Just updated my mi 11 ultra to 13.0.9 via fastboot. Open pdf and upload pictures on telegram feels fine. Phone feels much smoother compare to 13.0.5 (it was sometimes buggy/laggy). Will need to test out longer to see any more improvement
Cleaner and battery shortcuts unable to open at the widget section (left side) after playing genshin impact, only resolve after restart the phone (Mi 11 ultra). Phone tends to lag also after playing games (I suspect is due to overheating).
