It starts showing that battery is full when it's actually not. If I unplug it and plug in again, it continues charging for a couple of hours more, then shows that battery is full and sign Charging goes off. I unplug it and plug again, and charging continues, and I can do it endlessly, and never know for sure if it's charged. Not sure if charging stops when icon Charging goes off or it's just fancy animation. Very annoying.
