Random restarts / Bug Type 115

Dear Coomunity,

I have this problem since December 2022, every day my Iphone 12 Pro max restarts 5-6 times, regardless of any specific app. It can also restart, when I don't use the Iphone at all or at night.

This problem has nothing to do with the memory capacity (currently I have 32 GB free) not even with HW damage. I never dropped it on floor or into water.

First the screen freezes, then the spinning gear appears and the Iphone turns off, after a few seconds the apple logo appears and the Iphone starts again.

This is very annoying, I know that many of you had this problem, but I don't feel like resetting the phone to factory settings and losing a lot of data. Could someone solve this issue?
