Stock Rom Gone Crazy !

[Guest Naikkon]

hello first of all.

i change on my G510 font and now i experiance some new stuff.

The clock on lockscreen is moving from right to left.

and the battery is gone crazy :

play clash of clans for 15 min and the lvl is for exp 60 % after some "pochet" time the battery is 90%

and so on.

 

Wtf is the font or i'm just going crazy

stock rom is not made to be customised deeply , thats why people use cyanogenmod.

so i only change font using iFont.

what is wrong !
