surely there might be a mistake in how data are parsed,
but remember that the "remaining time" is computed based
on remaining capacity and recent average current.
So, if for any reason (cpu/disk/network load decreases, screensaver,
etc.) the current decreases, the reported time goes up.
It happens all the time with 'acpiconf -i batt' even on 7.x.
