Keeps switching off

[danabutchers]

I have s21 ultra last 2 weeks phone just switches off on its own sometimes restarts other won't switch off for several minutes.

I've factory reset the phone I've removed apps I've checked auto optimisation plus all other settings and still does it.

Anyone experiencing the same or similar 

Thankyou

My wife's phone has been having this issue for a bit over a week now. Still restarted in Maintenance mode. I've also restored the phone to factory settings.
