An example electronic device includes a temperature sensor, a battery, a communication circuit, a connecting terminal, a processor, and a memory. The memory stores instructions which, when executed, cause the processor to control the electronic device to determine whether the connecting terminal is electrically connected with the external electronic device, measure a first temperature around the electronic device, receive first battery state information from the external electronic device, based on the measured first temperature being greater than a specified temperature, determine a first charging state of the battery of the external electronic device, and transmit a first signal for controlling the charging state of the battery of the external electronic device to be less than a first specified level, based on determining that the first charging state of the battery of the external electronic device is greater than or equal to the first specified level.
