The last significant redesign of the iPhone platform came in 2010 with the iPhone 4. It was an update that literally touched all aspects of the device, from SoC to display to baseband and of course, chassis. Last month’s launch of the iPhone 5 is no different in magnitude. The sixth generation iPhone makes some of the biggest changes to the platform since its introduction in 2007.

Visually the device begins by evolving the design language of the iPhone 4/4S chassis. From the launch of the iPhone 4 it was quite obvious that Apple had picked a design it was quite proud of. Thus it’s not too surprising that, from a distance, the iPhone 5 resembles the previous two iPhone models. We’ll get into material differences shortly, but what make the iPhone 5 design such a radical departure is its larger display.

All previous iPhones have maintained the same 3.5-inch, 3:2 aspect ratio display. With the rest of the world quickly moving to much larger displays, and with 16:9 the clear aspect ratio of choice, when faced with the decision of modernizing the iPhone platform the choice was obvious.

The iPhone 5 embraces a taller, 4-inch, 16:9 1136 x 640 display opting to lengthen the device instead of increasing its area in both dimensions. The result is a device that is distinctly an iPhone, albeit a modern one. The taller display doesn’t do much to make desktop web pages any easier to read as a result of the width staying the same. Those longing for an HTC One X or Galaxy S 3 sized device running iOS are out of luck. Reading emails and typing are both improved though as there’s now more room for lists and the keyboard no longer occupies as much of the display. The taller device can be more awkward to use if you have smaller hands, but the added screen real estate is honestly worth it. Once you get used to the iPhone 5’s display, going back to the older models is tough.

The taller chassis went on a diet as well. The iPhone 5 is now considerably thinner and lighter than its predecessor, which is yet another factor that contributes to it feeling more modern.

Internally the device changes are just as significant, if not more, than those on the outside. The iPhone 5 includes LTE support, which in areas where LTE networks are deployed can be enough reason alone to warrant an upgrade.

The iPhone 5 also includes a brand new SoC from Apple: the A6. For the first time since the introduction of the iPad, Apple has introduced a major branded SoC on an iPhone first. The iPhone 4 used the A4 after it debuted on the iPad, and the 4S picked up the A5 months after the iPad 2 launched with it. The A6 however arrives first on the iPhone 5, and with it comes two of Apple’s first, custom designed CPU cores. We’ve always known Apple as a vertically integrated device and software vendor, but getting into CPU design takes that to a new level.

There’s a lot to talk about when it comes to the new iPhone. Whether it is understanding the architecture of the A6 SoC or investigating the improved low light performance of the iPhone 5’s rear facing camera, we’ve got it here in what is easily our most in-depth iPhone review to date. Let’s get started.

    Multiple display reviews conclude that the iPhone 5 has the best display in a smartphone (And much better than a Samsung Galaxy S 3)

    Your second link doesn't compare it to anything but the iPhone 4. Your first link ONLY compares it to the S3. Neither link supports your statement ("best display in a smartphone"). Reply

    A quote from his second link:

    'To put this in perspective, in the past few years I've reviewed probably 30-40 different displays, from PC monitors to TVs to projectors. Not a single one, out of the box, can put up the Gretag Macbeth dE numbers that the iPhone can, and perhaps one projector (which listed for $20,000) can approach the grayscale and color accuracy out of the box.'

    Those pesky facts are annoying! Reply

    No, it's not. There's many reasons the GS3 is the better choice based on the software and hardware, mainly that the MaxxHD only matches a 5 month old phone in hardware specs and tosses on a bigger battery as the only clear win (but you get stuck with a Motorola phone vs most people's preferred choice Samsung).
    But the killer reason is that the charger is on the left hand side.

    For many of us lefties, that is a deal breaker. As a right handed user, you don't realize this. I want the ports on the top or bottom, and I just ordered a GS3 because of this being a tipping point.

    The original Maxx had the ports on the top! Motorola is clueless.
    Never again.

    Ppi does make a difference. Go see the videos of droid dna(has 440) ppi and you can make out the difference. iPhone 5 doesnt have true 720p but that doesn't matter cause it's quite close to 720p. Anyways iphone5 is behind so many smartphones at present. Nokia lumia 920 is a treat to watch with its 332 ppi pure motion hd+ display and high refresh rate, u can make out the difference. But nexus 4 is the smartphone which gives u the best worth for money at ony 350usd it is freaking awesome Reply

    The Physical Comparison table lists the iPhone 5's resolution at 1136 x 960, instead of 1136 x 640. Threw me off for a second there =P Reply

    Oops, fixing. There's always something in the table that needs fixing it seems :P

    And always favorably on the Apple side.

    Maybe you took a picture of the pixel count with the iPhone's camera...

    I know I love how their own benchmarks show how the battery life is worse in just about everything than the 4s and yet and yet "its better" >.> Reply
