No surprise here, Apple gone official with its latest iPhone hardware, the iPhone 5s, with the 's' possibly standing for 'speed'.Because this isn't a radical upgrade. But it is a supercharging of the existing iPhone format. According to Philip Schiller, Apple’s senior vice president of Worldwide Marketing: 'iPhone 5s is the most forward-thinking smartphone in the world, delivering desktop class architecture in the palm of your hand. iPhone 5s sets a new standard for smartphones, packed into its beautiful and refined design are breakthrough features that really matter to people, like Touch ID, a simple and secure way to unlock your phone with just a touch of your finger.'At the heart of the new phone is the A7 chip, said to bring 64-bit desktop-class architecture to a smartphone for the first time, offering up to twice the CPU and graphics performance. So expect speedier app loading, better photo editing and the ability to play graphic-intensive games. According to Apple, you get all of that without the battery life taking a major hit.That is helped along by the new M7 motion coprocessor, which gathers data from the accelerometer, gyroscope and compass to offload work from the A7 for improved power efficiency. For developers (and eventually us), it also means better fitness and activity apps as the M7 motion coprocessor continuously measures your motion data, even when the device is asleep.The much talked about touchscreen sensor did indeed make the cut, going by the name of Touch ID. Built into the home button, Touch ID uses a laser cut sapphire crystal, together with the capacitive touch sensor, to take a high-resolution image of your fingerprint and 'intelligently' analyse it to provide accurate readings from any angle. All fingerprint information is encrypted and stored securely in the Secure Enclave inside the A7 chip and can also be used as a secure way to approve purchases from the iTunes Store, App Store or iBooks Store. Expect that to run and run as we see it in action.An all-new 8 megapixel iSight camera is also here, with larger f/2.2 aperture and a new, larger sensor with 1.5μ pixels for better sensitivity and low-light performance. Coupled with the new Camera app in iOS 7, it offers two-times faster auto-focus, faster photo capture, automatic image and video stabilisation, and better dynamic range. There is also a new Burst Mode, Slo-Mo video with 120 fps, a new FaceTime HD camera for better low-light performance and audio-only FaceTime calls with iOS 7.Also presents is an anodised aluminium body with diamond cut chamfered edges, a 4-inch Retina display and glass inlays plus three metallic finishes including gold, silver and Space Grey. iOS 7 obviously on-board, with the option to to 4G too - and not just with EE in the UK.Contract prices are to be confirmed, but if you want to go SIM-free, the price is £549 for the 16GB model, £629 for the 32GB model and £709 for the 64GB model.
