One of the major features of iPhones that started with 6s and 6s Plus back then was the introduction of 3D Touch that allows users to perform common tasks. Apple uses capacitive sensors in the display to sense the degrees of touch pressure and lets users use features like “Peek” and “Pop” to preview contents without actually opening an app. The technology offers a plethora of smart features but proved to be unpopular to most users due to inconsistency. Not all apps support 3D Touch.
As expected and rumored before, Apple has confirmed it is killing off the feature as none of the new iPhone has it in their specs page. iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max now has Haptic Touch instead.
Haptic Touch was introduced back in 2018 with the iPhone XR and provides similar features with 3D Touch. The difference is the former only supports long press.
