Every thing you need to know about the iPhone 5s

Iphone 5S

Apple is calling the 5s its most “forward-thinking” phone. Though its aluminum body is almost the same as the iPhone 5’s, there’s a bunch of new hardware inside. Most impressive is the new a7 processor, which apple touts as the first 64-bit processor available in a smartphone. The 5s also includes a new M7 ‘motion coprocessor’; some big camera upgrades and capabilities; and the Touch Id fingerprint authentication system. (More on these below.) Other improvements over the iPhone 5 include a slightly larger battery, expanded carrier support, and new colour choices.

The new A7 processor

The a7 chip inside the iPhone 5s is unquestionably the most powerful chip apple has ever put in a mobile device. It’s also the first smartphone to use a 64-bit architecture – usually found only on laptops and desktop computers. The implications of this might not be immediately  apparent, because apps have to be written to take advantage of it. But down the road, the new processor will offer some exciting possibilities for expansion and power. The a7’s support for the latest OpenGL ES 3.0 standard means better graphics performance, too. In fact, apple claims that it’s twice as fast at both processor-intensive and graphics- intensive tasks as its predecessor.

The M7 coprocessor

The iPhone 5s also includes a separate processor, called the M7, that handles sensor data. The M7 – which apple calls the motion coprocessor – is a brand-new chip that complements the a7 by handling data from the device’s many sensors, including the accelerometer and compass. Why a separate processor for all that? The key to the M7 is that it can log data from those sources without waking the full a7 processor. This means that not only can fitness-tracking apps run more easily in the background, but they’ll also use up less of your precious battery power. and using the new Core Motion API, third-party apps can use real-time location and motion information – like,
say, whether you’re walking or riding in a car – to determine how the app behaves, without dramatically effecting battery life. There’s an implication here for wearable technology and the rumored iWatch.









The camera

If apple’s specs and feature list are any indication, the 8-megapixel camera in the 5s should offer noticeably better performance, along with some useful new capabilities. For starters, the 5s uses a new, five-element lens that  Apple designed specifically for the new iPhone. This offers an f/2.2 aperture, a 15-percent-larger area than the 5’s lens, and 1.5-micron pixels.
The device also includes a new dual-LED True Tone flash that Apple says is the first of its kind on a phone or a standalone camera. One flash is cooler white, while the other is amber with a warmer colour temperature. The handset monitors ambient light and then frees the two flashes together to match that light. Together, Apple says, the two flashes provide more than 1000 unique light combinations, for flash lighting that’s brighter and more natural.
But iOS 7 also includes a bunch of software specifically designed to take advantage of the improved camera hardware. For example, before you take a photo, the phone automatically adjusts the white-balance and exposure to create a tone map for better highlights and shadows; it also performs auto-focus Fingerprint control the touch ID sensor on the 5s will help stop unwanted access.

matrix metering for improved sharpness. When you take the photo, the phone actually takes multiple images, analyses them in real-time, and then shows you what it thinks is the best one.
The 5s also includes image stabilization in software. In situations such as low lighting where you’d normally end up with blurry images, the phone takes multiple photos with a single shutter press, and then blends them together
into a single, sharp image. And a new burst mode captures 10 full-resolution frames per second for as long as you hold down the shutter button. But unlike most burst modes, on an iPhone 5s, the phone automatically filters out bad shots to show you only the ‘best’ ones. (You can choose others manually, if you like.)
When taking video, you can capture 720p video at 120 frames per second, slowing it down later for true slow- motion video. (You can do the editing in your favorite video app, or you can choose, right in the Photos app, which section of the clip to view in slo-mo.) And Panorama mode now allows you to adjust exposure as you pan.

Touch ID fingerprint sensor



This is a capacitance-based (as opposed to optical) scanner that’s built into the Home button. The ‘capacitance’ part means that instead of taking a visual scan of your finger or thumb, the scanner detects minute differences in electrical charge caused by a fingerprint’s whorls, loops and curves.
The phone then produces a digital template (again, not an image) based on that scan. In other similar systems, software then runs such a template through a cryptographic hashing process, making it virtually impossible to recreate the original print from the template. If that’s how Touch ID works, the hashing process should make it harder – if not impossible – to spoof your prints. For further security, your fingerprint is Picture this the 5s’ camera has some useful new features. never stored in the cloud or anywhere in the phone’s memory – only in a secure area of the A7 chip itself. We don’t yet know all the details about how iOS 7 will use the fingerprints it detects. But we do know that it will let you bypass the lock screen passcode. It will also let you authenticate a purchase on the App Store using your finger.

Battery life

Apple claims that the 5s offers battery life equal to or greater than that of the iPhone 5. Specifically, the company says the 5s offers 10 hours of 3G talk time, 10 hours of LTE or Wi-Fi browsing, or 250 hours of standby time. Compare that to Apple’s claims for the iPhone 5 when that model was released: eight hours of 3G talk time, 10 hours of Wi-Fi browsing, or 225 hours of standby time.
According to Apple, the 5c’s battery life is identical to that of the 5s. We’ll, of course, thoroughly test each model’s battery life in the coming weeks.

Storage options

The 5s is available in 16GB, 32GB and 64GB versions. There had been some expectation that Apple might offer a 128GB version of the iPhone, but this wasn’t the case.
For many the extra storage offered by the 5s will be the deal breaker. However, with iCloud, and the potential offered by external storage devices, you may not need as much storage as you think.

Pricing

Of contract pricing for the 16GB 5s is £549, while a 32GB model will set you back £629 and the 64GB option costs £709. Obviously, you’ll need to factor in the monthly outlay of whatever contract or pay-as-you-go deal you opt for.
