he Iphone 5s is Apple's 7th generation
Iphone. Iphone 5s was introduced at Iphone event by Phill schiller on September 2013 and released September 2013 by ios 7 looked identical to the previous Iphone 5 including the 1136X640 in cell display. With this Iphone however, there is one significant exception, the iphone 5s does not only come in dark and light colours, space grey and silver, but also has gold colour available.

The iphone 5s comes with a fingerprint and touch id, which is also called biometric authentication to authorise purchases from itune store, appstore and ibookstore. It works with capacitive sensor that detects your finger print, snaps a high resolution of it and sends information in form of mathematical harsh to the A7 chipset for processing.
The 4G LTE radio now handles more band in more places than ever before, while apple didn't add 802.11ac networking to the 5s, they did add multple in/multiple out to make the 802.11n networking firmly establised.

Iphone 5s is powered by 64bit A7 chipset, it is the first 64 bit SOC on the market. The A7 chipset includes a 1.3GHZ dual core custom cyclone processor based on ARM v8 instruction set and a open GL 3.0 -equiped power vR G6430 graphic processor.This implies that iphone 5s is one of the most advanced devices and can run most complex applications at a faster rate. The apple A7 processor includes apple M7 co-oprocessor, the M7. The M7 collects all motion related data - accelerometer, gyroscope, magnetometer, etc. in the background and shares it with ios and apps.

On paper, the camera on the iPhone 5S looks much similar to the one of iPhone 5. Both have 8-megapixels, but Apple has made some significant chnages  to the iPhone 5S camera to enable better efficiency  in low-light conditions  where traditionally  iphone cameras are weak.

In her bid to get more light into the lens by enlarging the sensor from 1/ 3.2 to 1/ 3, which in turn leads to an increase in the size of the pixels from 1.4 microns to 1.5 mircons. It's a similar method to that attempted by the HTC One, albeit with mixed results due to its extremely low 4-megapixel resolution, half that of the iPhone 5S.

The 5S shot on the left has fewer shiny, harsh light reflections, while the hair colour is more natural and accurate. It's by no means a revolution in flash photography on a phone, not least as the range is still much the same, but it does diminish the worst imperfections caused by pure white LED flashes.
In well illuminated  conditions the camera performs well. Colour is accurate and there's enough detail. There is not optical image stabilisation, such as can be found on the Nokia Lumia 1020, but the iPhone 5S uses software stabilisation to compensate somewhat for shaky hands.

Video performance is also solid, with a few nifty additions. A slow-motion mode has been added and it's bundles of fun. The new camera and app allows shooting at 720p 120 FPS. Once you've finished shooting you can move some sliders around and make any section move in slow motion. It's simple but it works extremely well. Bouncing on a trampoline will never look more elegant.

The myriad tweaks Apple has made to the camera of the iPhone 5S make it one of the best all-rounders out there. With a phone of  improved camera app that's easier to use and adds a few nice new features such as photo filters. It's hard to say it's the best phone camera around as the definition varies depending on your needs, but it's right up there.
