    Same thing here!  I have 1-32gb 4s AT&T. 3-16gb 4 AT&T. All phones in locked screen from 100% at 6:00am dead by 2:30pm. Wifi is on, Bluetooth is off. This is a iOS issue. Please fix it. We should not have to reset to factory because this is a bad update.

    Same here. Did restart, close apps and even restore.

     

    It is so annoying that every fourth or fifth update Apple releases, the Battery drains within hours. Had this now a couple of times. 5.1.1 *****.

    My iphone 4S had very good battery life until I upgraded to 5.1.1.  Mine was fully charged when I went to bed last night, no blue tooth, all apps closed.  Totally dead this morning with no usage and the screen off all night.... ARRRRGGG, when Im I going to learn not to do these upgrades... this made a perfectly good phone next to useless.

    When you setup as new phone how does it impact Corp Exchange account etc? do I get an chance to reinstall my apps or am I in a from scratch state? I tried to restore from backup and that didnt as you indicated work.

    Chris thank you very much I went ahead and did the reset as new and exactly you you indicated my iphone 4S is back to normal with the new update 5.1.1 . it wasnt as painful as I though it was going to be. thanks again for your post.  I've been on standby for the last hour and I'm still at 100% and the phone is now cool to the touch.

     

    Regards,

    I agree.  I had no problem before this update.  I do not want to delete all my application data (some of which is exclusively local to the device/backups) because a point update is causing battery drain.

    How can i achieve this without losing all my levels in games and workout app data that i have. when i got a replacement iphone a year ago i lost all my angry birds levels

     

    ------------------------------------------------------------

    Mine is finally fixed.  These are the steps I took:

     

    1.  Make sure all your apps are updated in iTunes first

    2.  Restore phone to factory settings (click the Restore button in iTunes)

    3.  Setup as New Phone <-- this is the key part.  Do NOT restore an old backup

    4.  Re-sync your Apps/Media as if it was a new phone (DO NOT RESTORE)

     

    This process seems to have fixed my issues.  I left my phone on standby on my nightstand all night, woke up this morning, battery at 99%.  Also my app crashes are gone, huzzah.

    Thank you Chris - after several visits to the Apple store with no success, I actaully had to point your post out to them.  What irritates me the most is that they claimed that "They never heard that the new update is causing issues" or "You must have changed something and you don't realize it".

     

    I went from losing 5% battery life every minute to about 10% loss an hour after preforming the restore you suggested.  Still not as ideal as it was prior to the update but at least I can walk away from a charger for a few hours. 

     

    The phone still gets very hot when I am using it for something.  Not to happy with Apple at the moment!

    Hi All – I have also experienced the battery drain issue on upgrade to 5.1.1.

    Like many on the forum I have tried ALL suggestions to resolve this issue, none of them have resolved the problem that Apple owners seem to be experiencing, it’s not in our minds as some suggest. My iPhone 4 and iPhone 3GS are working a treat under 5.1.1, in fact I believe the 3GS is running better than under 4.3.x.

    However I do think I have tracked the problem down, which I will document here, but first a list of the things I’ve tried:

     

    • - Fully discharge battery to <5% and then back to 100% and leave charging for 3 hours after
    • - Turn off all notifications
    • - Turn off all location services
    • - Turn down brightness
    • - Turn off ALL iCloud services (effectively delete the account)
    • - Reconfigure email account to ‘MANUAL Fetch’ only
    • - Factory restore to fresh 5.1.1 from within iTunes and then restore from back-up

     

    The only thing that stops the battery discharging at around 5% every 8 hours is turning off Wi-Fi during standby mode. Prior to 5.1.1 the iPad would drain maybe 1% every 24 hours in standby mode with Wi-Fi on.

    Puzzled by this I did some research to understand what the iPad is doing whilst in standby mode with Wi-Fi on, so below is a trace from the iPad system log so that hopefully someone can look at this , identify the issue and hopefully fix it in a future ios 5.1.x release:

    These repeating messages appear approx every 30 seconds the wakeup packet contains the MAC addresses for my router and iPad, so one of them is misbehaving. This may be to do with how these have been implemented:

     

    http://en.wikipedia.org/wiki/Wake-on-LAN

    http://en.wikipedia.org/wiki/Sleep_Proxy_Service

     

    Either way I believe this is the source of the power drain issue whilst in standby with Wi-Fi turned on, perhaps this could be a router issue and that is why the issue not hitting everyone post 5.1.1?

     

     

    All the best.
