Hmmm... well, I'm on the latest firmware 1.9.9, and it has happened to me since then.
The first time, admittedly, was on an earlier version of the firmware.
And @Scion: same thing happened to me; showed fully charged in less than 15 minutes.
I guess I'll try the 3 hour charge or the overnight charge next time. If there is a next time. (Crosses fingers that there *won't* be a next time).
