Battery issue after ONE UI 7 update for S23 Ultra?

[Paua]

Has anyone else noticed their battery draining faster since the update?

I updated to One UI 7 when my battery was at 60%. Two hours later, with normal usage (mainly looking through new features and settings), it's now at 42%.

Yeah! Eversince the update, the drainage of battery has been significant. Maybe, It'll adapt in a few days or they will push some fix or something.
