Mobile test on unity remote 5 slow

Hello

I am using the crossplatform input manager.

my build is set to android.

When I test on on my iPhone, use connected USB, the feedback is slow/laggy etc.

I can’t really get a feeling of how smooth the gameplay will be.
The game is big so I don’t want to make an actual build.
Is there a way to get realistic realtime feed back or what do people normally do?
Also is there difference in performance between cross platform input manager or the touch count “regular” touch input method??
