I have a nano clone with that firmware, and it was showing half battery after a full charge. Fortunately, it came to its senses and is now showing full.... :)

Is there only one version of that firmware? I don't trust the version number, as it doesn't make sense that different chipsets would run the same firmware.

Hi, Levemente!

The charger that came with my player does not fully charges battery. I´ll try to fix that changing some electronic components.

If I use my home computer's USB, battery does not charge either.
But at office it works fine.
Both computers are a little bit old, USB 1.x, but it seems that some old USB ports are not able to give enough power.
Maybe that's your case. Try another computer, and even another cable (a friend of mine is got cable issues)

Bye!
