    When I press on the home button, what exactly happens? Does the button actually press downward at all, or is the vibration just mimicing that? Where does that vibration come from? It's like magic.

    There is no mechanical button at all and no movement. It is just triggering the vibration. Pretty close to magic.

    Nope, the button does not move but the haptic motor kind of gives the sensation of it being pressed. I love it over the old home button. Nothing to wear out and it works so well. Hate to give that up for face ID.

    When you press down, depression sensors capture microscopic differences in the distance between the glass and the sensor, and signal the Taptic Engine to vibrate, the Taptic Engine vibrates by an electrical charge running between the magnets which oscillates the eletromagnetic field and causes the magnets to move due to repelling and attraction when the magnetic field oscillates. These magnets physically moving causes the vibration through the phone.

    Something like that.

    Also, I believe that Apple created sounds for the Home Button presses, so they also trigger the lower speaker to give off these sounds when you press the button.

    Try it when your phone is switched off. You can feel then that there’s no mechanical movement at all. It feels quite strange to do that. It’s very clever how they got it to feel like a physical button.

    Totally fixed. It's incredible, really. It's essentially impossible to tell unless you turn the phone off and push it! Apple absolutely nailed it when it came to the implementation of the haptic home button.

    Keep pressing the home button while the phone shuts off. After a few seconds, the taptic response will stop and you'll really get a good idea of what's happening. :)

    There are people in jail as we speak because the brain is so easily fooled.

    The fake home button doesn't even feel close to the real one on the 6/6S

    you would be the minority of having a button fetish. im pretty sure the revision is just objectively superior in every way.

    I absolutely love it. While it doesn't feel exactly the same as the older home buttons, it's very close and you get used to it really quick. That said, it isn't as good as the haptic feedback on the MacBook Pro but this is likely due to the size constraints

    It Actually feels strange without using the Haptic button anymore on an older model iPhone. What I like about it, is when you push the haptic home button, it's less travel from when you actually had to use the physical home button to push down. So it's a much faster, more responsive method as well.
