Unity3D frame rate dropped after importing Blender model

I am making a 3D game with Unity for Android. In the game there is a main character and up to around 10 opponents possibly on the screen at the same time, all using the same model (prefabs for "opponents" differ only in one material for other colors).

The model was designed using MakeHuman and Blender.

On PC (since rendering is a lot faster) there are no problems, but when testing it on an Android device, the rendering time drops the frame rate to around 25-30 FPS when there are 3-4 or more bodies on the screen, creating a really "laggy" feeling (I am expecting a frame rate of about 60 FPS).

Before importing the Blender model I used placeholder spheres and there was no such behavior. Since this is the first time I am using Blender and such 3D models, I am not sure whether my model is within the expected sizes for a mobile game. My current model consists of: 5,956 Verts, 10,456 Faces, 10,819 Tris with a file size of around 6.5 MB (it was generated even larger by MakeHuman at first, but I managed to compress it and optimize it significantly, but still without major effects).

I attempted different solutions, including merging all meshes in the model into one, turning off shadows, using as least materials as possible, etc. All attempts were with no or very limited improvement.

Any ideas are welcome. Cheers!

for a mobile game I would suggest you to remesh the model (even though its not a nice work, but the results are much better than the decimate-modifyer for example) an than bake normalmaps for it from the high-res model.

Sounds like way too much to me.

Also, keep in mind that if you're doing anything such collision calculations, every extra complexity takes exponentially more time
