The electronic device includes: a communication circuit for transceiving data, a charging circuit for receiving power via an electrical connection, and controlling a communication channel operative through the electrical connection, a memory, and a processor. The processor implements the method, including: receiving, via the charging circuit, and through the electrical connection, connection information of a first external electronic device for communicatively connecting to the first external electronic device, from a second external electronic device into which the electronic device is inserted and receiving power via the charging circuit, transmitting, via the charging circuit, and through the electrical connection, connection information of the electronic device for communicatively connecting to the first external electronic device, to the second external electronic device, and storing the connection information of the first external electronic device in the memory.

Electronic device using communication channel generated by electrical connection between electronic device and external electronic device, and method for operating electronic device

An embodiment of the disclosure provides a first power receiving device including a battery, a power management integrated circuit, an interface for receiving power from a power supply device, and a processor configured to control a charging current using the power management integrated circuit. The processor may be configured to: if charging from the power supply device through the interface is detected, set the charging current, transmit first charging information associated with the first power receiving device to the power supply device, through the interface, receive second charging information associated with a second power receiving device which is paired with the first power receiving device or associated with the power supply device from the power supply device, through the interface, and control the charging current by comparing the first charging information and the second charging information.

Power receiving device and method for controlling a charging current

According to various embodiments, an electronic device comprises a short range communication circuit; and a processor, wherein the processor is configured to: establish a communication channel with a first external electronic device by using a designated communication scheme, through the short range communication circuit; transmit information related to the communication channel to a second external electronic device through the short range communication circuit; receive a request to transfer communication rights with the first external device to the second external device; and transfer communication rights with the first external device from the electronic device to the second external electronic device.

Wireless communication device and method for transferring communication rights between electronic devices

An electronic device and method for operating the same. The electronic device includes a communication interface; a rechargeable; a timer; a first processor operably coupled to the communication interface, battery, and timer; and a second processor operably coupled to the battery, wherein the first processor is configured to receive, from an external electronic device, information associated with time; while remaining capacity of the battery is greater than or equal to a reference value, obtain, by using the timer, first information associated with time that is elapsed since the information is received; and in response to identifying that the remaining capacity is less than the reference value, switch a state of the second processor to an active state, and wherein the second processor is configured to obtain second information associated with time that is elapsed since the second processor is switched to the active state; and in response to detecting that the electronic device is connected to another electronic device for recharging the battery, provide the second information to the first processor.

Electronic apparatus and method for controlling time measurement

An electronic device is provided. The electronic device includes a communication circuit configured to support communications by a first communication scheme and a second communication scheme; and a processor, wherein the processor is configured to establish a first communication channel corresponding to the first communication scheme with a first external electronic device using the communication circuit; receive, from the first external electronic device, configuration information related to the first communication channel; transmit, to the first external electronic device, audio data through the first communication channel such that the first external electronic device outputs the audio data using the first communication channel; and transmit, to the second external electronic device, the configuration information related to the first communication channel through the second communication channel corresponding to the second communication scheme such that the second external electronic device is capable of acquiring the audio data using the configuration information.
