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.

I don't think there's a good way to measure storage performance on the iPhone. Also not really sure why it matters.repoman27 - Tuesday, October 16, 2012 - link
I timed how long it took to transfer my music library, and clocked 11.1 MB/s writing to the user area of a 64GB model. So no significant change from previous iPhones, and still pretty typical for a smartphone. I'd be interested to get some gauge of the read speeds.And @A5, storage performance affects boot and application load times as well as sync and backup. With a 64GB model, syncing can take quite a while.

Transferring the music library is a LOUSY choice for speed measurement because (depending on your iTunes settings) you may be transcoding all your music to a lower bit rate to fit more on the iPhone; so you are gated by the transcoding performance, not the flash write speeds. I transcode my music (most in Apple lossless on my iMac) to 192kbps AAC for my iDevices, and on my ancient iMac it is the transcoding that throttles performance.A much better situation to look at is transferring large movies. On my devices
- iPhone 4 writes at about 18MB/s
- iPad3 writes at about 22MB/s
Over the last 6 months Anand occasionally has published flash numbers for Android phones and they're generally around half these Apple numbers.
repoman27 - Wednesday, October 17, 2012 - link
Believe you me, I don't allow iTunes to transcode anything, except to ALAC on occasion. But yes, that number I gave was on the low side, but probably more due to it being thousands of files as opposed to one large sequential write.I just transferred a large video file back and forth directly to and from the user storage area of one of my apps, and came up with numbers that are more in line with yours. 23.84 MB/s avg read and 20.05 avg write.
Most MLC NAND modules capable of 20 MB/s writes should be able to do at least 40 MB/s on sequential reads, which leads me to believe that we're still gated to around 25 MB/s by the NAND interface here, which is kinda bogus.

name99, that is not a "better situation" because the performance figures you quote only apply to large block file transfers. It's no more real-world than the figures repoman quoted, which are not "LOUSY". Both are valid, so ideally a proper test should mix both types of data.Furthermore, the idea that your admittedly ancient iMac being crap at transcoding MP3s somehow invalidates somebody else's testing is ridiculous as well. With any decent system that would only be the case if you were shifting data to a device a *lot* faster than any smartphone NAND.
So, you may need to rethink your "victory" a little more.

I've had my iPhone since 9/22 and there is not a single scuff on it. My guess is that in the rush, some units got through QC, but the phone itself isn't any more prone to scratching in normal use than other phones. Meanwhile, Apple being Apple, they have held up production to improve QC even if it means fewer sales in the short run.rarson - Wednesday, October 17, 2012 - link
You've had it less than a month. There shouldn't be any scuffs on it."Apple being Apple"
Ha! That's a good one!

Trololololol"Mine is fine so everyone else is lying". <- Possibly my favourite bogus argument ever. Apple the generous indeed...
doobydoo - Saturday, October 20, 2012 - link
Because it's so much more compelling than the 'Mine is scratched so everyone elses must be'?lukarak - Wednesday, October 17, 2012 - link
But it doesn't rust. It scratches if it comes in contact with something harder. Just as a car does. Would you buy a car that gets a scratched bumper when you hit a wall? Well, maybe you wouldn't but people do. Regularly.This iPhone is no different than every other iPad, MBP or MBA or the first Al MB. Or any other device constructed from aluminium. They scratch if they are brushed against something. It's just normal.
