Abstract: An electronic device is provided. The electronic device includes a charging circuit, a battery, and a processor operatively connected to the charging circuit and the battery, wherein the processor is configured to charge the battery with a first voltage corresponding to a first charging level, identify the number of times that supplementary charging is performed after the electronic device is detected to be in a fully-charged state, when the number of times that the supplementary charging is performed exceeds a specified number of times, configure a charging level for charging the battery to a second charging level configured to be lower than the first voltage of the first charging level, and adjust a voltage received from a power transmission device through the charging circuit to a second voltage corresponding to the second charging level and charge the battery with the adjusted second voltage.
