Mobile performance

Ok I did that and won some FPS.. still, it goes a bit too low... anything else I can do?

You could try using a larger timestep too, eg 0.03. Then set the max fixed timestep to 0.06 to limit Unity to 2 physics updates per frame.

Assuming you're using the Burst backend, and that the bottleneck is indeed the simulation (FixedUpdate) not much else can be done. Maybe use less density iterations, less substeps, etc. until performance is acceptable without quality suffering too much. Fluid simulation is really expensive, so it won't perform well in lower-end devices in general.
