I just upgraded from the S20 Ultra and the battery life on it is awful.
Went from 20% out of the box to 0 in about 3 hours just installing and updating apps. Same process on my S20 Ultra 3 months ago and it took well over 6 hours to drain.
I just got mine 4 days ago, and the reason why I bought is because my Note 5 has battery issue. Now, both have no difference. I am a heavy user and had Note 3 and Note 9, I never had such bad experience on the battery. I bought it for the same reason - 4300 mah according to the specs. But it's like 2k mah!
So far, I haven't found any solution.
I wouldn't have to charge my phone for two or three days...until yesterday. Now I all of the sudden have to charge it twice a day!! I didn't even touch it for an hour and a half and it went down 18%!!! After work I was at 50% and I am only at work for 6 hours, during which I rarely even check my phone.
