We'll need more info to better assist you

charge the phone 100% use it as you normally would then once the battery reaches 10%

settings > power management > battery > take screenshots of:

1. the list

2. tap on the graph and take a screenshot

3. back > tap on the top 4 items on the list > take a screenshot of each 

post them all here or upload the screenshots to box or dropbox or google drive or etc and post the link

You forgot one crucial screenshot 

1. the list

2. tap on the graph and take a screenshot

3. back > tap on the top 4 items on the list > take a screenshot of each 

I see that you have WiFi running all the time which could keep your phone awake, also the missing screenshot could prove this and how bad/good your network coverage is 

[TrLgr]

oh yes sry for that

so as i can see the wifi is on

@TrLgr

which makes sense, WiFi its on all the time, and keeps the phone awake quite often, it could be a third party app that its constantly syncing.

yeah but i just restored my phone and i didnt install anything 😕

This is what I would do, repair the phone with PCC > it will delete everything on the phone > use it for 2 days and then get the screenshots and post them here.
