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

    Even when I decided to update it, my phone went from 75% before the update to 20% after. It shouldn't take up that much of your battery.

    Disabling all the widgets certainly seem to help. I think the issue is primarily to do with weak signal. The way the weak signals were handled seems to have changed with iOS 10 which is resulting in the battery drain. It seems to have impacted my iPhone 5 but not my iPhone 6. However, my colleague with an iPhone 6 had the issue and so I am not a 100% certain of the root cause.

    I have unplugged my phone 20 minutes ago. I´m in airplane mode, battery savings mode, no widgets enabled, gps disabled, all apps closed, disabled background app refresh and just WiFi and I´m now on 90 per cent.

    So I think the root cause isn´t the signal handling. I also have an iPad Air with the same carrier and this one isn´t affected by this issue.

    Next time I will wait two weeks or more before installing a new release...

    If you just installed it yesterday it might just be new indexing occurring for the new photo services and such during the first day or two.

     

    Wait and see if it gets better.

     

    I had the new OS for more than a week now but still have the same problem so there is something fishy going on. Really hope they'll fix this with iOS 10.1 soon.

    Same issue on my new iPhone 7, i have turned off location services, messed with widgets.  I am down 25% in an hour with it sitting on standby.  So frustrated.

    I've been having the same problem with my 5s, if I use it for about 30 or so minutes it heats up like crazy and the battery life has decreased a lot. I use my phone early in the morning and the battery goes to 100% to 60% in an hour, then by the end of the day (when I don't use it much and leave it on) I'm left with 30% or 40%. I leave low power mode on all day too and it's still like this. They need to send out a fix for this so we don't have to charge our phones so much and so I don't have to turn on airplane mode because I want to see my twitter nonifs and messages.

    I had this problem, and tried literally EVERYTHING to resolve.  FINALLY, just when I was about to give up after days of trying - I found my problem.

     

    On the email app, I had iCLOUD account established with username but never provided a log in password.  Apparently, the ipone was constantly trying to log into iCLOUD email with no success.  I don't use the iCLOUD email - so I deleted the profile and it immediately resolved my iphone overheating and fast battery drain problem..

     

    Hope this helps you as well.

    Unfortunately, that didn't solve the problem for me. iPad mini 4 here with the same overheating issue that everyone else is reporting.

     

    I ran the public betas with no issue, only started seeing this issue once the final release was out.

    i was having iMessage issues before all this happened.  Did anyone else experience iMessage issues?  i am trying to enable iMessage on my iPad mini without success now.  After reading other replies I'm thinking maybe this is an icloud issue???  Having issues getting my Apple ID to be recognized on my iPad mini when I disabled iMessage and enabled it again.

    i don't understand why no one from apple is responding.  Having to keep my phone plugged in defeats the purpose of having a mobile phone.

    Thank you for the idea. I got the default iCloud account for find my iphone and stuff.

    It did not ask for the password but i signed out from icloud and the overheating stopped. I reenabled some things now and the battery drain is a little bit better (have used it for an hour and it is now on 53%). I will charge it this night and will give a response.

    My iCloud is already switched off but still the battery drains. I've even switched off the iMessage. What's the point in switching off these apps and updating the software ?? Apple should have figured it out before releasing the update.

     

    In iOS 9.3.5 on a normal working, day my battery used to last a good 22-23 hours, on normal usage & playing a few games on Wi-Fi. I barely get 15 hours now after the iOS 10 update. Battery drain is massive on 3G/LTE usage. It wasn't like this before. Hopefully with the release of 10.1 beta we will get to see a fix soon.

    I have iPhone 6s - iOS 10.0.1 and a couple of times turns off at around 30% of the battery level 

    this situation occured me in the past also with my iPhone 5s and the iOS 9. at the time the Genius Bar checed the batery life and was fully on the green area, and they advice me to do a reste from the Network Configuration, only to the Network. I did it, cost me maybe around 1 hour and solve it. Today evening I will do it to my 6s and I will post the results later.

     

    out of curiosity, with the Battery information on the configurations, we can see exaclty how much time we used the last 24h. I my case sum it up to 3.2 hours using the iPhone duriing the last 24 hours. One charge (when goes completly off at 30%) last about 12h to 13h, against the 24h to 26h with the iOS 9. Lets say 50% of the battery live is gone with the new iOS 10.

    Unfortunately, I have the same problem on 6S+128. The funny thing is that there was no problem on last Beta. On the battery settings I see problem with App store background utility- this is what drains battery.  For now no solution helps...

    I have an iPhone 6 (64GB).  Updated to IOS 10 four days ago.  Same problem with battery drain and overheating.  Have tried everything suggested and the only thing that makes a difference is to put the battery in low power mode.   Was sad to see a few iPhone 7 users with the same problem because I was considering an upgrade, but not now.  What is the point of having cool features on a phone when you can't use them without draining the battery or overheating the phone ?

    Hope Apple will look into this.
