iPhone 6S Plus
The iPhone 6S Plus sports the larger 5.5 inch screen, but shares most of the same features of the iPhone 6S.
Top view
The iPhone 6S Plus looks and feels exactly the same as last year's model.
Bottom edge
Like last year's iPhone 6 Plus, you'll find the headphone jack, Lightning USB charging port, the microphone, and speaker all on the bottom edge of the device.
Home button
The home button is right where you'd expect, but the main difference is under the hood. Both the iPhone 6S and 6S Plus have the second-generation sensor that promises to snap the phone open faster than before.
Side view
Here you can see the volume rocker and mute/vibrate switch, but it's really not much different from last year's models.
3D Touch
What was called Force Touch on the Apple Watch has now been renamed 3D Touch on the iPhone 6S devices. When you press down on the camera icon, you immediately get options to take a selfie, record video, record slo-mo, or just take a photo -- all before opening the app.
3D Touch for Photos
A hard press on the Photos app will help you quickly get to your most recent photos, your favorites, or perform a search.
3D Touch for Messages
Press down on the Messages icon to quickly create a new message or pick from favorite contacts.
