One of the power-hungry features of the iPhone 15 Pro and Pro Max is the 120Hz ProMotion display. This dynamically adjusts the screen refresh rate between 1Hz (which is always displayed when the phone sleeps) to 120Hz for things like scrolling content and gaming.

But if you want to maximize your phone’s battery life, is it worth turning off the feature? New tests show no…

You can limit the refresh rate to 60Hz using the settings in Accessibility, which will prevent the display from going up to those high refresh rates that drain battery power. Of course, this also means you don’t get the smooth scrolling and animations of ProMotion , so you’re giving up one of the key features of buying a “Pro” iPhone. Maybe if the Apple cellphone battery life was longer it would be worth it?

He first conducted a Geekbench 4 battery test, and the results showed that the smart iPhone battery life increased by about 5%. A less scientific but more realistic test showed similarly small differences. As he concluded, it’s important, but not enough to give up ProMotion’s smoothness.

He said you do see a big difference when you play games that support 120fps.
Shooting games “Call of Duty: Mobile” and “PUBG” mobile support high refresh rates, and games such as “Brawl Stars”, “League of Legends: Wild Rift”, “Genshin Impact” and “Alto’s Odyssey” High refresh rates are also supported.

In most of these games, you have to turn on the in-game options to select a special 120fps or high frame rate mode.
It’s impossible to do any scientific testing here because there are so many variables, but he said that as a rough guide, he noticed that when ProMotion was turned off, battery usage was roughly cut in half. This is because high frame rates impact Apple battery life through more intensive GPU usage and faster frame rates.

This is obviously a huge gain, and something you might consider if you do a lot of mobile gaming without battery, but in general you don’t need to turn ProMotion off – as 120fps is usually what you need in every game Something that is actively enabled.
So unless 5% charge affects whether your iPhone battery lasts all day, enable ProMotion. If you’re a gamer and want to saveiPhone battery, just turn off high frame rates when playing without a power outlet handy.

Apple today published an open letter on its website apologizing for how it handled performance on iPhones with older batteries, specifically “how we have communicated that process.”
We’ve been hearing feedback from our customers about the way we handle performance for iPhones with older batteries and how we have communicated that process.

We know that some of you feel Apple has let you down. We apologize. There’s been a lot of misunderstanding about this issue, so we would like to clarify and let you know about some changes we’re making.

To make up for the confusion, Apple is offering cheaper battery replacements and says a future iOS update will include features that offer more insight into battery health.
Apple says it will reduce the cost of  Apple replacement cell phone battery for anyone with an iPhone 6 or later from $79 to $29. The price drop is temporary and will begin in late January and run through the end of 2018. More details will be available soon , the company says.

Apple is reducing the price of an out-of-warranty iPhone battery replacement by $50 — from $79 to $29 — for anyone with an iPhone 6 or later whose battery needs to be replaced, starting in late January and available worldwide through December 2018. Details will be provided soon on apple.com.
Furthermore, the company says it will release a new version of iOS in 2018 that offers users more insight into their battery’s health:
Early in 2018, we will issue an iOS software update with new features that give users more visibility into the health of their iPhone’s battery, so they can see for themselves if its condition is affecting performance.

Apple’s letter also attempts to dispel the idea that it intentionally slows down older iPhones to shorten their life, but rather delivers products that last as long as possible:
First and foremost, we have never — and would never — do anything to intentionally shorten the life of any Apple product, or degrade the user experience to drive customer upgrades. Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that.
The letter also offers more color on how batteries age, with Apple explaining that all rechargeable batteries are “consumable components that become less effective as they chemically age.”

Device use also affects the performance of a battery over its lifespan. For example, leaving or charging a battery in a hot environment can cause a battery to age faster. These are characteristics of Apple battery chemistry, common to lithium-ion  batteries across the industry
A chemically aged battery also becomes less capable of delivering peak energy loads, especially in a low state of charge, which may result in a device unexpectedly shutting itself down in some situations.

Apple’s apology here is notable and comes following a wave of confusion and frustration from users who feel that Apple misled them. It all started earlier this month when evidence began to mount that Apple was slowing older iPhones in relation to battery performance, and the company was forced to confirm the practice shortly thereafter.
Since confirming that it slows down older iPhones, Apple has been hit with numerous lawsuits.

How long do iPhones last? Many factors can play into deciding when it’s time to get a new phone. We’ll look at how long an iPhone will get iOS updates before it’s not supported anymore, the typical lifespan of an iPhone, and other lifestyle factors that might influence your decision to buy. We’ll also take a look at the best time to buy a new cell phone, so you can get the most out of your new purchase.

