Abstract
Methods and systems for power conservation in mobile devices are presented. In one example, a mobile communication device includes a first microphone and a second microphone. The mobile communication monitors an ambient noise level and responsive to the ambient noise level operates the mobile communication device in a normal operation mode or a power conservation mode. In power conservation mode, use of the second microphone is discretionary.
