iPhone 5s is the first smartphone with 64-bit technology, providing blazing-fast performance when launching apps, editing photos, or playing graphic-intensive games. iPhone 5s features an all-new 8-megapixel iSight camera and introduces the Touch ID fingerprint sensor, which allows you to securely unlock your phone with the touch of your finger. iPhone 5s comes with iOS 7, the most significant iOS update since the original iPhone.

“iPhone 5s is the most forward-thinking smartphone in the world, delivering desktop class architecture in the palm of your hand,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing. iPhone 5s comes in gold, silver, or space gray.

iPhone 5S is Apple’s flagship phone and it’s the best iPhone you can buy. It looks exactly like how the iPhone 5 looked last year but with improved internals and guts that will make everything run even faster. Twice as fast, Apple says.

One thing is new though. The iPhone 5S now has a new gold color option, along with the usual black and white (which is now weirdly called space gray—it’s a lighter hue compared to the black 5—and silver).

The Spec’s

Powering the iPhone 5S is Apple’s new A7 processor which is a 64-bit chip. It’s the first 64-bit chip in a smartphone and it’ll make the iPhone 5S two times faster than the iPhone 5 (and 40 times faster than the original iPhone). The 5S runs OpenGL ES 3.0 which makes the graphics performance in the 5S pretty gnarly too (that’s 56x faster than original iPhone, which yay, I guess?). The A7 chip has 3x general-purpose registers, 2x floating-point registers and over a billion transistors.

Along with the A7, Apple is using a “motion coprocessor” in the 5S called the M7. It continuously measures motion data with an accelerometer, gyroscope and compass support. It’s supposed to “enable a new generation of health and fitness apps” by letting apps use all that motion data without tapping into the A7.

Fingerprint Scanner

Just as we expected, the iPhone 5S’ home button pulls double duty as a fingerprint scanner. Apple dubs the feature “Touch ID.” The scanner adds another layer of security to your iPhone by allowing you to use the fingerprint scanner in lieu of a passcode. Place your thumb down on the new sapphire crystal home button and the iPhone 5S will unlock. The silver ring around the home button will detect when your finger is on it so you don’t have to actually press down on the button.

You can use Touch ID to make purchases in iTunes too and set it up so it can read multiple fingerprints.

The fingerprint sensor has a 500ppi resolution and 360 degree readability.

Camera

As with every new iPhone, Apple focused on making the camera even better. The iPhone 5S has dual-LED flash that might make the flash on the iPhone camera actually usable. Or at least, slightly better than the weak excuse of a bulb that did more harm than good in previous iPhones. The dual-LED flash—one is white and the other is amber—in the 5S may help make your pictures look more natural and balanced because the iPhone can combine the right percentage and intensity of the two bulbs to create 1,000 different variations of a flash.

Megapixel-wise, the camera remains the same at 8-megapixels. But megapixels never tell the entire story with cameras. The iPhone 5S has improved its camera by using a larger f/2.2 aperture and a 15 percent larger sensor. Basically, that means the camera has 33 percent greater light sensitivity, which will make for better looking pictures.

The 5S camera has an autofocus that’s twice as fast, auto image stabilization, and a new burst mode to capture ten frames per second. The iPhone will analyze all those burst shots and show you what it thinks your best shot is. The iPhone 5S also has a slow-motion camera that allows it to record 720p video at 120FPS. Your videos of your cat will theoretically look more epic.

Battery Life

The iPhone 5S has slightly better battery life with ten hours talk time, ten hours LTE browsing, and 250 hours standby. That’s an improvement over last year’s eight hours of talk time, eight hours of LTE browsing and 225 hours of standby. We’ll have to see how this actually translates in real world use though.

Accessories

Apple is in the accessories game. It’s selling a dock again for $30 which will fit both the iPhone 5S and the discontinued iPhone 5. There’s also a new leather case that comes in six different colors, which will run you 40 bucks.

Price and Availability

Apple is keeping the same price as the previous generation for AT&T, Verizon and Sprint. The iPhone 5S 16GB will cost $199, the 32GB version will be $299 and the 64GB version will cost $399, all with a new two-year contract. There’s also an unlocked and contract-free version of the 5S for T-Mobile. Prices for the unlocked 16GB start at $650.
