A feature pack coupled to and interfaced with a cellular phone, which is able to relieve the cellular telephone from performing tasks associated with several of battery power draining features of the cell phone thus preserving the power of the battery of the cellular telephone. The feature pack, while interfaced and coupled to the cellular telephone, uses its own circuitry and battery to perform these tasks. The feature has a compartment within which the cellular telephone (or other device with which it is coupled) is disposed. The feature pack has circuitry separate from the coupled device, but is able to use audio and other types of signals from the coupled device to perform such tasks as using speakers, microphones, recording voice and audio signals and communicating with external devices via a Blue Tooth interface. |
