Abstract: Devices and methods for power management during media playback are provided. For example, an electronic device according to an embodiment may include storage, a decoder, an output buffer, and data processing circuitry. The storage may store compressed media data that may be decoded by the decoder. The output buffer may store the decoded media data before the decoded media data is played out. The data processing circuitry configured may measure a fullness of the output buffer and may set an operating frequency of the storage, the decoder, the output buffer, or the data processing circuitry, or a combination thereof, depending on a format of the compressed media data and the fullness of the output buffer.

Abstract: Various techniques that relate to prolonging the battery life on a portable electronic device during the buffering and playback of audio broadcast data are provided. In accordance with disclosed embodiments, upon detecting a low power state, the device may implement one or more low power actions, including starting, continuing, or stopping one or more audio broadcast functions, such as buffering or playing back audio broadcast data, to reduce overall power consumption, and thus prolong battery life. In one embodiment, a user may specify one or more low power actions that are to be implemented during a low power state by configuring user settings stored on the device. In another embodiment, the device, upon detecting a low power state, may prompt the user to make a selection from a listing of selectable low power action options and perform the selected low power action.
