The 3D Touch is clearly the most innovative feature of the new iPhone 6s and iPhone 6S Plus. It allows you to play with the phone and its apps in new and interesting ways. Taking over from the Force Touch that makes it easy to access the Apple Watch and new iOS interface, 3D Touch makes interacting with the phone even more interesting. You can pull down the menu, create shortcuts and access features of the same phone in new ways. Apple has also worked on some physical features of the phone. To make a sturdy iPhone, Apple has used a custom-made aluminium alloy. The display glass is the Ion-X that has been used to make the Apple Watch, which should make it a little more flexible. The new iPhone 6S is the same size as the previous phone. However, it uses the new A9 64-bit processor and Apple says it will offer 70 percent faster CPU and 90 percent faster GPU. There is also a 12MP rear camera on the phone now, a big leap. There have been many improvements over the older iPhone 6 in the new launch. However, these features have been part of many competitors for a long time now. It would be worth your while to think well before shelling out $199 towards the phone.
