    Did you try fresh install without restoring your backups?

    No. I did restore from the backup i made before installing the GM. Battery life was great on the last Beta. So i figured it wouldnt be an issue with this one.

    My battery life seems normal on my iPhone 4 so far. Maybe even a little better than 4.3.5

    Do you have a reminder with a location set for today? i noticed that if you have it set up like that, the phone is constantly searching for you location, until you reach the destination, so it was draining my battery.

    If i start it as a clean restore, can i still sync my contacts and such?

    Just check the usual battery drainers, there is nothing wrong with mine.

    My worry that the battery on the 4S is worse than the iPhone 4 is the only thing making me question whether to get it or not. Battery life is pretty important to me

    I did a restore on my 4 and my battery is no worse, maybe even a little better than with 4.3.5. If I'd leave my phone on overnight sometimes I would lose 1%-2%. It charged up to 88% when I installed the GM, used it for about 30 minutes or so last night, let it sit overnight, and used it this morning to shoot out a few texts and emails and now it's at 87%.

    With 4.3.5 I could get about 3 days of standby and 5 hours of usage before my battery drained completely.

    I noticed my battery was much worse today with the GM than on Beta 7; turned off iCloud for Reminders and that did the trick. Up until then, my Standby and Use time had been the same even if I rebooted the phone. And the device was getting hot to the touch.
    The rest of iCloud is on...not sure what about Reminders did it. But the standby and use times are different now and the battery stopped draining crazily.

    I installed it and restored from backup.

    Im having the same issues. Battery is draining and some of the apple apps like calender, phone (contacts), and reminders are glitchy.

    I had the same problem, but I found that sometimes the software installs funky.

    It's not a problem with the backup, so don't worry about that.

    DFU restore the phone and then restore. If that doesn't work, try, try again.

    It normally would take 1-2 tries when updating to the newest beta to get my battery working correctly.

    I performed a restore again last night. Went to bed and my battery life was 93%, woke up and it was 43%... did two things on the phone this morning for 5 minutes and it dropped to 39%.

    When i first installed GM I was having the exact same issues that you were having. As it turns out, my phone was downloading things that i had before the update. it was putting a lot of apps on that i didn't need/want anymore. Once I got all that stuff deleted/stopped, i noticed that it has a little worse battery life than the previous version, but nothing too drastic.

    I restored from backup and haven't had noticeable battery issues. I wonder though: with location based reminders does the GPS have to be on all the time? Could that be the culprit?

    iPhone 3GS running iOS 5 GM

    I found a lot of GPS/location use with "traffic" and "set time zone" options turned on, which they are by default. You can now turn those off under settings>location services>system services.'

    My 3GS doesn't have location-based reminders.

    I am having the same severe battery issue on my iPhone 4. The only thing I have been able to come up with is that removing my work Exchange account from the phone resolves the battery life issue. If others can confirm that, it would be helpful. The only issue is I don't know what would cause that as it worked just fine in all of the beta's.
