I love my new iPhone 14 Pro , but one of the things I realized when I first went to charge it using the wireless (Qi, non-MagSafe) charger on my nightstand is that it wasn’t going to work very well with that charger This was somewhat disappointing given that my wireless charger had been working perfectly with my iPhone 11; however, I realize a couple of things: 1) my charger was a fairly inexpensive purchase from a little-known brand and 2) sometimes new technology necessitates additional new accessory purchases. Despite the charging trouble, there are a few things you can do to get your wireless charger working with your iPhone 14 Pro.
In this article, I’ll tell you about my observations using four different wireless (non-MagSafe) chargers and five different cases. I’ll also give some tips for charging your iPhone 14 Pro on your wireless charger.

Why the iPhone 14 Pro has trouble with wireless chargersThe camera bump on the iPhone 14 Pro is especially large. Wireless (Qi) chargers depend on your iPhone being very close to the charging pad, and the large camera bump can prevent the back of your iPhone from getting close enough.

Exactly how well your iPhone 14 Pro will charge can depend on:
The wireless charger itself — the quality of the charger and the shape of the charging pad.The orientation of your iPhone.The case you are using on your iPhone. Many factors can come in here, including the thickness of the case, how deep the camera lens protection is and the shape of the case.Wireless charging test resultsI tried out four different wireless (non-MagSafe) chargers with five different cases from various case companies.

The four chargers included:
Two upright desktop/tabletop chargers.One charger that is built into a desktop.One wireless car charger.The cases were from Insignia, OtterBox and Speck. They include MagSafe and non-MagSafe cases, various thicknesses/drop ratings and one with a built-in PopSocket.

upside down orientationTry using a different orientation for your phone:Try upside downTry landscape orientation on the left or the right side.landscape orientation iPhone chargingTry removing the case. This is, of course, not an ideal solution; you won’t want to remove your case every time you go to charge your phone, but this could at least let you know what is possible with your current charger.Options to improve chargingAlthough some of the wireless (non-MagSafe) chargers I tested well with the iPhone 14 Pro, the best bet for charging your iPhone 14 Pro wirelessly is a MagSafe charger. There are many good options from both Apple and third-party sellers. design of these chargers is a small puck that attaches to your iPhone. The smaller size means that the camera bump shouldn’t be an issue, and you won’t have to fiddle with your iPhone’s placement on the charger — it will just snap into place.

If you purchase a MagSafe charging puck, you can use a non-MagSafe case on your iPhone, but your iPhone won’t “stick” to the MagSafe charger and so it may lose its charging connection if it gets bumped. okay for charging when the phone was correctly placed on the puck.Certainly for the kind of chargers that hold your iPhone up using MagSafe, you will need a MagSafe case so that your iPhone doesn’t slide off of the charger.

Find My is a great feature that can help you locate your Apple device if you have lost or misplaced it. But what do you do if Find My says Offline, No location found, No location available or Location Services Off? in Find My when your iPhone isn’t lost, or if you know it is around somewhere, you will want to know how to fix the problem. it is offline in Find My.

What does it mean when Find My says Offline?

When you are looking at Find My, either through iCloud.com or using the Find My app on another device, and your iPhone shows as Offline, this means that your iPhone is unable to communicate with Find My.
Reasons why your iPhone is offline in Find My may vary depending on which iOS version your phone is running. Find My was improved with iOS 15 (which became available in late 2021). Starting with iOS 15, Find My can still locate your device even if it ran out of battery or was turned off. It can also use Bluetooth or NFC to communicate with other Apple devices nearby to transmit its location. With iOS 14 and earlier, Find My might say Offline when out of battery or turned off.

Why Find My says Offline Here are some of the reasons Find My may say Offline:
The device is turned off or has run out of battery.The device is not connected to the internet.Airplane Mode may be on, cutting off Wi-Fi and cell signals.The SIM card may have been removed, cutting off cell signals.There are incorrect date and time settings.The device has a weak internet connection.There is no Find My support in the area (country).

Can I still find my iPhone?

If your iPhone says Offline in Find My and you still have your phone with you, there are things you should do to make sure Find My will be able to help you locate your iPhone in case you lose it in the future.

