Steve Jobs re-revealed iPhone 4, telling us about the remaining details. Here’s the exhaustive guide to all the features of the new iPhone 4.
The design
The hardware design hasn’t changed from the one we already knew about. It uses the same materials as the prototype: Black glass and stainless steel rim. It fits with the rest of the Apple product line, from the hard edges to the Dieter-Ramsesque utilitarianism of the iMac and the iPad.
The black glass is aluminosilicate glass. Apple claims this glass is “chemically strengthened to be 20 times stiffer and 30 times harder than plastic.” According to them, this makes it more scratch resistant and durable than the previous generation.
The size is smaller than the previous generation: 34% thinner than the iPhone 3GS. Although it is 3 grams heavier. According to Apple, it’s the thinnest smartphone ever. It has split buttons for volume, unlike the current iPhone 3GS, all made in stainless steel.
The stainless steel rim
The stainless steel rim gives the structure to the iPhone, and acts as part of the antenna for 3G and Wi-Fi. In theory, this will greatly increase the reception abilities of the new iPhone 4.
Physical size
The iPhone 4 is 4.5 x 2.31 inches, and 0.37 inches thick. It weighs 4.8 ounces (137 grams).
The hardware
The new big brain
It has an Apple A4 chip inside, just like the iPad. Inside the A4 there are a few interconnected chips: A Cortex-A8 main processor unit—the main brain—paired with a PowerVR SGX 535, which handles the high definition graphics of the new iPhone. These are directly connected with each other and two low-power 128MB DDR SDRAM chips. Since all these components are in the same chip, Apple claims the iPhone 4 can process data more quickly while consuming less battery than before.
The A4 also consumes less power because its sub-components can be switched on and off when they are not needed, shaving watts whenever it’s possible.
Battery life
The battery is 16% bigger than the current one. Coupled with the A4 processor and new display, it results in a longer battery life: Apple claims 40% more talk time. Here are their figures:
• Talk over 3G: 7 hours.
• Browsing over 3G: 6 hours.
• Browsing over Wi-Fi: 10 hours.
• Video: 10 hours.
• Music: 40 hours.
• Stand-by: 300 hours.
The display
The 3.5-inch multitouch screen has a resolution of 960 × 640 pixels. Apple calls is the Retina Display, and it has four times as many pixels as the current iPhone 3GS’ display. The screen has 326 pixel per inch resolution, a higher definition than your typical magazine, a quality that shows in the screenshot.
Apple claims that this IPS-based display—the same technology as used in the iPad—also has 800-to-1 contrast ratio which is four times better than the 3GS, with a higher viewing angle.
The apps will take automatic advantage of the increased relative resolution, which mean they will be a lot sharper for text, 3D graphics, and vectorial art. However, developers will need to include higher resolution bitmap images to make the app look perfect.
Like the iPhone 3GS and the iPad, the display has an oleophobic layer that makes it easier to clean.
The main camera
The new iPhone has a bigger sensor for the main camera. It’s backlit and has bigger lenses too. Instead of having a higher resolution, however, the sensor maintains the same 5 megapixel count. They are bigger dots, however, so it has a higher ISO—or sensitivity to light. That means that you would be able to take better photos and video in low light conditions, and your pictures will look a lot better.
The camera also has a LED-based flash, which works both for photographs and video. To focus, both for photographs and video—you just need to tap on the screen.
The video conferencing camera
In the front, there’s a video conference camera, with standard VGA resolution. This camera will be used with third-party applications, as well as Apple’s own video conference solution.
Gyroscope
The new iPhone 4 has a gyroscope built-in. This means that it can track movement with a very high precision, much higher than the built-in accelerometers in the previous iPhones. It’s 3-axis, so it’s capable of detecting pitch, roll, and yaw. Couple with the accelerometer, you have 6-axis motion sensing.
Other
• Like the iPad 3GS, the new iPhone uses the new micro-SIM standard.
• It has an additional microphone on the top used for noise cancelation.
The software
iOS4
The new iPhone 4 comes with iOS 4, a new moniker for the iPhone OS. The biggest new feature is, of course, selective multi-tasking, Apple’s way to multitask some application features without consuming too many resources and battery power.
The new iOS 4 supports Apple’s Retina display using resolution independence. This means that applications will automatically get scaled for the new resolution, but looking sharper, not pixelated. That includes typography, 2D vector graphics, and 3D graphics. However, developers will have to include higher resolution images for buttons or other screen controls (something that many have already, since this was already exposed in the last WWDC).
Video calling
However, the biggest feature of the new iPhone 4 is probably video calling, thanks to its front camera. Apple calls it FaceTime, and it works iPhone 4 to iPhone 4 over Wi-Fi—at least for 2010. Apple claims that in the future it will be available over 3G.
