a control circuit electrically connected to the fan and the wireless charging circuit, and configured to:

receive, from the external device, a signal for indicating that a first charge based on a first power or a second charge based on a second power is requested from the external device,

based on the signal, control the wireless charging circuit to wirelessly transmit the first power or the second power to the external device via the wireless charging coil, and

control, based on the transmitted first or second power, the fan by performing at least one of turning on the fan, turning off the fan, or changing a rotation speed of the fan,

wherein the second power is greater than the first power.

2. The electronic device of claim 1 ,

wherein the control circuit is further configured to:

control the fan to rotate at a second speed in response to transmitting the second power to the external device, and

control the fan to rotate at a first speed in response to transmitting the first power to the external device, and

wherein the second speed is higher than the first speed.

3. The electronic device of claim 1 ,

wherein the wireless charging circuit is configured to operate in a first mode for transmitting the first power or a second mode for transmitting the second power, and

wherein the control circuit is further configured to select the first mode or the second mode based on at least one of the signal.

4. The electronic device of claim 3 , wherein the control circuit further comprises a circuit configured to receive power of a different level from an external power source based on the first mode or the second mode.

5. The electronic device of claim 1 , wherein the control circuit is further configured to receive a control signal including an indication for requesting control of the fan from the external device via the wireless charging circuit.

6. The electronic device of claim 5 , wherein the control circuit is further configured to control an operation of the fan based on the received control signal.

7. The electronic device of claim 1 , further comprising:

a temperature sensor configured to detect a temperature inside the housing.

8. The electronic device of claim 7 , wherein the control circuit is further configured to receive data indicating the temperature inside the housing from the temperature sensor.

9. The electronic device of claim 8 , wherein the control circuit is further configured to control an operation of the electronic device based on the received data.

10. The electronic device of claim 8 , wherein the control circuit is further configured to control the fan based on the received signal and the received data.

11. The electronic device of claim 1 , wherein the control circuit is further configured to:

obtain information on a time when wireless charging to be performed, and

control the wireless charging circuit to wirelessly transmit a preset power of a default charging mode to the external device through the wireless charging coil in response to the time being within a pre-determined time period.

12. The electronic device of claim 10 , wherein in response to the time indicating a nighttime, the control circuit is further configured to control the fan based on the default charging mode.

13. The electronic device of claim 1 , wherein in response to receiving a charging complete signal indicating that a battery of the external device is fully charged from the external device, the control circuit is further configured to control the wireless charging circuit to stop wirelessly transmitting a power and/or turn off the fan.

14. A method for performing wireless charging in an electronic device, the method comprising:

receiving, from an external device, a signal for indicating that a first charge based on a first power or a second charge based on a second power is requested from the external device;

based on the signal, wirelessly transmitting the first power or the second power to the external device via a wireless charging coil included in the electronic device; and

controlling, based on the transmitted first or second power, a fan included in the electronic device by performing at least one of turning on the fan, turning off the fan, or changing a rotation speed of the fan,

wherein the second power is greater than the first power.

15. The method of claim 14 , further comprising:

controlling the fan to rotate at a second speed in response to transmitting the second power to the external device, and

controlling the fan to rotate at a first speed in response to transmitting the first power to the external device,

wherein the second speed is higher than the first speed.

16. The method of claim 14 , wherein the controlling of the fan comprises receiving a control signal including an indication for requesting control of the fan from the external device via a wireless charging circuit.

17. The method of claim 16 , further comprising:

controlling an operation of the fan based on the received control signal.

18. The method of claim 14 , further comprising:

obtaining information on a time when wireless charging to be performed; and

wirelessly transmitting a preset power of a default charging mode to the external device through a wireless charging coil including the wireless charging coil in response to the time being within a pre-determined time period.

19. The method of claim 14 , further comprising:

in response to a time indicating a nighttime, controlling the fan based on a default charging mode.

20. The method of claim 14 , further comprising:

in response to receiving a charging complete signal indicating that a battery of the external device is fully charged from the external device, stopping wirelessly transmitting a power and/or turning off the fan.

21. The method of claim 14 , further comprising:

receiving data indicating a temperature inside the electronic device, from a temperature sensor of the electronic device.
