iPhone 7 home button, is it variable pressure?

its normal. mine does it too

 

I didn't even notice the differences from a soft touch to a firm press. But I can feel the difference in the haptic feedback.

 

I don't think the vibration gets stronger the harder you press. I think it has more to do that you are gripping it harder to apply the pressure so you feel the vibration more.

 

Mine seems to be the same no matter how hard you press the button.

 

I don't think there's any difference based on the amount of pressure. I think it's only perceived difference based on strength of grip.

 

After pressing my button a million times I agree with you. Can't really feel the difference in vibration. But I can definitely hear two different clicks when clicking slow and soft compared to fast and hard.

Edit: Best guess it's there to simulate the behavior of a real button. Neat touch.

 

So this is all with system haptics enabled ?

 

What you are hearing is the sound being output by the speaker to simulate a real click.

Cover up the speaker and you won't hear anything.

 

It feels different based on the pressure you applied but it isn't different. The amount of force you use will affect how it appears to feel.

 

Of course, it's still two different sounds depending on how hard you pressed.

 

you must have some super human ears because i don't hear a difference.

 

hehe. It's louder when pressing fast. And yes I do have good hearing.
