When a device such as a smart phone provides directions to a destination, use of the device's GPS transceiver to output the directions can drain the device's battery undesirably fast. As recognized herein, this can be frustrating to a user because the drain on the battery can leave the device without enough battery power to execute other tasks and because the battery may run out of power before another opportunity to charge it arises. There are currently no adequate solutions to the foregoing computer-related, technological problem.
