1. A method comprising: determining, for a software application included in a plurality of software applications executing on a device, an operational priority value associated with the software application, the operational priority value manually configured by a user of the device through a user interface presented on the device and allowing the software application to be ranked relative to one or more other software applications included in the plurality of software applications, the one or more other software applications each associated with respective other operational priority values; detecting at least one of an increase and a decrease in a level of use of the software application by the user; automatically modifying, in response to the detecting of the at least one of the increase and the decrease in the level of use of the software application by the user and based on a resource requirement of the software application operating at the level of use, the operational priority value associated with the software application; retrieving a current battery level and a battery threshold of the device; comparing the retrieved battery level to the battery threshold; and when the current battery level of the device is less than the battery threshold, retrieving a set of color pixel values representative of a software user interface associated with the software application, determining if one or more color pixel values in the set of color pixel values are substantially identical to one or more grayscale pixel values in a set of grayscale pixel values corresponding to the set of color pixel values, and only when the one or more color pixel values are not substantially identical to the one or more grayscale pixel values, making an operational change to the device related to the software application rather than to the one or more other software applications based on the operational priority value of the software application, the operational change comprising converting the one or more color pixel values to the one or more grayscale pixel values to reduce a rate of battery consumption of the device.
