Abstract

An electronic device for performing a charging is provided. The electronic device includes a charging module configured to receive power to perform a charging, a communication module configured to communicate with at least one other electronic device, and a processor configured to determine power to be received, based on a signal quality of a communication signal that is received in the communication module, and control the charging module to receive the determined power.

Claims

1. An electronic device for performing a charging, the electronic device comprising:

a charging module configured to receive power to perform the charging;

a communication module configured to communicate with at least one other electronic device; and

a processor configured to;

determine power to be received, based on a signal quality of a communication signal that is received by the communication module, and

control the charging module to receive the determined power.

2. The electronic device of claim 1, wherein the processor is further configured to determine the power to be received based on association information between the signal quality of the received communication signal and the received power.

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

a memory configured to store a first threshold to determine whether the signal quality of the received communication signal is poor,

wherein, if the signal quality of the received communication signal is determined to be less than the first threshold, the processor is further configured to reduce the received power to be lower than a predetermined power.

4. The electronic device of claim 3,

wherein the charging module comprises:

a battery; and

a power management integrated chip (PMIC) configured to transfer the received power to the battery, and

wherein the processor is further configured to reduce the power that is transferred from the PMIC to the battery.

5. The electronic device of claim 3, wherein the processor is further configured to reduce the received power to a predetermined value.

6. The electronic device of claim 3, wherein the processor is further configured to reduce the received power until the signal quality of the received communication signal becomes greater than, or equal to, the first threshold.

7. The electronic device of claim 3, wherein the processor is further configured to reduce the received power based on association information between the signal quality of the received communication signal and the power to be reduced.

8. The electronic device of claim 3,

wherein the memory is further configured to store a second threshold to determine whether the signal quality of the received communication signal is good, and

wherein, if the signal quality of the received communication signal exceeds the second threshold, the processor is further configured to return the received power to a predetermined power.

9. The electronic device of claim 8, wherein the second threshold is greater than the first threshold.

10. The electronic device of claim 9, wherein the processor is further configured to perform the returning of the received power to the predetermined power from a reduction state of the received power in a hysteresis operation.

11. The electronic device of claim 1, wherein the processor is further configured to determine whether at least one communication signal for performing a communication is received during the performing of the charging.

12. The electronic device of claim 11, wherein the processor determines whether the at least one communication signal for performing a communication is received during the performing of the charging based on whether one of energy and received signal strength indication (RSSI), which is detected by the communication module, exceeds a threshold.

13. A control method of an electronic device for performing a charging, the method comprising:

receiving power to perform the charging;

communicating with at least one other electronic device;

determining power to be received, based on a signal quality of a communication signal that is received through the communicating with the at least one other electronic device; and

controlling the electronic device to receive the determined power.

14. The method of claim 13, wherein the determining of the power to be received comprises determining the power to be received based on association information between the signal quality of the received communication signal and the received power.

15. The method of claim 13,

wherein the determining of the power to be received comprises, if the signal quality of the received communication signal is determined to be less than a first threshold, reducing the received power to be lower than a predetermined power, and

wherein the first threshold determines whether the signal quality of the received communication signal is poor.

16. The method of claim 15, wherein the determining of the power to be received comprises reducing the received power to a predetermined value.

17. The method of claim 15, wherein the determining of the power to be received comprises reducing the received power until the signal quality of the received communication signal becomes greater than, or equal to, the first threshold.

18. The method of claim 15, wherein the determining of the power to be received comprises reducing the received power based on association information between the signal quality of the received communication signal and the received power.

19. The method of claim 15,

wherein the determining of the power to be received comprises, if the signal quality of the received communication signal exceeds a second threshold, returning the received power to a predetermined power, and

wherein the second threshold determines whether the signal quality of the received communication signal is good.

20. An electronic device for performing a charging, the electronic device comprising:

a charging module configured to receive power to perform the charging;
