Hi same here, I've done a factory reset seems to still be draining, give it a few days & let's see if it settles down.
It might need a few charging cycles before things start getting better.
Hopefully.

S21 ultra. 4 days after the update I still get extreme battery drain like 40% over night. Used to be like 10% max.

Thats terrible hopefully the next update will fix that.

Same here, S20 FE 5G in my case, after upgrading to one UI 4.1
How should we report this? 

[jas123456]

Try and report it to Samsung.

Same here.. S21U, Snapdragon variant.

I flashed the One Ui 4.1 update via Odin, (restoring absolutely everything from factory), but the battery drain is beastly. I remember that before it gave me more than 1 day in Device care, now it gives me 14 hours.

It's definitely a software issue.
