For example, in a situation where the battery 189 is charged using a set charging voltage and a set charging current, a charging frequency representing optimal charging efficiency may be set in advance. For example, when the charging voltage and charging current are set to specific values, charging efficiency for the battery 189 may be determined based on the charging frequency. For example, charging-related information 320 may include charging voltage, charging current, and/or charging frequency.

For example, the second charging frequency may include a charging frequency with relatively lower charging efficiency than the first charging frequency. According to one embodiment, the second charging efficiency of charging the battery 189 based on the second charging frequency is relatively about 10% compared to the first charging efficiency of charging the battery 189 based on the first charging frequency. It can be reduced by as much as 0.15%. Using Equation 1 below, the relative reduction in charging efficiency (e.g. Path loss value) can be calculated.

It may be in a state of performing . According to one embodiment, when about 15W fast charging is performed based on the first charging frequency, the inductor included in the charging circuit (e.g., the charging circuit 310 of FIG. 3) of the electronic device 101 (e.g., Physical vibration may occur in the inductor 311 of 3). For example, the physical vibration generated through the inductor 311 is transmitted to a printed circuit board (PCB) on which the inductor 311 is placed, and may also be transmitted to the motion sensor 330 disposed on the printed circuit board. . Like the second section 712 in FIG. 7 , the motion sensor 330 may measure the first sensing value 731 based on the physical vibration generated through the inductor 311.

For example, the second charging frequency may be a charging frequency that has relatively lower charging efficiency than the first charging frequency. According to one embodiment, the electronic device 101 may check the first sensing value 731 through the motion sensor 330 while performing fast charging at about 15W based on the first charging frequency.