The iPhone 4 can use both cameras for video calling, so you can broadcast what is in front of you to another iPhone 4.
iMovie for iPhone
The new iPhone 4 will be able to use a new editing software from Apple: iMovie for iPhone. It comes with 1,500 new features.
The new iMovie for iPhone works on even 720p high definition. You can use it to cut the video clips, add automatic Ken Burns effects for still images and a music soundtrack taken from your iPhone’s tunes. After you are done with your movie, you can export it to 360p, 520p, and 720p.
It’s a separate application, however, it doesn’t come built-in with the iPhone 4.
iBooks
iBooks will also be available for the new iOS4. Apple claims that the new iPhone 4′s 325 pixel-per-inch display will make the books perfectly readable. It will use the same controls as the iBooks application in the iPad.
Price and availability
The Phone 4 will be available in black or white on June 24, and will cost $199 and $299 for 16 and 32GB if you are a new user or you are eligible for an upgrade.
If you are an existing iPhone user, the early upgrade will cost you $399 and $499. Without contract, the iPhone 4 is $599 and $699.
Apple, Antennagate, and Why It’s Time to Move On
“There’s an awful lot of hoopla about that iPhone antenna.” Why yes, there is. And while there’s much to criticize about Apple’s response, we’re glad to see they’ve stopped pretending the problem doesn’t exist.
Apple spent most of the time last week defending the iPhone 4‘s antenna, using both data and rhetoric that was impressive in its scope.
Defense No. 1: Life Sucks
Apple’s primary defense is that every phone‘s reception sucks when you hold it. The company line from the very beginning: “Gripping any mobile phone will result in some attenuation of its antenna performance, with certain places being worse than others depending on the placement of the antennas. This is a fact of life for every wireless phone.”
Apple showed this “fact of life” using three non-iPhones in particular: the BlackBerry Bold 9700, HTC Droid Eris and Samsung’s Omnia 2. The phones are death gripped; the bars plummet.
It’s true, you can readily demonstrate attenuation on a lot of phones. Just the handful of phones at my place, where I have mediocre coverage, show that. Gripping the Nexus One on the bottom causes a bar to drop; the BlackBerry Bold 9700 drops three bars, precisely as demoed by Apple; neither the Droid X nor the Evo drop any bars held with a normal death. (You have to hold the very top of the Droid X or Evo to knock off a bar.) The iPhone 4, upgraded to 4.0.1, touched in the single weak spot, drops 2 bars.
The difference is that the other phones, with the exception of the Nexus One, require a grip—your hand has to wrap around where the antenna is located to cause noticeable attenuation, while touching the iPhone 4 at a single point disrupts the signal. (As RIM and Nokia were quick to reply when Apple singled them out.)
Which is exactly what Ryan Block asked Apple’s Bob Mansfield about at the post-conference Q&A:
Q: How does touching the corner with a single finger seem to cause this issue? It’s not just a grip, it can just happen by touching a single finger.
A: Your body is a pretty effective signal absorber. When you make contact with that phone, its performance in contact with you is less than its freespace performance. It’s a way to attenuate the signal by some amount.
Then why would cases, which you wrap your hand around, be a working solution to the problem? As an engineer told us, the fact that bumpers are the solution shows that the real problem has to do with skin contact with the iPhone 4′s antenna—not attenuation simply from signals passing through your body. Rather, he suggests, it seems like the antenna’s impedance is changing as a result of the skin contact, so it’s possible that a thin electrically non-conductive coating could solve the problem. (Perhaps this is why Steve promised to re-evaluate the issue in September.) That’s why the other phones don’t have a signal loss from attenuation that’s quite as profound.
It’s also why Steve Jobs offered his own “pet theory”: that not enough cases have been sold for the iPhone 4. That seems a little silly, as the iPhone 3G and 3GS didn’t have a single weak point, affected by skin contact.
Defense 2: Everything Is Just Great
The iPhone 4 is using “a very advanced new antenna system.” In fact, Steve says it “is a more advanced antenna than ever has shipped on a smartphone before.” And, later he says, “looking at the data, we don’t think we have a problem.” What data is that?
Well, they’ve spent $100 million on a very fancy facility with 17 different antenna characterization chambers to test phones.
Only 0.55 percent of all iPhone 4 users have called AppleCare about the antenna or reception. (This includes Genius Bar visits, apparently.) That’s around 16,500 complaints, out of 3 million iPhones sold. “Historically for us, this is not a large number,” Steve says. (What is a large number then? A normal number? He does not say.)
For comparison, HTC says that the Droid Eris—one of the phones Apple used to show that attenuation screws every phone—has fielded reception or antenna complaints from just 0.016 percent of all users. (It’s possible that it’s harder to find where to complain about the Eris.) Oh, and the return rate for the iPhone 4 is just 1.7 percent, versus 6 percent for the iPhone 3GS. Happy campers!
