Abstract: An electronic device may include a wireless communication circuit, a battery, a power management integrated circuit (PMIC) electrically connected to the wireless communication circuit and the battery and including a regulator, and a processor electrically connected to the wireless communication circuit, the battery, and the PMIC. The processor may, responsive to the electronic device satisfying a specified condition, identify a change in a magnitude of a voltage of an output terminal of the regulator for a first time interval, identify a ratio of a time interval during which the change in the magnitude of the voltage of the output terminal satisfies a threshold value with respect to the first time interval, and adjust the magnitude of the voltage of the output terminal in a step-wise manner based on the ratio.

Abstract: 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).
