxy S22 and Pixel 7 Pro, and even outperformed the iPhone 14 on most tests. The OnePlus 11 was their closest competitor, which isn’t surprising considering it has a similar processor. But the Galaxy S23 and S23 Plus did outpace the OnePlus 11 in the test meant to evaluate a processor’s single-core performance , which makes sense considering Samsung overclocked one of the CPU cores. 
That said, real-world usage matters more than benchmarks. Other than the faster video export speeds, I didn’t experience anything on the Galaxy S23 lineup that felt unusually fast compared to most other phones in the same price range.


Galaxy S23 and S23 Plus camera is similar to the S22The Galaxy S23 and S23 Plus each have a triple rear camera that consists of a 50-megapixel main camera, 12-megapixel ultra wide and a 10-megapixel telephoto. Thanks to a technique called pixel binning, you can choose to shoot photos at the full 50-megapixel resolution or 12 megapixels depending on the scenario.

The 12-megapixel option, for example, is usually better for poorly lit circumstances since it groups multiple pixels together to serve as a larger pixel for gathering more light. Samsung also integrates the controls from its Expert Raw app right into the main camera, making it more convenient for those who want easy access to the full, uncompressed version of an image. 
This camera system is largely the same as the one on the S22, although Samsung has made some processing improvements, particularly when it comes to low light photography. That’s the biggest difference I noticed during my time testing the new Samsung phones against the Galaxy  S22. 


Check out the photos of my husband in a dim restaurant below. His face is brighter and his beard is more detailed.

Still, I preferred the iPhone 14’s and Pixel 7 Pro’s images, mostly because they captured more accurate skin tones. The Galaxy S23’s photo is brighter and more detailed than the Pixel 7 Pro’s, but it also makes his face look a little washed out.

The Galaxy S23 performs well in dim conditions overall, which isn’t surprising considering low-light photography has been a big area of ​​​​​​focus for Samsung  Battery  in recent years. Even though the iPhone 14 and Pixel 7 Pro performed better in the examples above, the S23 easily challenges Apple and Google in other low-light photography scenarios, like taking photos of pets and still objects.
In the photos of a book stack below, for example, the Galaxy S23 did a great job at retaining detail and color. The iPhone 14’s photo isn’t as colorful and has some noise compared to Samsung’s, although the Pixel 7 Pro’s image was a close competitor.

Otherwise, there isn’t anything that feels new or surprising about the Galaxy S23’s camera. While the Galaxy S23 and S23 Plus can both capture crisp and clear images, there were instances in which colors either looked exaggerated or blown out compared to the same photos taken on the iPhone 14 and Pixel 7.
You can see an example of the exaggeration in this photo of my husband below. The shade of blue in his denim jacket is brighter than it looked in real life, while the iPhone 14 and Pixel 7 Pro’s photos look more natural.

But a s I said in my review of the S23 Ultra, this isn’t always a bad thing. It can make certain photos pop and look more attractive overall, as is the case with the photo below. The pink flowers look more colorful and vibrant in the S23’s photo compared to the rest.

Samsung also upgraded the Galaxy S23’s selfie camera with a 12-megapixel sensor compared to the S22’s 10-megapixel front camera. However, I didn’t notice much of a difference under normal circumstances. 

But Samsung’s phones  Battery easily took better selfies in low light compared to the iPhone 14 and Pixel 7 Pro. The photos from Google and Apple’s phones are both noisier and grainier than Samsung’s, which I noticed when comparing the photos on a large monitor. The Galaxy S23’s selfie is also a bit clearer than the S22’s, but the difference isn’t as dramatic.   

The Galaxy S23 and S23 Plus have a 3x optical zoom and 30x digital zoom, just like the S22 and S22 Plus. You’ll need to splurge on the $1,200 Galaxy S23 Ultra to get the 10x optical zoom and 100x digital zoom. 
But the S23 and S23 Plus still have more to offer than the $799 iPhone 14, which has a 1x optical zoom and a 5x digital zoom. 

Samsung is usually the king of zoom, but in this scenario Google takes the cake. The Pixel 7 Pro has a 5x optical zoom and a 30x digital zoom that looks far crisper than Samsung’s, as shown below.

