Claim 14:
15. A method for exchanging data between a mobile device and a power source device over a power line between the power source device and the mobile device, the power line comprising a single electronic connection from the power source device to the mobile device, the method comprising:
operating the mobile device and the power source device in a first mode, wherein in the first mode the mobile device and power source device exchange data over the power line the electronic connection from the power source device to the mobile device established by contacts on the power source device in contact with contacts on the mobile device;
detecting, by at least one of the power source device or the mobile device at a first time, one or more conditions;
determining, based on the one or more conditions, not to exchange data over the power line; and
responsive to at least a level of battery charge in the power source device being under a power level threshold value, switching to a second mode, the second mode comprising:
shorting impedance in the power line;
the mobile device and power source device not exchanging data over the power line; and
the power source device supplying power to the mobile device over the power line.
