S21 ultra - restarts and battery drain

[Ditsky]

Since the update at the end of march my s21 ultra has a huge battery drain, can barely get through a day. And the phone randomly restarts when being used. Has anyone else had this?

I have got the S22 ultra and mine also randomly restarts during the day and over night as well... You are not alone the software needs sorting out as this is not acceptable. Hopefully it will be fixed soon I keep sending in my crash logs to help them.. but still waiting for a fix.

Have you wiped the partition cache

Have just wiped it so will give it a go! Fingers crossed!

I have the exact same issue with it restarting randomly.  I cleared cache and cleaned out temp files.  When I check the power restart history under diagnostics it says "Restart after battery discharge".  And I got a huge list showing that same restart reason.  Somebody messed up on this last update.  Any idea how to keep my phone from discharging the battery?