As far as video recording is concerned, the S23 and S23 Plus can record at 8K resolution up to 30 frames per second. When recording video at the highest supported resolution and frame rate for each phone (4K at 60 frames per second for the iPhone 14 and Pixel 7 Pro), I noticed the Galaxy S23’s footage had more accurate color tones compared to the Pixel 7 Pro. The iPhone’s video, however, looked a bit crisper.
I also noticed that video stabilization improved slightly on the Galaxy S23 compared to the Galaxy S22, enabling it to better compete with Apple’s Action Mode.


The Galaxy S23’s camera isn’t a leap forward, but it’ll feel significant to those upgrading from a phone that’s several years old.

Samsung’s Galaxy S23 FE Arrives With Bigger Battery and Larger Screen

Samsung’s cheaper flagship phone makes noticeable cuts from the Galaxy S23, but it’s still a speedy phone.
The $600 (£599, AU$999) Samsung Galaxy S23 FE revives the company’s Fan Edition of phones, and it’s selling for a much lower price than the original $800 Galaxy S23. Samsung’s lower-priced flagship, first revealed on Oct. 3 and now available for purchase, keeps many higher-end features like the inclusion of a telephoto lens for the camera and reverse wireless charging. There are noticeable changes, however, that might not affect the phone’s overall appeal, but reveal how Samsung was able to offer the phone for $200 less.


This story is part of Samsung Event, CNET’s collection of news, tips and advice around Samsung’s most popular products.The S23 FE’s release comes after Samsung paused the line in 2022, having released the Galaxy S21 FE early that year, but decided to not release a Galaxy S22 FE. These phones have aimed to provide as much of the flagship phone experience as possible for less money, and in some cases improve by including a bigger battery and screen. While Samsung does offer a lot of Galaxy A phones priced at $450 and lower, Samsung’s FE phones tend to focus on the most noticeable features from its higher-end line while making cuts in areas that could be less noticeable.
Galaxy S23 FE front


In the case of the Galaxy S23 FE, Samsung decided to scale back by using last year’s Qualcomm Snapdragon 8 Gen 1 processor — but that processor is still quite powerful for most tasks and can be found in Motorola’s $1,000 Razr Plus foldable phone. In my initial day of testing the Galaxy S23 FE, the phone zips through tasks like installing apps, toggling through my text message threads and loading up my news feeds. There’s also a noticeable change in the phone’s appearance, with the standard Galaxy S23 using a more glossy aluminum than the aluminum used on the FE.  
Samsung Galaxy S23 FE with Galaxy Watch 6.


The Galaxy S23 FE has a 50-megapixel wide camera and a 12-megapixel ultrawide camera, similar to the Galaxy S23, but its 8-megapixel telephoto camera is a minor step down from the regular S23’s 10-megapixel zoom camera. also uses a 10-megapixel front-facing camera, versus the 12-megapixel one seen on the standard S23.
However, the Galaxy S23 FE does include a slightly bigger battery than the original S23: 4,500 versus 3,900 mAh. The phone is also a little bigger than the Galaxy S23, with the FE including a 6.4-inch display that makes it a hair shorter than the 6.6-inch display on the S23 Plus. The S23 FE’s display can run at a 120Hz refresh rate, but will adapt between that and 60Hz, depending on the phone’s activity, to save Samsung Galaxy battery  .


But aside from those differences, the phone shares many similarities with the Galaxy S23. That includes Android 13, wired charging at a speed of 25 watts, wireless charging along with the ability to wirelessly charge other devices, an in-display fingerprint sensor and 128GB or 256GB storage options. Unlike the cheaper $450 Galaxy A54 5G, the S23 FE does not include expandable storage via microSD.
The phone will be available in six colors at launch, with stores getting mint, purple, cream and graphite. Indigo and tangerine colors will also be available through Samsung’s website.


During an earlier demo I had with the S23 FE, I took a few sample photos at the Samsung 837 showroom in New York. 
While I’ll need more time with the phone to get a better impression, my initial thoughts put the Galaxy S23 FE as less of an alternative for “fans,” but more as an option to consider as a step up from the $499 Pixel 7A and the Galaxy A54. While camera testing will be needed to see how the FE compares to the 7A, the new Samsung phone does have a slightly bigger screen than Google’s phone. The S23 FE also includes a telephoto lens with a 3x optical zoom, which neither the 7A nor the Galaxy A54 include.
The Galaxy S23 FE arrives in the midst of the busy fall phone season, debuting the night before before Google plans to unveil its Pixel 8 line. Samsung is also likely to reveal the Galaxy S24 early next year, only a few months from now.
But the FE does provide a more premium option for someone looking to step up from phones that normally cost between $300 to $500, and it could provide all the essentials at that lower price.


