I have the same concern, my bedroom keypad just glows at night, and is keeping us up. It should only be a matter of a firmware update.

When the unit is unplugged from the wall, both are out, but the status indicator comes on with a keypress. The battery indicator should do the same in both instances regardless if it plugged into the wall or not. Once it is a full charge, shut it off until a keypress.
