Battery problems after updating to iOS 6.1
Since updating to iOS 6.1 my battery seems to drain at double speed. I barely used my iPhone today but noticed that by mid morning that the battery ws down to 28%. Since there was no problem with iOS 6.0.1, is there a way to restore back to that iOS?
All my apps are always closed and the normal power saving techniques are used.
Can anyone help?
Many thanks
