Proper battery care in Xperia xz

[xznewbie]

Hello guys.. May I know the optimum battery charging capacity for Xperia xz... Do I allow it to get down to 15% before recharging, or have it continuously topped up whenever it's near the AC outlet..?

Hello guys.. If your XZ is in stamina mood and the display is just 35%brightness. I GOT this value in battery used distribution :
Screen 23%,Facebook, 13%,Google play 12%,phone idle 12%,android OS10%,, chrome 4%,camera, 3%,cell standby3%, email 2%0, Google app 2%,viber2%
Now my question why does phone idle consume moderate battery power, as well as 1,sim in standby.
Does an idle function or in standby still consumes power?
Is it not for dual sim if one Sim us deactivated, and phone us idle there should be negligible power consumption. As I noticed if Both Sim cards are active there is an effect in battery life.?
What are your experiences with it. IS my situation normal.?
My xz is fully charged 100%at 7am.but become depleted at 6pm (15%power left).. I only occasionally surf at LTE, maybe 5times a day, running Facebook during that whole 7am to 6pm.
From your experience is my battery consumption normal or Abnormal..?

Why did you had 2 accounts?

That was before as when I logged with my almost forgotten account,upon getting my Xz (that it was not used often) then. This site won't accept it, so I have to make a new one.
I think it was already removed by then... But your question is irrelevant to the thread..

Now does anybody have any idea about the battery usage distribution thread which was attached to this old thread?
