Hi, I've got an S25+ which I didn't update for quite spme time. When I got the phone last year I was mega disappointed with the battery life (and currently still am, just got used to it and to having to keep it permanently on battery saver). I've read some mixed reviews on OneUI 8. Some say it fixes the battery drain, while others complain it starts a battery drain. Similar with the mixed reviews of S25's original battery.
Whats your exp? Should I update it to UI8? Or wait for 8.5 rollout and hope it provides a better batter fix?
