iPhone 5s Reviews

The new iPhone 5S is all about improvements under the hood as it keeps virtually the same design as the iPhone 5. But boy are those improvements big - the new iPhone 5S comes with a brand new Apple A7 chip, the first ever 64-bit chip on a phone. Not just that, Apple has made big changes to the iPhone camera adding a larger sensor and slow-motion video supper, and it has also included a fingerprint scanner right inside the home key.

Apple A7 is the first 64-bit mobile chip The new iPhone 5S features a brand new Apple A7, the first 64-bit chip on a smartphone. It comes with 32-bit and 64-bit compatibility, and Apple touts the chip to deliver double the performance in CPU and GPU performance. Apple brings OpenGL ES 3.0 support and that’s great news for gaming. Apple showed the third and last game in the Infinity Blade series and its graphics look mind-blowing. Along with the Apple A7, the new iPhone 5S features an M7 co-processor that always tracks the motion sensors - accelerometer, gyro, compass. This will enable more precise tracking and a new generation of health and fitness apps.

Advantages of iPhone 5s :

• New processors.

Apple’s senior vice president of worldwide marketing, Phil Schiller, said on stage that the new A7 chip in the 5S will be at least twice as fast as the iPhone 5. The chip will also run 64-bit architecture, making it “desktop class”.

There’s also a new suite of motion-tracking sensors routed through a separate chip named the M7, monitoring users’ movements and making the data available to third-party software. Apple promises this will “enable a new generation of health and fitness app” which is fairly standard hyperbole from the company, though the M7 should eliminate the need for consumers to buy separate health peripherals.

• The fingerprint scanner.

Biometrics might not be a particularly new feature, even on mobiles (Motorola’s Atrix 4G had one back in 2011) but it seems likely that Apple will popularise the technology, offering smooth integration and making mobile purchases more convenient. It won’t make the new iPhone ‘unhackable’ by any stretch of the imagination, but it will be a substantial barrier for criminals and will hopefully deter theft.

• A fantastic camera.

Like the HTC One, Apple’s new camera has gone for bigger pixels rather than more of them, with a 15 per cent larger sensor and a wider f/2.2 aperture. Apple have always been on top of mobile photography and the new iPhone looks like no exception. There’s also ‘True Tone’ flash that uses a dual, white and amber LEDs to create better colour balance; a new burst mode for taking multiple snaps at once, and slow-motion option on 720p video.

Disadvantages of iPhone 5s :

• Battery life.

It’s the one area of smartphone technology that is just crying out for innovation and Apple – along with the rest of the industry – have failed here. The batteries in the 5C and the 5S offer marginal improvement, with a couple of extra hours of talk-time and internet use, but it’s just not enough of a difference.

Apple have shown some sense in making the M7 processor handle motion data separately (this means less drain on the 5S's juice) but there's certainly more that could have been done. Google's Moto X for example has managed to squeeze more than a day's worth of power from a similar battery by introducing a host of minor improvements including Active Display (notifications that don't mean you have to unlock your phone) and dedicating processor cores to specific tasks (eg one for natural language tasks and one for 'contextual computing').
