iPhone 6S Shut Off While Plugged Into Charger
Last night before getting into bed I did as I always do, plugged my phone into it's charger and set it on the nightstand next to me. I went to bed expecting to be woken up by the sound of one of three three alarms that I have set.
I woke up on my own and noticed that my old alarm clock said 6:10 and my first iPhone alarm is set to go off at 5:30. Confused I reached over and grabbed my phone and pressed the home button, nothing. I pressed the sleep/wake button, nothing. Then I thought well maybe I didn't plug the lightning cable all the way in. I checked that and it felt seated in there, but I pulled it out and pushed it back in expecting to see the drained battery and lightning cable symbols when your phone is completely dead. Once again, nothing. I then checked the power brick in the wall thinking that had come loose from the wall, but it too was firmly where it belonged.
I pulled the lightning cable out of the phone and pressed the Sleep/Wake and Home buttons and held them down and after about 30 seconds the phone started up and I saw the Apple logo and it booted up fine. When the phone came to the lock screen my alarm started ringing.
I am really hoping that this is a one time occurance but thought that I should document it here in case other people are having a similar experience.
iPhone 6s, iOS 9.0.1