Many people see a decline in performance around the two-year mark. A lot of this can depend on wear and tear, along with how many times you’ve dropped your iPhone, but since this seems to be a pretty consistent trend for most iPhone users, I think two and a half years is a more accurate measure for how long your iPhone will work well.
Some people keep their iPhones for five years or more before they squeeze out that last drop of life, and a lot depends on how many trips to the Genius Bar you’re willing to make and how much you want to spend on new batteries, screens , and other physical parts. So how long does an iPhone last? Overall, you can expect a regular iPhone to be in your life for somewhere between two and three years. If your iPhone 14 is still working fine, you probably don’t need an iPhone 15 (but that doesn’t mean you can’t upgrade if you want to). On the other hand, if you’re rocking an iPhone 11 or 12, an upgrade might make more sense.

When Should I Buy a New iPhone?
So your iPhone isn’t working great, but it’s still usable. Maybe you’re staring at the old thing on your desk and wondering, “how old is my iPhone?” Or maybe a new iPhone model has caught your eye but, as Mom used to say, you have a perfectly good one at home. Whatever your reason for wondering, it can be hard to finally tell yourself, “I need a new phone.” It’s a big commitment and can also be a hassle. So, we’ve compiled a list of signs that it is indeed time to get a new iPhone.
Performance DeclineSo your iPhone doesn’t work. Or maybe it works, but it doesn’t work well. Once you start to run into consistent, noticeable performance issues, it’s time to start looking at new phones. A few years back, I ignored worsening issues with my iPhone until one night, I got stuck in an endless loop of a restart screen and had to officially call it quits. Not only did I lose two years’ worth of photos (always back up your iPhone, folks), but I was also stuck without a phone at all until I was able to get a new one. Since I hadn’t budgeted for a whole new iPhone yet, the cost of a new iPhone took me by surprise. Once your iPhone starts glitching regularly, prepare for a new iPhone purchase. Even if you can get another few months or even a year out of it, you’ll be happy you planned ahead.

Battery Lifespan DeclineThis is one of the biggest motivators for users who decide it’s time to buy a new iPhone. How long do iPhone batteries last? The answer can vary wildly, depending on a variety of factors, like usage, keeping it plugged in overnight, or if you’ve simply had the phone for a long time. But once it’s gone, there’s really no getting back the loss of your iPhone’s battery lifespan. You can replace your iPhone’s battery, but oftentimes a worn-down battery goes hand-in-hand with other performance issues that may make you want to throw in the towel.

If the latest iOS update doesn’t support your iPhone, it’s time to get a new one. Sure, one missed upgrade might not seem like a big deal, but you’re going to be falling behind on performance quickly, and apps that are updated to run on the new OS might not work well or at all anymore. More importantly, iOS updates usually come with important security updates, so running out-of-date operating systems on your iPhone is less secure. There’s little to no point in keeping a device that isn’t supported by the latest iOS. However, keep in mind that Apple will continue to support most iPhones for a long time. For example, the iPhone 8 (released in 2017) received new iOS updates for five years up to iOS 16.

Physical DamageOur iPhones can take a beating, but sometimes the damage proves to be too much. If you’re trying to see through a shattered screen that you’ve decided it’s not worth it to fix, or if a button is permanently broken, your frame is coming apart, or anything is held together with duct tape, now is when you want to make that new phone investment. Remember when that first scratch on the body felt like true heartbreak? Chase that feeling. You’ll be glad you did.

But keep in mind that you don’t need to wait until your iPhone is falling apart to get a new one. If you take good care of your iPhone, you can get good money on a trade-in to Apple when you finally spring for the newest model. Apple won’t accept any trade-ins with body damage, including cracked screens, so keep that in mind when planning when to get a new phone. say, “Upgrade my phone!” and be provided with an array of free and reduced-price cell phones in exchange for another two years of loyalty. Now, these kinds of deals aren’t as common, but most providers offer a free iPhone at some point. Keep an eye out for BOGO deals and special offers around new iPhone launches (usually in early fall each year), and you might find yourself in luck. If a carrier’s offer to provide a free second iPhone with any iPhone purchase coincident with a friend or family member deciding they need a new phone, go for it. If you’re eligible for a free phone, that’s always a good reason to upgrade.

