Android APK acts different than in Editor

Hello, i have been trying to fix this issue for days and haven't found a solution yet.

I have a Cube in the middle of the screen which i am trying to move left and right when the user swipes over the screen. In the Editor this works perfectly without any problems, but when i build the game on my device (Huawei P8) and run it, the movement of the cube slows down extremely (it takes me like 4 swipes over the screen to move the cube from one side to the other, when it takes only one in the editor). I dont think this has to do with the resolution of the phone, because everithing else looks almost the same (except for the UI). I have tried this on my friends phone and the same problem existed, so it can't be an error by my phone.

Code:

 // Move Cube
                 Touch input = Input.touches[0];
 
 
                 if (input.phase == TouchPhase.Moved)
                 {
                     Vector2 deltaPos = input.deltaPosition;
                     if (transform.position.x + deltaPos.x / 100 <= rightEdge &&
                          transform.position.x + deltaPos.x / 100 >= leftEdge && 
                          touchesGround)
                     {
                         transform.Translate(deltaPos.x / (100 - swipeSpeed), 0, 0);
                     }
                 }
