Got the One UI 6.1 update few days ago. The battery life after that has been a disaster. I have to charge my phone 2-3 times a day. You can see in the screenshots April 6th where I charged my phone (not fully) 3 times. Before this update, I was even able to use the phone for almost 2 days after fully charged.

 The problem as you can see could be due to "One UI Home Screen" which has used 80.9% of battery in 7 minutes.

Any ideas what to do? Is there a way to revert the update?
