After using the iPhone SE for a couple weeks, I have now switched back to a slightly larger smartphone, for a lot of the reasons I outlined here. But that doesn't mean the iPhone SE isn't a good phone, or that I wasn't impressed by it; it's actually a pretty powerful smartphone, and it's easy to see why a lot of people might consider it. But if you're still deciding between a four-inch iPhone SE and a 4.7-inch iPhone 6S, what are the real differences you need to know about? "We" break it down in a video for you.