But then there’s this: “I can tell you since we’re being totally transparent, that even though we believe the iPhone 4 antenna is superior to that of the iPhone 3GS, I must report to you that the iPhone 4 drops more calls per 100 than iPhone 3GS.” The rate of iPhone 4 dropped calls is less than 1 additional dropped call per 100 than the iPhone 3GS.
That number is fuzzier than it seems, too. Converting that to a percentage, less than 1 additional percent could be anywhere from .01 percent to .99 percent. Presumably, Steve would use the smallest number possible—something like less than one half of one percent. So let’s round up to one percent. Adding another percent to 100,000 dropped calls is an additional 1,000 dropped calls. Or, put a more damning way, and flipping back to the way Steve framed it, if the iPhone 3GS dropped 1 out of every 100 calls, the iPhone 4 could drop up to 1.9 out of every 100 calls—it’s possible we’re talking a nearly double dropped call rate.
Still, it’s a pretty curious thing. Shouldn’t the iPhone 4′s “very advanced antenna” result in fewer dropped calls, not more, especially if it’s superior?
Defense 3: We Made a Little Mistake, We’re Being Exploited, But Now Everything Is Fixed
If you want to boil it all down, Steve says, “The heart of the problem is: Smartphones have weak spots. We made ours extremely visible. Some took advantage of that to demonstrate it. It was very easily demonstrable. We screwed up on displaying too many bars and made that demonstration more theatrical than it needed to be.”
Apple says they’ve been incorrectly displaying the bars, so they’ve fixed it. “We screwed up on our algorithm…Our choice is to put the correct algorithm in, which we’ve just done.” It’s true, they have corrected a real issue, as Anandtech beautifully shows. The iPhone’s signal bars painted a much rosier picture of the signal situation than reality, and the compressed dynamic range of the bars made them only slightly more accurate than licking your finger and sticking it in the wind. They’re now far more meaningful and evenly distributed indicators of signal than they’ve been for the last two years. But why didn’t Apple do this sooner, if it was so terribly wrong?
Well, originally it made the iPhone’s reception look better, that’s why. It stretches credulity to super-spandex levels to think it slipped by Apple’s engineers for years, undetected. (After all, they’re making the most advanced antennas in any smartphone, with $100 million testing facilities. They didn’t notice the iPhone used a juiced signal indicator?) The flipside of pumping the bars, what came back to bite Apple, was that the signal drops looked worse than they actually were.
There’s a weird subtext about transparency and victimization through all of this, too. A sense of, “See what happens when we’re transparent?” Apple’s not known for being very open, so it’s interesting that when Steve talks about the pains they’re taking to be transparent more than a couple times—”we went through a lot of trouble to put this beautiful line in the steel” to mark the weak spot—it’s interspersed with comments like the one above and “When people are criticizing us, we take it really personally. Maybe we should have a wall of PR people keeping us away from all that.” As a journalist, this is laughable: Apple has one of the most opaque and impregnable walls of PR people in the industry. Apple’s silence, enforced by PR staff who will clam up at the slightest hint of someone going off-message, are legendary.
That’s why you’ll never get a straight-up apology from Apple. They’re smart enough to know that would open the door to a class action suit and too proud to throw themselves on their sword over a single irritating-if-minor issue. It’s just not their style and never will be while Jobs is in charge.
Defense 4: It’s a Little Problem
See all those numbers? It’s a little problem. We work hard. We love you. We make great stuff. We’re giving out free cases. Stop talking about this. Steve says, “We’ve been working really, really hard for the last 22 days to try to understand what the real problem is, so that when we solve it, we actually solve it, rather than just putting a bandaid on it.”
This elides the fact that cases are a bandaid. Almost literally—it’s a piece of material affixed at top a gaping hole in the phone. There is a problem when people’s skin comes into contact with the weak spot on the phone. On every single iPhone 4.
The Upshot
So! There is a problem with a particular point on the iPhone 4′s external antenna. When you touch that single point with bare skin, you lose signal strength—around 24dB, to precise. The old method of displaying signal bars did made it look worse, because of the way it compressed the dynamic range. The free cases will help—significantly, according to Anandtech’s numbers, but it’s not a permanent fix. The vast majority of the time, it does offer better reception.
Apple’s done the right thing, for now, by fixing the iPhone’s signal display, which might be the best of any smartphone—even if it’s a little ridiculous that this is what it took for that to happen. And the free cases do ameliorate the antenna problem, even if they don’t fix its cause. Maybe, as Jean-Louis Gassee suggested, it should’ve been framed as a tradeoff from the very beginning. Informed consumers, radical transparency, crisis averted. Everyone would’ve talked about how much they love their iPhone anyway from the very beginning.
The iPhone 4 is a fantastic phone—among the best yet made—and the antenna issue may dent its crown, but doesn’t dethrone it.
