iPhone 4S battery not charging completely
I plug in my iPhone 4S before going to bed and charge it over night (6 - 8 hours). When I wake up in the morning most of the time it has only charged to somewhere between 93% and 97%. If I unplug it and plug it back in the charge will complete to 100%.
This has happened with several different cables as well as an Apple iPhone dock.
Has anyone else had this issue, and what could it be?
iOS 5
