1. A power conservation method for a global position system (GPS) in an electronic device, the method comprising:
- setting a time interval to acquire movement parameters of the electronic device, the movement parameters comprising an acceleration and a moving direction of the electronic device;
activating the GPS and an accelerometer in the electronic device;
acquiring the movement parameters of the electronic device using the accelerometer at each time interval;
determining if the electronic device is at rest according to the time interval and the movement parameters; and
maintaining an active state of the GPS if the electronic device is not at rest;
ordisabling the GPS if the electronic device is at rest.
