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.
