Abstract: A system, computer readable medium, and method are provided for reducing the power consumption of a mobile device. The method includes the steps of detecting video content to be viewed in an application executed by the mobile device; detecting unwanted content associated with the video content; and operating the mobile device in a low-power mode during playback of the video content in the application in response to detecting the unwanted content. The mobile device may include a memory storing the application and a processor executing the application, which configures the processor to implement the method. Five techniques may be applied in the low-power mode to reduce power consumption including Dynamic Voltage and Frequency Scaling (DVFS), reducing resolution of content, reducing brightness of a display, masking content, and thread throttling. The low-power mode saves energy when playing back videos on the mobile device.

Abstract: An apparatus, method, and computer-readable media are provided for reducing an energy consumption of hardware on which an application is running. In use, a call is received from an application via an application program interface. Such call indicates a state of the application. Further, an action is determined, based on the call. The action is for reducing an energy consumption of hardware on which the application is running. The method continues by executing the action for reducing the energy consumption of the hardware on which the application is running.

Abstract: A location method in a communication network is provided. The method comprises a user equipment (UE) generating a geofence distance between a current UE location and a geofence, the UE comparing the geofence distance to a range threshold R, and the UE using a more accurate location determination when the geofence distance is less than the range threshold R.

Abstract: A mobile device, computer readable medium, and method are provided for web browsing that reduces a power consumption of the mobile device. The method includes the steps of receiving a markup language document that includes a plurality of elements; assigning each element in the plurality of elements a priority value according to a set of rules; and selectively loading rendered content corresponding to the plurality of elements into a window of an application executed by the mobile device based on the priority value assigned to each element in the plurality of elements. The set of rules includes at least two rules configured to assign two or more priority values to at least two subsets of elements in the plurality of elements. Selective loading may refer to loading elements of a web page in a different order compared to a default order of a rendering engine of the web browser.
