1. A portable communication device, comprising:
- a transceiver radio;
a display coupled to the transceiver radio;
a sensor for detecting a user condition of the portable communication device, wherein the user condition can comprise a continuous talk condition when the user is assumed to be talking on the portable communication device;
a processor programmed to at least reduce power provided to the display when the sensor detects the continuous talk condition; and
a push-to-talk button that operates the portable communication device in a dispatch mode and that serves as the sensor, wherein the processor detects the continuous talk condition when the push-to-talk button is activated a predetermined number of times.

Abstract
A portable communication product (10) such as a cellular phone includes a transceiver radio having a microphone (20), an earpiece (22), a keypad (18) and a display (12) coupled to the transceiver radio. The portable communication product further includes at least one sensor (24, 26, 28, or 30) and a processor (16). The sensor can be used for detecting a user condition of the portable communication device such as a talk condition when the user is assumed to be talking on the portable communication product. The processor can be programmed to at least reduce power provided to the display when the sensor detects the talk condition.

17. A method of power management for a radio communication device having a display, comprising the steps of:
-
detecting a continuous talk condition through the use of a push-to-talk button that initiates a dispatch call on the radio communication device, wherein the continuous talk condition is detected based on the push-to-talk button being activated a predetermined number of times; and in response to the continuous talk condition being detected, at least reducing the power provided to the display. - View Dependent Claims (18, 19, 20, 21)