If you don’t still have your iPhone, there are a few things you can try to locate it.
What to do when Find My says Offline (and you know where your iPhone is)Update your iPhone to the latest iOS. Go to Settings > General > Software Update and install any available updates.find my  settings on iPhoneShare the device location with Find My. Go to Settings > [your Apple ID name] > Find My. Tap on Find My iPhone. Make sure Find My iPhone, Find My network and Send Last Location are on. For older iOS, go to Settings > Find My > Find My iPhone and Share My Location.Turn on Location Services. Go to Settings > Privacy & Security > Location Services.Turn off Airplane Mode.Make sure the date and time are set correctly. Go to Settings > General > Date & Time.If possible, switch to a more stable Wi-Fi or cellular data connection.Enable Bluetooth and Wi-Fi. Go to Settings > Bluetooth and Settings > Wi-Fi.How to locate your offline iPhoneSo the obvious strategies include looking for it in the real world:

Retrace your steps.Contact the locations you have been to.Contact local police if you are afraid someone may have taken it.There are still a few steps you take to find your iPhone, even if it is offline in Find My:
Check Find My periodically to see if it shows up. If you are running iOS 15 or later, your offline iPhone can still communicate with other Apple devices, and so if there are any nearby, you may be able to track the phone in Find My Also, if someone picked up your iPhone that had run out of battery or been turned off, they may charge it.Call your iPhone.If you use Google Maps on your iPhone, check Google Maps Timeline.Call your cell carrier. They may be able to help locate your phone.What to do if you can’t locate your iPhoneFinally, if you are unable to locate your iPhone, there are steps you should take to protect your data. 

The Find My app is a part of iCloud that enables you to track the locations of iPhones, iPads, Macs, Apple Watches, AirPods and AirTags. It used to be called Find My iPhone or Find My Friends, but now it is called Find My to indicate that it can be used with other Apple devices, also. The Find My app replaced Find My iPhone and Find My Friends.
A common question we often get is how accurately the Find My app shows the device or item location.It can be very critical that Find My locates your device so that you can find, lock or erase it in case your device is lost or stolen. Find My can be accessed via the app or the iCloud.com website. For this to work, you will need to turn on Find My and Location Services.

How accurate is Find My?

It depends on a lot of factors. Depending on the type of the device and other external factors, it can be very accurate or not accurate at all. For example, as you can see below, I have five devices located right here with me, but iCloud Find My shows them in different places:
Find My location mapAs you can also see, the accuracy of Find My is spotty. All five of my devices are all together and next to each other, but Find My shows two of them across the street.
With regard to the original question of the accuracy of Find My, it is difficult to provide a numeric answer.There are some scientific studies that attempted to answer this question.For example, a study done in 2009 showed that the accuracy of the location of the device within around 8 meters (around 26 feet). Two years later, another study also found similar results showing that the accuracy ranged from 5 to 8 meters (around 16 to 26 feet). was within 10 meters (around 32 feet).Of course, we can say that these studies were done a long time ago, and there are probably a lot of improvements to this technology since then.A newer study in 2019 found the accuracy was between 7-13 meters (around 22 to 42 feet).

Why does Find My sometimes show devices in the wrong place?

A lot of factors can degrade the accuracy of Find My. Find My uses a combination of GPS, Wi-Fi, Bluetooth and cell towers. The accuracy with which it can pinpoint the location depends on many factors. accuracy, such as:

Poor smartphone signalAvailability of nearby cell towersWeak GPS signals due to blockage, eg, buildings may block GPS signalsLandscape characteristics, such as trees, mountains, etc.Availability of Wi-FiAvailability of other nearby Apple devicesNearby Bluetooth devicesRadio interferenceAtmospheric conditions affecting GPSFind My is designed to work even if your device is offline or turned off.

You can check your battery health by going to Settings > Battery > Battery Health. The most important indicator there is the Maximum Capacity percentage. Mine currently says 88%, as you can see in the screenshot below. Yours may say something like 85% or 90%. The Maximum Capacity is the biggest indicator as to when you need to change your battery.Battery HealthYour battery ages but its age is not measured in calendar time like it is as we age.
What does Maximum Capacity percentage mean?Essentially, this percentage indicates how many times your iPhone has gone through recharge cycles. So what is a charge cycle? A charge cycle does not mean that you charged your iPhone from 0% to 100%.

Apple Lithium-Ion Batteryes Work in Charge Cycles. ur batterys capacity – But Not Necessarile All From One Charge. For Instance, You Might USE 75% of Your Battery’s Capace One Day, then rechage it fully overnight. If you use 25% the next day, you will have discharged aotal of 100%, and the to day add up to one charge. uld take several days to complete a cycle

Apple further says that an iPhone that has gone through 500 cycles should still retain about 80% of its original capacity. I should mention that this does not mean that after 500 charge cycles, your phone will not be usable. However, you will likely have battery problems. Your phone may slow down, or may shut itself off unexpectedly.
Apple shows how many times you have had charge cycles in percentage instead of showing the actual number. From the Maximum Capacity percentage, we cannot know for sure how many times your phone has been recharged, but we can guess.

