Welp! Unfortunately I'm going to have to factory reset because the battery is still not up to expectations. It appears that for whatever reason after clearing cache, OneUI is still very high up on the list of apps using my battery. It was a bit better yesterday but still barely reaching the levels that some of you are getting. I was able to average about 8 hours SOT on WIFI. Based on what others are getting, something has to be off.That is certainly a lot better. As others have suggested maybe it would help to go into battery and optimize.
Hopefully it gets better as time goes on and you get closer to 10 hours SOT instead of 9 but 9 is a lot better than 6!
Hoping this fixes it. Gotta admit, this isn't the greatest first impression after being on iPhone the last few years but I really like this phone, so willing to give it a shot and see if this can be fixed.