Samsung Galaxy S23 and S23 Plus Review: It’s All About the Battery Life
These new phones fix the Galaxy S22’s biggest problem.
Editors’ note, Nov. 1: With its sleek design, vibrant screen, improved battery life and versatile camera system, Samsung’s Galaxy S23 is a top choice for Android fans in search of a premium smartphone. We originally reviewed the Galaxy S23 at launch in February, but are recognizing it with an Editors’ Choice Award now that we’ve reviewed other more recent smartphone releases from competitors throughout 2023. Our original review, published on Feb. 19, 2023, is as follows.
This story is part of Samsung Event, CNET’s


 collection of news, tips and advice around Samsung’s Smartphone Battery most popular products. Samsung hasn’t been shy about flaunting the cameras on its new phones. It even wrangled endorsements from acclaimed directors Ridley Scott and Na Hong-jin during its Galaxy S23 announcement. However, in a surprising move for Samsung, the camera plays second fiddle to battery and performance upgrades in the new Galaxy S23 and S23 Plus. 


The Galaxy S23 ($800, £849, AU$1,349) and Galaxy S23 Plus ($1,000, £1,049, AU$1,649), which are available today alongside the $1,200 Galaxy S23 Ultra (£1,249, AU$1,949), feel like a half-generation upgrade compared to last year’s Galaxy S22. But unlike the Galaxy S23 Ultra’s cameras, which have noticeable improvements in color tone and dynamic range along with a new 200-megapixel sensor, the Galaxy S23 and S23 Plus’ cameras largely feel the same as last year.Performance is faster, and Galaxy S22 battery life is thankfully a bit longer, which addresses the biggest complaint I had about the Galaxy S22.

Samsung’s One UI 6 Update Gives Galaxy Phones More AI Camera Smarts

Samsung’s new update, based on Android 14, shows how the company will incorporate AI into the cameras of its Galaxy phones.
Samsung’s Galaxy phones will soon get aa bevy of new camera features, some of which are powered by AI, as part of the company’s One UI 6 software.


The update, which is based on Google’s broader Android 14 software, is said to have begun rolling out to certain countries in Europe and will be arriving in the US in the coming weeks. The launch comes as AI is beginning to play a larger role in Samsung Cell Phone Battery as recent announcements from Google and Qualcomm have indicated. 

Samsung appears to be taking a page from Apple and Google when it comes to certain camera-related features in One UI 6. For example, a feature called AI Image Clipping will let Galaxy users cut certain objects out of a photo and turn them into stickers that can be placed on other photos. Apple has a similar feature in its recently launched iOS 17 iPhone update. A GIF within Samsung’s press release also shows the sticker being resized after it’s been pasted onto another image, which is somewhat reminiscent of Google’s Magic Editor tool for the Pixel 8 and Pixel 8 Pro.


Samsung is also building on its Galaxy Battery Enhance-X app, an existing app with extra photo-editing tools, like the ability to sharpen older photos similar to Google’s Photo Unblur. With One UI 6, that app will get new capabilities such as Sky Guide, which uses AI to identify constellations and stars after taking a photo of the night sky. 
You’ll also be able to apply Samsung’s Single Take feature in Enhance-X to videos and images with motion that you’ve already captured. Single Take is a camera mode on Samsung phones that lets you capture multiple images at a time in different styles by tapping the shutter button once. In Enhance-X, it sounds like your phone will be able to extract the best stills and clips from existing images using Single Take. Other features coming to the app include the ability to sharpen blurriness from a smudged camera lens in photos and turn regular videos into slow motion clips by generating extra frames.


