Mobile wireless communications device with proximity based transmitted power control and related methods

A mobile wireless communications device comprising:

• a display carried by said portable housing;
• a plurality of antennas carried by said portable housing;
• a plurality of capacitive proximity sensors adjacent corresponding ones of said plurality of antennas and carried by said portable housing, and each configured to sense proximity of a human user adjacent thereto, at least one of said plurality of capacitive proximity sensors on said display;
• a wireless transmitter carried by said portable housing and coupled to said plurality of antennas;
• and
• a controller carried by said portable housing and coupled to said wireless transmitter, said display, and said plurality of capacitive proximity sensors, and configured to cooperate with said wireless transmitter to adjust transmitted power output from said plurality of antennas based upon said plurality of capacitive proximity sensors.

A method of adjusting transmitted power output from a plurality of antennas of a mobile wireless communications device comprising a portable housing carrying the plurality of antennas, a respective capacitive proximity sensor coupled to each of the plurality of antennas, a wireless transmitter coupled to the plurality of antennas, and a controller coupled to the wireless transmitter and the capacitive proximity sensors, the method comprising:

• using the capacitive proximity sensors to sense proximity of a human user adjacent thereto;
• and
• using the controller to
• cooperate with the wireless transmitter to adjust transmitted power output at each of the plurality of antennas based upon its respective capacitive proximity sensor, and
• adjust the transmitted power output at each of the plurality of antennas to a reduced power level based upon sensing the human user immediately adjacent at least one of the capacitive proximity sensors.
