Abstract: A method and electronic device for performing wireless charging are provided. The electronic device includes a housing, a conductive coil, a power transmission circuit electrically connected to the conductive coil, and configured to wirelessly transmit power to an outside of the housing through the conductive coil, a voltage source electrically connected to the power transmission circuit, and a control circuit electrically connected between the power transmission circuit and the voltage source. The control circuit is configured to change power radiated through the conductive coil, monitor a frequency of a signal and/or electromagnetic waves radiated through the conductive coil, and adjust a level of a voltage from the voltage source based on at least a part of a monitored result of the frequency.

Abstract: An electronic device and a method for sensing moisture in an electronic device are provided. The method for sensing moisture in an electronic device includes sensing moisture introduced into a connector of the electronic device in a state where one or more functions executable by connection of the connector with an external electronic device are activated. Further, the method includes deactivating the one or more functions based on the sensing; determining whether the introduced moisture is removed in a state where the one or more functions are deactivated; and activating the one or more functions if the moisture is removed.
