Happened whilst charging, was on 39% when I connected it to the charger, fell asleep for a couple of hours woke up to the Apple logo and it restarting, it was fully charged upon booting back up.
Wonder what’s causing this? I’m also on iOS 17.1 Beta 3 so isn’t just an issue relating to just iOS 17.0, 17.0.1, 17.0.2 and 17.0.3 etc as some has suggested.
Nope, already had the latest build installed on Tuesday when it released.
This is sadly happening to others as well from iOS 17.x.x to the latest 17.x betas with 15 Pro and 15 Pro Max.
Phone seems to crash during charging for some reason, guessing a bug with the new charge cycle reporting it has now for the iPhone 15 models.
