What are haptics on iPhone?

"Haptics" on iPhone refer to haptic feedback, which is the vibrations and tactile sensations the device produces to physically respond to user interactions, such as pressing a key on the virtual keyboard or performing an action. You can enable and customize these settings by going to Settings > Sounds & Haptics. Here you can choose to enable or disable vibrations and, depending on your iPhone model and operating system, customize the intensity and conditions under which haptics are activated, such as only in silent mode or always on.

Haptics are essentially a vibration. They can be very useful for notifications if you have the sound turned off.

My pleasure :)
