Apple Inc. iPhone & iOS Switching from Android Tweet Share Email Apple has a well-established pattern with the iPhone: the first model of the series number introduces major changes, the second generation adds an "S" to its name and refines the original model with mostly subtle (but still significant) improvements. The company's been following that pattern since the iPhone 3G was replaced by the 3GS, and it hasn't changed course with the 6 series. The iPhone 6S is a lot like the iPhone 6 that preceded it but makes a number of key under-the-hood improvements that should take what's already the best smartphone on the market and make it even better. The iPhone 6S and 6S Plus are virtually identical except for screen size, weight, and battery life. All the key features are available on both phones. Important New Features of the iPhone 6S Key changes introduced on the iPhone 6S include: 3D Touch support: The 6S's screen supports 3D Touch, a feature introduced on the Apple Watch that allows the device to behave differently based on whether the screen is tapped or pressed for a longer period of time Improved cameras: Both cameras on the 6S are substantially improved over the 6. The back camera jumps from 8 megapixels to 12 and can now shoot video at 4K HD resolution. The user-facing camera goes from 1.2 megapixels to 5 and can use the screen of the iPhone as a flash. Also supported are Live Photos, an animated photo that can be activated using 3D TouchBetter internals: The phone is built around Apple's A9 processor and M9 motion coprocessor (the 6 series used the A8 and M8), and sports new chips for speedier connections to cellular and Wi-Fi networks.
