    Try changing email setting from push to fetch on all your accounts except maybe the primary one. This works significantly increasing battery.

    I knew I shouldn’t of upgraded the bloody iOS, I’ve had 5.0.1 with the battery life lasting the whole day (morning till night) with a normal use of everything (games, apps, browsing) NOW that ios 6 is out I thought what the ****, I’ll try it out. OOOHHH at what point did I upgrade!! I immediately regretted that decision. Upgraded to ios 6.1 battery life draining faster than before, waited for ios 6.1.2, upgraded ooooohhh why why did I have to do it, now I can practically see my battery drain as im using it, a 1% every minute o so on. So from 100% batt its last around 5 hours till it goes 0.


    I’m probably wasting my time here as Apple doest actually care about us, the battery is a very important feature in these new smartphones and especially if Apple claims that their iDevices are the best and no others are as good enough.

    Well I got news for you Apple (TIM pay attention), if you do not look after your Users they will just go and buy an Android Phone and start supporting Samsung, Do you really want that Apple? Really really? After all the court cases you´re having with Samsung, do you really want us to go and buy Samsung products? Just because you can’t be bothered to fix a F***ing stupid issue like the battery?


    I don’t want to go and buy a Samsung Galaxy phone nor a HTC thingy and less do I want to start using Android, BUUUUUT if you do not start looking after us we will stop buying & using your products just because all your interested in is the $$$$$.

    So please do yourself a favour and make Steve Jobs proud and do something about it!!!

    Check out my post for more info:


    I'll keep it updated with a list of solutions.

    What's interesting to me about your post is that it's the same method that has worked to resolve sudden battery drain with every version of iOS over the past 5 years.


    Which means there's nothing special about 6.1.2. This is very old news.

    On my iphone 4 before 6.1.2 I had the best battery I've ever had. Now, after 6.1.2 it's draing like crazy. The fix ruined my phone.

    Well, you can moan about it, or you can read the thread you posted to for information on how other people have solved the problem rather simply.


    The choice is yours.

    Well, before I MOANED, I should have stated that I had tried the aforementioned solutions with no success. Any other ideas Larry?

    Well, first, get out of your head that this is specifically a 6.1.2 issue. The identical issue has been reported after every update of iOS going back to 2.0. And it doesn't affect all that many phones with any specific version, but if it affects yours that is no consolation.


    The cause, with other versions, and most likely 6.1.2, is an app that got stuck in a loop sending data or trying to send data and failing. This can happen at any time, but appears to be more common after an update. It isn't ONLY after updates, but the other reported instances are scattered in time, so they don't stand out in the forum.


    With 6.1.1 it was caused specifically by a problem with Exchange calendar syncing. I gather this did not affect you, but it did affect a lot of others, which is why 6.1.2 was rushed out with less testing than usual. Even this was the same cause; it's just that the reason Mail was resending was because the calendar database was corrupted.


    The way to solve it is to identify the app. Mail is the most common offender, probably because email format standards are rather loose, and minor corruption in an email (or contact, calendar, or note) envelope will confuse any mail client. So the first step is to turn off your email accounts in Settings, especially Exchange, Yahoo, Hotmail and iCloud, then reboot the phone. While the accounts are still off, see if the issue is resolved. If it is, turn the accounts back on, and wait a few hours before retesting, because the initial sync after turning on will use a lot of data and a lot of power.


    If it isn't mail and associated apps (calendar, contacts, notes) the next most common offender is Facebook. Followed by other social networking apps (twitter, yahoo messanger, whatsapp, etc). These you can kill in the Quick Launch bar (you cannot kill mail, contacts, calendar or notes that way, because, being system functions, they just restart).


    Another trick is to run the battery down until the phone shuts off. This kills all apps, and some in the thread have reported that it works for them. Probably because it is iOS itself that is stuck trying to send a messsage on behalf of an app. If you do this charge it for 4 hours with the wall charger, which also recalibrates the battery gauge.


    The last resort is to Restore the phone using iTunes. Back up first. Then Restore and set up as a new phone. Do not add any email accounts or apps yet, and DO NOT SYNC. Test the battery life. If it still drains rapidly take the phone to Apple for diagnosis; you probably have a hidden hardware problem that the update revealed. The most likely scenario, however, is that this will fix the problem. If it does try restoring your backup. If the problem comes back you have corrupt data in your backup, and the only solution is to restore again, then manually set up your phone as if it were new.

    3G on IOS can not use. Please fix it as soon as possible.

    I also tried every workaround fix i could find on the internet and im sorry to say the problem is still there. Though it is true that after nearly every iOS update that goes out, it has some sort of issue (battery, Lockscreen code bypass, etc...) through out iPhone history, i still dont understand why these issues are there, I can understand that maybe they dont have enough time to test it completely but please, if you claim that your product is the best out there, you just cannot take the RISK, do they test every new iOS with every iDevice out there??. Well all that said, Apple customer loss will be miniscule compared to the great amount of iDevice-iOS users out there. So really back to $$$$ again.

    I am not going to fix anything, and, as Apple doesn't read these forums, your message was wasted. Even more so because you didn't say why you couldn't use your 3G. And your post has nothing to do with this thread, because the 3G cannot run iOS 6.1.2. The last version of iOS that runs on the 3G is 4.2.1.

    I like how most of the solutions are:


    "Disable 80% of what your iPhone can do, after that battery will work".


    There are articles around the web stating that Apple is working in 6.1.3. They do not mention a battery fix, but I do hope they are looking into this issue. (As I said, I hope).

    Are any of the battery apps out there any good? Rather than the "try everything" approach, it would be nice to see an estimate of which apps and functions are actually consuming the battery life. This is a standard feature on Android, though accuracy is questionable.

    If you read what I posted I said nothing about disabling anything. And I agree that you shouldn't have to disable anything to get decent performance from your phone. I don't. I run with all features and notifications enabled, push email, 2 Exchange accounts, iCloud, an iMap account and 3 POP accounts and I get good battery life. (Meaning I don't need to charge during the day).
