System UI battery drain on S21 Ultra

[Dannyboii]

Hi I have noticed that since updating to android 13, that when I check my battery usage, System UI seems to always be at the top of the list of apps draining my battery. Anyone else have this issue?

Here is an example. I've also noticed Google play services is always at the top too

Hi @Dannyboii 

Battery stats appear to be on par with Android¹² I was on until Android¹³.

Can you try > 

Clear Cache Files from the phone's System Partition Section  > https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to insert your earphones or hook upto a powered On Laptop to access the Clear Partition Section. This may help with lag or stutters as this clears the phone of old/unused or broken cache files.There is also a Repair Apps option in the Menu System too.

Hi I cleared the cache and repaired the apps and it seems to be better now

I have also noticed excessive battery drain.  The only solution that worked for me was change refresh rate back down to 60. Motion Smoothing > Standard. 

I read that it may stuck at 120 all the time thus the huge drain.