A New Phone Model Satisfies an Unmet NeedMaybe you don’t need a new iPhone, but you do need a new feature on one of the latest iPhones. Whether it’s a smaller size for easier one-handed navigation, a bigger size for screen easier viewing, 5G support, or an upgraded camera, if a new iPhone meets a need your old one doesn’t, go ahead and spring for it. Keep up to date with launches and new features, and you’ll be able to easily distinguish between want and need. That being said …

It’s okay to buy a new iPhone just because you want it. Really. If you can afford it, wanting the latest model is a totally fine reason to buy it. If you’re feeling guilty about waste, you can always give your still- Perfectly good old one to a friend, or even donate it!
The Best Time to Buy a New iPhoneGenerally, the best time to buy an iPhone is during or after the launch of the new line, which typically happens in the fall, around September. If any price drops happen on the older models it will happen after the launch of the new ones, and if the price doesn’t drop, you might as well see what the new ones are. Sometimes the new models are comparable in price to the old ones or offered for free as part of special carrier deals. It’s a frustrating feeling to buy a new iPhone in July or August only to find out a couple months later that you could have gotten one with much better features for the same or lesser price!

The bottom line is, the best time to buy a new iPhone is when you need one. Don’t let the seasonality keep you from investing in yourself in a way that really matters. While you’re considering such things, why not check out what you should do before selling your current iPhone? Happy upgrading!

………………………………………………………..apple mobile phone battery

It’s no exaggeration to say that your entire life is essentially on your iPhone, which means when your battery dies , it can be extremely inconvenient and even catastrophic. Keeping your iPhone charged is an absolute necessity, so have you ever wondered how you can get more out of your battery? Read on to learn how your trusty handheld device can stay charged and ready.

How the iPhone battery worksApple’s mobile batteries use high-density lithium-ion cells designed to store a lot of energy in a small space, resulting in an extremely thin battery that charges quickly and is great for maintaining its overall health. They also don’t receive a constant current throughout the charge; the first 80% charge fairly quickly and the last 20% much slower. This fast/slow system ensures you get power quickly when you need it, while avoiding short circuits in the battery and ultimately extending its long-term life.

In fact, the iPhone’s battery is much more powerful than you think. It’s designed to retain 80% of its original capacity even after multiple charge cycles, allowing even devices that are years old to retain their charge, depending on how the battery is cared for Still, when your phone starts draining battery faster, you may find yourself sorely lacking that extra 20% capacity – for example, you’ll regret it if you’re in an unfamiliar city and find yourself unable to plot any routes. Use your dead phone a little
That said: There are a lot of misconceptions out there about how best to extend your Apple   Cell Phone battery battery life. We’ll go over some of them below, so you actually have a grasp on how to keep your devices powered and in top condition.

1. “The battery should be exhausted before charging.”While this may be sound advice for older devices and cameras, iPhones are unique in the way they calculate charge cycles. By tracking a full charge from 0% to 100% (rather than every time you plug it in), your iPhone can accurately assess the health of its lithium-ion battery. Charging your phone for a few minutes doesn’t count as a complete “cycle,” but fully discharging and charging does affect the overall battery health measurement.

In other words, waiting until you plug your phone in when it’s close to 0% charge actually puts more stress on your battery life than charging it frequently.
2. Do not leave the phone plugged in when theApple battery is fully charged.Good news – you don’t need to worry about your battery wearing out from being plugged in all the time, especially since overnight charging is the best time to charge. iPhone’s power management technology is smart enough to stop the flow of electricity when the battery is full, so you can keep it charged overnight without worrying about shortening its lifespan.

3. “Disable Wi-Fi and Bluetooth, and close unused apps to extend battery life.”Not really: The technology behind wireless connections like Bluetooth and Wi-Fi has come a long way in the past few years, so they don’t require nearly the same energy as before. Therefore, disabling these settings will worsen your device experience without significantly extending battery life.

5 sure-fire ways to extend your iPhone’s battery life1. Turn down the brightness of your iPhone’s displaySince the process of lighting up the display uses more power than any app, adjusting your iPhone’s auto-brightness setting is a great way to reduce battery usage. Auto-brightness dims the screen based on the amount of ambient light

2. Enable low- power mode in iOSLow Power Mode was added to iOS 9 to squeeze every last drop of power out of your iPhone by limiting power-hungry background processes. Normally, it’ll ask to activate when your battery drops below 20%, but you can always activate it manually if you’re having a long day. To toggle low-power mode, just go into Settings > Battery and flip the switch.

