After updating to One UI 8.0 my Samsung S23 battery health deteriorated, not able to use for more than 4hrs

Hurray finally got One UI 7 update on S23

According to some sources One UI 7 arriving on April 14 for S23 along with S24 and flip models???

Iam using S23 from past one year, it's working fine but I observed that from past 2 days at night it's getting froze at sudden for few seconds and is getting restarted again, any one facing similar issues???Is it due to overheat or any hardware issue...

When will Samsung S23 get One UI 7 stable update??
