Battery drain after One UI 6.1 update S23 Ultra

[czanek]

I'm experiencing a huge change in battery behaviour in my S23 Ultra after the One UI 6.1 update!

It's terrible! The battery life was excellent before the update, now - the phone barely survives a day, I have to charge it up during a day, it never happened before.

This has to be related to the update. I hope Samsung will fix this ASAP as this really cripples the phone!

If the fix won't happen, and some rumors turn out to be true (Samsung trying to push users to get a new gen phone) it'll be my last Samsung phone! I've paid so much money for the highest model only to have my battery life cut almost in half by a software update one year after! Insane.

so a factory reset done remotely?

You could do it yourself, but they backed up my data and did it for me. I have been using it all day. My screen time is about 1 hour, and I have only lost 1% battery life. Yesterday, I lost 80% in 2 hours, and my screen time was only 6 minutes. so HUGE improvement.

Well it worked so i wouldn't beleive everything you hear lol

So did they just do a factory reset and your still on OneUI 6.1? Or did they roll it back to a previous OS version?

Looks like factory reset and still on one ui 6.1

He stated it would go back to previous on phone but it's showing that version. However whatever he did really worked. As of 24 hours later

Wow. I really hope this will fix this issue.

I think I kinda fixed mine because my battery life thingy was showing 12h of usage compared to a day now. I haven't updated anything but I have enabled the reduce transparency settings before this. Not saying that it's a definitive cure nor I have any explanation that might justify this decision (other than following an instruction from a guy in this thread), but I think you should try it as it's really not a trade-off and you can re-enable it if you don't notice a difference. Give it a couple days though.

Did factory reset last weekend and past week it's saying 2 d 2 hrs per full charge  . Back to normal?

Can you post some screenshots of your screen time and battery life? I also did a factory reset myself and it's not looking like anything's fixed here maybe a little but I'm going to have to use this for a few days to see what happens and judge it. I would caution on saying it's fixed the first day after a factory reset.

Yeah those directions I posted that they gave me about rolling back to previous UI version were bogus. There was no option to select a previous software version.
