Are you tempted by the latest iPhone? Or would a device from a slightly older generation serve your needs? With iPhone SE, iPhone 6S, iPhone 6S Plus, iPhone 7 and iPhone 7 Plus all currently available, alongside the new generation made up of iPhone 8, iPhone 8 Plus and iPhone X, making a decision between each of Apple's smartphones can be difficult. This is made especially difficult since they all offer cutting-edge tech specs, speedy processors and great cameras.

iPhone Design

Apart from iPhone SE, every other iPhone available shares a very similar look, with sleek rounded edges and a thin frame. iPhone X, however, is Apple's biggest screen to date, with a 5.8-inch Super Retina HD Display that covers the entire front of the handset.

The three newest models, iPhone 8, iPhone 8 Plus and iPhone X, also share the same rounded shape, but they boast a durable, all-glass front and back. They're dust and water resistant too, as is iPhone 7 and iPhone 7 Plus.

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 most iPhones appear quite similar on the outside, (with the exception of the budget-friendly SE, and the all-display X), 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 iPhones 7, 8 and X 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. These handsets arrive 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 - recent generations of iPhone come 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 iPhone SE to the iPhone X, the camera on all current iPhone models stands at 12MP. While each device produces wonderfully clear images, there are a few differences between the multiple models.

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

The cameras featured on iPhone 7, 7 Plus and 8 use 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, 8Plus and X also includes an additional lens with f/2.8 aperture - labelled as Telephoto by Apple - and these three advanced models are Apple's only dual camera devices.

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.

Apple Security - Touch ID & Face ID

iPhones SE to 8 and 8 Plus all feature Touch ID in the home button, allowing you to unclock your handset quickly and easily with biometric fingerprint technology. To mark Apple's 10-year anniversary, however, the advanced iPhone X introduced a ton of new features, including Face ID.

On iPhone X, Face ID replaces Touch ID to unlock your device through facial recognition. A highly-detailed map is created of your face, ensuring only you can get into your phone - in fact, it's so safe you can even use it to verify purchases on Apple Pay. The removal of the home button on iPhone X has opened up a whole new design possibility, freeing up the front of the device to be an all-screen experience.

Wireless Charging

All available iPhones can be charged up via the handet's Lightning Port for fast and efficient battery management. Apple's latest generation of handsets have another trick up their sleeve however.

iPhone 8, 8 Plus and X are all able to charge wirelessly. Simply place your handset on any Qi compatible charging dock, and juice up for the day without the usual tangle of wires.

Siri

And let's not forget everyone's favourite personal assistant Siri, which is available across all iPhones currently available.

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.
