A system and method for managing mobile communications device connectivity and communication behavior monitor device location relative to known communication-mode coverage areas and cause or suggest changes in device connectivity or behavior based on a power-drain map to preserve device battery power. The power-drain map provides, in an embodiment, a pairing of locations, available communication modes, and expected power drains when a given device employs each available communication mode. In general, behavioral modifications include preemptive or delayed downloading as well as switching networks or network types among other types of behavior. |

1. A method of creating a power-drain map for a wireless communications device, the power-drain map usable to modify a communications behavior of the communications device to reduce consumption of remaining battery power, the method comprising:
determining, by the wireless communications device, a current geographical location of the wireless communications device; measuring, by the wireless communications device, a power drain associated with wireless connectivity at the current geographical location related to a current communication mode in use by the wireless communications device, the power drain including a power drain per unit data during transmission or receipt of data; associating, by the wireless communications device, the measured power drain with the current geographical location and the current communication mode; and building, by the wireless communications device, the power-drain map, the power-drain map comprising the measured power drain, current communication mode, current geographical location, and information associated with a power-drain model for increasing drain of a battery of the wireless communication device, the power-drain map being usable by the wireless communications device to modify the communications behavior to reduce consumption of the remaining battery power. |
