  • Patent number: 8457693
    Abstract: A mobile device is configured to control power consumption. The mobile device includes a detector configured to detect at least one of an active input or a passive condition. The passive condition is determined to be present based on a comparison of a device state or a change in the device state to a threshold. A controller is configured to respond to the detected active input or passive condition by causing less than all components in the mobile device, including the display screen of the mobile device, to enter a power saving mode from within in a calling mode, where an amount of power supplied to the display screen is reduced in the power saving mode. Operational modes of the mobile device include the power saving mode and the calling mode. The mobile device consumes more power in the calling mode than in the power saving mode.
