    I was having terrible battery issues.  I am not using exchange, however was using hotmail and gmail.  I deleted these accounts from my phone, did a phone restart and then reinstalled the hotmail account.  Haven't installed my gmail account back yet.  Battery life seems to be better now.  I haven been at 100% for the last 20-30 minutes.  I haven't used it a bunch but some.  I'm hoping this may help or fix the issue.  Just thought I would pass along in case it helps any others.  Is very frustrating having to charge your phone every 2-3 hours.

    You need to "sort it out". There's an app on your phone that is stuck in a loop sending data or attempting to send and failing. This is a common problem, and is not unique to any particular version of iOS; battery drain has been observed with every version back to 1.0 (see https://discussions.apple.com/thread/4824373#21302699. )


    You can fix it by identifying the app. Mail is a common offender. If you have an Exchange email account or an iCloud account go into Settings and turn it off. Then reboot the phone by holding the HOME and SLEEP buttons until an Apple logo appears. After the phone comes back on (about a minute) turn the accounts back on. Facebook is another heavy battery user. Kill it in the Quick Launch ribbon, along with any other apps that can receive notifications or run in background.


    If all else fails restore the phone using iTunes and set up as a new phone. You will probably note that the battery drain is gone. You can restore your backup then. If the problem comes back you have data corruption in your backup.


    Another step that sometimes resolves the problem is to run the battery down until the phone shuts off (which kills all processes running on the phone), then charge for 4 hours with the wall charger.

    I would tend to agree with you Lawrence, however it must be a iOS bug.  My phone was working perfectly fine until the iOS update.  After the update, immediately my phone battery was terrible.  I have ran the phone dead, restarted, turned apps on/off, etc.  However everything running is the exact same that it has been since I got my phone new in October.  No issues with anything until the iOS update and I haven't installed any programs after the iOS update 6.1.1 and been having troubles since. 


    The latest thing I tried, and I am not using exchange, is to delete my email accounts on my phone and reinstall.  That appeared to have maybe helped.  I used to be able to run my phone for a full day or two before a charge.  Now I have to plug it in every 2-3 hours since the iOS update.

    The problem is there are messages almost identical to yours in the forum over the past 5 years, except you can substitute any iOS version for the one you are referencing. So you will find people convinced it is a bug in 5.1 because when they updated the problem started, or 3.1.3, or 2.2.1. For you it was 6.1.1, I gather.


    The only thing in common is that the problem started after an update; it doesn't matter what the update target was. So the logical conclusion is that updating the phone causes the problem, not the version you update to. I don't know why this happens; my guess is that the update process interrupts some app doing something, then the app tries to resume after the update but doesn't start in the right place. The other observation is that it is a rare occurrence. I didn't have any problems with battery life after updating, and I would guess that out of 400 million iOS devices the overwhelming majority had no problem. When a large number DO have problems you will see several thousand posts in the first few hours. The record is currently 15,000 posts and 1.5 million views for a real problem with 6.0, that was fixed rather quickly. I DID have a problem after updating to 3.1.3 several years ago. And my first though was it's a defect in the release. It wasn't, however; it was a corrupt calendar entry that the phone kept trying to update and failed over and over.


    You will also observe that people regularly report a sudden battery drain out of the blue, not associated with any recent update. So it's also possible that it is a coincidence, that the problem would have occurred whether you updated or not, but, since you just updated it appeared to be related to the update. With 400 million devices there will be coincidences.

    Darned !!!  iOS 6.1 and 6.1.1 fixed what had been a terrible battery drain situation. So I assumed that 6.1.2 would not be a problem. But woe be unto me. After the 6.1.2 update my phone is draining like it has a hole in it. I did all the usual attempts to fix-- resetting network settings, power down and restart, turning off all push e-mail, etc. On wifi I'm losing about 10% every 30 minutes...on track for about 5 hours battery life and nowhere close to Apple's advertised 8-9 hours on wifi. Under 6.1 and 6.1.1 I was easily getting around 8 hours or more. Boy do I wish I could go back to iOS 5.1 when I routinely got 9-10 hours of wifi use.

    Worst Update of my life.  Never seen such an aweful battery drain since I updated to iOS 6.1.2 last night. I have recharged my phone 3 times in the space of 6 hours...

    i really dont know whats happening on my iphone 4s after updating to 6.1.1... Battery Headaches Persist... yesterday installed 6.1.2 using itunes and set my phone as new.... i just turned off location services, icloud, notifications, wifi, bluetooth, 3g, mobile data, etc. i didnt restore my old settings. but I'm losing about 10% every 30 minutes.


    another thing is, since i got this phone im losing my 2g network and reboot fixed the problem. i always have to reboot my phone. turning off/on airplane mode didnt work. my network provider changed my sim 3 times. i dont know if it is software or hardware issue. the problem is the signal didnt come back. i have to restart my phone.

    After this update ios 6.1.2, the battery lasts approximately 3~4 hours only. Wish there was a good option to roll back.

    It's good to wait for few more days till Apple and MS come to a common, stable and optimum solution for this issue instead of rushing for the updates and bringing the fone to a worse state.
