Is it possible to write an iOS app that displays the battery percentage of an associated Apple Watch? It seems like it should be possible because the Battery widget supplied by Apple does that. But I haven't been able to find an API for getting that information.

We're working on a graphics-intensive game for iOS, and we are very concerned about battery drain and thermals. While it's hard to control the user's conditions (ambient temperature, insulating case, battery lifecycle, etc.), we know we can't ignore these issues and we want to make sure we're in line with general expectations. We have found it very challenging to get consistent measurements for the different thermal conditions, such as how long it takes to reach T2 from T1. Room temperature has huge effects. So, we thought a more consistent metric may be battery drain: how much % is used after 15 minutes of play, for example? If we were to focus on this as our metric, would this also take care of heat generation? Specifically, if we make a change and do an A/B test, and found that battery drain was the same, can we safely infer that our heat behavior is also the same? Or, if we did another AB test and found that it drained the battery faster, can we assume the change would also increase phone temperature faster? We have of course observed oddness with the battery percentage, but with some caveats in mind, it seems like something we can measure much more easily and consistently. Any insights in this would be much appreciated!

somente eu q estou tendo problemas com a nota atualizaçao? tenho um iphone 11 ele do nada para de carregar comprei fonte nova e carregador mais continua, so começou depois dessa nova atualizaçao

My iphone 11 battery health decreased by 1% in 3 days, i do not think this is normal please anwser me :/

The recent uptade (Beta 5 iOS16) of showing battery percentage is not available on the Xr and 11 models. But it doesn't make sense, the X and XS have it. Will it be implemented in the next versions?

So how can a company lunching a new feature which is the 120 hertz screen which enables people to play 90 fps on games and then they limiting this feature due to battery saving plans ? Like people is paying $1200 buying the phone to enjoy the smoothness of the fps and then apple limit this feature there are too many people who is damaged from this problem and looking for a solution so can you please let me know what’s going on? You might be only an advisor but can you like connect me to a developer or something . It is just lagging to much like is it literally 40 fps i have connected my phone to the computer using an app to measure the fps so when i use guided access it is only 40 fps so much lag cant even play when i disable guided access it is a steady 78 fps with fake damage which means fake fps but before everything was nice and clean can you fix the problem

Hi I'm asking about my iPhone. So Im the second owner of the phone and It still under warranty till 2024. So when I go to the nearest Apple store and said I want to replace my battery. They said okay but then they charged me for it. But when I searched online it says "if it's still under warranty then the replacement is free"

Hi, what is the best way to handle dark mode for third party web content in WKWebView?

Build the ability to airdrop or “Apple pay” type of technology but to share battery life. Use case: I was recently at a sporting event with my daughter and needed to leave her there and I didn’t have a charger to give her. Her phone was at 11% and mine at 76% I wish I couldn’t texted her some of my battery power or tapped my phone to hers and approve a battery life transfer. Sending this thought to others who would know better how to make that a reality.

My unity game is getting very hot quickly, So I use XCode Energy Impact to test the energy use for it on iPhone8. In Debugging Gauges, Click Energy impact, I can get the following data: CPU for 45%, Network for 10%, Overhead for 45%, Location for 0%, GPU for 0%. Location is OK because I don't use it. But Why GPU is 0%? Click FPS, My game run for FPS 60. CPU cost 16.6ms, GPU cost 5.2ms. I want to compare the energy consumption of CPU and GPU, but 0% for GPU is obvious wrong, how to fix it and get correct data? And, I can't find Energy Log or Energy diagnostics in Instruments, How can I find and use it?

