Avoiding battery depletion of a mobile device

摘要

A method of regulating the battery usage of a wireless device includes receiving information indicating the battery charge level of a wireless device over a first wireless communication channel using a short-range wireless communication protocol; choosing a wireless communication protocol for use by the wireless device with a second wireless communication channel based on the received battery charge level information; constructing a message instructing the wireless device to use the chosen wireless communication protocol for communications via the second wireless communication channel; and sending the message from a vehicle telematics unit to the wireless device.