A photo of Samsung’s Enhance-X app showing Single Take
Aside from these AI-powered features, the company is hoping to make using the camera more convenient. The update should improve document scanning, and you’ll be able to switch to a higher resolution shooting mode more easily in the camera app. If you have frequent camera modes that you prefer, such as panorama or portrait, you’ll also be able to save them directly to the home screen as widgets. Samsung is also updating the editing tools layout in the camera app and adding undo and redo buttons for toggling between edits.
Samsung’s One UI 6 update is another sign that smartphone Battery makers are seeking new ways to incorporate AI into current and future products. AI has played an important role in smartphones for years when it comes to features like voice recognition, language translation and object recognition in photos But the boom in generative artificial intelligence, or AI that can create content based on prompts, following the success of ChatGPT, has fueled greater interest in AI. 


Qualcomm designed its next-generation Snapdragon 8 Gen 3 smartphone chip around AI use cases and applications. The AI-powered photo-editing features in the Pixel 8 and 8 Pro are the factors biggest that separate them from last year’s Pixel 7 family. And Apple is said to be developing new AI features for iOS 18, according to Bloomberg. Now, we’re getting a sense of how Samsung will incorporate AI into its Galaxy phones with One UI 6. 


Samsung’s new software, launched in beta for the Galaxy S23 in August, and social media posts spotted by 9to5Google and Android Authority suggest the software has launched in parts of Europe. A Samsung spokesperson told CNET it will come to US devices in the coming weeks.

Which Google Pixel Phone Should You Buy?

GOOGLE’S PIXEL PHONES are our favorite Android phones here at WIRED, and they have been for a few years. They have industry-leading cameras, get speedy software and security updates directly from Google (like iPhones do from Apple), and are priced competitively. But choosing the right model can be tricky. Should you get the Pixel 7A? The Pixel 8? What about the crazy-expensive Pixel Fold? 


Don’t fret—here we break down the differences between the best Pixel phones battery and sort out the right one for you. We also have Pixel-exclusive tips to help you get the most out of your new phone, and we recommend some cases and accessories we’ve tested if you want protection.
Updated October 2023: We’ve added cases from Spigen and Burga.
The Best Pixel for Most People


The Pixel 7A (8/10, WIRED Recommends) is our top choice for most people because it has pretty much everything you need, setting a new standard for mid-range smartphones. (Though it is a little pricier than the Pixel 6A from 2022 .) This iteration includes wireless charging, which is really uncommon for phones under $500. You also get a 90-Hz screen refresh rate, which makes the onscreen interactions look and feel more fluid, as there are more frames per second than before. 
Its design and build are similar to its predecessor, though Google claims the aluminum mid-frame is slightly more durable. There’s Gorilla Glass 3 on the front 6.1-inch screen, which isn’t as scratch-resistant as the glass on pricier Pixels, but at least the rear is a plastic composite that won’t crack. This model comes in Charcoal, Sea, and Snow, but a Google Store-exclusive Coral has caught my eye.  


You won’t run into any problems with performance. It’s powered by Google’s Tensor G2 chipset, which is the same one that’s inside the Pixel 7 series. It’s plenty fast for everyday tasks and most mobile gaming, and it also allows for a few new software tricks, like Photo Unblur, which can use machine-learning algorithms to unblur people’s faces in those late-night pics. (It actually did this really well when I tried to capture a photo of a bride and groom on the dance floor!)
Speaking of the camera system, a 64-megapixel sensor leads the pack joined by a 13-megapixel ultrawide, and while these are not as good as the cameras in the Pixel 7 , the results are nearly imperceptible (you have to look really close) It’s easily the best camera phone for the money, whether you’re using it in low light to capture the stars or shooting a landscape on a sunny day. 


One reason we recommend Pixel phones is that they include many great software features that are genuinely helpful. We’ve collected most of them below, but my favorites are Assistant Voice Typing for much faster and more accurate voice transcriptions using the built-in keyboard; Now Playing to find out what music is playing around me; and Call Screen, which has pretty much stopped all spam calls coming my way. You’ll also get five years of security updates, so your Pixel 7A will be supported for quite a while Unfortunately, Google promises only three OS upgrades.


The only things that are iffy on the Pixel 7A are the fingerprint sensor, which isn’t as snappy or reliable as I’d like, and the battery life. The 4,385-mAh cell can take you through a full day of average use, but on busy days you will most likely need to top up before the sun goes down. There’s also no microSD card slot or headphone jack, so you’ll have to look elsewhere if you want a phone with those features. 
Works on all three major US carriers.


