After one ui 7 I never had a good battery life. I just saw this and im shocked 😲.usually for 5h battery drain like 80 to 90
One ui 8 is good 
Yes i think have improved battery compared to One UI 7. This is my SoT yesterday. 
Yesterday whole day I was at home. On these days and battery performs well. And today i went whole day out and then with the battery percentage used with the device the screen time is less.
