While attractive, capable new smartphones emerge regularly from competitors, a new iPhone deserves special attention for two reasons. First, the device lies at the center of a huge ecosystem of 225,000 apps, plus popular related gadgets like Apple’s iPod Touch connected media player and iPad tablet, which collectively are approaching 100 million units sold. Second, the iPhone’s multitouch, gesture-based interface; elegant Web browser; sophisticated music and video playback; and other features have been emulated on many competing devices, so what Apple does affects the whole industry.
I’ve been testing the iPhone 4 for more than a week. In both hardware and software, it is a major leap over its already-excellent predecessor, the iPhone 3GS.
It has some downsides and limitations—most important, the overwhelmed AT&T network in the U.S., which, in my tests, the new phone handled sometimes better and, unfortunately, sometimes worse than its predecessor. I’ll get into that below. But, overall, Apple (AAPL) has delivered a big, well-designed update that, in my view, keeps it in the lead in the smartphone wars.
The iPhone 4 is a dramatic redesign. It manages to pack a radically sharper screen; a second, front-facing camera; a larger battery; a better rear camera with flash; and a faster processor into a body that is 24% thinner, a bit narrower, and retains the same length and weight as its predecessor’s. In fact, Apple claims that the iPhone 4 is the world’s thinnest smartphone and sports the world’s highest-resolution smartphone screen.
With the front-facing camera, and clever new software called FaceTime, Apple has brought simple, high-quality video calling to mobile phones, albeit, for now, only over Wi-Fi and only among iPhone 4 owners. In multiple tests, this feature worked very well for me and is a classic example of the value of having one company do integrated hardware and software.
In addition, the iPhone now includes an updated operating system—which also can be installed free on the prior model—that introduces catch-up software features such as limited multitasking (the ability to run apps simultaneously); folders for grouping related apps; and, for email, a unified inbox for multiple accounts and the ability to present messages as threaded conversations. This software is called iOS4.
The iPhone 4 will cost the same as the iPhone 3GS: $199 for a model with 16 gigabytes of memory and $299 for 32 gigabytes, with a two-year contract from AT&T (T). The 3GS model will drop to $99 with a two-year contract and 8 gigabytes of memory.
Design
Physically, the iPhone 4 is attractive and feels great in the hand. Even the back is now clad in glass, which Apple claims is a superstrong variety 30 times tougher than plastic. I dropped it several times from a few feet onto a hard surface with no problem, and it acquired no scratches at all in my testing, even though I didn’t use a case or coddle it.
Although it is the same weight as its predecessor, the iPhone 4 feels denser and tighter—more like a fine possession than a disposable gadget. It still looks like an iPhone, but it manages to make the 3GS appear bulbous by comparison.
While its 3.5-inch screen, once considered huge, is now smaller than those on some other smartphones, the high resolution packs in a lot of material and makes text appear almost like ink on fine paper. The software is simply richer looking and smoother to use than on competing phones I’ve tested, with fewer confusing menus and settings, and far more apps.
Screen, Voice, Battery and Camera
Always brilliant at marketing, Apple has dubbed its new screen the “Retina display.” At a resolution of 960×640, it has four times the pixels of its predecessor and displays a whopping 326 pixels per inch. I don’t know how it compares with the human retina, but I do know that, just as Apple claims, text on the screen shows no jagged lines, even when expanded to giant size.
Voice quality was quite good, even on long speaker-phone calls, and data performance over Wi-Fi was excellent. Video and audio streamed from the Web played smoothly.
Apple claims longer battery life for most functions—seven hours of talk time, for instance, versus five hours on the earlier model. I didn’t perform a precise battery test, but, even in heavy use, the iPhone 4’s battery never reached the red zone on a single day of my tests.
The new rear camera is another big plus. My test pictures came out sharp and clear, even in low light and close-up situations. It isn’t the best cellphone camera I’ve tested, but it is a big improvement.
The iPhone 4 records video in high definition and, in my tests, these videos came out very well in most conditions. Apple also is selling for $5 an iPhone version of its Macintosh video-editing program, iMovie, for editing the videos.
