description An electronic device and method are provided for frequency interference cancellation. The electronic device includes a coil, a wireless power receive circuit, a charging circuit, a display, and a processor. The processor may be configured to perform wireless charging with power wirelessly received from a wireless charger, change, via the charging circuit, a charging current of the electronic device from an initial current level to a first current level, based on the display being switched on during wireless charging, change, via the wireless power receive circuit, a charging voltage of the electronic device from an initial voltage level to a first voltage level, transmit, via the coil, a packet for changing a charging voltage of the wireless charger, change, via the wireless power receive circuit, the charging voltage of the electronic device to a second voltage level upon transmission of the packet, and change the charging current to the initial current level.
