since updating to ios 6.1.1, my battery will completely deplete after a 100% charge in about 6 hours with limited usage (checking calendar, checking mail, and maybe 10 mins of talk time. anyone know about this?
iPhone 4S, iOS 6.1.1
I am having the same problem after I upgraded to 6.1.1 on my 4S. Battery life was great on 6.1, usually around 6-8 hours. But it's doesn't even last until noon with 100% at 9am. I'll revert back to 6.1 I guess.
Everyone has the same problem. Hello Apple?? Anybody home? Confidence level is depleting as fast as my battery.
Is it possible to revert back to 6.1? Didn't know that was possible.
I have noticed the same thing. How would one revert back to 6.1
OK. Got it fixed. Apparently there is a bug in the software that has been confirmed and linked to the Exchange server settings.
To fix till the software is updated:
Settings\Mail,Contacts,Calendars\Exchange
turn off the "Calendars" sync for at least 10 seconds, then turn back on. Apparently this resets the accounts' syncing which is stuck in a continuous loop with the 6.1.1 software bug.
I did this yesterday and phone battery life is back to normal. thank goodness for work-a-rounds. Still have 57% tonight after all days use today. I hope this helps others.
Thank you Engine Guy!!! Everything is back to normal after executing your fix. Two thumbs up!!
