Poor battery on s21 ultra

[Josu99]

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.
are you using fast charging and super fast charging option always!!?

[Josu99]

Yes super fast charging.
And its only 2 weeks since i took new s21 ultra.Should i visit service center or hope it will better by time.

[SHINAN-EpFBz]

never ever use fast charging option unless it's emergency
please see the comments from Samsung

But its the normal 25watts note 10 plus adapter i use for s21 ultra.its ok right?

[ProgRidha]

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

[SHINAN-EpFBz]

you can use adapter
but turn off fast charging features

[ProgRidha]

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 new
