The first thing that makes a tangible difference is Touch ID, with a fingerprint scanner having made the iconic Home button its residence. The camera has a bigger sensor and dual LED flash, and gladly takes advantage of what's probably the most notable improvement - the 64-bit A7 chip. The iOS enters its 64-bit stage in its seventh iteration, well ahead of the competition. What this means is better memory management and more complex tasks and apps ahead. This could as well be the first step to bringing the iOS closer to Apple's dedicated desktop OS X - an early message that both platforms are due for a rendezvous eventually.
The iPhone 5s comes in a retail box that's exactly the same as the iPhone 5's from last year in terms of size and shape. Our Space Grey unit came in a white box, whereas last year's Black model came in a matching-color packaging. The box contents haven't changed either - you get the Apple lightning USB cable, an A/C adapter, EarPods headset with volume controls and microphone in their separate box and the SIM tray eject tool. There are a bunch of leaflets and, for the first time since the iPhone 4, Apple has thrown in two stickers.
The True Tone flash, which is essentially a dual LED flash, and the home button doubling as a fingerprint scanner are the only other differences over last year's flagship.
Then there's the new iSight camera. It has seen a sensor increase of about 15% - 1/3" up from 1/3.2" - without affecting the resolution. It's 8MP, just as before, but the pixel size has been increased from 1.4 Âµm to 1.5Âµm, meaning in theory each pixel will gather in more light due to its larger size. To help increase the light intake Apple has also increased the aperture from f/2.4 to f/2.2, while sticking with a 5 element lens.
Aperture is one of the three pillars of photography, the other two being ISO and Shutter speed Without a doubt, it is the most talked about subject, because aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus.
Apple decided that the 4" Retina from last year is still good enough by 2013 standards. The screen is an IPS LED-backlit LCD with a resolution of 640 x 1136 and 326ppi.
The battery inside the iPhone 5s is of slightly higher capacity, in view of the new 64-bit A7 processor. Last year's iPhone 5 went with 1440mAh, whereas this year we find a 1560mAh unit inside the iPhone 5s.

What does certified refurbished mean?The iphones are used abroad, taken back to Apple where they check to verify condition then re-sold as new. This normally happens because when Apple releases a new iphone in the market, users with the immediate previous iphone series are allowed to take it back to the apple store they purchased them at then trade-in for the new series by topping up some little cash.
