My iPhone 6 won't charge and keeps restarting! I know it is low on battery and when I plug it in it goes through the startup process. The second it gets to my home screen, before I can manually unlock it, the shutdown circle appears and it starts to reboot again! It is plugged into my laptop and doesn't seem to be picking up any charge even though it has been plugged into my car outlet and now my laptop outlet for over an hour!
I can't even call Apple Support because I can't get into my phone to get the serial number! I have not done the iOS 8.4 update yet, so am still running 8.3. Please help!!
