Abstract: An electronic device is provided. The electronic device includes: a first processing unit; a storage unit, configured to store at least one audio file; a first memory unit; and a modulator-demodulator (modem), configured to perform audio processing of the electronic device during a phone call, wherein when the electronic device is used to play the audio file, the first processing unit reads the audio file from the storage unit, retrieves header information of the audio file, and writes the audio file into the first memory unit, wherein the modem accesses the audio file stored in the first memory unit based on the header information, and performs audio decoding on the audio file.

Abstract: A power-management method is provided, and the power-management method includes setting a central processing unit in a first low-power state when receiving a second low-power state request requiring the central processing unit to enter the second low-power state, obtaining first idle periods of the peripheral modules respectively to determine a second idle period according to the first idle periods of the peripheral modules, determining whether the peripheral modules have not sent a data-access request during the second idle period, setting the central processing unit in the second low-power state when the peripheral modules have not sent the data-access request during the second idle period, wherein each first idle period is an interval period between two data transmissions of each peripheral module.
