Both with USB and my external charging i reach 95-100% so that 80% limit is not whats wrong.

You missed something in the OP. He said that he can't charge over 80% when plugging the charger, not always. That is, if the battery is over a certain percentage, you can't start a cycle, but charging definitely goes over 80%.
Also, I think it's not 80%, it's 80-something or it's tied to voltage, capacity or something because it's not constant AFAICT. Still, fact remains, if battery is high enough (but not completely full) it will refuse to charge with the message "battery full".
To start a charge cycle, one needs to discharge the battery under a percentage that is close to 80 something. Also, high-drain apps will tend to push percentage lower than it actually is. Very high drain will drop percentage under 80% in a minute or so.
Oh, also, percentage is calculated by several factors, including voltage, and is an estimate based on drain (droop), not a direct correlation. That's why it sometimes goes up. As a result, percentage can be up or down not only based on voltage, but on other factors. As a result, 80% is not 4.00V, since if it is 4.2 but drain is high it will show 80%. Stop draining and it climbs back up.
I've had as much as 20% delta between real capacity and percentage reported.
Mine stops charging at 96%.

Correct.

Thank you for your answers. The situation is getting worse. After unplugging the device from the charger it thinks charcing continues. Led is blinking as well.
WTF?
Battery and charger are both Nokia's.

I have two battery widgets: joppus's battery widget and dr_frost_dk's battery meter -qbw. Both of them works. I cannot see that they have any influence to the problem.
I cannot identify what could be causing the problem. One solution could be resetting the stock battery indicator from terminal, but I don't know the command.
My N900 was just just replaced to a new one. Any ideas where the problem could be related? For first aid could someone please tell me the command to reset the indicator.
