The battery of iPhone 4 (not S) after upgrading to iOS 5.1 dies in 10-12 hours to 10% with Wi-Fi and 3G turned on.
With iOS 5.0.1 it worked for 2-3 days.
If I turn off wi-fi and 3G it stays for 5 days.
It seems that it is definetly the software problem.
The same problem appears on some more 3 iPhones 4 I know.
When the patch could be released?
iPhone 4, iOS 5.1
What patch? I actually have BETTER batter life after upgrading to 5.1 as do most of the people I know.
If you are having battery issues, I suggest you search this forum. There are literally thousands of posts with excellent suggestions on maximizing battery life.
I have the same problem with the battery running out in actually 1/2 day, and I've turned off notifications, wi-fi, etc...
gdgmacguy: I read a bunch on this forum and turned off the stuff that drains the battery. It still just wears down fast after having upgraded to 5.1...
I have the same issue. I upgraded to a 4S a month ago. I previously had a 4th gen that was running iOS 5.0. I did not have ANY battery issues at all. I did not have to charge it daily, unless I used it that day to watch an ENTIRE baseball game. My iphone 4S.
I have followed all of these suggestions on the forums:
deleting mail accounts-then adding them back, ALL notifications are off, Nothing in the notification center, Location services are off except for Only 1 app at a time-at the most, 3G is off, No apps running in the background, Deleted mail account-without adding it back, soft reset, icloud is off, all system location services are off, I reset network settings, siri is off, Auto-set Time zone is off, bluetooth is off, brightness is set to low, I have changed the cable & power source I use to charge & sync with, etc.
The end result is always the same. The battery drains & it feels warm to the touch.
My phone is 100% charged when I leave my house @ 9am, it is essentially on standby while at work because I have to keep it in my locker. By 2pm it only has 20% battery life left.
So I am unable to enjoy all of the things that make it so awesome, in order for me to avoid missing or make an important phone call.
I don't know what else to do. My next option is to take off work, make an appointment at the apple store, which is 1 1/2 hours away.
I did full reset of my iPhone and it solved the problem.
You have to do "Restoring your iOS" procedure:

Now after 17 hours, 5-6 short calls, 15-20 minutes in 3G internet with Wi-Fi, 3G, notifications and geolocation on there is 74% left.
I only can guess that some problem could happen while upgrading to 5.1.
vc007, thanks for that, I should have figured that out since upgrading my computer also caused major problems and apple support told me to reinstall that upgrade to osx lion. DUH me, but thanks, I'm going to try that now...
