We just spent a good amount of time with the iPhone 5. The phone feels very thin and light (obviously), and the improvement in performance is very noticeable compared to the 4S. Apple didn't have any games (and obviously no benchmarks) preloaded on the iPhone 5 demo units so we'll have to wait until launch to really quantify performance.

The display does look noticeably better than the 4S and the extension of the screen height seems natural. We'll be posting more detailed impressions later on, but for now enjoy the photos/video below:

Update: So we've spent even longer with the iPhone 5 and have some pretty solid impressions of the device. First, the display is indeed noticeably more vibrant than the 4S, which isn't super surprising considering Apple's move from on-cell to in-cell touch and full sRGB coverage. We'll be able to tell in due time just how close it comes to 100% sRGB, but what we saw was very impressive. Touch response remains completely fluid and 1:1, if you're concerned about going to in-cell introducing digitizer recognition issues, rest assured there didn't seem to be any here.

The iPhone 5 also feels substantially different in the hand. It always shocks me how much a simple materials change makes something feel, and it's always impossible to convey these differences, but the lighter and thinner form factor is very perceptible. The 4 and 4S always felt solid, the 5 moves to a much more ethereal form, and the lightness almost makes it feel like a hollow metal box. It's very hard to convey. Likewise the cutouts at top and bottom appear to be glass, but there's no noticeable gap between them and the unibody metal main body; this is very polished.

One of the questions I had upon seeing the change to 16:9 aspect ratio was what the landscape keyboard UI would look like with this larger real estate. The answer is that it simply extends all the way across and takes full advantage of it. 

Apple didn't call out the nanoSIM explicitly, but side by side with the 4S it is immediately obvious this is indeed true, as the removable slot indeed is smaller. You can see that above.

The 4 and 4S construction consisted of two glass plates which snapped onto the metal antenna band that circled the phone. With the 5 this changes fundamentally - the back no longer has a piece which attaches, and likewise there's no corresponding gap on the top for the display. The 5 instead has a polished edge chamfer which runs around the external band. In addition the 5 also continues to use the dual cellular antenna architecture first introduced with the iPhone 4 CDMA for Verizon, then made official on the 4S. These are the bands whose position remains roughly the same on the 5. 

Performance is noticeably improved on the 5 as expected given the presence of two Cortex A15 CPUs inside the new Apple A6 SoC. Of course, Apple allowed no benchmarking at the event so we couldn't run any objective tests, but we pulled up Maps and 3D buildings which didn't appear to drop any frames. Compared side by side with the 4S showing 3D buildings in downtown San Francisco it was even more dramatic. Safari loaded pages quickly over the event WiFi and on LTE, but we couldn't explicitly time anything. 

Inside Settings Apple has included an LTE toggle just like on the iPad 3 with 4G LTE. I didn't get a chance to see if FieldTest.app was present, unfortunately. 

Camera on the 5 launched and performed very well. I was able to rapidly snap photos on the device, though it's always hard to tell whether this is any faster than the previous generation without using a timer or capturing video. As a reminder, the iPhone 5 camera is still 8MP with likely the same CMOS sensor as the 4S, but slightly different optics. This time around the iPhone 5 rear camera is still F/2.4 but has a slightly wider field of view. Focal length appears to be slightly changed. Panorama works very well on the 5, it appears to be continually integrating while moving rather than taking a small number of individual captures. Apple has also changed the camera UI just for the iPhone 5 it appears, with a circular capture button and edge to edge bleeds for the preview. This looks a lot like the iPad camera interface. I played with the new 720p front facing camera as well, and quality looked good.  

Note, this number is just an ASOS station I use for testing

Before heading off to play with the new iPods, I also placed a call to Anand and got some worried plus puzzled looks from onlookers. I think it's safe to say that we're living in the future when using a phone like a phone draws ire. In that brief time though I was able to roughly gauge voice call quality, which seemed very good. Interestingly enough I could tell that the earpiece noise suppression was working, as I felt the same kind of light pressure I do with active noise cancelation headsets. 

