S21 Fe has battery issues

[samz2]

It's barely been 6 months since I've brought this phone and I'm experiencing battery drain on standby mode and also less usage time. I even got the mother board replaced and also the battery was checked and now the service centre executives claim it may be a software issue and a lot of S21 FE devices are experiencing the same issue. I've spent a lot of money and this is just infuriating. Samsung do something

My dear turn on power saving mode, location turn off, when necessary open than close. Stop all background apps, stop adaptive brightness, stop vibration, remove unused apps, turn it on safe mode. Thanks.
