3D Touch is Apple’s iPhone-specific name for the Force Touch feature it introduced with the Apple Watch. It allows the phone to understand the difference between a tap on the screen, pressing the screen for a short time, and pressing the screen for a long time. The phone can then to react differently to each. For example:
You can get a preview of emails or text messages without opening apps by using a short press. A long press on an app reveals a menu of shortcuts for common functions of the app to increase efficiency.
You also need the 3D Touch screen to use Live Photos, which transforms still photos into short animations. If you want to take advantage of 3D Touch, you’ll need to get the iPhone 6S and 6S Plus; the iPhone 6 and 6 Plus don’t have it.
The iPhone 6S has a 12-megapixel camera on the back that can record video at 4K HD resolution. The camera on the iPhone 6 is 8 megapixels and records up to 1080p HD.The user-facing camera on the 6S is 5 megapixels and can use the screen as a flash for taking selfies in low light. The same camera on the iPhone 6 is 1.2 megapixels and has no flash.
If you only take photos from time to time, those differences may not matter much. But if you’re a serious iPhone photographer or shoot a lot of video with your phone, you’ll appreciate what the 6S has to offer. The iPhone 6S series packs more punch than the iPhone 6 in three areas:
Speed: It’s built around Apple’s A9 processor, which Apple says is 70% faster overall, and 90% faster in graphics tasks, than the A8 processor in the 6 series.Motion Tracking: The 6S series uses the M9 motion co-processor, which is the next generation of the M8 in the 6 series. It provides more detailed and accurate tracking of movement and activity.Data Connections: Lastly, the cellular radio chips in the 6S allow faster data connections to phone company networks and the Wi-Fi chips do the same for those networks. You won’t be able to take advantage of that speed until phone companies upgrade their networks, but when you do, your 6S will be ready. An iPhone 6 can’t say the same.
This is purely a matter of style, of course, but the 6S gives you the opportunity for your iPhone to stand out in a crowd or to accessorize with your jewelry and outfits.
