10 reasons to buy the iPhone 5S

New Delhi: Apple's next iPhone is finally here. The iPhone 5s carries over most of the features of the iPhone 5, but carries upgrades in terms of internals and some exterior hardware. The new smartphone will include the A7 processor, an improved camera with dual-LED flash, and a fingerprint sensor in the device's sapphire glass home button.Here we take a look at top 10 features of iPhone 5S that makes it an interesting buy:DesignThe iPhone 5S has the same design as the iPhone 5. The new smartphone now has two-tone back panel in new colors, carrying the same slim design we've seen before. But there's change in the home button. There's no rounded square icon in the middle of the button, but rather a ring around it. Fingerprint scannerApple has introduced a new fingerprint reader on the home button of the iPhone 5S, thus providing an extra layer of security to the device. The stainless steel detection ring can scan sub-epidermal skin layers, at 500ppi and is, incredibly just 170 microns thick. Due to the ring around the home button, it knows your finger is there and you don't have to tell it to scan. It's also integrated with iOS 7.In simple terms, the TouchID scanner is taking a high resolution picture of your fingerprint to analyze.New ProcessorThe iPhone 5S is all new on the inside, with the most notable change coming in the form of a new A7 processor. The A7 Apple-built ARM CPU will have a native 64-bit kernel, libraries and drivers. The A7 has 2x general purpose registers, 2x floating point registers, over 1 billion transistors and 100 square mm die size. The processor runs 32-bit and 64-bit apps.Apple says the new processor (A7) is twice as fast as the A6, with a 40x CPU performance bump. Graphics are said to be 56x faster. The A7 chip now has a brand new part called the M7, which is a motion sensor. It works alongside the A7 to continuously monitor motion from the gyroscope, accelerometer, and compass – helpful for new generation of health and fitness apps.CameraThe camera has been improved with a new Apple-designed lens with an f/2.2 aperture and a sensor that's 15 percent larger — it's still 8 megapixels. Each bigger megapixel lets in more light. Here's what's new:1.5-micron pixels on sensor, still 8 megapixels, sensor 15 percent larger than iPhone 5's5-element lens with f2.2 maximum aperture, increased from f2.410fps burst mode120fps slo-moBest shot selector for multishot and burstTrue Tone flash which white balances the color temperature of the the flash light during the shot, not the image in post-processingImage stabilization for stillsDynamic tone mapping, which automatically analyzes the scene and does local adjustmentsThese are really nice features which are made possible by the 64-bit A7 chip, which provides power for photo processing. The smartphone comes with a new flash called True Tone, with dual-LED. This is meant to take that whitish, blue tint out of photos taken with flash. One of the LEDs is the normal cool white and the other is warm amber. The new iPhone can combine them in over 1,000 ways to match the room and the skin tone, offering the best possible picture even in low light.The camera also offers image stabilization along with a new 10-shot burst mode.There's yet more with the camera: it has a 120fps 720p slow-motion video mode, and it does automatic motion reduction by analyzing multiple frames when you take a single shot.A new M7 coprocessorThe iPhone 5s' A7 processor is supported by a new M7 motion coprocessor that takes care of measuring motion data from the accelerometer, gyroscope, and compass sensors of the phone, and sending them to new fitness apps without waking up the A7 processor. It enhances the smartphone's battery life. It also recognises different types of motion.ColorsThe iPhone 5s comes in a gold version as well as grey (black) and silver. Experts say gold makes sense for the smartphone titan.A new FaceTime HD front-facing cameraThe iPhone 5s sports a new 1.2-megapixel front-facing FaceTime Camera that comes with a Backside illumination sensor (BSI sensor) for capturing low-light images and support for 720p HD video recording.Supports a large number of 4G LTE bandsThe iPhone 5S has up to 13 LTE bands, more than any other single model of a smartphone. This allows users to access high-speed Internet in more countries around the world. The new iPhone even supports Band 40, which is the same frequency band on which Airtel's 4G service has been deployed in India.Bigger batteryThe iPhone 5S will allow for 10 hours of 3G talk time, and 10 hours of LTE browsing. In contrast, the iPhone 5 claims to deliver 8 hours of talk time on 3G and standby time of 225 hours.Free bundled appsApple will also offer its premium iWork and iLife apps including Pages, Keynote, Number, iLife and iMovie, free to customers who buy the new iPhone 5s.
