1. A mobile station, comprising:
- a display;
a proximity sensor adapted to generate a signal indicative of proximity of an external object; and
a microprocessor adapted to;
(a) determine whether a telephone call is active;
(b) receive the signal from the proximity sensor; and
(c) reduce power to the display if (i) the microprocessor determines that a telephone call is active and (ii) the signal indicates the proximity of the external object.

Abstract
In one embodiment, a mobile station including a chassis having a display, a power reducer, a proximity sensor, and a microprocessor. The power reducer controls power consumption of the display. The proximity sensor is coupled to the chassis and causes the power consumption to be reduced when the display is within a predetermined range of an external object. The microprocessor is coupled to the proximity sensor and to the display and automatically activates the proximity sensor based on the mobile station receiving an incoming wireless telephone call.
