iOS device crash when load model big size

I have a model big size :

  • Verts ~ 10 milions
  • Faces ~10 milions.
    I use blender export model with Draco compression.Model size after export: ~ 40mb.
    I load successfully on web browser PC but crash on ios device!
    I want to ask if there is a size limit for the model when loading on ios device ? Or is there a way to fix the above problem. Models have been reduced poly!

Device limits depends on the respective hardware, OS and browser so there is no defined limit. But according to your data, the geometry complexity is probably too high especially for (older) mobile device.
