Preform after one ui 4.1 update

[vishal955]

After updating my s21 ultra on one ui 4.1 performance reduced to half and heating, battery drain issue just got doubled

I am also using s21 ultra. I am getting good battery life after one UI 4.1 almost 6 hrs SOT. The phone is getting slightly warm maybe because of the ambient temperature. Also don't believe in benchmark tests.

SOT has definitely decreased, causing heating issue with battery drain. Please report it under Get Help option.
