An electronic device includes a charging integrated circuit (IC) including a direct charging circuit that charges a battery; and an application processor that issues a request to an external power source to output a maximum voltage corresponding to a target current, performs a ramp-up operation on a charging current input to the charging IC on the basis of the maximum voltage, compensates for a difference between the charging current and the target current in response to the charging current entering a constant current period, and enters a sleep mode during the constant current period in response to that the charging current reaching the target current.

Electronic device for charging battery based on direct charging and operating method of the electronic device

An electronic device according to various embodiments of the disclosure includes a connection terminal including a terminal; a controller configured to identify a resistance value of the terminal; a capacitance checker configured to identify capacitance of the terminal; and a processor configured to determine whether or not water is present in the at least one terminal based on information related to the resistance value received from the controller and the capacitance received from the capacitance checker.
