[Q] HELP! Galaxy SII running out the battery with 40% charge
Hello guys I'm new here and would like some help with my Galaxy SII.
The problem is this: I am using the CM11 ROM 4.4.2 (also happened with the official) and the battery on my phone just ends when it reaches 40%, the screen in a blink on and off and only back to work when I connect my charger, the screen showing 0% battery, thereafter, he usually carries up to 100% more then the same happens again in 40%.
I've tried to calibrate and reset the fuel gauge chip, but it still fails if anyone has an idea I would be grateful.
Thanks in advance.
Note:. If I unplug the charger with less than 40% while charging the phone normally functions to 0%.
