S23 ultra battery drain after one UI 6.1

[Pultogard]

I'm very disappointed with Samsung after the One UI 6.1 update. My Galaxy S23 Ultra's battery life has drastically declined, barely lasting a day even on Wi-Fi. My colleague's S24 Ultra has it even worse. This experience has made me lose trust in Samsung's products. I don't think I'll be buying from them again.

This could be a number of reasons
Could be the phones Partition Cashe needs wiping. Best practice to do this after any large update anyway I think
Could also be an app or theme not optimised for the software properly. This will be down to the App developers to update their software.
Check in battery and device care section to see if something is using more battery than it should be

Same with my S23 Ultra. Before 6.1 update, I was getting around two days from a charge. Now it's just over a day...maybe 28 hours or so.
I've cleaned the cache partition and done various other housekeeping stuff, but no improvement.
Come on Samsung...own up: what have you done?

Exactly the same here since the update I only get one day before I got two days easy, infact the other day I charged the phone to 80 percent and only did a brief wattsapp video call and used the navigation to find my way around and by 4pm it was at 4 percent battery then to nothing before I got home so not very good at all really

I have the same problem on my S23+ after the update. I'm sure it is a problem with 6.1, since nothing else has changed. Too bad there is no official way to downgrade.

The same happened with me, and I have decided the same, I will not buy Samsung products again, doesn't worth.
