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.
