Not happy iOS 6.1

Try a few things like restarting the phone, disable some unnecessary location services, and look at your push/fetch settings for mail. If those don't make a difference, try restoring your device.

If you've looked at those settings and done a restore, calling Apple Support may yield additional solutions.

Have you restored your phone as NEW.. then see how the battery life is, then you can sync back your contacts, apps, music.

Resetting will most likely resolve it. However there is a simple reset that helps a lot of the time that does not wipe out your data or apps. settings>general>reset> Reset All Settings. When the device reboots select "Set Up As New". Again this does not wipe your stuff even though you select setup as new but rather resets the settings and wallpaper etc. You simply go back and configure your location, notification etc etc settings. Turning off the system settings all but cellular,compass and traffic will also help. As does diagnostics and usage. None of these will you miss as a "feature" but will help the battery life substantially. This reset all can be done in a few minutes. If that doesnt resolve it you may need to remove your email accounts, reboot and add them back. Again this is a known cause of excessive drain and removing and re-adding them solves whatever the update hosed up.

Lastly a full restore via iTunes or DFU restore should resolve it. Of course that takes a little time but not like hours and hours. iOS 6.0.1 itself is not the cause of the drain. Its a corrupt setting or app or email account that got hosed during the upgrade that is most likely the issue.

in my instance, it appears that the push of the email app is my problem....I want to note that I did not have this problem prior to a week ago and my phone battery drain was what I call good prior to that......some afternoon monitoring has produced this...I am going to turn everything but the push (all notifications and location services):

Before shutting down, it was losing 1% about every 5min or so....notifications were already turned off

1:00pm - complete shutdown

1:08pm - turned on phone: 73%

1:18pm - 73%

1:28pm - 73%

1:38pm - 73% NOTE: since it has been turned on, I've only woken up the phone to see the slide to open screen. I also noticed that the wifi has not connected yet and that the bluetooth status is up but off. there have been 2 words with friends game notifications

1:48pm - 73%

1:51pm - 73% NOTE: logged in, wifi connected, put back to sleep

2:01pm - 71% NOTE: wifi full strength...iphone literally 3ft from the wifi router

2:06pm - 70%

2:16pm - 68%

2:31pm - 64% NOTE: disconnected from my wifi network by forgetting it, but left wifi on

2:50pm - 59% NOTE: turned off wifi

3:02pm - 55% NOTE: eliminated all app processes, turned off email push

3:23pm - 55%

3:38pm - 54% NOTE: turned on wifi

3:48pm - 54%

4:03pm - 53%

4:45pm - 49% NOTE: includes 22 minute phone call

they should put widget on the lock screen i hope they put it in IOS 7 and put new features in IOS 6

I want to update everyone.....

I have everything turned on and the only thing I have changed from default is that instead of push on my email, I use fetch every 15 minutes.

after a full charge last night, 40 minutes of use and 4 hours of standby, and my 4s is at 99%

when I began trying to isolate the drainage problem, I started with cycling full power and leaving the phone off for 10 minutes.......then I started peeling the onlion as in my message above.

it may be a different app for others, but the same approach can at least get you to a place where you know if you turn one thing off or change the way it operate, it can get you to a place of acceptable battery drain.

it may be that app standards don't rule out endless loops enough

Is this an Exchange email account?

I have an exchange email, gmail, and icloud.....I guess I could do some more narrowing down, but the difference is negligible to me now and my battery life is good and I have other things to do.....maybe over the weekend

it would be nice to have a real time power usage meter....then everything could be analyzed relativley instantly

Start with your Exchange account. It sounds like there was a password issue during the update that causes the phone/Exchange connection to constantly poll each other. Your Exchange admin can check his side to see if this was happening.

I will do that......I haven't had to update my PW for exchange for some time .....thanks

the push is constant though....I get my emails on my phone before they show up in outlook on my desktop, so something is constantly working at it
