Galaxy s21 ultra battery drain

Hello all , 
After updates I'm facing this nasty battery drain
Battery % literally drops in front of my eyes as before wasn't nothing like that....

My phone is on all possible battery saving tricks such as : dark mode, 60hz , hd+ , all apps deep sleep category, 5g off , fast changing off , less then half brightness, nfc off, auto sync off , location Bluetooth and mobile data off when not in use....
With all these battery saving tricks I managed to get 4 hours sot....

 At this point I fell using a budget phone rather than flagship device

Even two weeks ago decided to install new battery, and guess what new battery performs same as old one.....🙃 ( done battery calibration as well )
Installed good guardians for apps optimisation 

In device care there is no power hungry apps...
Have even done factory reset, cleared cache partition, only 5 apps downloaded rest is stock apps, disabled stock apps such as Netflix etc .

Any ideas would be appreciated , thanks🙏🙂

To be honest was only getting around 11-12 hours max when I had my s21 Ultra, I didn't look at SOT l, just how much I had left at the end of the day which was around 10% with starting at 6am to 11pm
Battery was not great on earlier phones

With one ui 5.1 it's better to leave everything on auto and/or adaptive.

I would suggest you switch to light mode and keep your screen brightness either adaptive or between 30 -50% manually and see if it makes a difference.

I know it's opposite of what is the norm but try it for a day and see.

I have the same problem with the new April security patch draining the battery on the s23 plus.

Could it be malware from a file you have opened or some bug/spy hidden app that's draining your battery. don't wanna get you paranoid? Maybe worth looking into if u still got phone in use!!
