In one illustrative example, a mobile communication device has a wireless transceiver; an antenna coupled to the wireless transceiver; one or more processors coupled to the wireless transceiver; and a power source interface which is adapted to connect with a power source for supplying electrical power to the mobile device. The one or more processors are operative to monitor a quick paging channel of a wireless communication network with use of the wireless transceiver; identify whether a predetermined power source is connected to the power source interface; cause an indication to terminate use of the quick paging channel to be transmitted with the wireless transceiver to the wireless network based on identifying that the predetermined power source is connected to the power source interface; and refrain from monitoring the quick paging channel with the wireless transceiver after sending the indication to the wireless network. In one specific implementation, the mobile device delays for a time period until a message used for registration is sent to the wireless network and provides the indication within this message.