3. Update iOS to the latest versionKeeping iOS up to date is generally a sound approach, as each system update is bound to fix bugs and improve performance. When your phone runs efficiently, your battery has to do less work to keep everything running smoothly.

4. Avoid using iPhone in extreme temperaturesUsing your iPhone for extended periods of time in freezing weather or under strong direct sunlight will inevitably damage the battery. While it won’t damage your device, battery capacity will decrease with greater exposure to extreme heat and cold temperatures. Try to keep your phone as close to room temperature as optimal possible for iPhone battery life and performance.

Everyone knows that cell phones have to be charged regularly in order to keep working,but did you know that the way you charge your phone has an impact on how long the battery lasts? It’s true. Simple things like over and under-charging can actually shorten the life of your apple cell phone battery . The good news is you can keep your battery going strong by following a few basic rules. Here are our top tips for charging your cell phone properly.

What is a Cell Phone Battery Charge Cycle?Most cell phones today run on lithium-ion batteries. 

Lithium-ion batteries work in charge cycles. You complete one full charge cycle when you’ve used (or discharged) an amount of power equal to 100% of your battery capacity. If you use 75% of your battery’s capacity on Monday, then recharge it fully overnight and use 25% of its battery capacity the next day, your total usage for the two days will add up to one full charge cycle.

The life cycle of your cell phone battery is also measured in charge cycles. A new lithium-ion battery will typically last between 300 and 500 charge cycles. This is where your charging habits come into play. Usually, a cell phone battery lasts between two and three years, although the frequency with which you charge it plays an important role in how quickly you burn through those cycles.

What is the Correct Way to Charge a Phone?

Follow these basic tips to make your charge cycles last longer and get the longest life possible from your battery.
1. Don’t Charge Your Cell Phone OvernightWhen you keep your phone plugged in overnight, you’re keeping it on the charger for much longer than is needed. If a battery becomes overcharged, it can become damaged. In order to prevent this, your cell phone will start to discharge the battery slightly. Then, after the charge drops too low again, it will begin to charge it back up again. This constant cycle of discharging and recharging causes your battery to burn through its total number of charge cycles much faster, shortening the battery’s overall life.

2. Don’t Charge Your Cell Phone to 100%While it sounds counter-intuitive, continuously charging your cell phone battery all the way to 100% is something you should avoid. A battery that contains a higher voltage is placed under more stress than one running at a mid-range capacity of 40% to 80% state of charge. This stress can degrade the battery by wearing down its internal chemistry. Ideally, you should only charge your cell phone to 100% if you intend to remove the phone from its charger and begin using it within a few hours.

3. Don’t Let Your Cell Phone Battery Drop Down to ZeroWhile overcharging is a problem, letting your cell phone battery run down all the way is also not good. Some people might tell you that your battery will lose part of its total capacity unless you run it down to zero. This is false. While it is true that nickel-cadmium batteries possess this “memory effect,” the lithium-ion batteries in your phone function quite differently. Discharging a lithium-ion battery completely can actually diminish its overall capacity, so it’s best to always keep it charged to 40 -80% of its total capacity.

4. Don’t Let Your Cell Phone Get Too HotAccording to the Apple website , cell phones and other devices are “designed to perform well in a wide range of ambient temperatures, with 62° to 75℉ (16° to 22°C) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 95℉ (35℃), which can permanently damage  Apple battery capacity.”

Exposing your cell phone to high heat on a regular basis can impair the battery’s ability to hold a charge. Remember how we mentioned that keeping your phone at 100% capacity puts it under increased stress?

Well, those stresses are magnified even further by extreme heat That’s why it’s important to avoid charging a cell phone in high temperatures. If you notice that your phone has gotten excessively hot, there are a number of steps you can take to cool off your phone.
How Can I Tell if My Phone Battery is Dying?On average, a cell phone battery should last between two and three years. After that, it will likely begin to have a negative impact on your cell phone’s performance. Here are a few common symptoms of a dying cell phone battery:
Needing to charge your phone multiple times in one dayThe phone won’t charge completelyPhone charge drops immediately after being removed from the chargerBattery drains too quicklyPhone randomly crashesYou notice a slower performance from your iPhone

To make room for the Face ID notch, Apple removed the old battery percentage number from the iPhone home screen . But there are still ways to get this useful information when you need it.

