Apple iPhone 6s: Full specs and a review of new features

When the iPhone 6s was first released in late 2015, as with most iPhones, it was at the top of its class. But fast forward a few years later, is the phone still worth purchasing?

Even though Apple has since stopped selling this model, you can still buy it from other stores. And iPhone 6s still has a handful of features going for it, so keep reading, and we’ll see how it holds up against newer phones on the market.

iPhone 6s features in detail

Even though the iPhone 6s looked almost identical to its predecessor, it was released with a handful of new features. Things like its 12-megapixel camera and the ability to use the “Hey Siri” command without the phone being plugged into power were obvious next steps for this iPhone.

But that’s not all there is to iPhone 6s. It introduced features like Live Photos, which turn your pictures into short video clips instead of just a single frame. And it also brought 3D Touch, which created a whole new way for people to interact with their phones by using pressure instead of just tapping.

And the last of the iPhone 6s features — which has only recently become a sought-after commodity — is the headphone jack. Every iPhone that’s been released since the 6s has only come with a lightning port.

iPhone 6s camera specs

As was briefly mentioned earlier, the iPhone 6s came with a 12-megapixel camera. However, it wasn’t until the iPhone 7 that having the dual-rear camera became standard on iPhones. So, the 6s only has a single rear camera and a front-facing camera.

The good news with this camera is that it can record video in 4K quality. To make sure you’re recording in 4k on your iPhone 6s just go to Settings > Camera> Record Video and select the right setting. Just note that the frame rates on iPhone 6s may be lower than on newer iPhone models.

With a new camera, it’s tempting to start taking photos of everything. But if you’re doing that, you probably have tons of pics that look the same. Download an app like Gemini Photos to find those and clean them out.

What’s the size and dimensions of an iPhone 6s?

The iPhone 6s came in the same size as the previous model iPhone 6. But due to some controversy that surrounded the casing of the iPhone 6, Apple addressed it with the 6s and gave it a slightly thicker case. That made it just a tad heavier.

The specific iPhone 6s dimensions are 5.44 x 2.64 x .28 in, and it weighs 5.04 oz.

What kind of screen does the iPhone 6s have?

For the most part, the iPhone 6s screen size didn’t see much of a change from the previous model: the diagonal stayed at 4.7 inches. And the iPhone 6s screen resolution is 750px, true to  Apple’s signature “Retina display” brand.

iPhone 6s RAM and storage

Now, before jumping into how much RAM and storage the iPhone 6s has, I think it’s best to quickly clarify the difference between the two. Because they’re both measured in gigabytes, it’s easy to confuse the two things.

If you think of your iPhone as a car, the storage would be how much trunk space your car has, while the RAM is your engine — how fast you can haul all the stuff in your trunk.

With that being said, the iPhone 6s specs include 2GB of RAM, which is still pretty decent by today’s standards. For comparison’s sake, iPhone Xs comes with 4 GB, so the 6s isn’t too far behind.

When it comes to storage on the iPhone 6s, your options are 16, 32, 64, and 128 GB. Which, again, is not bad by today’s standards. The only thing that might give you storage trouble is recording videos in 4K: 40 minutes of 4K footage can fill up the entirety of the 16GB iPhone.

If you opt for a lower capacity iPhone 6s, like the 16 GB model, you’ll want to be smart about storage. Use Gemini Photos to make sure you’re not wasting space on similar photos, old screenshots, and other clutter.
