Advice on Texture atlas and batching

Hi,

I'm currently developing a test game where I have a car model. Before I used a texture atlas and a single material, I ran the game and got these values from the internal profiler- drawcalls = 19, batched = 4 ; tris = 2928 batched = 440 and verts = 4318, batched = 498. But after I used a texture atlas and applied a single material to all parts of the car, I got these values from the internal profiler- drawcalls = 20, batched = 0 ; tris = 2928 batched = 0 and verts = 4316, batched = 0.

Though the values are close to similar , is this normal ? I'm worried about the batched falling down to zero ! Or should I do anything else to bring down the values ? FYI, I used an Android device and the texture atlas is a png file with all the textures in it. Any advice is appreciated !
