Abstract: Various embodiments related to electronic devices are set forth herein. According to an embodiment, an electronic device comprises a coil, a power transmitting circuit electrically connected with the coil, a sensing circuit, and a control circuit. The control circuit is configured to wirelessly output, using the power transmitting circuit, a first designated power through the coil to an external electronic device, and identify, using the sensing circuit, first energy detected at the coil due to a foreign object of the electronic device. The control circuit is further configured to, when a magnitude of the energy falls within a first designated range, output, using the power transmitting circuit, a second designated power to the external electronic device, and when the magnitude of the energy falls within a second designated range, abstain from outputting the power to the external electronic device using the power transmitting circuit. Other embodiments are possible as well.
