I've got one UI 7, but I haven't installed it yet because I heard that it drains the battery too fast. Could anyone please share real experience with it?

Finally I have received One ui 7 for my s24 Plus today. Will share my experience with new update in next few days. 

I recently purchased the s24 plus. It a almost new set, and I have personally activated CPID on it. I am quite frustrated with its battery drain issue. The battery drains from 100 to 20 in 5 hours at standby mode. I have checked all battery settings....

Why does the NFC feature on my S24 Plus get on for a while and then automatically turn off? Could it be something? 

I just got the S24 plus, it's brand new. I'm feeling like it's heating up like a furnace, especially when it's charging. Maybe it's because the battery drains too fast. Can anyone tell me where the problem is?
