Abstract

An electronic device is disclosed. The disclosed electronic device includes a display, a charging circuit that transmits and receives power to and from an external electronic device, a sensor circuit that senses a spatial relationship of the electronic device with the external electronic device, a processor that is electrically connected with the display, the charging circuit, and the sensor circuit. When wirelessly transmitting or receiving power to or from the external electronic device using the charging circuit, the processor may transmit and receive information associated with the wireless transmission or reception of power and display the information based on the spatial relationship.

First claim

What is claimed is:

1. An electronic device comprising:
a display;
a charging circuit configured to transmit and receive power to and from an external electronic device;
a sensor circuit and/or a camera configured to detect 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; and
a processor electrically connected with the display, the charging circuit, and the sensor circuit,
wherein, when wirelessly transmitting or receiving power to or from the external electronic device using the charging circuit, the processor is configured to:
transmit and receive information associated with the wireless transmission or reception of power; and
display the information if the electronic device is detected to be facing away from the surface.

2. The electronic device of claim 1 , 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.

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.