Best Pixel Upgrade
If you want the latest and greatest, then go for Google’s Pixel 8 and Pixel 8 Pro (7/10, WIRED Recommends). These flagships are slightly more expensive this year, but they’re the only Pixels to receive a software commitment of seven years. That’s right, Google is finally promising seven years of security and Android OS upgrades to these phones, outclassing all its Android peers. That even includes stocking up on spare parts for repairs to the hardware. 


The 8 series has the brightest OLED displays ever on a Pixel, which means no need to squint when staring at the screen on a sunny day. They have a more rounded design that makes ’em comfy to hold, though this is more evident on the 6.2-inch Pixel 8, which is smaller than its predecessor. It has a glossy glass back, whereas the 6.7-inch Pixel 8 Pro has a matte soft-touch glass back. Both have 120-Hz screen refresh rates, but only the Pro model can adjust this from 1 Hz to 120 Hz depending on what’s on the screen, which is more battery-efficient. 


These phones now have secure Face Unlock, making them the first since the Pixel 4 to have a biometric authentication tool like Apple’s Face ID. You can use your face or the in-display fingerprint scanner to access sensitive apps like your banking app. It just doesn’t work well in darkness, so you’ll still have to rely on your thumbs. 
Inside is Google’s Tensor G3 processor, which hasn’t given me any trouble with any  of the apps or games I threw at it. It remarkable powers new smart imaging features, like Magic Editor, which lets you move subjects around in your photos and even change the type of sky; Best Take, for fixing people’s faces in case they blinked and Audio Magic Eraser, to remove unwanted sounds like a fire truck’s siren from video clips. I go into a little more depth about these features in this story.


The cameras have been upgraded all around, too. The Google Pixel battery Pixel 8 has a 50-MP main camera that crops into the center to offer a high-quality 2X zoom. There’s also a 12-MP ultrawide now with autofocus, allowing it to utilize Google’s Macro Focus for close-up shots. 


The Pixel 8 Pro has the same main camera but an upgraded 48-MP ultrawide that lets you go even closer to subjects for Macro Focus, and it’s overall more effective in low light. You still get a 48-MP telephoto 5X optical zoom camera, and the Pro also exclusively has a front-facing camera with autofocus, allowing for sharper selfies. It’s the only one with Pro camera controls in case you want to have more control over your photos, and it will eventually get a new feature called Video Boost , which will send your clips to Google’s cloud servers for processing—you’ll be sent back footage that is brighter with better stabilization, less noise, and brighter colors. 

The 4,485-mAh and 5,050-mAh Google Pixel battery batteries in the Pixel 7and Pixel 7Pro aren’t anything to write home about. With average use, you can expect them to last a full day, but anyone using their phone heavily will want to carry a power bank. At least they can recharge slightly faster. 

Samsung Galaxy S21 vs Galaxy S21 Ultra: Final Verdict

This year Samsung once again chose not to release a single flagship phone . Instead, we got three phones, theGalaxy S21, Galaxy S21 Plus and Galaxy S21 Ultra, each with unique additions, sacrifices and prices. 


While Samsung’s range isn’t quite as varied as the massive iPhone 12 line, but each is still different enough to make knowing which is right for your needs and budget a little tricky.
Here to help we’ve created this guide detailing everything you need to know about the top and bottom entry into Samsung’s 2021 flagship line, including our real world findings testing the S21 and S21 Ultra.


Pricing and availabilityLet’s start with pricing. All models of the S21 are cheaper than the outgoing S20 models.
The starting RRP of the Samsung Galaxy S21 Ultra is £1149/€1249/$1199, which is marginally less than the Galaxy Note 20 Ultra 256GB model and more than the iPhone 12 Pro Max. 
The Samsung Galaxy S21 starts at £769 €849/$799. This is a big reduction over the outgoing Galaxy S20. By launching at £799, Samsung undercuts the price of Apple’s iPhone 12 in some regions.


The Samsung S21 Plus will cost from £949/€1049/$999. Again, this price is slightly lower than that of the S20 Plus, which retailed for £999/€1099 at launch.
All three models are available to pre-order now and will ship on January 29. This is the earliest Samsung has ever released a flagship S series phone and it’s one of the first big phone announcements of 2021.
Both the S21 and Ultra have the same overall look. This means that on both phones Samsung has successfully built the camera module into the design, making it stand out more and cling to the top corner. The only big difference is that the S21 and S21 Plus have a smaller camera panel as they have fewer sensors, with the Ultra needing more space for its impressive lens setup.


