Hi, i use cm11 unofficial based on 4.4.4 android on my Galaxy grand dous, when i charge my mobile it take very long time yesterday it take 2 hours for 10% only (from 63% to 75%) any one knows what's the problem? Thanks.
Did you calibrate the battery after flashing a new ROM? Use a battery calibrator app to fix it up.
Plus dont charge with a USB cord, it'll take FOREVER for it to charge.
Instead use the offical samsung charger through a wall outlet for best results.
Hope this helps!
