Chief among them is a pressure-sensitive screen, enabling a feature that Apple calls 3D Touch. 3D Touch allows you to press down on the iPhone’s screen to pull up new menus, activate shortcuts, and generally interact with the device in new ways.
For example, you could lightly tap on the content of an email to peek at the content inside, and if you press harder, the content you’re peeking at will pop open fully.
As is standard with Force Touch, the iPhone will offer haptic feedback as a part of the 3D Touch experience.
A few examples of 3D Touch on the iPhone include: lightly tap on the camera icon to get camera options, and press harder to go straight into selfie mode, lightly tap on various app to choose to go into various parts of the app, lightly tap on a flight number and get flight tracking information as a ‘peek’, or Force Touch an address to get a preview within the Maps app.
It’s not just default Apple apps that use Force Touch — Instagram, Facebook and others have integrated 3D Touch into their apps to let you peek and pop.
The new A9, found in the iPhone 6S and 6S Plus, is the third generation of the 64-bit chip Apple has been using, built with a new transistor architecture. It’s 70 percent faster than the A8 chip used in the iPhone 6 and iPhone 6 Plus, and 90 percent faster graphics performance than the previous generation.
For the first time in years, Apple is adding more megapixels to the iPhone camera, offering a 12-megapixel camera. That’s a 50 percent improvement from earlier generations of the iSight camera.
But in order to avoid trading off more pixels for lower image quality, Apple has introduced ‘deep trench isolation’, which separates photo diodes to help maintain accurate color quality and reduce crosstalk and noise.
The new iSight camera still protrudes slightly from the body of the phone, just as it does on the iPhone 6 and 6 Plus.
Beyond still imagery, the new iSight camera is also capable of taking 4K video, which means each frame has 8 million pixels.
Some Other Stuff
The new iPhones support 23 LTE bands up to 300mbps, alongside WiFi up to 866mbps. And if you’re thinking of jumping ship from Android to iOS, Apple is releasing a new app that will help you move over your photos, notes, etc. There are also a bunch of new iCloud storage pricing plans, with 50GB for $1/month, 200GB for $2.99/month, and 1TB for $9.99/month.
In terms of pricing and availability, the new iPhone 6S and iPhone 6S Plus will come in the exact same prices and configurations as the previous generation, starting at $199 and $299 respectively for the 16GB model.
