s21 battery.

How's everyone's battery performance.  I watched a utube video of some one doing comparisons. And he got 8hrs on screen time out of it playing games, watching videos, browsing and more. I can barely get 4 just browsing and watching the occasional video. Some people are saying its the February update doing it. Not too impressed to be honest.

There have been 2 February updates for the stock Samsung unbranded, non-carrier models, CSC code BTU... AUB3 and AUB6. The first update seemed to cause an issue with battery drain and over heating for the S21 5G, whilst the 2nd update contains the bugfix for this and is being rolled out now.

I can't get anything like that.

[Benny1980]

right. i only got it yesterday and updated it. hopefully this new one is a fix and I might get it soon.

Don't know about the S21 but my Ultra can easily go 8-9 hours on WiFi on 120 hz and wqhd.
Still have 54% battery left and 3.44 SOT so can expect another 4hours if I use it non stop.

[Benny1980]

yes I'd expect 6 to 8 hrs honestly on mine. 4 seems pretty bad.

mine is *****

The S21 5G model, as per your thread title, has a 4000 mAh battery size.

The S21 Ultra has a 5000 mAh size battery, 25% larger than your S21 5G

[Benny1980]

yes I know. but the screen is bigger and has better resolution. I still wouldn't expect mine to last as long as that one but 4 hrs is pitiful is it not?
