Battery issue

[Onetenny]

I have a s21 ultra and a Samsung  tablet. 

I've noticed the battery on both devices has gone really poorly since I upgraded.

I have both the s21 ultra and tab s7 and find both excellent for battery

I have also s21 ultra and tab s7+. Battery life is great. No issues.

I have s21 ultra and battery drain has been worse since last UI update..

Try clearing system cache on both devices. No issues here on my S21 Ultra.

I noticed battery life has gone down slightly since the last update, but I can still get 11h SoT so not too fussed.

You see I think with this it depends on the settings, my s20 now gets a decent screen on time after setting it up right however the stand by is dreadful this is due to location tracking so the more I drive the worse the stand by, my tab s7 if I use 60hz with adaptive brightness it lasts forever if I use 120hz and have the screen bright it goes much quicker. As for the update for me personally on the s20 it has made it better.
