iPhone 7 Plus (black, 2016)

All iPhone 7 Plus models used a 5.5-inch widescreen multitouch Retina HD display at 1920×1080 (401 ppi). It used a taptic-engine that provided a clickless Home button. The iPhone 7 Plus used three cameras: two rear 12-megapixel cameras (one with a wide-angle and one with a 2x telephoto lens) and a front FaceTime HD camera (7 megapixels and 1080p).

The iPhone 7 Plus was originally available in five color options: silver (white glass front and a silver back), gold (white glass front and a gold back), rose gold (white glass front and a pink-tinted gold back), black (black glass front and a matte black back), and jet black (black glass front and a high-gloss anodized and polished black aluminum back). On March 21, 2017, Apple added a (PRODUCT) RED Special Edition with a white glass front and a red aluminum back.

The iPhone 7 Plus was splash, water, and dust-resistant (but not waterproof). It had a Lightning port, but lacked a headphone jack.

Internally, the iPhone 7 Plus used a 64-bit Apple A10 Fusion processor with four cores; 3 GB of RAM; and 32, 128, or 256 GB of storage. It supported 802.11a/b/g/n/ac Wi-Fi, Bluetooth 4.2, LTE (4G), and NFC for Apple Pay.

This iPhone 7 Plus is black with a black glass front and a matte black back. The model number is A1661, indicating that it functioned on the Verizon/Sprint network in the United States (and on cellular networks in Hong Kong and China).

iPhone 6s (Space Gray, 2015)

The iPhone 6s had a 4.7-inch “3D Touch” Retina HD screen at 1334 × 750 (326 ppi). The iPhone 6s cameras were vastly improved over the iPhone 6 that preceded it: a rear 12-megapixel 4K iSight camera and a front 5-megapixel FaceTime camera in 720p (the iPhone 6 used a, 8-megapixel back camera and 1.2-megapixel front camera).

The iPhone 6s was available in four colors: silver (white glass front, silver back); gold (white glass front, gold back); space gray (black glass front, medium-gray back); and rose gold (white glass front, pink-tinted gold back).

The iPhone 6s did not use a physical Home button, but used its Taptic engine to simulate the click. It also used a Touch ID fingerprint sensor in the Home button.

Inside, the iPhone 6s used the Apple A9 processor with 2 GB of RAM and was available in 16 GB, 32 GB, 64 GB, or 128 GB of flash storage. The iPhone 6s was the last iPhone to include a headphone jack (located on the bottom) and used the Lightning port to connect to computer, dock, or power adapter.

This iPhone 6s example is Space Gray, a shade of dark gray with a black glass front.
