Apple iPhone 5 16GB (White)

Updated on 31/05/2013 with more sample shots from the camera

There's a very simple way to describe the Apple iPhone 5: thinner, lighter and a bit taller than the iPhone 4S. While that gets across the general look of the phone, it rather underestimates what's gone into the design to achieve this.

SIZE AND WEIGHT

For starters, Apple has managed to shave 1.4mm of the thickness of its previous phone. When you compare them side-by-side, what Apple has done is immediately obvious. While the iPhone 4S' screen and back bulged out from the side, the iPhone 5 has a flush back, while the screen is barely raised at all.

There's no denying that the iPhone 5 is impressively thin

It's easy to tell the difference is size from photos, but weight's an altogether harder thing to describe. In pure stats, the iPhone 4S weighed 140g, while the iPhone 5 is 28g lighter at just 112g. Trust us, this is a big difference and it's immediately noticeable when you pick the iPhone 5 up: you get the feeling that it simply should weigh more, it's that light.

While the iPhone 4S and iPhone 5 are clearly related, there are some cosmetic changes to the new model, which give it a different look and help keep the weight down. Gone is the all-glass rear, replaced instead with an aluminium panel that covers most of back of the phone, bar two glass panels at the top and bottom. We've been told that during manufacturing the rear of the phone is photographed with the aluminium panel in place, so that the best-fitting glass panels can be found. Our review model was certainly well put together, with a flush fitting rear.

SCREEN

One of the biggest reasons for the change in size of the iPhone 5 is because it has a larger 4in screen with a 16:9 aspect ratio, rather than the 3:2 aspect ratio used on the iPhone 4S. What this means in practice is that both screens are the same width, but the iPhone 5's is slightly taller, with a resolution of 1,136x640 (the iPhone 4S had a resolution of 960x640), maintaining the same high 326ppi. That's still a Retina display, which Apple defines as a screen where you can't see the individual pixels.

Extra resolution is useful, as you can now fit five rows of icons on the homescreen, up from four on the iPhone 4S. It also makes sense when you use a lot of the applications: you can view more calendar appointments and emails in a list, for example.
