It looks like an iPhone 5s and feels like an iPhone 5s, but Apple’s iPhone SE is not the same device that was introduced in 2013. In one of Apple’s more aggressive plays for the mid-range market, Apple has dressed down its iPhone 6s into a design that many people regard as the pinnacle of Apple’s powers. But in a big phone world, is there room for a 4-inch powerhouse?

While the two devices look virtually identical, Apple has filled its newest handset with guts powerful enough to make the iPhone 6s blush. The iPhone SE comes equipped with an A9 chip, 4-inch display, M9 motion coprocessor, 12-megapixel camera, Live Photos support, a fingerprint sensor, 16GB and 64GB of internal storage, hands-free Siri, and a 1642mAh battery. Who said good things don’t come in small packages?

There’s no arguing the iPhone SE is powerful enough to hang with some of today’s best; it’ll be a matter of whether you are comfortable using a phone of this size. Apple said over 30 million people purchased a 4-inch iPhone last year, so clearly there are people who prefer the smaller form factor. However, with rumors of Apple possibly increasing its larger 5.7-inch model up to 5.8 inches next year, how long can small phone continue to last?

We’ll address these questions in the coming days. We pretty much know what to expect from Apple’s iPhone SE: a smaller iPhone 6s. But that doesn’t paint the whole picture. There are a few differences you need to be aware of other than the size. For one, the iPhone SE’s front-facing camera is a measly 1.2-megapixels, while the device is using the first-generation Touch ID sensor.

With a starting price of $399, will Apple’s newest device rule the mid-range market? Check out the unboxing above to see the device in action.
