Abstract
A method of controlling an electronic device is provided which includes electrically connecting a battery with an external power source using a first switch such that a first portion of a first current supplied from the external power source is supplied to a system circuit of the electronic device and a second portion of the first current is supplied to the battery, determining whether a specified condition is satisfied, electrically disconnecting the battery from the external power source using the first switch and electrically connecting the battery with a resistor using a second switch, if the specified condition is satisfied, verifying an electrical characteristic of a current applied to the resistor while the battery is electrically disconnected from the external power source and is electrically connected with the resistor, and determining whether an operation of the battery is abnormal, based at least on a part of the electrical characteristic.
