Severe battery drain after one UI 6.1 update

[alex-f]

Updated my s23 ultra to One UI and the excessive battery drain is extremely noticeable.

Have contacted Samsung support multiple times and have been given different info each time, ranging from the implication that I am just making it up through to half acknowledgement of the issue.

I paid a lot of money for this phone mainly because of the excellent battery life; now my battery is performing worse than my cheap OPPO work phone. Samsung Support seem to be clueless and don't really seem to care. 

I will not be wasting my money on Samsung again.

Have you installed the April's patch?

[alex-f]

Yes. This issue was present before and is present after with no change.

Lots of people reporting excessive heating as well as fast battery drain too.

I am having the same issue. One UI Home has used 43% if my battery life today, is there a fix for this?
