Abstract: An electronic device includes a charging circuitry; a communication circuitry; a display; a processor; and a memory configured to store instructions that, when executed by the processor, cause the processor to: receive information regarding a remaining capacity of a rechargeable battery of a stylus related to the electronic device from the stylus by using the communication circuitry; based on it being identified that the remaining capacity of the battery is less than a reference value, display a first indication for guiding that charging of the battery is required by using the display; and, in response to it being identified that the stylus contacts the display while displaying the first indication, provide power for charging the battery by using the charging circuitry to the stylus, and to change the first indication to a second indication for indicating that the battery is being charged by using the display.
