Abstract: A portable electronic apparatus and a battery power management method thereof are provided. The method includes the following steps. A discharge current of a battery is detected. Whether the discharge current is greater than a current threshold within a predetermined period is determined. If the discharge current is not greater than the current threshold within the predetermined period, whether a fully charge capacity of the battery is less than a battery capacity threshold is determined. If the fully charge capacity of the battery is not less than the battery capacity threshold, a relative state of charge of the battery is controlled to be maintained within a first power range. If the fully charge capacity of the battery is less than the battery capacity threshold, the relative state of charge of the battery is controlled to be maintained within a second power range.
