    DO NOT restore or do anything drastic!!!!!



    ALL you need to do is:


    Settings> mail contacts calendars> Fetch new data/Push> turn Push OFF and set to manually or hourly


    Fetching new data for you mail DRAINS your battery like crazy

    I had tried that - didn't work for either me or my wife.

    Have you also tried going into settings>notifications> and turning push off on all of your apps (especially Facebook)

    A restore from your back up is not drastic, But to addres the issue and from the info i have and my own settings on my iphone 5 , Turning off everything in icloud except contacts, after i have down a icloud backup ( which i do do regularly and an itunes backup regularly )  has improved my battery life 10 fold.

    I have still no clue, what could possibly the reason.

    I think, I have disabled, all I culd (Notifications, Icloud, Push, Location services,sending diagnostic data (which did not show anything up to date or useful)), but the problem still occurs...


    Pad/Phone is getting warm in unpredictable intervalls (because of generating lots of traffic), battery draining (then) like 20% per hour.


    For the Phone, resetting it to factory without using the backup seems to have worked. Interesting how much space you gain from not installing "useless" apps you have not used for a very long time...


    For my IPad, I am still not sure, how to proceed. It is getting so warm, and the battery is of course draining slower, but I don't like the situation at the moment...

    I thought this was the solution until today where I put something into the calendar, this started of the battery drain again... Could access any Exchange server emails either, no crash logs. Something isn't right with iOS 6.0.1..... Had to move the calendar input into my iCloud calendar to stop the drain..


    In the mean time my iPad 3 on iOS 5.1.1 is working perfectly fine with max settings.... Not upgrading my iPad till this issue is resolved..

    Hi Friend,


    Try: Settings >> General >> Reset >> Reset All Settings. I had an overheating, battery-draining iPhone 5 yesterday, and the reset seems to have fixed that. Battery life was reasonable today, and the back of the phone was no longer hot.


    A restore would probably also work, but a reset takes much less time


    Hope it will be helpful

    I am on the Verizon network using the iPhone 5. I saw the same battery drain, albeit not as bad. I will try these steps as I also have an Exchange Account and report back for each trouble shoot if it worked.

  • Araknd Level 1 Level 1

    I have an iPhone 4 on Verizon, but no Exchange connection and the battery drain continues.  In my opinion, since there are many users of different configuration iPhones on different carriers, the problem is systemic to the IOS update.  Apple needs to find the root cause and FIX IT!!!!

    Ive been travelling last couple days so could work on the issue with my phone. Had to keep it on airplane mode mostly.

    I found turning off LTE made the phone run a little cooler and battery last a little longer. But sucked not having a fully usable phone on a business trip.


    I just tried deleting and re-adding my Exchange account. turned off wifi and turned on LTE.


    We'll see how it goes...........

  • Player8 Level 1 Level 1

    My whole exchange account was out of service on iOS6.0.1 yesterday (server crash at work), when I made a calendar input the phone there was no response from the server... My phone was hot and seemed to be constantly trying to get confirmation from the (crashed) server, really no fix for this other than putting my input into a non Exchange Calendar as my Exchange account is already on a manual setting already.


    No issues today as the server is working fine.

    Agree Apple need to sort all the various battery draining issues. How bad is yours draining at the moment?

  • Araknd Level 1 Level 1

    Well, after endless reading of messages and not seeing any real solution, I did a complete reset of the iPhone and moved the synchronization from my now dead Win7 desktop machine to my MBP 15".  What a hassle!  It seems like the drain is slower but still draining in a perceptible manner.  More later.

  • Level 1 Level 1

    Today my iPhone was back to normal. No heat. Not rapid battery drain.

    The last step I tried was deleting and re adding my exchange account.

    Don't know for sure if that step was all that was needed to fix because I did resets and restores and full cycle charging before.

    Anyway good luck to others.