The battery icon in the upper right corner of your iPhone screen can be very useful in a pinch. For example, it will tell you whether your phone is fully charged, so you can rest assured. Or in a more common case, it will show you that the iphone battery is about to run out. It’s just that between those two extremes, it’s not that useful – it’s not nearly as helpful as a charge percentage number. 
Of course, you can’t tell from the icon whether the battery is dropping unusually quickly. Instead, it’s important to be able to see that you’ve improved from 100% to 95% the moment you walk out the door.

When we got the Face ID notch on the iPhone X, we lost   Apple battery percentage and all status icons were pushed to the left or right. You’ll notice that the iPad and iPad Pro retain the percentage numbers, but that’s because they don’t lose devices like the iPhone X, iPhone XR, iPhone XS, iPhone XS Max, iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max About half of the top area. Rumors suggest we’ll see a smaller notch in 2020’s “iPhone 12 ,” which could lead Apple to give us that percentage number again .

For now, though, it’s hard to argue that Apple was wrong to ditch that percentage given the smaller space available, since it does retain the battery icon, as well as Wi-Fi and cellular data. We won’t swap the last two, but it would be better to replace the battery icon with a percentage.
However, you can still find out the exact percentage of charges if needed. There are several ways to do this, and if none are more convenient than simply glancing at the top of your iPhone screen, then one of these methods will work for you.
Use control centerDepending on what you’re currently doing with your phone, in most cases the fastest way to check your battery level is through Control Center.
Battery charge percentage is always located in the upper right corner of Control Center
Swipe down from the top right corner to launch Control CenterRead the battery percentage in the upper right cornerThat’s it. No matter what app you are using, or even if you are not in the app, you can call up Control Center and read the percentage instantly.

Use notification centerSetup is required the first time you do this, but thereafter the battery level will be listed in your iPhone’s Notification Center. If you use this feature frequently, it might even be faster than going through Control Center.
Plus, it might also be more convenient, since the Notification Center version not only shows the battery level in your iPhone, but also lists your Apple Watch. It will also show your AirPods’ charge level if they’re connected and removed from the charging case or the lid of the charging case is open.
To set it up for the first time, do the following, starting on your iPhone’s first Home screen or Lock screen.

Swipe left to enter the notification centerScroll all the way down to the bottom and click “Edit”Scroll down to the “More widgets” sectionFind the battery and click the green plus sign next to itThis will move the battery to the top area, which is the list of widgets shown in Notification Center. This is also a list showing the order in which they appear. So if you want to see the battery level at the top, do that.
Click on the handle to the right of the battery (three horizontal bars)Drag up to rearrangerelease when it’s in placeFinally, click “Done” to finish editing the widget.

Now that you’re set up to use Notification Center to show all your battery percentages, feel free to do the following when you want to know exactly how much power you have left.
Swipe left from the lock screen or first home screenRead cost percentageSwipe right to close notification centerTell you with SiriYou can also ask Siri at any time.
There are different ways to say it, but “Hey, Siri, how much battery do I have left?” always works.
You can also ask Siri on your iPhone to tell you how much battery is left in your Apple Watch. However, you can’t ask Siri on the Watch to tell you how muchApple Cell Phone  replacement battery is left on your Apple Watch.
Quick view while chargingIf you have a Qi wireless charger nearby, place your iPhone on it. Your iPhone’s lock screen displays the current battery percentage.
If you just plug your iPhone into the charger, it will do the same thing, but in both cases it will only briefly display the percentage.
Your iPhone briefly displays battery percentage when you put it on charge (left) or take it off again (right)

If you don’t notice in time, though, you can remove your iPhone from the charger, which will briefly display the battery percentage again.
There is another wayFor absolute completeness, we also tell you that you can create your own shortcut to display The same goes for fee percentages.
This is a particularly simple shortcut to create and display the percentage as a regular notification. This can be convenient as the notification can remain on your screen until you choose to dismiss it.

Plus, you can do more with the content you find using shortcuts. By default, your iPhone prompts you to enter low-power mode when it reaches 20%, but maybe you know that won’t get you through the rest of your day. You can create a shortcut that, whenever you run it, checks the battery and gives you the same low-power mode if it’s below 50%. In this case, you must actively choose to perform certain actions in order to find out your battery percentage . This will never be as convenient as browsing, but it seems unlikely that Apple will bring back this option anytime soon.

However, there is one thing. When Apple does offer the option to display battery percentage, it’s easy to get anxious about it. You can keep picking up the phone to check the battery level, but of course, this action will cause the battery level to drop. So even though you can now use all these different methods to find out your Apple batterypercentage, maybe you should avoid doing it too often.
