If you’re struggling to tell your ‘S’ from your ‘Plus’, our handy guide will help you work out which phone you’ve got.

A lot of confusion exists between iPhone models, especially those with the same overall shape and size – for example the iPhone 5 and the iPhone 5S.

However there are subtle changes made between each and every iPhone release, which means with a little look at the details, you can find out exactly which iPhone model you have.

iPhone 6 and 6+ 

The iPhone 6 and 6+ are Apple’s 2014 phones, and are a dramatic redesign from the familiar angular and industrial models of previous generations. The iPhone 6 and 6+ feature curved sides and curved glass at the edges of the screen. It is also the first iPhone to have the power button on the right hand side of the phone (previously they’ve always been on top). The other distinguishing feature is the camera lens, which sits slightly proud on the rear of the phone.

The difference between the iPhone 6 and iPhone 6 Plus is simply screen size, so you may need to get your ruler out if you’re not sure which you have. The iPhone 6 measures 4.7 inches (12cm) diagonally across the screen, and 15cm from one corner to the opposite corner. The iPhone 6 Plus sports a larger 5.5 inch (14cm) screen, and is 17cm from corner to corner.

iPhone 5C and 5S

The iPhone 5C and 5S were released in 2013. The iPhone 5S featured an aluminium body, very similar to the previous year’s iPhone 5, however the iPhone 5C had a distinctive (and often colourful) polycarbonate plastic casing.

Two distinguishing features of the iPhone 5S are the colours of the body, and the shape of the rear camera flash. The iPhone 5S was launched in three new colour options – Space Grey, White and Gold. Each of these finishes had a two-tone rear panel, with a lighter central matt section and a darker brushed at the top and bottom. Another unique identifier on the iP

hone 5S is flash on the camera. The flash aperture is an oval shape, compared to the round flash aperture on the iPhone 5.

The iPhone 5 was released in 2012, and was the first iPhone to feature a larger 4 inch (10cm) screen. This was large enough to allow a 5th row of icons to be displayed on the home screen, compared to 4 on all previous models.

The main difference between the iPhone 5 and the later iPhone 5S is the camera flash aperture. The iPhone 5 has a round opening for the flash, which was changed to oval on later models.

iPhone 4 and 4S iphone model

The iPhone 4S was released in 2011, and featured a very similar body to the iPhone 4. The easiest way to spot a difference between these two models is to look at the side of the phone, just above the mute switch. If you can see a thin line from front to back of the phone (as illustrated in the image), then it’s an iPhone 4S. If there is no line across the side, it’s an iPhone 4.

Happily, and helpfully, Apple have printed model numbers on the back of every one of their phones, so if you’re still having difficulty identifying your phone there is another way to work out what you have.

Where to look:

The model number is written on the back of the iPhone, in the lines of text under “iPhone”. These all start with “A”, followed by four digits.
