I had no issues with iOS 6 on my iPhone 5 nor with the iPhone itself.

This morning, I installed iOS 6.0.1 and since then my iPhone has been staying quite warm and the battery has been draining about 20% per hour (that's 20% of the total charge capacity). This heat and battery drain occurs even with no apps running after a fresh reboot of the iPhone.

 

Does anyone else have suggestion regarding what might be done to prevent the iPhone from using up the battery? Or, is this just a new problem introduced with iOS 6.0.1?

 

Thanks,

 

Ben


iPhone 5, iOS 6.0.1

    Same here.  After the 6.0.1 update both my iPhone 5 & my wife's battery is draining fast.

    Same here too. My iPhone 4 drains a completely full battery in a little about 4 hours, and all since I've installed iOS 6.0.1 yesterday. Before with 6.0 everything was fine.

    Same here. But it is quite strange...

     

    My devices:

    IPad and IPhone, both 6.0.1 are getting warm from time to time, battery draining... temporary fix: activate airplane mode...

     

    My wife:

    Iphone and Ipad, both 6.0, Iphone is getting warm, battery draining... IPad behaves normally!!

     

    What I tried and can rule out:

    EMail from push to manually pull --> doesn't help

    ICloud Documents and data change -->doesn't help

    Location services deactivated --> doesn't help

    Sending Apple debug information deactivated --> doesn't help

     

    For me, the worst ist not the battery drain.... The reason for the warm device seems to be, the device sending data via cellular.. I had about 1GB traffic in 2 days!

     

    I almost suspect some app to be the reason. My wife is quite slow when it come to updating apps. So her IPad has quite some updates left.

     

    At the moment, I have deactivated Photo Streams. Let's see, if this helps.

     

    Really strange.....

    Anything in your "Diagnostic and Usage" logs to help you identify the issue? I saw an improvement in my battery life.

     

    For me iOS 6 was worse for my battery life, when I first activated the full feature set (Push Email, iCloud, Notifications etc) my phone was hot to touch and it turned out to be my email "Exchange" calendar and a rogue app trying to constantly update to iCloud.

     

    I hazard a guess that Apple's update to iOS 6.0.1 may have caused some latent app issue? Have fun trying to find it.

    I am seeing dataaccessd errors in the Diagnostics & Usage tab.  Not sure what is causing it.

     

    I turned Settings > General > Cellular > Cellular Data to 'off' - that seems to have stopped it from getting hot and draining the battery too quickly...

    1. Reset iPhone (no data loss):  Press both home and power buttons for at least 10 seconds, releasing when the Apple logo appears.

     

    2. Restore phone in iTunes using a backup.

     

    3. Restore in iTunes as new, without using a backup.

    Im having the same issue. Phone gets very warm and battery drains very very fast.

    I tried reset network settings.

    I tried reset all settings.

    I'm now doing a full restore.

     

    New phone cost a lot of $$

     

    I had a similiar problem when I had the 4S, ended up taking it back and getting a refurb. I find the whole return process very disappointing, you buy an expensive new phone and end up with a rebuilt used phone and hope it works.

     

    For a Co that rakes in BILLIONS$$ every quarter I find that return policy very very disappointing. If I dont get satisfaction this time round this will be my last iphone.

     

    I thought Apple was a Co that had its stuff together. Not true and they never admit there are issues. its always deny, defend, blame the user, blame some other app, blame the networks.

     

    Sad

    David, one of you email accounts is an Exchange Activesync one?

     

    http://support.apple.com/kb/HT2480

     

    If so I would try the following to see if it resolves your issue:

    1) Turn "Wi Fi" Off whenever you leave your "Wi Fi" zone.

     

    If the above doesn't work then or you don't want to do that:

    2) Goto Settings > Mail, Contacts, Calenders > Select your "Exchange Activesync" account and remove from your iPhone. Re-add again to see if this resolves your battery issue.

     

    If the above doesn't work then:

    3) Goto Settings > Mail, Contacts, Calenders > Fetch New Data > Select Every 15 min/ 30 min or Hourly, Then Goto Advanced > Select your "Exchange Activesync" account and select Fetch (Manual is another option).

     

    If the above doesn't work then (Warning: The below option will cause you to re-configure your whole phone again):

    3) Goto Settings > General > Reset > Reset All Settings and try 1) / 2) /3) again.

     

     

    Failing that it maybe worth talking your "Exchange Server Admin" at work about the below settings:

    Yes having that problem also started directly after updating

  • David Graham2 Level 1 (0 points)

    I don't have an exchange account.

     

    Unfortunately I need to retract the statement that turning off cellular data 'did the trick' too.  It slowed it, but not by much...

  • Araknd Level 1 (30 points)

    I noticed this also on my iPhone 4.  IOS 6.0 actually gave me more battery life and then 6.0.1 took it all away and the battery seems to be draining much faster now.  ***!???

    Other source of this can be the Calender from google mail. Same tips apply if you do have that Google mail.

    Then tried that, nope.

    DING DING DING!!!  This did it!  Pain in the butt, but it works...

     

    Thanks!
