3. The electronic device of claim 1 , wherein the displayed information includes information generated by the electronic device and information received from the external electronic device.
4. The electronic device of claim 1 , wherein a first frequency used to wirelessly transmit or receive power is different from a second frequency used to transmit and receive the information.
5. The electronic device of claim 1 , wherein the processor is further configured to not display the information if the electronic device is detected to be facing toward the surface.
6. The electronic device of claim 1 , wherein, if the electronic device transmits power to the external electronic device, the processor is further configured to execute only a pre-defined application.
7. The electronic device of claim 1 , wherein, if the electronic device transmits power to the external electronic device, the processor is further configured to enter a low-power mode to execute only one or more pre-defined functions.
8. The electronic device of claim 1 , wherein, if the electronic device transmits power to the external electronic device, the processor is further configured to display, in the display, a first user interface displaying at least one of a current power capacity of the electronic device, a target capacity remaining after the wireless transmission of power is completed, a progress indicator, and an estimated time remaining for the wireless transmission of power.
9. The electronic device of claim 1 , wherein, if the electronic device receives power from the external electronic device, the processor is further configured to display, in the display, a second user interface displaying at least one of a current power capacity of the external electronic device, a target capacity remaining after the wireless transmission of power is completed, and an estimated time remaining for the wireless transmission of power.
10. The electronic device of claim 9 , wherein the processor is further configured to adjust the target capacity based on an input from a user.
11. A control method of an electronic device including a display, the method comprising:
wirelessly transmitting or receiving power to or from an external electronic device;
detecting whether the electronic device is facing away from a surface such that the display is visible to a user or facing toward the surface such that the display is obscured from the user by the surface;
transmitting and receiving information associated with the wireless transmission or reception of power; and
displaying the information if the electronic device is detected to be facing away from the surface.
12. The method of claim 11 , wherein the information includes at least one of a battery level of the electronic device, an amount of power consumed by the electronic device, a temperature of the electronic device, when the wireless transmission or reception of power started, an estimated time for completing the wireless transmission or reception of power, a charging current of the electronic device, and time elapsed since a start of the wireless transmission or reception of power.
13. The method of claim 11 , wherein the displayed information includes information generated by the electronic device and information received from the external electronic device.
14. The method of claim 11 , wherein the method includes:
not displaying the information if the electronic device is detected to be facing toward the surface.
15. The method of claim 11 , wherein, if the electronic device transmits power to the external electronic device, the method further comprises:
executing only a pre-defined application.
16. The method of claim 11 , wherein, if the electronic device transmits power to the external electronic device, the method further comprises:
entering a low-power mode to execute only one or more pre-defined functions.
17. The method of claim 11 , wherein, if the electronic device transmits power to the external electronic device, the method further comprises:
displaying, in the display, a first user interface displaying at least one of a current power capacity of the electronic device, a target capacity remaining after the wireless transmission of power is completed, a progress indicator, and an estimated time remaining for the wireless transmission of power.
18. The method of claim 11 , wherein, if the electronic device receives power from the external electronic device, the method further comprises:
displaying, in the display, a second user interface displaying at least one of a current power capacity of the external electronic device, a target capacity remaining after the wireless transmission of power is completed, and an estimated time remaining for the wireless transmission of power.
19. The method of claim 18 , wherein the method includes:
adjusting the target capacity based on an input from a user.
20. A recording medium storing instructions for an electronic device including a display, the instructions, when executed by a processor of the electronic device, perform a method of:
wirelessly transmitting or receiving power to or from an external electronic device;
detecting whether the electronic device is facing away from a surface such that the display is visible to a user or facing toward the surface such that the display is obscured from the user by the surface;
transmitting and receiving information associated with the wireless transmission or reception of power; and
displaying information if the electronic device is detected to be facing away from the surface.
