battery backup in M30s

[Anonymous]

In a free time like this I decided to do several tests on my M30s after 7months.

Here is the battery backup I got with no power savings. In optimized mode. 

Usage:  29hrs

SoT: 13hrs

Note: After 10 update battery usage in device care is not clear so I used Accubattery app for all my tests. 

Also I seen a hidden setting of high refresh rate whether its really works or not, Idk. I enabled it throughout my test and didn't see any difference in display smoothness or battery backup. Here it is 👇👇

High refresh was present In pie too. When I turned it On back in Jan when I first purchased M30s I got errors like amazon, flipkart and other medical apps not able to view images of product saying incapatible display. When I change it to save battery it was fine. So I never used it. But now after 10 update no errors occur nor I can see any difference in display or battery.

Maybe, idk for sure. But its true that devs develop firmwares by taking many parts from any existing firmwares, and i dont think any of Samsung's flagships who came with android9 or lower had a higher refresh rates, so I assumed Samsung took the S20s firmware as a base and developed all other android10 firmwares based on that, as obviously S20 is a flagship, and its development started from like mid 2019 or even earlier. So, It would have surely packed the first oneui2, having 120hz.
