Claim:
1. An electronic apparatus including: a controller configured to perform a power management of the electronic apparatus; a battery configured to count cycles of a charging; and a charge circuit configured to perform the charging to the battery by using direct current (DC) power supplied from an alternating current (AC) power supply device, wherein the controller to (i) cause the charge circuit to step down a charge voltage of the battery by (a) a first step-down value for each power cycle during a first time period and (b) a second step-down value for each power cycle during a second time period, the second step-down value being larger than the first step-down value, and (ii) stop the stepping down of the charge voltage of the battery by the charge circuit at least during a third time period that occurs after the second time period.
