Ezotericar I did this a week ago. As for results? Battery optimisation were taking 2-3 days but today I got more than 7,5h SOT - charged np2a on friday and I have now 26% left. I disabled many setting connected with location and with nothing weather app - I don’ use high accuracy location with almost any app ( only with google maps) and limit the location usage when the apps is in use - not in the background.
On a side note the camera after factory reset seem to be a bit better but the color accuracy is sometimes off especially with red colors.
