here are few things to follow as I do
1.) Limit using mobile data intsead use wifi, since wifi consumes less power than mobile data
- and always keep wcdma prefered or 2g only, Never give LTE only and better avoid LTE preferred
2.)keep location off always only switch it on if needed and turn it off after using
3.) Limit multi tasking
4.) I'm not using fb app try using browser(chrome) instead if you use the app u have to use mesenger along with it but in browser you get both and less power consumed
5.) And I have set stamina mode to turn on automatically when battery level reaches 30%
I think these tips will help you and disable any apps if you no longer using it(i.e. youtube app). And keep just one app for one thing(example keeping stock video player rather than keeping many players)
