New, stronger "aerospace-grade aluminum" chassis

The iPhone 6S has a new aerospace-grade aluminum chassis that will hopefully avoid the "Bendgate" issue from last year. It also has a chemically strengthened glass display to-boot.

Improved fingerprint scanning

Like the model before, there's a fingerprint scanner built into its home button.

Apple says, "The improved Touch ID sensor detects your fingerprint even faster than the previous generation."

How much faster, you ask? We don't know and Apple is mum on the details.

Smaller battery, same battery life

Apple has equipped the iPhone 6S with a 1,715mAh battery -- a lower capacity than the 1,810mAh version found on last year's iPhone 6. (The "mAh" acronym stands for milliampere-hour, which is a measurement of a battery's power capacity; the higher the number, the better.)

However, Apple says the battery life for the iPhone 6S is identical to the iPhone 6's.

Speaking of Siri

Apple's voice assistant will always be on and you can summon it with a simple phrase. When you say "Hey Siri", the feature will pop-up, just like it does when you hold down the home button.

3D Touch for more options

A new feature is 3D Touch, which works in conjunction with the pressure-sensitive display. Depending on how hard you press on the glass, you can interact with apps in different ways.
