Abstract
Various embodiments are directed to systems and techniques for reducing power consumption in a mobile computing device. In one or more embodiments, a mobile computing device may be arranged to determine a user environment based on detected antenna impedance or detected current. After the user environment is determined, the mobile computing device may confirm that total radiation power (TRP) for the mobile computing device at an initial conducted power level exceeds the minimum TRP threshold required by the network carrier to receive acceptable quality of service (QoS). Based on the excess TRP for the particular user environment, the mobile computing device may determine a reduced conducted power level to be input to an antenna system. Accordingly, significant power savings may be achieved. To save additional power, the mobile computing device may automatically adjust and/or improve antenna impedance matching based on user environment allowing a further reduction in conducted power. Other embodiments are described and claimed.
