I've put almost all my apps into deep sleep, the advisor told me to try clearing the cache on the apps which appear the highest in power consumption. So I went to the extremes and cleared every single apps cache individually. Removed them all from deep sleep, updated loads of them, used the app speed booster which claims better performance once completed. Now for the next charge I'm going to document how much battery I can achieve with the least amount of things on. So alongside 60hz on, FHD+ (can I deal with HD+, not sure, power saving mode, 9% brightness will try for lucky number 7% next, adaptive battery, all apps in deep sleep haha, take one SIM out, not connect to my watch all day, keep mobile data off as per usual, no listening to music and just browse casually and see if I can get double digits of screen on time before hitting 20% because I don't like going below that for battery preservation.
