Phone is getting shut down automatically

[Bintush]

Hey, everyone. I've got a problem with my S23 Ultra since the UI update. It keeps shutting down on its own, and then when it restarts, like, 40% of the battery is gone! I even did a factory reset, but it didn't help. Any ideas how to fix this?

Factory reset, after evry major updates you need to do a Factory reset to avoid glitch. Make sure you take backup
