IPhone4 battery draining extremely fast iOS 5.0.1
Hello Friends,
My iPhone 4 was updated to iOS5.0.1 and overnight the battery was drained by 40%. This was 7hrs while I was sleeping. Note that 3G was on and all my apps were closed. In the morning I charged the battery and again by lunch time 60% was used up. I answered a few calls.
I did not use the internet, and my 3G was on. I observed the battery lasted longer when I had iOS5. I now regret the update I did. Please provide a simple solution.
Thanks for the help.
