    You could read some of the messages in the thread you posted to and see how other people have fixed it. Note, however, that this thread is for people who did not have a problem with 6.1 but did with 6.1.2.

    I had the same problem when upgrading my iPhone4 from 5.1.1 to 6.0, and again when upgrading from 6.0 to 6.1. I am very reluctant to do any more upgrades until the problem is solved. It isn't that Iwasn't able to fix the problem, because I was. It is that it is a pain in the a** to have to do so.

    Have any of you having continual battery drain monitored the phone's log files in General-About-Diagnostic & Usage or installed iPhone Configuration Utility, connected the phone, and seen what the live logs are saying when your phone is draining? If there is bad behavior on battery drain there should be some evidence of it there.

     

    Here is what worked for me:

     

    Reset All in setting (Settings-General-Reset-Reset All Settings).

    Remove all email calendars (Settings-Mail/Contacts/Calendar).

    Trim apps w/access to location services (Settings-Privacy-Location Services).

    Actively shutdown apps not in use (double to home + hold to kill apps).

    Monitor app usage (General-About-Diagnostic & Usage).

    For those of you who don't have the issue and your are on 6.1.2, are you on the iPhone 4x or 5?

    4S. No issue on 6.1.2.

    Now it's 2hours 18 minutes of usage,2 hours 39 minutes standby and I was using my phone the whole time.

    Got it! This is a misunderstanding of what "standby time" means. "Standby time" is actually "total time since last full charge". It doesn't stop counting when the phone is actively in use ("Usage").

    @Lawrence Finch

     

    I have been following this and the other threads on battery drain.

     

     

    I have an iPhone 4. Updated OTA from 6.1.1 to 6.1.2 shortly after 6.1.2 became available. Ever since upgrading to 6.1.2 I have been experiancing major battery drain.

     

    I have tried almost all the fixes listed here. The only one I have not tried is restoring the phone from iTunes.

     

    So far I have managed to slow the drain with each fix attempt. I do have an interesting discovery though. After putting Mail on Fetch instead of Push, after restart battery level jumped from 81% to 90% and the drain was slower but still faster than normal. I read on another thread and/or forum something about the camera process not closing right. So I turned off FaceTime and restarted phone. After restarting phone my battery drain is almost back to how it was on 6.1.1. I ran it a few days like this. Then tried to turn services on one at a time. Turning on FaceTime caused drain to increase, and turning Push back on along with FaceTime caused drain to increase more.

     

    So for right now with FaceTime and Push off my battery is almost like it was on 6.1.1.

     

    Any ideas why this combo is "fixing" my battery issue?

     

    And repeat, I have tried ALL fixes in this thread EXCEPT restoring from iTunes.

     

    Thanks in advance,

    I think what you have discovered is that battery drain is a symptom that can have may causes. Which is why different people report improving their battery life with different changes to their settings. It has always been thus with iPhones (and Androids, also, but you don't read about them here). At some random time the battery life suddenly drops noticeably. It frequently, but not always, occurs after an update (any update, not just to 6.1.2).

     

    My experience is that virtually all of the different causes have one thing in common: An app (or several) that is stuck running continuously. I hadn't heard about Facetime, but it is quite plausible. The most frequent offender is Exchange; the Microsoft ActiveSync protocol is very complex, and has always been a little buggy because with the complexity comes an inability to test all possible interactions. The reason an app runs continuously is data corruption in the app. It's likely that the problem arises more often after an update because the update process itself halts all applications in whatever state they were in, and, if it was sending data the send is incomplete and the app does not know how to recover in the middle of what it was doing.

     

    A Restore as New is the only way to purge all corrupt data; it sounds like your phone has more than one app with an indeterminate state. Sometimes terminating all apps will force them to start over. And the only way to do this is to run the battery down until the phone shuts off. A Reboot does not achieve the same result, nor does killing the app in the Quick Launch bar. So I suggest running the battery all the way down before restoring as new; it can't hurt, and might resolve the problem.

    @Lawrence Finch

     

    Thanks for your reply/help thus far.

     

    What you said makes sense about the apps hanging and unable to recover.

     

    I did indeed try the run down the battery method. That was the "fix" I tried right before turning Push off and turning off FaceTime.

     

    With FaceTime and Push off, battery is similar to pre 6.1.2 drain, but not as good.

     

    Been trying to avoid a restore just because of the inconvenience, but that might be the next step.

     

    I do have some questions about that.

     

    When I do that, my phone will restore the ios/firmware/settings/etc to stock. None of my apps/settings/etc will be on phone correct? But my number and everything will still be the same? I can then restore from backup to get my data back correct?

     

    Thanks,

    It will restore to a "new phone" state, but will still have your number because the number is associated with the SIM (except for Verizon it is associated with the IMEI, but same concept).

     

    Be sure to disable automatic syncing in iTunes Preferences/Devices tab, and don't sync after the restore. Choose to set up as New when prompted. Test it to make sure the battery drain is fixed. Then restore the backup with iTunes. Wait a couple of hours before checking battery drain, because it will take time for the apps to resync.

     

    If the problem comes back there is corrupt data in the backup, and you will have to restore again as New, and this time add back your apps and content. You will lose app data and settings.

    hello gher03!  i have an iphone 5 from hongkong and i am using sun cellular sim.  i also have problems with the battery.  when you say remove the sim, you mean to use the phone without sim card?  i also think this is a network carrier problem.  ever since the 6.1 update, i noticed that my phone heats up when i go to some places with low signal strength.  not all carriers are up to date with their technologies, so maybe apple should make the ios backward compatible.

    @Lawrence and Rory:

     

    Did as you suggested.  As a comparison, on Friday at 6:00 a.m. I began the day with 100% charge.  On Sunday at 2:00 p.m., I still had 65% charge.  Very good!  This was while I had it set on "fetch".

     

    I then deleted the Exchange email account, hard reset the phone, added the Exchange email account back in and turned on "push".  For several hours, although it seemed to be using more battery charge than when I had it set to "fetch", it didn't seem too bad.  I charged the phone last night.  This morning I again started with 100% charge at 6:00 a.m.  It is now 9:37 a.m. and it's down to 88% with no use at all; and has actually dropped 2% while I've been typing this post.

     

    Unfortunately, this option didn't seem to work for me.
