Hi guys i am getting only 3.5 hrs screen on time on my s21 ultra.
Phone is set on fhd with 120 hz.
Feeling so so frustrated with this battery.
Is it natural or a complaint.

s21 have a powerful battery capacity.. minimum you will get an 8 hours backup.

Yes normal to use the 25 watt adapter but disable fast charging / super fast charging in battery and device care menu unless u need it urgently

It's not normal at all I have same device with no issue in battery life

Under setting go to battery and device care then press on battery from there press on the graph 📊 then it will take u to the app list that used your battery most with detailed (active and background use ) see which applications use your battery the most in the background try to put it into sleep or deep sleep

Also don't forget to press optimize now in battery and device care

I will attach some screen shots to be more clear


If this didn't work I suggest you to take it to service center since the device still newScreenshot_20211115-025014_Device care_43553.jpgScreenshot_20211115-025005_Device care_43551.jpgScreenshot_20211115-025035_Device care_43557.jpgScreenshot_20211115-024953_Device care_43549.jpg
