Android 13 update battery drain

[Andytechnut]

Since update to 13 battery is draining very quickly I. Going down to 50% well before lunchtime where prior I would still be at 65 to 70%

I'm having the same problem with s21+ draining very fast.

Android 13.....my battery is also draining faster, phone always restarts itself overnight now and whole experience just seems glitchy. Hope an update to sort the update is available soon!
