Before updating i thought that there will be battery drain and bugs. But now, 7 hours after updating my device, here is my honest review:
1. Battery drain: After three hours of continuous gaming, the battery drain was almost equal as One UI 6.1
2. Bugs: There are some minimal animation bugs in the software. For eg. Minor Jitters in unlocking animation.
3. Heating: The thermals of Galaxy M15 are as the same as One UI 6.1
4. Performace and lag: I personally felt that the gaming performance in the M15 is a bit improved and there is absolutely no lag to be honest.
Conclusion: Till now i have no complaints about One UI 7.0 on M15 except for the fact that they removed default wallpapers and screen recording feature, but practically speaking there is no downgrade in updating to One UI 7.0.
My review that Battery performance improved after the update and UI and animation also running smooth as well as, so In my opinion One ui 7 beneficial for m15.
