iOS 10 battery drain / overheating

No, my email works OK.

I suggest the next time you notice the heat and battery drain issue, that you check to see what apps are running, exit every 3rd party app and then see if the symptoms stop. This is how I came to the conclusion that my problems were caused by iOS upgrades that did not like my 3rd party apps.

As for your email problem, it may involve how your ISP set up their email servers. You may want to call their tech support.

Did you already try the usual troubleshooting steps?

Force restart the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data.

In case this does not work, and especially if you updated via Wi-Fi, set it back to factory settings, without using the latest backup. Test the phone. If it works, restore from the backup.

I'm experiencing a problem similar to Steve's on an iPad Air 2. Battery drain isn't as severe, but the iPad runs noticeably hot all the time. Started immediately after I installed iOS. Reboot doesn't help.

FWIW, I was one of the "lucky" ones who got burned by the OTA update bug during the first hour or so of availability and I had to resort to iTunes Recovery to complete the installation. Dunno if that's significant, but it seems worth mentioning.

I have an iPad Air 2 with the overheating problem. Since installing iOS 10 my battery is taking more than twice as long to recharge and it is overheating. Additionally, I am now having trouble with "fill-in" boxes. It took about 4 tries to get the curser to "stick" when I tried to log in for this comment. Now that I am commenting the screen is paging down when I backspace. This iOS 10 is full of bugs. Please put out a patch. I rely on my iPad for my photography business; its no laughing matter.

I'm facing similar issues. Battery is draining way too fast. Didn't happen with iOS 9.3.5.

I did the soft reset, have switched off background app refresh & have also switched off most of the location services. But still the battery drains. The screen is also way too bright on auto-brightness. Heating issues are there when I use apps frequently, which never used to happen previously. My battery percentage came down by 27% by only texting and browsing for 15 mins.

iOS 10 is ruining the iPhone experience. Apple please come out with a fix soon.

Sorry, but that's a really unhelpful answer. The last thing I want to do is a factory reset and then spend hours reconfiguring. I really didn't want to do the upgrade but it seemed to be the only way to get rid of the annoying on screen message popping up at inopportune times.

iphone 6S+ (Samsung chip): the battery drains fast. 20-30% for every 30min (usually browsing web/tapatalk, no game/movies). It doesnt matter what i do with it, it is always getting warm and draining fast.

doing factory reset doesnt solve anything - i have seen several people doing it and it is still the the same - the battery is draining...

Steve I have the same problem and never did on IOS 9, it has been since Tuesday or whatever day I upgraded. My phone run so hot, my contacts are slow to come up after selecting a name and batter goes from 35 to 1% in about 10 minutes with no use on it!!! I turned off the battery tracking mode and it was better! I hope they come up with a fix to this quick, my phone is my work phone and my company won't put up with this! Apple should not release new operating systems until fully tested!!!!!

I did the factory reset and set up the phone from the back up, turned off all my locations services and app refesh and I swear it is worse! A waste of two hours and the Apple Support agent told me it was normal! No way buddy!!!! I have had an iPhone for about 9 years and never had it run hot constantly and drain my battery so fast with barely any use! The guy must thought I was clueless to feed me that BS! Bottom Line, don't waste your time!

And why would I possibly need to do all that (which other posts indicate does not one iota of difference) after a simple upgrade of an OS system. Why should I do somesaults, backflips and other forms of electronic gymnastics to compensate for a bug laced update?. Why do I need, as some would suggest elsewhere, need to go and turn off a whole multitude of toggles on my iphone on ios 10 (which I did to no observable effect) when everything was working just fine on ios 9?. What is this nonsense? Why don't we get some intelligent response from Apple instead of the "see no evil/hear no evil, I-am-sitting-on-my-hands treatment?

Mine did that the first day - down to 30% by mid- morning... I avoided the initial download bug, and did it via iTunes. That said, after a day or so of being a bit hot, and really low on power, the iPhone has resorted to it's original battery life... in fact it seems pretty good. I read somewhere the Phone is indexing all my pics and doing all sorts of background stuff... plus you may be trying out all the new features more than normal.

My suggestion is give it a day or so... then back-up using iTunes and restore.

Hope it's just initial settling down you're experiencing.

Best.

Dunno if this will help others, but I think I have identified the source of my own overheating problem.

After upgrading to iOS 10 I noticed that one of my notification widgets was wonky -- a large but empty reserved area with only the app name at the top. I didn't really give it a second thought, figuring that an iOS 10 compatibility update to the app would probably be forthcoming.

After first revoking all background refresh capabilities to no avail and killing all "legacy" apps in the task manager to no avail, I set about killing the most recently (and most often) used apps one by one and monitoring the device's temperature after each app got the axe. Sure enough, after I killed the app associated with the wonky widget the temperature dropped. I disabled the widget, rebooted, and restarted the app without installing the widget. The overheating problem has ceased and battery life is back to normal.

I shouldn't think a runaway app or widget could have this effect, but such appears to be the case. I'll be interested to see if the problem persists when the widget is installed after the app is next updated.

Actually a "stuck" app or (now) widget is a common cause of this behavior after and update. Nice detective work!

I have a new iPad Pro and I am using ISO 10. My I pad pro is discharging very quickly with this new software update, please fix ASAP

I Am having this problem too. Doesn't take an hour to drain the battery from 100 to 20, this is a major problem and hope there will soon be a fix for this.
