iPhone 4S

Dual-core A5 chip.
The most powerful iPhone processor ever.
Two cores in the A5 chip deliver up to two times more power and up to seven times faster graphics.1 And you’ll feel the effects. Fast. iPhone 4S is quick and responsive, which makes all the difference when you’re launching apps, browsing the web, gaming and doing just about everything. And no matter what you're doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life.

Shoot stunning 1080p HD video everywhere you go. With all-new optics, the light is always right, the colour is always vivid and everything will look even better than you remember. Video stabilization steadies shaky shots. And you can edit video right on iPhone and share your lush life as fast as you shoot.

Retina display.
Clearly remarkable.

The sharpest, most vibrant thing you’ll see on iPhone 4S is everything. The Retina display is the highest-resolution phone screen ever. In fact, the pixel density is so high that the human eye is unable to distinguish individual pixels. But without a doubt, you’ll notice crisp text, sharp graphics and stunning images. It’s more remarkable than the printed page. And you’ll be completely absorbed.

iCloud. Your content. On all your devices.

iCloud is the easiest way to manage all your stuff, because it manages it all for you. iCloud stores your music, photos, apps, mail, contacts, calendars, documents and more. And wirelessly pushes them to all your devices. It’s automatic, effortless and seamless. And it just works

FaceTime. It’s even better face-to-face.

FaceTime lets you hear a voice and see the face that goes with it — iPhone to iPhone, iPad 2, iPod touch, or Mac over Wi-Fi.4 So no matter where they are, no matter where you are, you’ll always be there. Making a FaceTime call is just as easy as making a phone call. You’ll never miss a big event, an important meeting, or a good laugh.
