In another example embodiment a mobile device is operable for managing energy usage. The mobile device includes an energy-using component. A processor is operable for controlling an operation of the energy-using component by: monitoring at least one environmental characteristic of at least two environments in which the mobile device is operable; tracking a location of the mobile device in relation to the at least two environments; informing the mobile device, based on the tracking, with data relating to the at least one environmental characteristic of the environment in which the mobile device is located; sensing a characteristic of the mobile device; comparing the data, related to the at least one environmental characteristic of the environment in which the mobile device is located, to the sensed characteristic of the mobile device; determining an action related to at least one energy-using operation of the mobile device based on the comparing of the environmental characteristic data to the sensed mobile device characteristic; and controlling the at least one energy-using operation of the mobile device based on the determined action.
