I think you need to be clear on what your actually wanting, as you quoted DanielW on a talk about Instancing which is not the same as batching draw calls. As I said, the calls are batched, you can see this when you view the rendering code, you add mesh batches and send them off to the renderer to be sorted and rendered, to help reduce state switching (which in turn helps CPU processing and GPU processing).
Where as Instancing is a GPU feature to be able to efficiently render the same object numerous times in numerous locations ie. foliage and other terrain meshes. Im pretty sure instancing doesnt work for mobile yet, altho last I heard it was coming (and that was a while ago, so it might already be there).
