1. A communication device comprising a processor configured to:
detect whether a body is proximately located based on obtained proximity sensor data;
define an upper threshold for a radio frequency (RF) transmit power and a lower threshold for the RF transmit power;
calculate an average power of an RF transmitter over a fixed time period; and
determine whether to apply or remove a power back-off to the RF transmitter based on whether the body is detected, the average power, and a comparison of the average power to the upper threshold or the lower threshold.
