iPhone 5s will replace the iPhone 5 at the top of the range. As Apple has practiced with the iPhone 3GS and iPhone 4s, this change will affect mainly to the internal components. The design of the device is almost no change, except by adding a third color, the golden (or champagne by the names) and some adjustments to the flash and the home button.

The changes most frequently cited:
o dual LED flash, instead of a simple flash for better pictures in the dark, long distance. Nothing exceptional property here. This technology

o found in many other smartphones, the Nokia N97 more than four years ago. A revised camera sensor. The iPhone 4s and iPhone 5 have a 8 megapixel sensor. Apple could stay 8 megapixels, while improving the quality of the sensor. In front, the latest generation of Android smartphones may have sensors over 20 megapixels, like the recent Sony Xperia Z1.

o new processor . It would be a smart dual-core A7, developed in-house by Apple. It is given as about 30% faster than the previous generation, the A6, which equips the iPhone 5. If this is the case, it will be less than 100% jump seen between other iPhone generations.

o fingerprint reader . This is the most visible change. Apple will leverage its acquisition of U.S. start-up AthenTec for $ 356 million in 2012. Housed in the home button, a fingerprint reader will likely unlock the smartphone without having to enter a password. Here is a picture of the button rele ased this morning by the Nowhereelse.fr site.

The process, which is called “Touch ID” in Apple’s interest to be more reliable than the various attempts in mobile and PC before. In consumer devices, fingerprint recognition is generally slow and unreliable. In addition to the release of the iPhone, other uses can then be imagined, especially in the online payment.

o extended with 4G compatibility. The iPhone 5s should be able to run on 4G networks all French operators in the frequency bands 800 MHz and 2.6 GHz. The iPhone 5 sold in France it is limited to frequencies in the 1800 MHz band, previously used only by Bouygues Telecom.

Among the uncertainties include the storage capacity can be up 128 GB, and the presence of the NFC.
