I'll try to change ROMs and battery and I change cable and battery keeps falling. And when to my brother drain 3% and to me drain 2x or more. What I need to do? Now I have Xeon ROM, before this I'll try fulmics ROM and stock ROM. And battery drain faster Always. And the problem with the charger started just a few days ago. And sometimes it works out, but it has reached the level that it charges 11% in half an hour(The Phone is Turn off) !!! Then I changed cable and it improved a bit, but still makes trouble
