How to Disable System Haptics on iPhone
The new iPhone models offer subtle system haptic feedback when performing various actions in iOS. This physical haptic feedback is performed through the Taptic Engine built into iPhone, and you’ll notice it throughout iOS when activating different features, toggles, buttons, and functions.
You’ll find system haptic feedback when opening Notification Center, Contrl Center, toggling UI switches, opening Spotlight, using onscreen zoom, when scrolling through date and number pickers, refreshing Mail, activating the arrange app icon or delete apps feature, and more.
Some users may not like the system haptics on iPhone however, and may prefer to turn this feature off.
