Abstract
An electronic device includes a connector connected to a cable external to the electronic device and including a plurality of pins; a first water detection circuit connected to at least one first pin of the plurality of pins and generating a first detection result by detecting whether there is water in the connector based on resistance of the at least one first pin; and a second water detection circuit connected to at least one second pin of the plurality of pins, entering a water detection mode when the first detection result indicates the presence of water, and detecting whether there is water in the connector based on resistance of the at least one second pin.
