Object rotation speed different on mobile

Hello! As you can understand from the title, i have some rotating objects in my scene that on mobile rotate slower than on unity game panel. This is not a performance issue since i have other objects that rotate at the same speed both on unity and on mobile. What can cause this?

Are you multiplying your rotation value by Time.deltaTime? That should take care of any framerate difference between devices, and also adjusts itself depending where you use it (Update or FixedUpdate).
