Abstract
According to one embodiment, an electronic device includes a power supply circuit configured to supply, to a battery, a first charge current for a quick charge and a second charge current for a normal charge smaller than the first charge current, the first charge current and the second charge current being generated from a power from the external power supply, and a controller configured to supply the first charge current to the battery to perform a quick charge when a difference value between a first voltage value of the external power supply wherein the power supply circuit supplies a third charge current smaller than the second charge current to the battery and a second voltage value of the external power supply wherein the power supply circuit does not supply the charge current to the battery is smaller than a threshold.
