iPhone 12 pro randomly shutting off.
I have a problem with my Iphone 12 Pro it randomly shuts down and then reboots. It doesn't seem to happen if the phone is plugged into a power charger. The battery max capacity is 85% and was wondering if it has anything to do with this. I have reset phone and its still happening the phones max capacity is 128gb and around half full.
