Haptic feedback is a feature on supported iPhone models that provides a vibration response when you perform certain actions, such as touching and holding an icon on the Home Screen. Haptic feedback is a type of haptic technology, which is any technology that gives you a tactile response when you interact with it.

Apples Haptic Touch technology is similar to the previous 3D Touch technology, but it doesnt rely on pressure. Instead, Haptic Touch kicks in when a user long-presses the screen, offering a small vibration as acknowledgement following the press. Haptic Touch is software-based rather than hardware-based, which means it doesnt require a different type of screen technology.

To adjust the haptic feedback settings on your iPhone, you can go to Settings > Sounds & Haptics. From there, you can set the volume for all sounds, adjust the intensity of the haptic feedback, and toggle haptic feedback on or off. You can also customize your haptic feedback by going to Settings > Accessibility > VoiceOver > Audio > Sounds & Haptics.

In summary, haptics in iPhone refers to the vibration response you feel when you interact with your device, and Haptic Touch is a software-based technology that provides haptic feedback when you long-press the screen. You can adjust the haptic feedback settings on your iPhone to customize the intensity and toggle it on or off.
