Why am i thinking that one ui 6.1 is better,smooth and good performing than one ui 7 

This morning my s23 suddenly shows that WE HAVE DETECTED SOME MOISTURE OR "EXTERNAL MATERIAL IS YOUR. HATGING PORT" what should i do to sol e this problem.

I have s23 5g . After updating to one ui 7 its bettery consumption is very high. Even after light usage. It giver 1.5hr screen on time on 53% bettery consumption. What can in do. On light usage it gives me 3 or 3.5 hpurs of screen on time 

After this update my phote automatically switched off many times a day . And in camera in pro mode zooming is not working.
