Isn't what you want to use the current battery level? It doesn't really
matter whether a battery is charging or not if the current battery level is
low because the user might decide to unplug the device as soon as you
started downloading something, in which case, the device can power off if
the batter level is low.

I'd argue that isPlugged should be false in such a case.
