The iPhone SE is a smartphone made by Apple Inc. It was released on March 31, 2016. It has almost everything the iPhone 6S has but in the body of an iPhone 5S. It does not have 3D Touch or a barometer. However, just like the iPhone 6S, it has an improved Apple A9 system-on-a-chip, an improved battery, and an improved camera that can record 4K video.
