Abstract: In a method for reporting a location of a portable electronic device, an acceleration of the portable electronic device is detected via an accelerometer of the portable electronic device. The portable electronic device is determined as falling when a difference between the acceleration of the portable electronic device and an acceleration of gravity is in a predetermined range. An angular velocity of the portable electronic device is detected via a gyroscope of the portable electronic device when the portable electronic device is determined as falling. The portable electronic device is determined as static when the angular velocity of the portable electronic device equals zero. If the portable electronic device is static for a predetermined time period, location information of the portable electronic device is collected from a global position system receiver of the portable electronic device. The location information is sent to a target electronic device.
