S23 Ultra Battery Backup on One ui 6.1

[Ashu0403]

Getting great battery backup in s23 ultra on one ui 6.1 march update. 

I am happy with it , bought the device on 22nd January 2025 but haven't got 100-0% ( 10hrs of sot ) after doing march update and waited for the device to optimize then turned off the adaptive battery settings after that i am gettings around 7%-10% per hour of active drain with also less idle drain of 0.4%-0.6% per hour .

So in conclusion 

One ui 6.1 march build is best as the camera is also good as i have seen in my brother's s23 ultra with one ui 7 there is a degrade + the battery backup and heatings is also there in one ui 7

Well, I think OneUI 5.1 was the best suited for this phone. I am using it from 2023 so got to use it from its factory form. 6.1 is also good, but 5.1 was much better. I am on December 2024 patch.

How is the battery backup and device smoothness?

I have updated to 6.1 in 2023, since then camera degraded a bit, but overall its fine. Battery backup is ok. In 80 percent charge with wifi throughout the day, 5 hrs of SOT.
