Apple iPhone 5S

It is September 2013, and Apple has just released the ‘S’ that stands for ‘Sensors.’ While it looks virtually identical to the iPhone 5, the iPhone 5s is a technical revolution masquerading as a minor update. It’s finished in a new ‘Space Grey’ and a surprisingly classy ‘Champagne’ gold that has instantly become the must-have accessory in London and beyond. At 112g, it remains a featherweight champion of the ‘glass and aluminium’ world, but the real technical genius is located behind the new sapphire crystal Home button._x000D_

The headline innovation is Touch ID. By integrating a 500-ppi capacitive fingerprint sensor into the Home button, Apple has solved the greatest technical friction in mobile history: the passcode. It’s not just a gimmick; it’s a seamless, 360-degree biometric system that works with an accuracy and speed that makes the competition’s swipe-based scanners look like Stone Age tools. Under the hood, the 5s is the world’s first 64-bit smartphone, powered by the A7 chip. This isn’t just marketing hype; it’s a ‘desktop-class’ architecture that doubles both CPU and graphics performance, enabling a level of visual fidelity in games like Infinity Blade III that was previously the sole domain of consoles._x000D_

But the 5s isn’t just about raw power; it’s about efficiency. It features the M7 motion coprocessor, a dedicated bit of silicon that continuously monitors data from the accelerometer, gyroscope, and compass. This allows the phone to track your fitness and movement without waking the main A7 chip, preserving the 1560 mAh battery. On the imaging front, the 8-megapixel ‘iSight’ camera has a 15% larger sensor and a wider f/2.2 aperture. It introduces the ‘True Tone’ flash, a dual-LED system that mixes warm and cool light to prevent the ‘ghostly’ look of traditional mobile flashes. It also features 120fps ‘Slo-mo’ video, which has immediately turned every UK pub session into a cinematic event._x000D_

The screen remains the 4-inch Retina Display (1136 x 640), which is starting to feel a bit dainty compared to the 5-inch giants of the Android world, but its colour accuracy and clarity are still world-class. Connectivity is comprehensive with 4G LTE support for all UK networks, Wi-Fi, and Bluetooth 4.0. The only technical sting is the battery life; while the A7 and M7 chips are efficient, the 5s is still a ‘charge every night’ device, especially if you’re hammering the new ‘Touch ID’ and 4G data. The iPhone 5s is a sophisticated, forward-thinking masterpiece, a phone that brought biometric security and 64-bit computing to the masses in a package that fits perfectly in a single hand.