I switched one of the demo units from WiFi (which was no doubt on 5 GHz, as it was working properly in an environment with crowded 2.4 GHz spectrum) to LTE and though I wasn't allowed to run a speed test, pages loaded quickly and there appeared to be no issues. There are three different models with different air interface and band support, as unfortunately even with MDM9615 there's no way for Apple to deliver truly world-mode LTE compatibility with all of the bands on one device. The PCB shots I saw this morning also seemed to suggest RTR8600 instead of WTR1605 like I originally suspected for transceiver, though the baseband is indeed MDM9615. Of course, you still need the corresponding power amplifiers even with a transceiver that supports more ports. 

Overall after our short time with the iPhone 5 I'm very positive about the end result. The combination of new silicon and LTE alongside display and camera improvements craft a very positive outlook for Apple's iPhone line.

    Really? Seriosly?
    I have those you mentioned... seriosly? SERIOSULY?

    I have an HTC One S, Galaxy S III, and iPhone 4S. (as well as older iPhones and Android phones, and WP7s)

    I use the One S with CM10 (custom ROM with mostly stock Android 4.1 UI) because I like the superior Google integration. But the iPhone is the most usable, stable, consistent, and has the best battery life. No contest.

    Why do you think most reviewers who get to play with all of the different phones use iPhones?

    I always recommend the newest iPhone to my less tech saavy friends. People who like and buy Apple products aren't brainwashed, they're just people who've actually used Apple products without preconceived biases.

    "Its not wider so that you can still operate the phone with only your thumbs. Thats the entire point of the form factor."

    Even in landscape it's easy to operate a large smartphone with thumbs only.

    The main reason Apple didn't increase the size is because it would offer lower pixel density, and they spend the last years arguing that the higher the pixel density, the better. They also want the device to remain small and pocketable. They are pretty much alone in the high end + small display smartphone market so I think it's not a bad strategy.

    they could have made 1280x720 resolution on a 4.5 inch screen which is exactly 326 ppi, so I don't think that's the issue here. But I think screen of Iphone 5 is perfect for large crowd in general and i use tablets to watch movie or play games. I liked galaxy s3 but after holding I felt I would drop it while using with one hand since I'm used to using Iphone. Many of us have small palm.

    This is so true. No argument. They just don't know the company's principle.

    I think what the poster meant was that the size is so you can operate the phone one handed (typing with one thumb). I don't think there's any phone out there that you can't type on with two thumbs.

    Aghhh, Apple apologists like you drive me crazy. I've owned an iPhone for 5 years and I am a short guy with small hands. A taller iPhone will be harder to use than a wider iPhone. When holding my phone with one hand my thumb easily reaches the 1/2" beyond the left and right side of the screen while it barely reaches the top as is. Sure I can stretch it, but it isn't a natural movement.

    Face it, this wasn't Apple designing the best phone for everyday use. This was design by committee. The engineers responsible for adding LTE needed more space so they wanted the phone bigger (because thicker wasn't an option). The App Store executives didn't want to break App Store compatibility so they kept the horizontal resolution the same to easily letterbox old apps.

    I mean come on, when the thing came out of the floor for the first time my first impression was "Who the heck brought the candybar phone?" It looks ridiculous.
  • Locateneil - Thursday, September 13, 2012 - link

    So you mean to say all phones with 16:9 aspect ratio are candybar phone? Including galaxy s3 etc? And about reaching top left or right corner, you can hold the iPhone bit above the bottom edges since width is unchanged but mainly the typing with one hand is great as before..
  • iLoveiOS - Friday, September 14, 2012 - link

    you use your thumb for typing dude. WTH.
  • menting - Thursday, September 13, 2012 - link

    being wider causing one to not be able to use their thumbs is just an excuse, because making it longer will have the same effect.
