Is rigibody velocity frame rate independent?

I have this problem when I'm testing on the editor the the profiler physics have a frame rate of 1000 which is fast so the rigidbody is fast as well but when I tried it on a mobile device the rigidbody quite slow down. So setting rigidbody velocity via user input is bad? Because I couldn't put it on a FixedUpdate since it must trigger on user input.
