When we envisioned the new iPhone, we landed on a remarkably thin and light design. But it’s nearly impossible to make a device so thin and so light without sacrificing features or performance.
We could have taken the easy way out and designed something more reasonable and less remarkable. But we didn’t. If the technology didn’t exist, we invented it. If a component wasn’t small enough, we re-imagined it. If convention was standing in the way, we left it behind. The result is iPhone 5: the thinnest, lightest, fastest iPhone ever.
iPhone 5 is just 7.6 millimeters thin. To make that happen, Apple engineers had to think small, component by component. They created a nano-SIM card, which is 44 percent smaller than a micro-SIM. They also developed a unique cellular solution for iPhone 5. The conventional approach to building LTE into a world phone uses two chips — one for voice, one for data. On iPhone 5, both are on a single chip. The intelligent, reversible Lightning connector is 80 percent smaller than the 30-pin connector. The 8MP iSight camera has even more features — like panorama and dynamic low-light mode — yet it’s 20 percent smaller. And the new A6 chip is up to 2x faster than the A5 chip but 22 percent smaller. Even with so much inside, iPhone 5 is 20 percent lighter and 18 percent thinner than iPhone 4S.
Thin, sleek, and very capable.
It’s hard to believe a phone so thin could offer so many features: a larger display, a faster chip, the latest wireless technology, an 8MP iSight camera, and more. All in a beautiful aluminum body designed and made with an unprecedented level of precision. iPhone 5 measures a mere 7.6 millimeters thin and weighs just 112 grams.1 That’s 18 percent thinner and 20 percent lighter than iPhone 4S. The only way to achieve a design like this is by relentlessly considering (and reconsidering) every single detail — including the details you don’t see.
More display means more to see.
Anyone can make a larger smartphone display. But if you go large for large’s sake, you end up with a phone that feels oversize, awkward, and hard to use. iPhone 5 features a 4-inch display designed the right way: it’s bigger, but it’s the same width as iPhone 4S. So everything you’ve always done with one hand — typing on the keyboard, for instance — you can still do with one hand. On a larger canvas that lets you see more of every web page. More of your inbox. More events on your calendar. Even more apps on your Home screen.
It’s more vibrant, too.
This isn’t just a larger display. It’s a larger Retina display. At 326 pixels per inch, it has a pixel density so high your eye can’t distinguish individual pixels. And as stunning as the Retina display is on the iPhone 4S, this one gives you 18 percent more pixels for an impressive 1136-by-640 resolution. Colors get a boost, too, with color saturation that’s 44 percent greater than before. So with iPhone 5, the games you play, the words you read, the images you see, and the apps you love look and feel incredibly vivid and lifelike. For big-time entertainment, iPhone 5 lets you watch widescreen HD video in all its glory — without letterboxing.
A breakthrough for ears everywhere.
Just like fingerprints, ears are unique parts of the body. Which means earbud headphones fit differently on everyone. So rather than use the speaker as the starting point for new headphones, Apple designers and engineers started with the ear. They tested over a hundred prototype designs on hundreds of people. All with the goal of creating earbuds that rest comfortably inside — and stay inside — a variety of ear types, while also producing quality sound. The result is a breakthrough for earbud headphones: Apple EarPods. They’re unlike anything you’ve ever seen or heard.
Enhanced audio on iPhone 5.
Apple EarPods are just the beginning of the improved audio experience on iPhone 5. It’s designed with three microphones: one on the front, one on the back, and one on the bottom. The front and back mics work together to achieve beamforming — a technique that helps iPhone focus on sound from the desired location for clearer audio. New noise-canceling technology reduces background noise. So when you hold iPhone up to your ear in a loud room, you hear what matters most: the voice on the other end.