My friend is facing an issue of Battery capacity declining. He is not a nerd, but I am trying to helping him out. In coconutbattery its showing 98.4% maximum capacity over hardly 10 cycles while in system report it shows 100% capacity. Please answers if you have researched or have find some solutions. Is coconut battery accurate than system report? Is it good if macbook get charged all the time? (to reduce cycle) the USB-C monitor charges the macbook slowly means the battery get reduce very slow. is it a good practice? I have heard if your battery reach 80% capacity before the warrenty expires, you will get free battery replacement. is it true in India? Even after at 80% capacity, how many hours we can use the laptop? No need to answer all the questions. Please use sequence number Here I am attaching 2 images of coconutbatter report and system battery report

After Energy Saver mobileconfig file with Display sleep time as 1 and System Sleep time as 2 successfully, and then when you change the settings in System Preference->Energy Saver manually. The time that was set manually takes effect instead of what MDM has set for MacBook Pro(Intel Chip tried in both Sierra as well as Monterey). Please find the mobileconfig that we tried below. <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict>     <key>PayloadContent</key>     <array>         <dict>             <key>PayloadDisplayName</key>             <string>Energy Saver</string>             <key>PayloadIdentifier</key>             <string>com.286E9EC9-588D-4BDC-B90C-F4FBAC58A2F0.com.apple.MCX.24D336A4-FE03-493F-81B6-C4CEB640F58F</string>             <key>PayloadType</key>             <string>com.apple.MCX</string>             <key>PayloadUUID</key>             <string>24D336A4-FE03-493F-81B6-C4CEB640F58F</string>             <key>PayloadVersion</key>             <integer>1</integer>             <key>com.apple.EnergySaver.portable.ACPower</key>             <dict>                 <key>Disk Sleep Timer</key>                 <integer>5</integer>                 <key>Display Sleep Timer</key>                 <integer>1</integer>                 <key>System Sleep Timer</key>                 <integer>2</integer>             </dict>             <key>com.apple.EnergySaver.portable.BatteryPower</key>             <dict>                 <key>Disk Sleep Timer</key>                 <integer>5</integer>                 <key>Display Sleep Timer</key>                 <integer>1</integer>                 <key>System Sleep Timer</key>                 <integer>2</integer>             </dict>         </dict>     </array>     <key>PayloadDisplayName</key>     <string>Energy Saver</string>     <key>PayloadIdentifier</key>     <string>A5406D19-83C6-45B2-B6D2-EF9AF9D59EA8</string>     <key>PayloadRemovalDisallowed</key>     <false/>     <key>PayloadType</key>     <string>Configuration</string>     <key>PayloadUUID</key>     <string>803ABA57-F75B-42EB-9849-15D7EAE7B7FA</string>     <key>PayloadVersion</key>     <integer>1</integer> </dict> </plist>

Hi I was using android for a long period of time however now am using iphone its newone one and its security, camera and others are good enough but the major problem of iphone is battefy especially when i use camera, phone call and wifi. Android is excellent in battery. So what do you think can you make some improvements while updating to ios 15.6 or somethig. Hope you will have some goodnews thank you.

Hello since updating to 12.3 beta it seems the battery charging has gone haywire. the battery doesn’t charge consistently now and also it sometimes discharges while connected to power?! has any one else experienced this? im on a MacBook Pro 16inch 2020 version

Hello, my Macbook Pro (MacOS Mojave version 10.14.6) shuts down randomly when it still has battery, but says it doesn't have battery left. Then when I plug it, shows that it does have battery, which is very odd. I looked into the terminal, with the command: log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 24h to see which was the cause, and it appears:  Previous shutdown cause: -11 but I can't find anywhere what this means, does anyone know the meaning of -11? thank you.

As title. I just upgraded my iPhone 12 Pro Max to iOS 15.4 Developer Beta 1 from iOS 15.3. Previously, the "Find My network" option was visible in the bluetooth setting for my AirPods Pro. However, after upgrading, this option is missing. Is it a bug or is that something Apple intends to do in the future. I do NOT want to enable this feature because it drains the battery on my AirPods Pro.

I have the task to add the battery health in app. I searched for a couple of hours and did not find a specific answer whether this is possible in iOS 14 - 15. I found objective-c methods to get this information however they are marked as depricated. Thanks for any help.

At the moment, I determine the start time of charging, the percentage of the start of charging and, based on these data, I try to calculate the time until the end of charging. However, the problem is that the values ​​that come from UIDevice.current.batteryLevel don't quite match. Since their accuracy is .00 and this way I can only get data from 1% change. Question Is there any other way to determine the time until the end of charging, or a way to increase the accuracy of reading the charge level? Thanks in advance for your help.
