aeh, first of all my mind is playing tricks and I could swear that "its
battery is being charged" was not in the isPlugged description so my comment
is void.

To answer your question (and leaving aside I am wrong about the isPlugged), in
the example[1] one uses isPlugged + charge level to change the polling
interval. My point was that just because I have a charger attached, doesn't
mean that the device is not emptying the battery (be it I do not have enough
current on the USB outlet, a USB hub...).

PS: "If the device is current plugged in" is needs probably a ly for the current.
