An electronic device includes one or more low-power context sensors, one or more high-power context sensors, and one or more processors operable with the one or more low-power context sensors and the one or more high-power context sensors. The one or more processors, working with context engines associated with the sensors, minimize usage of the high-power context sensors when determining a context of the electronic device, where that determined context has a confidence score above a predefined confidence level threshold.
