OneUI has nothing to do with battery life. That’s Android side impact. After updates there are some necessary background processes that sometimes eat up some battery faster than usual. but the UI is just the pretty buttons and pictures. It changes the efficiency of battery use of the UI itself, but the overall management of power is handled by the system and that hat a greater impact on battery life.

In a matter of a week or two I upgraded from UI 5 to 6 to 7.
The move from 5 to 6 more than halved my battery life instantly.
In one go my phone went from lasting about a day and a half roughly, to needing to be charged by just after lunch time. Absolute disgrace.
So then I upgraded again with all the promises I’d read that it has improved performance and battery life and it’s dropped at least by another 15%.
My phone is lucky to make it to lunchtime now, thanks to these upgrades.

Did you give it some days to finish processing in the background? That eats battery until it is done.
