Battery Draining Issue One UI 8 Update

[Giyu2000]

Hi guys, I recently updated my Samsung Galaxy S23 from One UI 7 Android 15 to One UI 8 Android 16. After two days of using I noticed there's a massive drainage of battery is happened. I use the battery protection mode even though when it reaches 20% charge its battery drains so soon. Also I attended an exam yesterday via online I charged my phone upto 80% and Started attending the exam by 9 am when After 1½ hours exactly at 10:30 am my battery percentage dropped in to 45 percentage even though I'm not using my mobile network it reached this much no other background apps aren't running either just connected to my wifi if I were using my mobile network 5G surely it will drain I noticed it in One UI 7 but in wifi I get a full day battey life this is so concerning I have 3 hours exam by 2 hour the battery percentage dropped in to 35% and after the exam I used my phone for my usual things by 6pm my phone was dead. Did anyone have the issues of battery draining after updated to One UI 8 please let me know whether I'm the one only having this toruble with this new update. I hope Samsung will clear this by their next updation.
