An electronic device includes a battery, a plurality of capacitors, a converter that receives power from the battery and charges each of the plurality of capacitors to different voltages based on the power, a plurality of switches that switch a first path and a second path of each of the plurality of capacitors, and a controller. The controller selects a first switch among the plurality of switches based on a received signal, and controls the first switch such that a path of a capacitor connected to the first switch is switched from the first path to the second path, and the first path is a path which electrically connects each of the plurality of capacitors to the converter, the second path is a path which electrically connects each of the plurality of capacitors and a power amplifier (PA).
