1. A method of reducing power consumption of an electronic device, said method comprising:
- determining a first orientation of an electronic device;
receiving an indication of rotation of said electronic device around an axis; and
generating a command to cause an electronic compass module disposed within the electronic device to transition from an idle operating state to an active operating state and to generate a compass heading.

Abstract
A method for reducing power consumption of an electronic device is disclosed. In one embodiment, an indication that an electronic device is oriented in a first orientation is received. An indication of rotation of the electronic device around an axis is received. A command is then generated to cause an electronic compass module disposed within the electronic device to transition from an idle operating state to an active operating state and to generate a compass heading.