All three phones have IP68 water and dust resistance rating, a USB-C port on the bottom for charging, stereo speakers and a small cut-out on the display for the front camera. They also all boast a new, much larger optical fingerprint scanner that is built into the screen. We can’t state how much better this optical sensor is than the one of the S20. During testing we found it offers far better accuracy and speed.
There are a few big differences, though. Size and weight are one of them, with the Ultra tipping the scales at a whopping 228g. For comparison, the Galaxy S21 weighs 172g. Check the table below for full dimensions.


One reason for the much lighter Galaxy S21 is that it ditches the glass on the back for plastic, Both other models have glass rears.
You do feel this change when you pick up the Galaxy S21. While the plastic is nice enough, it lacks that high-end finish you get with metal or glass. Considering this is Samsung’s  phone line, the change is a bit of a shame .
The S21 Ultra is the largest phone and as such has the biggest display. Here you’ve got a 6.8-inch curved panel, whereas the S21 Plus has a flat 6.7-inch screen and the smallest S21 packs a flat 6.2-inch version.


There’s more to differentiate the displays than just size. The S21 Ultra has a max brightness of 1500 nits, packs a WQHD+ resolution and an adaptive refresh rate that cycles from 10Hz-120Hz depending on what you’re doing. Unlike the S20, these two options can be utilized at the same time.
If you’re watching a YouTube video, for example, it’ll refresh less than if you’re playing Fortnite. This helps save battery as it ensures you’re not wasting energy when you don’t need to.
There are no two ways around it: this is the best screen on any phone we’ve ever used. It’s ridiculously sharp, pleasingly colorful and an absolute star if you’re streaming HDR video through YouTube or Netflix.


The S21 and S21 Plus also have adaptive 120Hz displays, however they can only drop to 48Hz. They both also have slightly lower FHD+ resolutions – quite an odd move for a series that usually sticks to the best possible screen. The screen here is still good , just not in the same league as the Ultra or even the iPhone 12 series, when we used them.
Specs and cameraS21 has 8GB RAM and 128GB/256GB storage; Ultra models up that to 12/16GB and up to 512GB storageWant the best camera? Go for the UltraS21 has cameras similar to the S20The Samsung Galaxy S21 Ultra lives up to its branding (and price) by packing in a wealth of top end hardware. Choose this model if you want the most RAM and the biggest storage sizes. 


For instance, RAM on the Ultra model is either 12 or 16GB, with storage options coming in at 128GB, 256GB and 512GB. It’s also the only model to support the S Pen stylus traditionally seen on Samsung’s Note line of phones.By comparison, both the Samsung galaxy  batteryS21 and S21 Plus have 8GB RAM and either 128 or 256GB storage.
You’ll find the same chipset inside all phones, so even if you plump for the cheapest version it’ll still be seriously fast. In the US the chipset of choice is the Snapdragon 888, while us in the UK and certain other markets wi ll have Samsung’s own Exynos 2100. 
All versions of the S21 we have tested are quick, and we didn’t notice any issues with the smaller amount of RAM on the cheaper model. However, the lack of expandable storage and no 512GB option mean that if you’re shooting lots of 8K video you will see that storage deplete very quickly. We’d recommend going to the 256GB model, just to be safe, as a result.


In terms of benchmarking scores, both the S21 and S21 Ultra are on par. You won’t get better gaming performance on the S21 Ultra, aside from the extra freedom afforded by the bigger, far better display.
Where the Ultra mode does come out firmly on top is with its camera and this is firmly the best camera phone you can buy right now. The Galaxy S21 Ultra has a wildly different camera array to the S21 and S21 Plus, with an extra zoom lens along with more pixel-packed sensors. Here’s a quick overview of the Ultra camera specs:

Moving over to the S21 and S21 Plus, these have more modest specs and we found the S21 camera took virtually the same kinds of pictures as the outgoing S20 model. This isn’t necessarily a bad thing – the S20 had one of the best cameras around when it was released – but a year later and the S21 can’t compete with the iPhone 12.
Battery lifeThe bigger battery on the S21 Ultra gives it more staminaAll S21 phones ditch the chargerWired charging peaks at 25wInside the Samsung Galaxy S21 Ultra, you’ll find a 5000mAh cell, 4800mAh for the S21 Plus and 4000mAh for the S21. All three phones can be charged at 25w wired and 15w wirelessly. They also all pack Reverse Powershare for charging up accessories.


