    I have a strange problem with my phone gt-s7582 cm12.1 . first of all, I have battery drain sometimes from 15% to 0% and sometimes from 30% to 0% and not only in cm12.1 but also on the stock rom but this not the problem actually this OK for me. the strange problem is that I can't charge my phone to 100% at first I could only charge to 94% then after 2 days I could charge to 75% only and now I can't charge more than 60%. I have bought 2 batteries and the problem even with the stock rom . something else that when I change the battery I get the same battery %. so if now the phone says that the battery is 40% and I changed the battery it will give me 40%. please anyone tell me how can I solve these problems.
    all the previous problems is the same with the stock ROM so the problem is not in cm12.1

    Look up how to calibrate your battery for your device.

    I did that many times and it does nothing.
