Battery Drain after Update to One U.I 3.0

Hi.

Has anyone experienced battery drain on their phones after new update? 
I'm using S20 5G and it's draining about 1% every 2min or so. This is even when phone is on Standby and not using data.

I have more than 90% of apps in Deep Sleep and only apps that are running in background are my email and Bixby Routine (which is for keeping brightness low when using apps)

(In process of writing this its depleted 5%)

Any ideas/advice would be appreciated!!

im bloody experience it but throughout the day lile samsung notes app been killing my batterg terribly , pictures got deleted twice due to doing factory reset which resulted in being pointless , let me show you an examples, look at nova launcher which has been running fot nearly 19 hours and only taken 0.4% battery and now look at Instagram used it for like 3 minute and its already taken 1% like wtf ?? and all these apps are in sleep mode , except the samsung notes which was the main issue , now all this is happening with other apps
