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.

Electronic device including a power management integrated circuit (PMIC) and operating method thereof

An example electronic device includes a communication processor; at least one radio frequency integrated circuit (RFIC) connected to the communication processor; at least one radio frequency front-end (RFFE) circuit connected to the at least one RFIC and configured to process a transmission signal; and a plurality of antennas connected through the at least one RFFE circuit. The communication processor may control to transmit, at a first time point when a reference signal is to be transmitted through a first antenna from among the plurality of antennas, the reference signal to a base station through the first antenna; and transmit, at a second time point when the reference signal is to be transmitted through a second antenna from among the plurality of antennas, a reference signal adjusted at least based on a signal received through the second antenna to the base station through the first antenna.
