S21 FE battery drain

[Members_EOUGeDg]

I got my s21 FE 1 week ago. I have never had a phone before when the battery drain as fast like the s21 fe. 

If you are lucky you get 2-3 hours screen on time. The biggest problem is that the battery draining very fast in idle. 10% in 1 hour when in not using the phone.

No matter if im connected to wifi or 4g(dont have 5g connection).

Always on display is off. Brightness on screen is low. Location services is off. I have all my apps in deep sleep mode when not using them. The only thing i do in the phone is browsing the web. No gaming, No video, No audio.  I get 7 hours screen on time with my 4 year old oneplus 6t with the same type of daily use. 

Anyone else expering bad battery time with s21 fe?

Had horrific drain and tried this
On WIFI settings go to advanced and turn on WiFi power saving mode. Was lucky to get through the day without charging once but used 48% in 12 hrs today

This is the costliest phone that I ever bought and have the worst battery life. My 3year old phone still lasts more with full on screen time than S21 FE in idle state. ***** this phone.

Never heard anyone before talking about this option.

I've turned it on hopefully it does something to the horrible battery drainage
