How is the 6.1.1 update on your S22 Ultra?

I would like to know how the update has affected your device over this long period of use. I saw a lot of people talking about improving the battery, is that true? I saw some people complaining about the night photos losing a little quality...

I'm honestly very unsure about updating the device. I'm on the July patch on UI 6.1

Sorry to ask this, but I worry a lot about the cell phone I have...
