If you're rocking a new iPhone 6s, then you've no doubt felt the difference that the new Taptic Engine makes when it comes to vibrations. Vibrations are now audibly quieter on the iPhone 6s, yet still just as strong, if not stronger. If you've ever felt a vibration from the Apple Watch, a device the necessitated the creation of the Taptic Engine, then you already understand the difference.
You'll also notice a new default vibration option for text tones in the Settings app. The new default vibration, called Synchronized, replaces the older Staccato default vibration from older devices. Synchronized allows for the Taptic Engine to sync with the sound of a selected text tone. This provides users with a unique vibration that matches each selected text tone, which is really cool.
We've created a video highlighting some of the differences between iPhone 6s Plus and the iPhone 6 Plus' vibration patterns. It's a change that goes unnoticed to the eye, but you can certainly feel and even hear the differences.
