Yesterday, I charged my Gopro Session when it was powered off and the battery charge was ok (it took 1,5 hours aprox). Moreover, the battery was working during 2 hours recording without any problem.
So, if GoPro session is powered off, the charge process works correctly, but if GoPro is powered on, the charge process does not works well: in my case, when GoPro is On, it diplays battery full at half an hour charging (which it is incorrect) and stops charging. I understand this is a firmware bug, but with this workaround it is enough.