If the number is closer to 80%, your recharge cycle is close to 500. Or, if your Maximum Capacity is at 99%, your phone has had only a few charge cycles.
When to change the batteryApple says you need a replacement if you see your Maximum Capacity around 80% or lower.
Apple may replace your battery for free if you are covered under warranty or AppleCare+. If not, Apple can replace your battery for $69 for most models:
iPhone X and later: $69iPhone SE and other models: $49You may have Apple’s limited warranty or AppleCare+.

Limited warranty: This is a year-long warranty that starts after the purchase. This is the basic warranty included with your purchase automatically. If your battery health level reaches 80% or less within a year, the warranty covers the battery replacement.AppleCare+: This can be purchased within 60 days of your iPhone purchase, or you can buy it with your new iPhone at the time of the purchase. It provides up to 3 years of coverage. You can check to see if you have an active AppleCare+ warranty.

How to replace the battery

If your peak performance is at less than 80%, there are three ways to replace the battery:
You can mail your iPhone to Apple. If you choose this option, there will be a shipping cost (in the USA, it is $6.95) regardless of warranty status. Apple usually ships back your device within 3 to 5 days.Make an appointment and take it to an Apple Store. They will probably replace it while you are there. It is usually a quick process.If you do not want to mail it or if there isn’t an Apple Store around, the third option is to take it to an Apple authorized service location. You can ask Apple about the store nearest you.I did not include the information here, but there are also do-it-yourself options. Ifixit, for example, sells battery replacement kits that you can buy to do the replacement yourself, if you think you have the right skills. You should know that this can be risky and voids any Apple warranty.
Lastly, this is a different route but, you can consider a trade-in instead of replacing the battery.

Your iPhone battery life depends on a lot of different factors. How you use your device greatly affects the battery life of your device.

It isn’t too far-fetched to consider that 24GB RAM will be the norm for smartphones in the future, and it’s thanks to AI.

Rumors have been swirling for a while now that there will be smartphones coming over the next year that’ll have a whopping 24GB of RAM. That’s a huge amount by any metric, with the most common RAM configuration on gaming PCs being a humble 16GB at the time of writing. 24GB of RAM sounds like a ludicrous amount, but, not when it comes to AI.AI is RAM-hungry

If you’re looking to run any AI model on a smartphone, the first thing you need to know is that to execute basically any model, you need a lot of RAM.
RAM is faster for a couple of reasons, but the two most important are that it’s lower latency, since it’s closer to the CPU, and it has higher bandwidth. It’s necessary to load large language models (LLM) onto RAM due to these properties, but the next question that typically follows is exactly how much RAM is used by these models.
If Vicuna-7B were to power Google Assistant on people’s devices with some help from cloud services, you would, in theory, have all the benefits of an LLM running on a device with the added benefit of collecting cloud-based data.

There’s a lot worth looking into when it comes to some LLMs currently in deployment, and one that I’ve been playing around with recently has been Vicuna-7B. It’s an LLM trained on a dataset of 7 billion parameters that can be deployed on an Android smartphone via MLC LLM, which is a universal app that aids in LLM deployment. For context, it’s rumored that GPT-4 has 1.76 trillion parameters, and GPT-3 has 175 billion.
Qualcomm and on-device AI
While tons of companies are racing to create their own large language models (and interfaces to interact with them), Qualcomm has been focusing on one key area: deployment. Cloud services that companies make use of cost millions to run the most powerful chatbots, and OpenAI’s ChatGPT is said to run the company up to $700,000 a day. Any on-device deployment that leverages the user’s resources can save a lot of money, especially if it’s widespread.

Qualcomm refers to this as “hybrid AI,” and it combines the resources of the cloud and the device to split computation where it’s most appropriate. It won’t work for everything, but if Vicuna-7B were to power Google Assistant on people’s devices with some help from cloud services, you would, in theory, have all the benefits of an LLM running on a device with the added benefit of collecting cloud-based data.
That’s just one way on-device AI gets around the cost issue that companies are facing currently, but that’s where additional hardware comes in. In the case of smartphones, Qualcomm showed off Stable Diffusion on an Android smartphone powered by the Snapdragon 8 Gen 2, which is something that a lot of current computers would actually struggle with. can test that right now.