FaceTime
Video calling is one of this device’s best features. As noted, it currently requires an iPhone 4 and Wi-Fi connection on both ends, though Apple says it is making the technology free to others and hopes to have millions of compatible devices. There is no setup and nothing to learn. You just press a FaceTime button, and if the other person accepts the invitation to talk face to face, his or her image appears, with your own image showing in a small corner window.
You can tap an icon on the screen to swap the front camera for the rear one, so you can show your caller around the room, or include other people near you who are behind the phone.
You can even begin a video call as an audio cellular call, push a button, and switch it to a Wi-Fi FaceTime call. It worked great for me, except for a couple of brief freeze-ups.
Multitasking
After years of complaints, Apple finally has brought multitasking to the iPhone. But it has done so in a limited way that won’t please everyone. On the iPhone 4, multitasking doesn’t mean every app can work fully in the background. To prevent a disastrous drain on battery life, Apple has allowed only certain apps to fully multitask. These include streaming audio services like Pandora, which keep playing music from the Web while you do other things, and voice-prompted navigation apps, which keep working while you’re on a call. Others that fully work in the background include Internet calling apps, and those that perform long downloads.
But some logical candidates, such as Twitter and Facebook, merely pause in place when you switch away from them. You can get back to them quickly, and they update more rapidly than before, but they don’t constantly update in the background. They only wake up in the background if you have set them to notify you of an update, and then only for a limited time. Apple says constant fetching of hundreds of social-networking updates in the background would kill the battery too quickly.
In fact, for many scenarios, such as games, Apple’s version of multitasking is really just fast switching among open apps that save their place. And, even to achieve this, the apps must be updated. For some users, this limited version of multitasking will be a disappointment.
To use multitasking you just press the iPhone’s home button twice and a row of icons representing running apps appears. Click on the one you want and, if it has been updated for the new operating system, it will appear just as you left it.
Multitasking also will work on updated iPhone 3GS models, but not on models older than that.
Folders
Because iPhone users can easily accumulate hundreds of apps, it can become difficult to organize them. So the new iPhone OS now allows you to group them into folders. For instance, I grabbed the icon for The Wall Street Journal app, dragged it on top of the one for the Washington Post app, and a folder was instantly created called “News,” based on the apps’ built-in categories. You can change the name to anything you like, or alter or disassemble the folders.
The Big Downside
The most important downside of the iPhone 4 is that, in the U.S., it’s shackled to AT&T, which not only still operates a network that has trouble connecting and maintaining calls in many cities, but now has abandoned unlimited, flat-rate data plans. Apple needs a second network.
Both Apple (AAPL) and AT&T (T) told me they worked to make the iPhone 4 do a better job with AT&T’s network. For example, the phone itself is surrounded by a prominent stainless-steel trim piece that acts as a large antenna. And Apple said it also tuned the phone to try to grab whatever band on the network was less congested or less affected by interference—to stress the quality of a signal over its raw strength. AT&T said it, too, made some changes to its network with the new iPhone in mind.
But, in my tests, network reception was a mixed bag. Compared with the previous model, the new iPhone dropped marginally fewer calls made in my car, both in Washington and in Boston, and was much louder and clearer over my car’s built-in Bluetooth speaker-phone system.
Yet, in some places where the signal was relatively weak, the iPhone 4 showed no bars, or fewer bars than its predecessor. Apple says that this is a bug it plans to fix, and that it has to do with the way the bars are presented, not the actual ability to make a call. And, in fact, in nearly all of these cases, the iPhone 4 was able to place calls despite the lack of bars.
However, on at least six occasions during my tests, the new iPhone was either reporting “no service” or searching for a network while the old one, held in my other hand, was showing at least a couple of bars. Neither Apple nor AT&T could explain this. The iPhone 4 quickly recovered in these situations, showing service after a few seconds, but it was still troubling.
Just as with its predecessors, I can’t recommend this new iPhone for voice calling for people who experience poor AT&T reception, unless they are willing to carry a second phone on a network that works better for them.
For everyone else, however, I’d say that Apple has built a beautiful smartphone that works well, adds impressive new features and is still, overall, the best device in its class.
