1. An electronic device comprising:
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;
a capacitor electrically connected to an output terminal of the regulator; and
a processor electrically connected to the wireless communication circuit, the battery, and the PMIC,
wherein the processor is configured to, responsive to the electronic device satisfying a specified condition,
identify a change in a magnitude of a voltage of the output terminal of the regulator for a first time interval,
identify a ratio of a third 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, during a second time interval following the first time interval, a voltage of the output terminal in a step-wise manner based on the ratio,
wherein the capacitor is charged or discharged based on the adjusted voltage.
