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.
