1. A power management method for an electronic device operated with a driving current, the power management method comprising:

  • (a) reading the driving current;

    (b) determining if the driving current is less than or equal to a first steady current value for a first period of time, wherein the first steady current value is an initial current set value;

    (c) turning off a first electronic module of the electronic device to decrease the driving current when the driving current is less than or equal to the first steady current value for the first period of time, wherein the first electronic module corresponds to a first current variation parameter;

    (d) determining if the driving current is within a first judging range for a second period of time, wherein a maximum value of the first judging range is a sum of the first steady current value and the first current variation parameter, and a minimum value of the first judging range is a difference between the first steady current value and the first current variation parameter;

    (e) updating the first steady current value with a second steady current value when the driving current is within the first judging range for the second period of time, wherein the second steady current value is a difference between the first steady current value and the first current variation parameter;

    (f) determining if the second steady current value is less than or equal to an energy saving set value; and

    (g) activating an energy saving mode when the second steady current value is less than or equal to the energy saving set value.
