It is not my problem; it is HAL problem :)

As I already asked in another reply - how do you calculate 100%? You assume that 
last_full is going to be always reached. That is not correct. In my case 
charging stops before. While this means degraded battery, it is still charged up 
to 100% of new (degraded) capacity.

While this condition warrants some sort of warning to user, it is probably wrong 
to indefinitely claim "battery is charging" when in fact it is not.

So far all information I got from HAL was correct.
