For a little over a month, my iPad has been restarting randomly several times a day on the days that I use it. It's under warranty since I purchased is Jan 2018, but I didn't buy AppleCare. It''s been running iOS 11.4.1 the entire time that I've been having problems. Some use cases when it will restart Connected to wall charger but not being used. Connected to charger while being used. Not connected to a charger but not being used. Not connected to a charger while being used. Before I sent to Apple for troubleshooting and repair I: Did an "Erase all setting and content" followed by a restore from iCloud back. No change in symptoms. Did 5 separate "Erase all setting and content"'s and set the iPad up a new. No change in symptoms. Checked for dirt or anything else in the lightning port . Clean as a whistle. Apple tech support troubleshot it with me over chat, and then had me mail it to them so that their techs could troubleshoot it. They said that they could not reproduce the issue or find any other problem, and they mailed it back to me. I got it back this past Tuesday. After I set it back up, this time restoring from iCloud backup , I rebooted while I using it on the train during my commute to/from work. It rebooted 3 times yesterday , and rebooted 2 times today, so I am critical that Apple tech support could not find a problem with it. I can literally log into it , leave it laying around, and check the lock screen and see that it has rebooted. I know when it reboots because it asks for the PIN after each restart, otherwise I can use touch id to login. Options I'm considering: It might be an iOS issue, so perhaps joining the public beta for iOS 12 might fix it. It might be a hardware issue, like a bad area in memory that as soon as an app tries to access it, the system reboot. Setting up an Genius Bar appointment. If #1 doesn't work and I then try #2 , Apple techs might just blame it on the beta ( currently public beta 3 ) and send me home. #2 might be a waste of time based on how Apple online tech support handled it. What would you do?