From the above screenshot, note that I am in airplane mode with Wi-Fi switched off, and it still works very well.
Applications of on-device generative AII spoke with Karl Whealton, senior director of product management at Qualcomm, who’s responsible for CPU, DSP, benchmarking, and AI hardware. He told me all about the various applications of AI models running on Snapdragon chipsets, and he gave me an idea of ​​what may be possible on Snapdragon chipsets today. words in a sentence) that can also learn the context.
To that end, I asked him about those RAM requirements that are rumored currently, and he told me that with a language model of any kind or scale, you basically need to load it into RAM He went on to say that he would expect if an OEM were to implement something like this in a more limited RAM environment, it’s more likely that they would use a smaller, perhaps more specialized language model in a smaller segment of RAM than simply run it off of the storage of the device.
An example of a specialized use case is one that Qualcomm talked about recently at the annual Computer Vision and Pattern Recognition conference — that generative AI can act as a fitness coach for end users.

In theory, OnePlus could provide 16GB of RAM for general usage but an additional 8GB of RAM on top of that that’s only used for AI.
Of course, the other important factor in on-device AI is privacy. With these models, it’s very likely that you would be sharing parts of your personal life with them when asking questions, or even just giving AI access to your smartphone might worry people. Whealton tells me that anything that enters the SoC is highly secure and that this is “one of the reasons” doing it on-device is so important to Qualcomm.

To that end, Qualcomm also announced that it was working with Meta to enable the company’s open-source Llama 2 LLM to run on Qualcomm devices, with it scheduled to be made available to devices starting in 2024.
How 24GB of RAM may be incorporated into a smartphone

OnePlus 12 front and back on dark background Source: SmartprixWith recent leaks pointing to the forthcoming OnePlus 12 packing up to 16GB of RAM, you may wonder what happened to those 24GB of RAM rumors. The thing is that it doesn’t preclude OnePlus from including on-device AI, and there’s a reason for that.
As Whealton noted to me, when you control DRAM, there’s nothing stopping you from segmenting the RAM so that the system can’t access all of it. In theory, OnePlus could provide 16GB of RAM for general usage but an additional 8GB of RAM on top of that that’s only used for AI. even in 8GB or 12GB RAM configurations since the needs of AI won’t change.

In other words, it’s not out of the question that the OnePlus 12 will still have 24GB of RAM; it’s just that 8GB may not be traditionally accessible. ‘s an attempt at making sense of the leaks where both Digital Chat Station and OnLeaks can both be right.
Nevertheless, 24GB of RAM is a crazy amount in a smartphone, and as features like these are introduced, it’s never been more clear that smartphones are just super powerful computers that can only become more powerful.

A degraded lithium-ion batterywon’t last as long as a new one on a single charge.Here’s how to check your iPhone’s battery health.

Rechargeable lithium-ion batteries are consumables that have limited lifespans. When a battery degrades, a full charge won’t last you as long as that on a new battery. The lifespan of a lithium-ion battery has a set number of full recharging cycles. After you cross that certain number, the battery will need replacement.

Otherwise, your iPhone might become slower, shut down unexpectedly, and/or not last long enough on a single charge. Here’s how to check your iPhone’s battery health.

How to check your iPhone’s battery health

Launch the Settings app on your iPhone.
Scroll down and click on Battery.Click on Battery Health.There you will be able to find out your battery’s Maximum Capacity. If, for example, your Maximum Capacity is 75%, that indicates that a full charge now will last you as long as a new battery charged to 75% would.
Peak Performance Capability indicates whether your iPhone is being slowed down to avoid an unexpected shutdown.

When the battery is degraded, iOS limits your iPhone’s processing power. If this screen mentions that on your device, you can bypass that and restore the original iPhone speed.Optimized Battery Charging learns from your charging habits and adapts accordingly. If you charge your iPhone every night and unplug it at 6AM, for example, iPhone won’t fully charge your battery until 6AM or so. That’s because keeping your iPhone on the charger while its battery is full contributes to its degradation.

iOS will let you know when you should replace your battery by displaying a message in the Battery section. It will also indicate whether the replacement is an original battery or not. If you’re not satisfied with your iPhone’s batterylife and its Maximum Capacity has dropped significantly, you can always get the battery replaced, even if iOS hasn’t notified you yet.
How many hours does your iPhone last you on a single charge? Let us know in the comments section below.