None of the phones comes with a charger in the box though, just a USB–C cable, so you’ll need to use an older USB-C charger or to buy one separately. If you’re upgrading from something like the Galaxy S10 or Galaxy S9 then that plug is not capable of providing full charge speeds to these phones.
The Galaxy S21, on the other hand, is more modest and not much of an upgrade over the outgoing S20. In fact, you could say it is a downgrade thanks to the less premium materials used, lower resolution display and use of the same camera array. But, it’s important to see the S21 as more of a device for those who have much older phones and aren’t interested in blowing over a grand on a new phone. For this market, the Galaxy S21 is an ideal phone at a great price. ll have Samsung’s own Exynos 2100.

Which Motorola Phone Should You Buy?

IF SOMEONE ASKED what kind of pet you want Motorola’s phones are hamsters in this analogy.Still cute and definitely pets, but not necessarily the first or second one that comes to mind. The company’s Android  Cell Phone Batteries often play third fiddle to the likes of Samsung and Google.

And if you’re an interested buyer, it can be hard to select the best Motorola phone because the company launches way too many models in a year. I’ve tested almost every Moto phone, and in this guide I break down the pros and cons and steer you toward my favorite models.  
The Pros and Cons of Buying a Motorolafront and rear view of the Motorola Mot G Power 5G smartphones


Here’s what’s WIRED and TIRED about Motorola phones. This breakdown can help you decide whether to stick with Moto or buy something else. 
What’s WIRED About Motorola Phones Motorola phones  batteryhave a simple Android interface. This means the company hasn’t done much to gunk up the software. It’s simple and easy to use. There’s often some bloatware, but nowadays you can easily uninstall almost all of it. 


These phones come with 256 gigabytes of storage. This isn’t true of every Motorola phone, but most now offer more than the 128-GB capacity you’ll find on their peers.
They have some of the best battery life. The company stuffs big batteries into these slim phones, and they’re frequently able to eke out two full days of use on a single charge, besting almost all of the competition. 
There’s broad carrier support. While some Android phones have inconsistent carrier support in the US, Motorola phones often work on most if not all networks (the company lists carrier support details in the Specs section of all its phones). They all work on the big three—T-Mobile, AT&T, and Verizon. Make sure you buy them unlocked. 
The prices dip quite often. Never buy a Motorola phone at its MSRP. They almost always go on sale a few months (or even weeks) after launch, sometimes at steep discounts. 


What’s TIRED About Motorola PhonesMotorola’s software updates are lackluster. The company is slowly improving here—it promises to deliver three Android OS updates and four years of bimonthly security updates to its high-end smartphones—but it still lags behind its peers. Worse yet, the phones in the Moto G series only receive one OS Android update (with three years of security updates), so they miss out on new Android features fairly quickly.
Moto G phones lack NFC. Near-field communication sensors are what enable tap-to-pay on your phone, allowing you to use contactless payments at participating retailers. Phones as cheap as $200 have this feature, but Motorola is notorious for excluding it on (most) of its Moto G range. 


The cameras are lackluster. Among the things Motorola behind the likes of Samsung putting and Google are the cameras. They can take fine photos, but they’re easily eclipsed by the competition.
There’s no always-on display. Most Android phones have a setting you can toggle on if you want an Always-on Display that will show a clock on your screen even when the screen is “off.” Motorola has Peek Display, which requires you to move the phone or tap the screen to see anything. It’s not a big deal, but that’s a feature you might miss if you’re coming from another phone. 
Best Motorola PhoneThe best Motorola phone right now is the Motorola Edge+ (2023). It’s a tall, narrow device with a 6.7-inch OLED display that curves into the edges for a more immersive screen. I usually dislike these kinds of “waterfall displays” because my fingers tend to disrupt the screen, but I didn’t have many issues on this phone. 


