0 Apple iPhone 5S officially unveils, Brings new A7 processor and Fingerprint sensor, prices starting from $649

Apple has announced the eagerly anticipated iPhone 5S in an event held at its campus . iPhone 5S is first of apple iPhone series device to be available in gold, Slate and Silver colours. It is powered with new A7 64 bit processor along with M7 Chip, first smartphone to be run on 64 bit processor. The iPhone 5S also brings an updated camera and revamped internals, read on to find out what the iPhone 5S is all about.

The A7 chipset

The Apple A7 is the first 64-bit mobile processor that has 2X the performance of the previous generation. The M7 on the other hand is a co-processor that can detect motion using a trio of sensors – Accelerometer, Compass and Gyroscope. Developers will be able to take advantage of it using their APIs.

What's more, regular apps will now have more information about things such as your mode of transportation. Thanks to the M7 processor, the Maps app, for instance, would be able to automatically switch to pedestrian mode as soon as you pull over your car and get out.

8MP camera

The new camera has a wider f/2.2 aperture (as opposed to f/2.4) and a 15% larger image sensor, which however is still 8MP. The larger surface has allowed for larger, 1.5 micron pixels (as opposed to the usual 1.4 micron ones). A larger camera sensor provides the benefit of lower image noise in low-light conditions and better tonal dynamic range in high contrast scenes.

There is also a new double LED flash on the iPhone 5s, which Apple has dubbed True Tone, called this way because it allows to achieve more accurate colors tone. It consists of two LEDs, with each having a different color temperature. By analyzing the scene, the iPhone 5s would decide what mix of the LEDs' color temperatures is needed to achieve a naturally lit scene. The dynamic mixing of the LEDs color temperature allows for up to 1000 variations of the light output temperature.

The camera also comes with new image stabilization, albeit digital one. It works by taking four photos with a short exposure time. Then the best parts of those photos are combined into one image with as little noise, subject motion, and hand shake as possible.

Slow motion video is also coming to the iPhone, with 720p 120 fps video capture. Pro Tip – Samsung just announced this for the Note 3 recently. The photo samples Apple showed at the Keynote looked really impressive, as usual.

Touch ID

iPhone 5s sports a touch sensor embedded into the Home button. It's called Touch ID.The Touch ID sensor is hidden behind a sapphire crystal lens. Around there is a metallic ring, which would detect the presence of your finger and activate the sensor without you pushing anything. It is 170 microns thin, senses 500 ppi and even scans your sub-dermial skin layers. The demo established that Touch ID is highly accurate.

Battery

Moving onto battery life, Apple stated that the standby time will be better than the iPhone 5 at 250 hours while you can do with 10 hours of browsing on LTE.

Price

As expected the iPhone 5s will be priced just as the iPhone 5 - in the US, at least, it will cost $200 for the inadequately equipped 16GB version, $300 for the overpriced 32GB version and $400 for the splurge 64GB edition.
The iPhone 4S 8GB will be heavily discounted and will be selling for free on a two-year contract. Sadly, the iPhone 5 will be discontinued, obviously to make way for the iPhone 5C.

Unlocked Apple iPhone 5S is priced at $649(Rs. 41,750) for the 16GB version, 749$(Rs. 48,200) for 32 GB and 849$(Rs. 54,616) for the 64 GB version.
