iPhone 11 Pro Max will randomly turn off and power back on a few seconds later
Iphone 11 pro max will randomly turn off, a few seconds later will power back on. When I'm using the phone it will freeze up then shut off. I also noticed the day prior to the random shutdowns , my iPhone would not retain my Apple Id for certain applications.
When trying to backup through iTunes on my Mac Book Pro, the iPhone will not stay on long enough to backup. If I could restore I would clear phone and start over.
