1. A system for conserving energy in a mobile communications device, comprising:

  • a mobile communications device;

    a low-power processor integral to the mobile communications device that is coupled to a primary processor of the mobile communications device via one or more data channels;

    a plurality of sensors switchably coupled to the low-power processor and the primary processor to directly interface the sensors with either the low-power processor or the primary processor based on the switching of the sensors;

    wherein the low-power processor receives and processes inputs from one or more of the sensors via one or more data channels while the mobile communications device is in a low-power state; and

    wherein the low-power processor stores inputs received from the one or more sensors in a memory device that is accessible to the primary processor of the mobile communications device via one or more data channels when the mobile communications device is not in a low-power state.
