1. A wireless charging method in a portable electronic device, the method comprising:
- connecting wirelessly the portable electronic device with a wireless power supply device;
connecting the portable electronic device with at least one external device;
monitoring charging efficiency of a device being charged by the wireless power supply device;
when the charging efficiency is either equal to or smaller than a given first threshold, identifying a distance between the wireless power supply device and the device being charged; and
when the distance is either equal to or greater than a given second threshold, outputting a notification for indicating a need of movement;
wherein the portable electronic device is configured to supply electric power to the at least one external device, when the portable electronic device has a battery charging percentage greater than a given threshold.
