1. An electronic device comprising:
a battery; and
a power management module operatively connected with the battery, and comprising a charging circuit which controls charge of the battery,
wherein the power management module is configured to:
monitor a charge state of the battery,
if the charge state of the battery reaches a first designated state, identify a time taken to change from the first designated state to a second designated state, and
determine whether the battery is abnormal, based at least in part on the identified time,
wherein the identified time includes a time taken to an additional charge, a time taken to a random discharge and a time taken to a supplementary charge,
wherein the time taken to the additional charge indicates a time taken to change from a first state having a first voltage that causes the electronic device to display, on a user interface, that the battery is fully charged, to a second state in which the charge of the battery is finished,
wherein the time taken to the random discharge indicates a time taken to change from the second state to a third state having a second voltage for starting a supplementary charge of the battery, and
wherein the time taken to the supplementary charge indicates a time taken to change from the third state to the first state.
