Move object by touch 2d

Scripting

Hello. I trying to move the object by touch. It works but the movement is not smooth. How to fix it?

if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved)
{
    Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
                   
    transform.Translate(0, touchDeltaPosition.y * speedTouch * Time.deltaTime, 0);

}

You should move transform.Translate function form If to Update.
If that does not help it may be better to use Lerp function?!
