Abstract
There is a need to provide an intuitive way for a battery-powered device to send a low battery notification to another device that can properly notify a user that the battery-powered device has a low battery. The user can be notified by the other device even after the battery-powered device has exhausted its battery to the point where it can no longer report its battery state. A second electronic device (e.g., a remote control) can send a low battery notification to a first electronic device (e.g., a set-top box) so that the first electronic device can alert a user that the second electronic device has a low battery.
