Abstract: Data indicative of resource usage patterns (RUP's), application usage patterns (AUP's), power consumption and application performance is automatically and repeatedly collected from individualized mobile devices, aggregated into a cloud based database and sorted into categories according to device hardware type, device software type and user type. Optimized power management policies for the sorted classes of device hardware types, device software types and user types are developed in the cloud and downloaded into individualized ones of the mobile devices fitting into the respective classes.

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 comprises: a non-transitory memory comprising an application; a controller coupled to the memory and configured to adjust a configuration associated with the application independently of other applications in the apparatus, wherein the configuration is an assignment of resources of the apparatus; and a profiler coupled to the memory and configured to: measure a measured performance corresponding to the configuration; and measure a measured power consumption corresponding to the configuration. A method comprises: determining a performance associated with an application; executing a configuration associated with the application in order to substantially maintain the performance while reducing an energy consumption associated with the application; measuring a measured performance resulting from the executing; and adjusting the configuration in response to the measured performance.
