1. A portable electronic device sized and shaped to be received within a holster in a plurality of orientations, the portable electronic device comprising:
- a communication module adapted to provide data communications and voice communications over a wireless network;
an electronic compass including a single magnetometer, the single magnetometer adapted to measure a magnetic pattern of a single magnetic element in the holster along three axes when the portable electronic device is received within the holster; and
a processor adapted to;
compare the measured pattern with at least one known magnetic pattern associated with the single magnetic element for at least one of the plurality of orientations to determine whether the portable device is received within the holster, and if so, whether the portable electronic device is in a first orientation or a second orientation of the plurality of orientations;
if the device is in the holster, then initiate a low power mode; and
if the device is out of the holster then initiate a normal power mode.

Abstract
According to one aspect, a portable electronic device sized and shaped to be received within a holster having a magnetic element. The portable electronic device includes an electronic compass adapted to measure a magnetic field of the magnetic element in at least two axes. When the measured pattern corresponds to a first pattern, the portable electronic device is adapted to determine that the portable electronic device is in the holster.

13. A method of detecting whether a portable electronic device is in a holster, the method comprising:
-
providing a communication module adapted to provide data communications and voice communications over a wireless network; providing an electronic compass on the portable electronic device, the electronic compass including a single magnetometer; providing a single magnetic element on the holster; using the magnetometer, measuring a magnetic pattern of the single magnetic element along at least two axes; comparing the measured pattern to a first known pattern, and if the measured pattern matches the first known pattern, then determining that the device is in the holster. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
