Q: iOS 10 battery drain / overheating

I Updated my iPhone 6 64gb to iOS 10 yesterday, today with normal low usage my battery (charged every night) has dropped from 100% to 38% in just over 1 hour   I've also noticed that in use it is getting very hot something it never did under iOS 9, so apart from the positive of now having a winter pocket hand warmer it will be a useless phone after mid day   I hope iOS 10.0.2 comes out quickly to address this issue, a very disappointed Mac user since Mac OS 8.5

    Brilliant! This resolved the issue of battery drain and overheating immediatley after reading it. My Phillips Hue widget has been greyed out and unusable since updating to 10. I deleted the widget, restarted the iPad, and no more overheating and battery drain. Thanks!

    My wife's phone has been suffering this bug for the last week after updating to iOS 10, and I've been trouble shooting since then.  I just discovered that it has NOTHING to do with the battery, and i priced this playing a movie over and over for 4 hours. The difference was toggling airplane mode.

     

    after the test, i was curious how the iPhone 6s would behave if i turned airplane mode off and it immediately shut down and was stuck in the plugin prompt screen.

     

    At this point i tried to isolate exactly what comm in airplane mode was the culprit, and it seems to be Wi-Fi. The phone is currently running the movie test again with only Wi-Fi disabled at its performing flawlessly.

     

    I anyone else is having this issue, please test first with airplane mode and, if it makes a difference, to isolate what comm feature is causing the glitch. I'm very interested in the results.

    I tried to reproduce this issue but without luck. On my phone the battery drain is the same with or without wifi enabled.

    In the last days I have performed some factory resets without importing the backup.

    The battery drain is the same as before but the overheating issue seems to be away.

    Maybe it is a behaviour with the new installed iOS 10, if I have some luck it is away before Christmas...

    I will wait additional three days and then I will have a look at a new phone...

    t thanks for the response, but sorry to hear turning Wi-Fi of didn't work for you. I've been doing more testing and tried sexual things that have allowed me to resume using Wi-Fi in my wife's iPhone without draining the battery.

     

    I removed all widgets, uninstalled Facebook, Facebook messenger, turned off background app refresh on every installed app.  Since then, I've reinstalled Facebook and messenger without problem.  It's looking like one of the apps is going crazy in the background, but i haven't yet isolated which one. Just happy to have a functional phone again.

    be aware with Facebook and Messenger Apps,

    control it with your desktop computer, not just one time, but several days.

     

    it just happened with me, they were off on iOS, and from a desktop open the Facebook with a friend account and was possible to see that Facebook says that you are available per Phone. if it is so, means your iOS App even off is communication with the Facebook servers. on the Battery monitor I was never able to see it, just with a friend Facebook desktop.

     

    this tip was published per many bloggers in the beginning of this year, iclarified, 9to5mac .....

    This IOS 10 is just plainly troublesome as it causes too many overheating + battery drainage problems without any use of the updates. I have soft reset my Iphone 6S 4x and even did a factory reset just to try to overcome those issues, with NO avail. I just want my phone to go back to how it was before the update. Please do something about this, Apple. -Don't release an IOS that isn't ready!

    Battery issue solved.

     

    I updated the phone to iOS 10.0.2 & did a Network Reset, charged the phone to 100% & there were no issues after that.

     

    Battery is now lasting full 24 hours on normal usage (browsing about 45 mins, texting, Facebook & Twitter - 20 mins, gaming - 20 mins & mailing). My iPhone 6 was 100% at 9:30 AM. Went to work and was on 3G/LTE till about 7:30 PM. Was texting & checking emails at work. The battery % was 63% when I came home. After browsing, social media & playing a game the % dropped to 38% by the time I went to bed. The % dropped only 2% overnight to 36% & by the time I put the phone to charge it was 30%. So a good 24 hours of backup or normal usage. I use Facebook & Twitter only on WiFi.

     

    A lot of complains of battery drain were regarding to the Facebook app. Hopefully they've sorted it out.

     

    There is still a heating issue when using the phone while, updating of the apps is going on in the background but I think this is normal.

     

    So I think a Network Reset does the trick & iOS 10.0.2 has solved the massive battery drain.

    I will not say that everything is fine just with the Network reset, but no doubts that is the step to do for the biggest improvement. Here lies also the Phone providers, have they updated their software accordently? answers that most of us will never know

     

    Apple and all the Developers have work around to do in order to improve overall the Battery life. Before I published that the problem was solved for me, overall I would say yes, no more battery heating, the battery lasts for about 26h with about 3,5h of real use. but yesterday happened again a strange situation, I was by 22% when wake-up, played my rotine game about 10min, and then the battery was still 22%!!! I told to myself cannot be, turn off the iPhone (just turn off, no reset), turned on again and supprise, the battery was by 35%!!! strange!!! and kicking *** using forward untill was under 10%, then I re-charged again.

    Exactly the same issue after 'upgrading' to iOS 10.0.2, Iphone 6 goes down at a rate of 10 to 15% every hour, with almost no usage. Never had the problem before the latest OS.

    I turned absolutely everything non-essential off, all what was on during the 9 version with no issues whatsoever. Not sure yet what was the point in upgrading. Runs down rapidly to 40 or 50% and all of a sudden showing low battery. If I am on a call it simply dies. On plugging into power source it goes back up to the previous level. Should not be the Wifi though, as it also happens without.

    I can only hope for a new update soon to fix this. I guess my own fault to upgrade.....

    Restored to iOS 9.3.5 via iTunes today, same issue. So i think I have a hardware problem.

    Talked to Apple, ran diagnostics and they offered me a free repair. So maybe just coincidence and not iOS 10.

    Please try disabling the background app refresh for ALL apps and see if that helps.  You can do that by going into settings and simply scrolling down until you see the apps, going into each one, and disabling background app refresh for each one.

    So, I thought that the 10.0.2 might have fixed my problem, but it came right back to the point that I had a full charge at 10pm, I watched 20 minutes of Netflix, went to sleep, and woke up with a dead iPad.

     

    So a couple of days ago I did a complete restore. So far, so good. Running normally.

    Both, my wife's and my iphones started to overheat and run out of battery much quicker than with iOS 9. Can no longer unlock the phone by swiping to the left. This update really *****.
