iOS 5 battery issue resolved

[HuskerSkip]

After updating my AT&T iPhone 4 to iOS 5, my battery life dropped dramatically. Under iOS 4 my battery would be in the 70 - 80% range after a full day of use. After installing iOS 5 my battery was under 50% after about 5 hours and was under 20% after 8 hours. Turning off location services did not help.

My original iOS 5 install was followed up by a restore of my iOS4 settings, which were probably restored from an iOS 3 install.

I finally restored iOS5 and did NOT restore from a backup and instead manually installed all apps. After doing this my battery life is back to normal, if not better. I have push email and location services turned on. My battery showed 100% after nearly 3 hours.

I don't know if it was a bad app or remnants from the old iOS backup that caused my battery drain. Whatever the case my battery life is much better now. Hope this helps others solve this problem.

Did it keep all your game saves when you did the manual add? Did you restore the phone as a new phone then sync apps?

...My battery showed 100% after nearly 3 hours....

You're saying the device was running for 3 hours and used 0% of it's battery power? That's not possible.

I set my iPhone up as a new phone (before even reading what you wrote) and my battery life has been horrible. I may actually try restoring from an old back-up.

I didn't have any game settings, so can't comment on that.

My phone was in my pocket for nearly 3 hours with no activity. It showed 100%. After a few minutes of use it dropped to 99%. So yes it is possible.
