Electronic device and method for transmitting information to external device for adjusting wireless power to be transmitted from external device on basis of proximity of external object

A device for wirelessly transmitting power, the device comprising:

• a communication module;
• a wireless charging module;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• transmit a signal related to wireless charging through the communication module,
• receive, from an external device, data for adjusting wireless power to be output by the device, the data being based on information indicating a degree of proximity between the external device and at least a part of a human body identified using a sensor module of the external device, and
• transmit power adjusted based on the data to the external device through the wireless charging module.

An electronic device comprising:

• a battery;
• a coil;
• a power reception circuit configured to be electrically connected to the coil and the battery;
• a sensor module;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• acquire power received from an external electronic device using the coil,
• check a proximity to an external object using the sensor module while acquiring the power, and
• transmit, to the external device, information for adjusting the power by the external device based at least on the proximity.
