I have a iPhone 7 that showed a dead battery last night (although I do not think it was anywhere near dead). I plugged it in the charger and it has been rebooting to the Apple Logo over and over. It out of the blue allowed me to use my passcode and get in a few hours ago so I backed it up in iTunes. I did a reset to see if that would clear the problem... uh no. Shortly after it went back to the reboot cycle and has been there ever since today. Kind of a bummer when I want to call family for Christmas. Any thoughts, suggestions, input? PS - Merry Christmas!
