Welcome to iPhone SE, the most powerful 4-inch phone ever. Inside its compact design, iPhone SE is powered by the A9 chip with integrated M9 motion coprocessor. Its 12MP iSight camera captures photos and 4K video with stunning clarity. And of course, there’s Live Photos, which brings your images to life. Add in Touch ID and iOS 9 — the world’s most advanced mobile operating system — and the result is an iPhone that looks small. But lives large.
