Something weird happened in the last couple of days: last Saturday my brother's iPhone (4 on 5.1.1) somehow "died", he asked for my help. It wouldn't turn on, had to force DFU mode and restore it. His power button has kind of gone bad, and I blamed it plus my brother's incompentence. The reason I'm creating this thread is that the same thing happened today to my iPad (3rd gen, running iOS 6 b2). I thought I didn't charge it tonight but it wouldn't work even while charging, I tried DFU and restore and the battery is in fact fully charged. Is this happening to anyone else or just a weird coincidence?
