Dynamic duty-cycling of processor of mobile device based on operating condition of mobile device

DYNAMIC DUTY-CYCLING OF PROCESSOR OF MOBILE DEVICE BASED ON OPERATING CONDITION OF MOBILE DEVICE In one embodiment, a method includes recording a first location of a mobile device; determining, by one or more processors of a geographic-positioning component of the mobile device, on a periodic basis, a current location of the mobile device; 5 determining, by the processors of the geographic-positioning component, whether the current location is outside a geographic region defined at least in part by the first location; and if the current location is outside the geographic region, then transmitting, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or 0 more of the other processors to transition from a sleep state to an active state. 301 record, by a geographical positioning device coupled to a mobile device, a first location of the mobile device 302 determine a radius based on a velocity of the mobile device record a second location Is the second location beyond the radius from the first location? 304 transmit a message to one or more processors of the mobile device
