The second generation is always better. With last year's iPhone X, Apple introduced the most significant redesign to the iPhone since the iPhone 4. All three of the phones Apple announced this fall—the iPhone XS, iPhone XS Max, and iPhone XR—are modeled after that blueprint.

That means near-edge-to-edge displays. It also means they have the TrueDepth sensor array, which powers Face ID, the facial recognition feature that replaces the Touch ID fingerprint authentication method used on iPhones since the iPhone 5S in 2013. There's no home button either, which had been part of the iPhone since the very first one back in 2007.
