The new iPhone 6s and 6s Plus sports a new pressure-sensitive screen that provides quick and easy access to app-specific shortcuts from the Home screen, while enabling a pair of new gestures within apps like Peek and Pop.
The group that loves tearing things down, better known as iFixit, took a closer look at the 3D Touch function and how it operates in the new devices. In addition, 3D Touch assembly is part of the whole screen assembly and is located at the rear of the display panel.
Furthermore, iFixit noted that Apple worked very close with Corning, the makers of Gorilla Glass, to develop pliable glass for the new iPhone 6s and 6s Plus glass cover. Moreover, the glass bends very slightly when pressed harder, this allows for an array of 96 pressure sensors to measure microscopic changes in the distance between it and the cover glass.
The team also noted that the rectangular capacitor plates are connected to an Apple-design chip through small traces. The chip keeps the capacitors charged and measures changes in current to and from each. With each gold rectangle on the chip, it holds a single plate of parallel plate capacitor. These pressure sensors are much less densely compacted than the points on the iPhone’s separate capacitive touch sensor.

Something worth mentioning, to obscure 3D Touch sensors from view, the new iPhones use a mylar layer that both hides 3D Touch sensors from plain view and reflects diffused backlight outward (as seen above).
In addition, the 3D Touch assembly seems to be quite easy to remove from the backlight, digitizer glass and the display assembly, prompting iFixit to speculate that the new iPhones might be easier to repair.
Furthermore, iFixit’s iPhone 6s teardown team found a smaller battery at 3.8 V, 6.55 Whr and 1,715 may, which is smaller than the 1,810 man battery in the iPhone 6. They also found out that the iPhone 6s held a 2,750 man battery compared to the iPhone 6 Plus’ 3.82 V and 11.1 Whr of energy, for a total of 2,915 mAh.
Lastly, the team found that the new iPhones are much more tolerant to water damage. This means they are not fully waterproof, but can withstand much more than before.