The Full HD+ screen is sharp and colorful, it gets bright enough to view on sunny days, and the refresh rate can ratchet all the way up to 165 Hz. It makes the screen look and feel more responsive, though I set it to 120 Hz , which is plenty for me and doesn’t suck up as much battery. The back of the phone has a glistening design that looks snazzy, and both the front and back are protected by the scratch-resistant Gorilla Glass Victus.
The Edge+ impresses with its raw specs. It’s powered by the latest Qualcomm Snapdragon 8 Gen 2 processor (along with 8 GB of RAM), which is what powers most high-end Android smartphones right now, and I rarely saw stutters, even with the most demanding apps and games. 


There are dual stereo speakers at the top and bottom of this device to pump out loud tunes that sound pretty good, NFC for making contactless payments, dual SIM support, IP68 water resistance, and a whopping 512 GB of storage—well more than you’ ll find on any other smartphone at this price. There’s no microSD card slot to expand that storage, nor a headphone jack in case you want to plug in. 


Most impressive is battery life. There’s a 5,100-mAh cell, and this  Motorola cellphone Battery easily lasted two full days of average use. Even heavy users should expect to get through a full day without requiring a top-up. When you do need to recharge , you can use the included 68-watt charging adapter or a wireless charger. Motorola is one of the few phone makers to still include a charger in the box. 


Where it loses points is the camera system. A 50-megapixel primary camera is joined by a 50-MP ultrawide and a 60-MP selfie camera. In my photo comparisons, the Edge+ took some sharp shots, but it had a hard time keeping up with the $499 Google Pixel 7A. Motorola’s results are often oversaturated and overly brightened, and they tend to deliver slightly off skin tones. In low light, I frequently had to retake photos because the first result was blurry. If the camera is important to you, I’d avoid buying any Motorola phone. Consider the Pixel 7A or Samsung Galaxy S23 instead.

Motorola Phone battery  Android OS upgrades promises four years of bimonthly security updates.  

Samsung Announces Another Cell Phone Battery Recall

Just when we thought the issues with overheating Samsung batteries had passed, the company has announced a recall of about 10,200 lithium-ion batteries because of overheating, fire, and burn hazards.
The US Consumer Product Safety Commission (CPSC) announced the recall on August 16, 2017, noting that these are batteries that have been placed in refurbished phones.
Samsung Recalls Batteries in Refurbished PhonesCustomers who are using refurbished AT&T Samsung Galaxy Note 4 cell phones distributed as replacement phones through AT&T’s insurance program may be affected. Samsung has determined that some of the recalled SamsungSmartphone Battery batteries are counterfeit and show anomalies that can lead to overheating. The phones were provided as replacement phones between December 2016 and April 2017.
Samsung has advised consumers to stop using the batteries immediately, and to power down their cell phones. Then they should expect to receive by mail from FedEx Supply Chain a free, new replacement battery and a postage paid box to return the recalled battery. Consumers can identify the new, replacement batteries by a green dot that has been affixed to them.
So far, there have been no reports of property damage or injuries related to this recall.
Samsung Recalled One Million Phones in 2016Back in September 2016, the CPSC announced the recall of Samsung Galaxy Note7 smartphones, because they contained lithium-ion batteries that could overheat and catch fire. The phones were sold before the recall date at stores nationwide, including AT&T, Best Buy, Sprint, T-Mobile, US Cellular, and Verizon.
Prior to the recall, Samsung received 92 reports of the batteries overheating, including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage. The recall affected about 1 million units, and Samsung promised free replacements for consumers.
In January 2017, Recode Media reported that after months of investigating, Samsung had concluded that there was nothing wrong with their Galaxy Note7 phones, but instead, they discovered flaws with the batteries themselves. In one, a design flaw caused the electrodes to bend, which could lead to a connection between the positive and negative tabs, causing a short circuit.
In a second battery Samsung obtained from another provider, a manufacturing issue led to a welding defect that prompted the battery to short circuit and ignite.
Manufacturers Responsible for Battery SafetyIt’s not only phones struggling with lithium-ion batteries. Other devices, including e-cigarettes and hoverboards, have been in the news because of overheating-related incidences and injuries. These batteries are popular because they store a lot of energy in a small space , so they work well for powering many different products, but they are naturally vulnerable to short-circuiting and over-charging. They are also filled with a flammable substance that can explode when it gets too hot.
As technology continues to move forward at breakneck speeds, manufacturers must take steps to make sure their batteries are safe. Proper protection Samsung Cell Phone  batteries can reduce the risk of short-circuiting and overheating, while increasing resistance to physical abuse.
