Abstract
Various embodiments of systems, methods and apparatus are provided for adjusting a low battery detection threshold in a remote control. An embodiment of a method includes determining a type of a battery powering a remote control of an entertainment device and determining a first low battery threshold for the battery based on the type of the battery. The first low battery threshold indicates a low battery condition of the remote control. Responsive to measuring a voltage of the battery, a determination is made regarding whether the voltage of the battery is below the low battery threshold. Responsive to determining that the voltage of the battery is below the first low battery threshold, a low battery message is transmitted to an entertainment device. The entertainment device utilizes the message to present an indicator to a user regarding the low battery condition of the remote control.
