A power management method for use in an electronic system is provided. The electronic system has a processor and a power management unit. The method has the steps of: when the processor has entered a low power state and an awakening event occurs, calculating a staying time from the time point the processor enters the low power state till the time point the awakening event occurs, wherein the operation voltage of the processor is at a first voltage level in the low power state; and when the processing starts to exit the low power state according to the awakening event, determining a wait time, during which the operation voltage of the processor is recovered to a second voltage level of a working state from the first voltage level, wherein the first voltage level is lower than the second voltage level.
