It's the same on mine. Google play services has taken 1.7% and has been running in the background for 16 h 49 m, since last full charge. Google play store 0.9%. I'm guessing Google play store is down to having automatic updates on. So it's running in the background checking.
Let's hope one ui 3.1 fixes things. I have the note 20 ultra I I actually thought the android 11 3.0. Improved the battery for me. But I did do a factory reset just after the update because chat features stopped working for me. Didn't fix the issue. But I'm thinking now maybe it was the reset of the phone that improved the battery and not the actual update.
