1. A method comprising:detecting a specific absorption rate (SAR) trigger at a mobile computing device indicative of potential for non-compliance with SAR legal limits;
determining current signal conditions of the mobile computing device, the current signal conditions including a current radio-frequency (RF) transmission power of one or more antennas of the mobile computing device for communicating with one or more base stations;
predicting future signal conditions of the mobile computing device using a prediction model, the prediction model including a predicted RF transmission power for maintaining the communication of the one or more antennas of the mobile computing device with the one or more base stations over a future period of time and for satisfying the SAR legal limits over the future period of time, the prediction model configured to derive a predicted change over the future period of time in a received signal strength indicator (RSSI) detectable at the one or more base stations based on analysis of historical usage data for the mobile computing device; and
adjusting the RF transmission power of the one or more antennas of the mobile computing device a selected amount in response to detecting the SAR trigger, the selected amount based on the determined current signal conditions and the predicted future signal conditions.
