1. A user device comprising:

  • a display disposed at a front side of the user device;

    one or more antennas to transmit information;

    one or more sensors to detect a presence of a human body part, wherein the one or more sensors are at predetermined distances from the one or more antennas to detect the presence of the human body part within a proximity of the one or more antennas; and

    a power manager configured to reduce a power output of the one or more antennas when the presence of the human body part is detected, wherein a level of reduction for the power output of the one or more antennas is based on a combination of transmit power levels of two or more previous transmissions within a sample period, and wherein the two or more previous transmissions were made while the one or more sensors detected the human body part within the proximity of the one or more antennas.
