A communication system may include a plurality of near-field communication (NFC) sensors each associated with a respective location, and a mobile wireless communications device(s) switchable among a plurality of different power consumption modes. The mobile wireless communications device(s) may include a portable housing, an NFC circuit carried by the housing and configured to establish NFC communications with at least one of the NFC sensors when in proximity therewith, and a plurality of different wireless communications circuits carried by the housing. The mobile wireless communications device(s) may further include a controller carried by the housing and coupled to the NFC circuit and the different wireless communications circuits which may be configured to switch to a given power consumption mode based upon the at least one NFC sensor. In particular, some of the different power consumption modes may be associated with selectively powering respective ones of the wireless communications circuits.

Communication system providing context-based mobile wireless communications device power consumption management and related methods

A wireless communications system includes a wireless communications network and a plurality of wireless communications devices. The wireless communications devices are each configured to communicate via the wireless communications network. At least one of the plurality of wireless communications devices has a portable housing, a wireless transceiver carried by the portable housing, and a wireless-based, availability detector carried by the portable housing. A processor is carried by the portable housing and is configured to determine a first availability status based upon the NFC device at a first time. The processor is further configured to activate the wireless-based, availability detector based upon the NFC device to thereby determine a second availability status based upon the wireless-based, availability detector at a second time after the first time. The processor is additionally configured to communicate the first and second availability status to the wireless communications network via the wireless transceiver.
