Abstract
An electronic device and method are disclosed. The electronic device includes: a battery, a wireless power transfer (WPT) coil, wireless power transceiver circuitry, a charging circuit, and a processor electrically connected to the wireless power transceiver circuitry and the charging circuit. The processor implements the method, including: receiving first detecting power from an external electronic device, determining whether a reception voltage generated by the received first detecting power is higher than a first predetermined voltage value, based on detecting that the reception voltage is higher than the first predetermined voltage value, supplying power from the battery to the wireless power transceiver circuitry, outputting via the WPT coil, foreign object detecting power based on the supplied power, and based on detecting an electrical change in the foreign object detecting power caused by presence of a foreign object, determining that an error has occurred.
