you need 2 channels for charging and using the battery (positive, and negative),and at least one channel for data transfer.
At this point most hardware does not support sending data over the line used for the battery, I guess since that would mean that without the battery having remnant charge, the controller would be dead, and therefor the battery would not be able to charge; but that's only an estimation.
Most cellphones have 2 leads, and the third is the data channel to the controller.
