The uvc device should have been put in auto-suspend state if no application is using the device. You can check if there is application which is using the device by 'lsof | grep "/dev/video"'. Also looks power usage estimation of 'power top' should be used when battery provides power, and the data isn't correct if power is provided from power adapter, if I remember correctly.
