Are you tempted by the latest iPhone? Or would a device from a slightly older generation serve your needs? With the iPhone SE, iPhone 6S, iPhone 6S Plus, iPhone 7 and iPhone 7 Plus all currently available, making a decision between each of Apple's smartphones can be difficult - especially since they all offer cutting-edge tech specs, speedy processors and great cameras.

iPhone Design

The iPhone 6S, 6S Plus, 7 and 7 Plus all share a very similar look, with sleek rounded edges and a thin frame. Dimensions-wise, the newer iPhone 7 and 7 Plus have the same measurements as their predecessors, they just weigh slightly less. Yet while all four iPhones look the same at first glance, the iPhone 7 and 7 Plus have been engineered to be dust and water resistant.

The iPhone SE has kept the traditional look of older models, with small differences such as matte edges and an added rose gold option. At just 4 inches, it's the ideal compact smartphone for anyone wanting to enjoy Apple's technology at a fraction of the price.

iPhone specs compared

As the latest iPhones arguably look quite similar, (with the exception of the budget-friendly SE), so it's useful to take a closer look at the internal specs.

In addition to the specs listed above, different generations of iPhone arrive with different features on board.

iPhone Audio

A major design difference between the iPhone 7 series and older models is the new audio set-up. The 3.5mm earphone jack has been replaced with Lighting Port audio connection for improved digital sound. The handset comes with a pair of Lighting Port Earpods in the box, but if you're particularly fond of your old headphones, there's no need to worry - all iPhone 7s comes with a 3.5mm-to-lightning adaptor so you can continue to use your favourite pair if you like.
Also now available are Apple's new Airpods (sold seperately), which offer tangle-free audio, minus the wires. Combining crystal-clear playback with a new sense of freedom, they're ready to help you through long journeys thanks to a charge that lasts five hours. With extra built-in functionality, they can sense when they're in your ears, and will even pause when you take them out. They're also activated with Siri, meaning you can cue up songs, adjust the volume, or make hands-free calls, all with a simple voice command.

Apple 3D Touch

3D Touch was first seen on the 6S and 6S Plus, revolutionising the way you can interact with your iPhone. With 3D Touch, the touchscreen can recognise how much force is being placed on the screen, and react accordingly. This technology brings a whole new collection of useful gestures to the iPhone, include tap, swipe and pinch, peek and pop and quick actions. It's designed to cut down time spent navigating through iOS, and it certainly comes in useful.

For example, while inside the Apple Mail app if you lightly press an email you will see a snapshot of what the email contains. Let go, and you'll return back to the list of emails. Similarly, if you press and hold down Maps a menu will pop up, offering choices such as 'Directions Home' and 'Mark My Location'.

iPhone Camera features

From the SE to the 7 Plus, the camera on all current iPhone models stands at 12MP. While each device produces wonderfully clear images, there are a few differences between the five models.

If taking professional-looking photographs on your smartphone is important to you, consider the finer features of each iPhone. The 6S Plus, 7 and 7 Plus, for example, all include Optical Image Stabilization - a feature which helps to reduce noise and create clearer, defined images.

The camera on both the 7 and 7 Plus is more advanced than its predecessors, as it uses a six-element lens and a f/1.8 aperture with wide colour capture, meaning users can fit more into one photo. The camera included with the 7 Plus also has an additional lens with f/2.8 aperture - labelled as Telephoto by Apple - and is Apple's first dual camera device

All devices can enjoy one of Apple's coolest iPhone features - Live Photos. When taking a Live Photo, your iPhone will record 1.5 seconds of footage before and after you capture an image, including audio. This means you can tap a still image to relive a moving memory of the moment it was taken. Another fun feature, Slo-Mo allows iPhone lovers to capture a video at 240fps in 720p. Just open up the camera, swipe right and enter Slo-Mo mode. From here, you can even adjust which section of the video is in slow motion after you've taken it.

iPhone contract or iPhone SIM free?

Depending on your budget and your preferred payment method, there's a choice as to how to get your hands on your brand new iPhone. You can puchase an iPhone contract to spead the costs over a monthly tariff, or purchase your iPhone Sim-Free to use with an existing SIM or SIM-only connection.
