Abstract: Various embodiments relating to an electronic device and a method based on a battery leakage state have been described. According to an example embodiment, an electronic device includes a display; a communication circuit; a battery; a current sensor configured to measure a charge current used for charging the battery; and a processor, wherein the processor may be configured to measure a charge current using the current sensor, to determine a leakage state of the battery based on at least a part of the charge current, and to provide a notification corresponding to the leakage state through the display and/or perform a specified function corresponding to the leakage state based on at least a part of the leakage state.
