In a nutshell: My MOBILE game has low CPU usage, sometimes as low as 15% but the FPS is also around 10-15 FPS and the game laggs...

Here are the stats on PC:

Might it be the est. image memory or too many objects? 90% of the objects are static and have collisions disabled.

It's just very weird and am wondering if anyone got ideas of what this could be before going from ground up step by step re-building it again.

It probably means it's bottlenecked on the GPU rendering, not the CPU.

I was thinking it's the fill rate, but haven't found a way to check the GPU usage in any way on phones. Isn't there a way at all for this Ashley?

That's what the GPUUtilisation expression is for, but not all devices support it because it requires support in the driver.
