Abstract

Techniques are described for dynamically changing a power draw from a power source of a portable device based on an audio output of the portable device. In an example, the portable device determines that an audio signal to be output by the portable device is associated with an audio mode. The portable device sets a voltage of a power converter of the portable device to a voltage level based at least in part on the audio mode. An amount of power is supplied from a power source of the portable device to the power converter based at least in part on the voltage level. In addition, the portable device outputs the audio signal based at least in part on the amount of power.
