Does anyone have this issue wherein after unplugging your phone [ overnight ] it seems dead ? I've had this issue twice... Had to hold down the home + power button to get it to boot !! I'm having similar [ wake from sleep ] issue with OS 10.9 [ Mavericks ] where the computer has to be booted up [ holding down the power button ] because it never wakes up from sleep! Also, the battery [ after being plugged all night ] was at 90% when I finally got it to boot. I have submitted a bug report to Apple regarding the Mavericks issue, but I'd like to know if others are having a similar issue with iOS 7 before filing a bug report for this one too.. FYI: I'm a registered developer for both iOS and Mac OS, so these aren't bootleg installs. Thanks!
