A method and apparatus are presented in which power drawn from a cellular phone by ancillary devices can be reduced by automatically turning the ancillary devices on or off depending on the detected movement and/or the indoor or outdoor location of the cellular phone. The ancillary devices may be, for example, a satellite signal receiver, an infra red transceiver or a short range radio transceiver. Other possible automatic actions in response to the motion or location type detected may be brightening or dimming a display or increasing or decreasing the volume of an audible alert. |
