EDIT: This counts for Lineage Os 19, I was confused with the threat I opened. I still think it should be similar?
Battery is way better. Camera is not as good, I mean everything works but as far as I know am not able to get 4k60fps. But tbh the battery and performance benefit really win. With my Setup (underclocked and some other settings) on WLAN and 20% Brightness...App Light Control, I get over 7h sot. Also AOD off.
I guess you get like 20--30% more battery without changing the settings?
