So just to be clear; if you run PDANet to tether, it won't charge (drains slowly). If you don't use PDANet, it will charge properly.

If that's true, it would mean that the juice required by the processing of the data, and/or the constant cell data communication is draining the battery, which makes sense. So you're back to trying to find a way to get more juice to the Diamond, which means either a docking station/AC adapter or dual USB plugs.
