I went to sleep last night and my phone was at 98% I woke up today and as soon as I touch the sleep bottom to use it, it turned off. There wasn't any apps open, in the background I have my photo stream off, my mail push notifications off. I went to the apple store to get my iPhone replaced, but the "Genius guy" said the battery was ok and that was probably me using games, and I told him that I don't use games, I restored it with and without backup, I've download 6.1.4 different times and the problem still occurs and he wouldn't replace my phone even though I showed him pictures like this. The 5% screenshot was taken this morning when my phone turned on and the 75% one was yesterday morning. Should my phone drain during stand-by like that normally or what?
