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🙏🙂

Some social media apps are power hungry apps. Facebook, Instagram are just two of those. Plus playing clash of clans, I don't think that's too bad off screen and on screen time for the s21 model.

Clash of clans is eaten your battery by looking at the screenshot. Flona's right alot of social media drain your battery fast as they are always running in the background even throu you might not be in the app. Good battey performance

This is one of my posts from last year, recently upgraded to the s23 ultra. Family member bought my s21 ultra and it's still very good on battery. I found setting up some bixby routines improved battery for me. Having most features turned on when I needed them and off when I didn't need them. There are also some tips on you tube I followed to get the best battery life.

They may not have been used much but for the short time used they devoured 25% of your battery in less than an hour.
