So the Battery itself could have powered the device for some extra time, and it is not completely drained on the hanging event.
An e-ink screen does not need power to retain its information. So if you cut of the power, the last information on the screen will stay there.

Although the screen was still showing the last page which was loaded before the hang-up, I could not reset it through the reset switch on the bottom. It needed a recharger to be plugged in before it can start again. I am not complaining though, I have got nearly 13 hours of continuous use and even with the annoying hang-up on the end, the device is much more useful than with a nearly dead Varta on board.
Thanks for the tips on replacing the battery Guys.
Normally the battery charger/monitor needs to 'learn' how the battery behaves, so it is possible that after a few charge/use cycles the indication of the power left in the battery will be more accurate. But then it could also be that some special parameters need to be configured in the charger-chip to match the used battery, time will tell.
