Terrible battery life

[o6np7]

I've had my s21 plus with exynos for months now and the battery life is really terrible. Barely able to get 3 or max. 4 hours. I use 120hz with bluetooth and mobile data off and have strong signal. This should not be a problem as I've seen people with those settings turned on get 6 hours and more of SOT. 

This isn't normal, is it?? What should I do?

Hi,
Have you tried using device care
To put apps to sleep When not in use

The 120hz mode will be killing the battery if you swap to power saving mode reducing to 60hz it will improve alot.

But I like to use 120hz and that way I paid for a phone with a feature that I can't use. And as I said, I've seen people that use 120hz and still get 6 hour screen on time, though on snapdragon.

Yes I have put some of them in sleeping mode.

Yes, I have a Z Fold 3 and if i use 120HZ it just kills the battery (Although i'm playing intensive games on it) the phone does have a Snapdragon processor but supposedly the 888 5g has a tendancy to overheat and throttle performance.

Yeah sounds like a fault. I have S21 (exynos) and I use 120 hz basically everything on and in one day I do about 3-4 hours sot which depletes the battery to 50% by 8-9pm. I reckon I could do 2 days on battery its just Im out all day so I still charge it every day. But yeah defo sounds like a fault with your phone, so I wld send it to where it came from to see if u can get it fixed.
