Abstract
A mobile device, e.g. a remote control, that communicates with a remote device. The device is controlled by a battery providing power for electronic circuits and components contained within the hand held remote control device. A battery monitoring device measures the voltage of the battery. A memory device saves the data generated by the battery monitoring device indicating the voltage of the battery. A transmission device transmits a notification to the display device when the voltage of the battery decreases to some predetermined level. The display device may receive the notification of a low battery from the hand held device. An application contained within the display device or the remote control displays a visual indication on the display device to the user indicating that the battery in the hand held device is low and requires recharging.
