Abstract:
A method for controlling power in a battery-powered electronic apparatus is disclosed. The electronic apparatus includes a battery, a detection unit and a power consumption estimation unit. The battery supplies electric power to each device within the electronic apparatus. The detection unit periodically detects total power consumption of the electronic apparatus and device information representing an operating state of each device within the electronic apparatus. The power consumption estimation unit estimates power consumption of the each device based on the detected total power consumption and the detected device information of each device.
