Abstract

A method and apparatus for providing information about a plurality of wireless charging pads to an electronic device such that the electronic device performs wireless charging efficiently is provided. The method includes receiving information about the plurality of wireless charging pads and displaying the information about the plurality of wireless charging pads on a screen of the electronic device.

Claims

1. A method displaying information about a wireless charging pad in an electronic device, the method comprising:

connecting to the wireless charging pad and starting wireless charging;

calculating a wireless charging efficiency while starting the wireless charging, the calculating of the wireless charging efficiency comprising comparing an orientation of the wireless charging pad with an orientation of a side surface of the electronic device; and

outputting a result corresponding to the calculated wireless charging efficiency,

wherein outputting the result comprises displaying an X-axis, Y-axis, and Z-axis with an orientation of the electronic device according to the X-axis, Y-axis, and Z-axis that obtains a maximum wireless charging efficiency.

2. The method of claim 1,

wherein the wireless charging efficiency is further calculated by a difference between an entire wireless charging efficiency and a battery consumption amount of the electronic device, and

wherein the entire wireless charging efficiency is further calculated by a ratio of an output power and an input power of the wireless charging pad.

3. The method of claim 1, wherein the outputting of the result corresponding to the calculated wireless charging efficiency comprises:

determining a lamp color according to the wireless charging efficiency; and

operating a lamp to emit the lamp color.

4. The method of claim 1, wherein the output of the result corresponding to the calculated wireless charging efficiency comprises:

converting the result corresponding to the calculated wireless charging efficiency into an indicator, a text, or a voice; and

outputting the converted indicator, the text, or the voice.

5. An electronic device comprising:

one or more processors;

a memory having one or more programs, each of the one or more programs being configured to be executed by the one or more processors,

wherein a program of the one or more programs, when executed by the one or more processors, includes instructions that;

connect to the wireless charging pad,

calculate a wireless charging efficiency while the electronic device performs wireless charging, and

output a result corresponding to the calculated wireless charging efficiency,

wherein the instruction that calculates the wireless charging efficiency includes an instruction that compares an orientation of the wireless charging pad with an orientation of one side surface of the electronic device, and

wherein the instruction that outputs the result includes an instruction that displays an X-axis, Y-axis, and Z-axis with an orientation of the electronic device according to the X-axis, Y-axis, and Z-axis that obtains a maximum wireless charging efficiency.

6. The electronic device of claim 5,

wherein the wireless charging efficiency is further determined by difference between an entire wireless charging efficiency and a battery consumption amount of the electronic device, and

wherein the wireless charging efficiency is further determined by a ratio of an output power and an input power of the wireless charging pad.

7. The electronic device of claim 5, wherein the instruction that outputs the result corresponding to the calculated wireless charging efficiency includes an instruction that determines a lamp color according to the wireless charging efficiency and operates a lamp to emit the lamp color.

8. The electronic device of claim 5, wherein the instruction that outputs the result corresponding to the calculated wireless charging efficiency includes an instruction that converts the result corresponding to the calculated wireless charging efficiency into an indicator, a text, or a voice and outputs the converted indicator, the text, or the voice.

9. The electronic device of claim 5, wherein the instruction that outputs the result corresponding to the calculated wireless charging efficiency further includes an instruction that displays a graphic showing an orientation of the electronic device in correspondence to the orientation of the wireless charging pad.
