Managing energy usage in mobile devices

A mobile device operable for managing energy usage, the mobile device comprising:

• an energy-using component;
• a processor 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;
• receiving on the mobile device at least one environmental characteristic over a wireless network, wherein the environmental characteristic is determined remotely based upon the location of the mobile device;
• 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 upon detecting a change in location between the at least two environments;
• 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.
