The Device Power API allows developers to create a better user experience by giving the user more information about what the system is doing, and more control over the devices in the system. Device Power is useful in situations where power consumption is critical, such as in portable devices running on batteries. For example, the power management scheme used in a desktop computer may not be the optimal scheme for a laptop computer, so the user may want to disable certain devices from waking the system. This can conserve energy because the disabled devices will not draw power while the system is in sleep mode.
