Yes, they look the same as their predecessors on the outside. But the iPhone 6S and iPhone 6S Plus are no slouch upgrades. For starters, there's the new force-sensitive touchscreen that gives you new shortcuts and gestures from both the home screen and inside apps. That 4.7 or 5.5-inch screen is covered by a new, stronger kind of glass, while the metal shell is made from the same custom alloy as the Apple Watch for greater strength. Of course, there's a faster A9 processor, and since the iPhone is the most popular camera in the world, it got a healthy boost, too, with a 12 megapixel sensor, faster autofocus, and 4K video shooting and editing on the back, a new 5 megapixel sensor on the front that uses the screen as a flash, and new Live Photos that use burst shooting to turn still shots into GIF-like shorts.
It's not the only phone to shoot 4K video. It's just the only one that can play it back natively. The screen of the Sony Xperia Z5 Smartphone measures 5.5 inches, yet packs in full 4K Ultra HD resolution, making it the sharpest, highest-resolution display you'll find on a phone. The camera is similarly impressive, with a Sony-made 23 megapixel sensor, Hybrid Autofocus that can lock on to your subject in as little as 0.03 seconds, and a bright f/2.0, 24mm wide-angle lens. Other features include 4K video capture (obviously), an integrated fingerprint sensor for added security, and a battery that lasts for up to two full days.
