Overview

The iPhone 4S is the much anticipated successor to the iconic iPhone 4. It builds up on it’s predecessor’s legacy with a dual core CPU, better RAM, a more polished OS with new features and a slight yet hard-to-notice tweak in design. The iPhone 4S sits rightly at the top of Apple’s smartphone throne.

One of the key elements that are highlighted by the company for its new device is the addition of Siri, a personal digital assistant that can take commands and execute tasks for you on the go while connected to the internet. The service essentially creates an artificial intelligence that gets increasingly tailored to your specific needs and can understand routine conversation.

We are pretty sure you are wondering just like we are, in the battle of the iPhones, which one comes out on top? We have made it easy for you to see the difference one by one.

1. CPU – The 4S has a dual-core CPU while the older version has a single core unit.
2. Camera – The camera in the newer version has been bumped up to 8 MP from the 5 MP of the previous iPhone.
3. Video - The new iPhone is now capable of 1080p HD video compared to the 720p of the iPhone 4.
4. Weight – The newer iPhone has gained 3 extra grams over the original iPhone 4.

That is all, in every other way, including display, talk-time,secondary camera etc, both the devices are exactly the same.

The dual-core A5 chip delivers even more power. The 8MP camera with all-new optics also shoots 1080p HD video. And with Siri, iPhone 4S does what you ask. Talk about amazing.

Siri. The intelligent assistant that helps you get things done. All you have to do is ask.
Now you can use your voice to use your iPhone. Just talk to Siri as you would to a person: "Do I need an umbrella?" or "Any great burgers around here?" or "Where's the closest ATM?" Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.

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.2 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.

iPhone 4S is great for gamers. The A5 chip pushes graphics up to seven times faster. So games run smoother and they're even more realistic. And graphics-intensive apps perform even better.

The you-can't-believe-it's-on-a-phone camera.
This just might be the best camera ever on a phone. And with all-new optics, it just might be the only camera you need. Because behind every shot, you've got 8-megapixel resolution and a custom lens with a larger f/2.4 aperture. Not to mention an improved backside illumination sensor, excellent auto white balance, advanced color accuracy, face detection, and reduced motion blur. It all means that no matter how many people, how much light, and how much action you capture, everything looks exactly as it should. And just wait until you see the photos.

The iPhone 4S camera gives you 8 megapixels - that's 60 percent more pixels than the camera on iPhone 4. And they're engineered with a higher, full-well capacity to collect even more light. With more megapixels and more light, you'll see a dramatic difference in the resolution and details of your images.

Video recording. In 1080p amazing HD.
Shoot stunning 1080p HD video everywhere you go. With all-new optics, the light is always right, the color 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.

Record amazing 1080p HD video at 30 frames per second. The advanced backside illumination sensor and larger aperture let in even more light. Improved auto white balance makes color even more accurate. And temporal noise reduction helps you take great videos in low light.

iOS. The world's most advanced mobile operating system. And the easiest to use.
With every iOS advancement come even easier ways to do everything. That's what makes iOS years ahead of anything else. iOS 5 leaps even further ahead, bringing over 200 new features to iPhone 4S. Here are just a few of our favorites.

Cloud. 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.

With iCloud, the music you buy in iTunes appears automatically on all your devices. You can also download your past iTunes purchases. So your music collection goes where you go.

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.

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.⁵ 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. And it's even easier with Siri. Just tell Siri "FaceTime with Mom" and you show up, smile, and wave hello. You'll never miss a big event, an important meeting, or a good laugh.

AirPlay. From the small screen to the big screen
With AirPlay, you can wirelessly stream what's on your iPhone to your HDTV and speakers via Apple TV.6 And with AirPlay Mirroring, whatever you see and do on your iPhone appears on your HDTV at the same time.

AirPrint.
Print everything wirelessly.
Print your email, photos, web pages, and documents right from your iPhone over Wi-Fi.7 There's no software to download, no drivers to install, and no cables to connect. With just a few taps, you can go from viewing something on the iPhone screen to holding a printed copy.

Built-in apps. They do just about everything. So you can, too.
You'll do everyday things in extraordinary ways on iPhone 4S. Take amazing photos and shoot HD video. See your friends and family with FaceTime. Browse the web on the Retina display. Check email. Send messages. Set reminders. Check calendars. Or just ask Siri to help you get things done - it figures out the right apps to use.

Call it better, faster, and even more worldly.
iPhone 4S is the first phone to intelligently switch between two antennas to transmit and receive, so call quality is better. It also doubles the maximum HSDPA data speeds to 14.4 Mbps.8 Which means faster connections, faster loading and reloading, and faster downloads. And iPhone 4S is a world phone, so you can use it almost anywhere. Whether you're a GSM or CDMA customer, you can roam GSM networks in 200 countries around the world.

Maximum Data Download Speeds (HSDPA)
iPhone 4S: 14.4 Mbps
iPhone 4 :7.2 Mbps
