a battery management system configured to:
monitor a state parameter of the battery; and
communicate the state parameter of the battery to a processor that is electrically coupled to the battery;
wherein the processor is configured to:
responsive to determining that a power level of the first power falls below a threshold value:
communicate with the battery to provide the second power; and
activate a low power mode of the media device;
detect an event while in the low power mode;
