There was a time when there was much debate over the name of the next iPhone. Stuff even broke a story which featured a photo of a Vodafone inventory which had iPhone 6 in the listing. But as more rumours flooded in, it became pretty clear that we'd be seeing another S model iPhone – the iPhone 5S. And that has turned out to be the case.

For starters, the 5S is externally almost exactly the same as the existing iPhone 5, including the same 4in screen size. There are some notable differences, namely the larger flash (which means some iPhone 5 cases won't fit properly), the steel-rimmed Home button (more on that later) and the all-new colour finish option, but aside from those it's nearly indistinguishable from its predecessor.

The iPhone 5S will arrive packing an all-new quad-core A7 processor supporting 64-bit architecture. It's 56 times faster than the original 2007 iPhone and around twice as powerful as the iPhone 5's A6 CPU. It supports OpenGL ES 3.0 for extra graphical eye candy (particularly useful in high-end video games).

Alongside this A7 chip is an M7 coprocessor. Packed with sensors (accelerometer, gyroscope and compass), it's constantly collecting data that Apple promises will usher in a new generation of fitness and health apps. It's even doing so when the phone is in standby, saving battery power.

Battery power is in fact boosted quite notably, with Apple claiming a charge will deliver either 10 hours of talk time (over 3G), 10 hours of 4G web browsing, 40 hours of music playback or 250 hours of standby time.

The iPhone 5S's camera remains 8MP, but Apple has increased each pixel's size by 15 percent to offer enhanced light-grabbing abilities. There's also a larger F2.2 aperture, digital image stabilisation and an all-new dual-LED flash, all of which should greatly improve performance, especially in low light. The flash is dubbed "True Tone" and offers over 1,000 colour temperature combinations, the idea being to ensure skin tones remain realistic even in odd lighting conditions.

Apple has added a couple of software features to the camera too: there's the ability to shoot stills in a continuous burst mode (up to 10fps) and pick out the ones you like best (or have the phone do that for you); and you'll be able to capture HD video in 120fps speed in order for ultra-smooth slow motion playback.

The trusty Home button isn't going anywhere. It's just evolving, and it'll be a lot smarter in the iPhone 5S.

The key is the Touch ID sensor hidden beneath a surface of scratch-proof sapphire glass. This advanced fingerprint scanner can be used to unlock the phone and authorise iTunes purchases instantly. And if you're worried about hackers or, worse, government snoopers grabbing your fingerprint details for nefarious means, Apple says don't sweat it: the data isn't stored on their servers or in the cloud but on the phone itself. It also supports multiple fingerprints, so you can give access to friends and family if you wish.

The iPhone 5S will ship with iOS 7 as standard. The stripped-down OS has had itsskeuomorphic design obliterated by Sir Jony Ive, and it's got a refreshingly clean interface which streamlines the user experience. Plus, with iBeacon indoor navigation and support for game controllers, it's got plenty of new tricks to breathe a new life into the iPhone experience.

Some had predicted pricing in line with the iPhone 5, but Apple has upped things very slightly: SIM-free 16GB, 32GB and 64GB iPhone 5S models are £550, £630 and £710 respectively.

It's not cheap, certainly, but Apple is banking on those looking for a more affordable alternative turning to the new iPhone 5C, which starts at £470. An iPhone 4S 8GB model will also remain on sale, priced at £350.

You'll be able to buy the iPhone 5S (and all the new models) from 20th September 2013.
