[Power/Battery] Missing Battery Capacity

My apologies for creating a new thread. I'm a new user and had issue posting an answer to the original thread.

Hi All,

I had the same issue with my phone where I'm losing around 1200+.
I charged my phone using my Nexus 7's charger and it somehow resolved the issue. I charge it from 40% to full and it now shows 2900+.
It might be with the excessive used of quick charging.
