1. An electronic device, comprising:
- a battery;
a power management unit, coupled to the battery,wherein the power management unit reads an output voltage of the battery, and determines whether a variation of the output voltage of the battery within a time interval is greater than a first threshold, andwhen the power management determines that the variation of the output voltage of the battery within the time interval is greater than the first threshold, the power management unit calculates a remaining power capacity of the battery according to the output voltage and the variation of the output voltage within the time interval.

Abstract
An electronic device and a detection method of power capacity are provided. The electronic device includes a battery and a power management unit coupled to the battery. The power management unit reads an output voltage of the battery, and determines whether a variation of the output voltage of the battery within a time interval is greater than a threshold. When the power management unit determines that the variation of the output voltage of the battery within the time interval is greater than the threshold, the power management unit calculates a remaining power capacity of the battery according to the output voltage and the variation of the output voltage within the time interval.
