iPhone 5 is just 7.6 millimetres thin. To make that happen, Apple engineers had to think small, component by component. They created a nano-SIM card, which is 44 per cent smaller than a micro-SIM. The intelligent, reversible Lightning connector is 80 per cent smaller than the 30-pin connector. The 8MP iSight camera has even more features ó like panorama and dynamic low-light mode ó yet itís 20 per cent smaller. And the new A6 chip is up to 2x faster than the A5 chip but 22 per cent smaller. Even with so much inside, iPhone 5 is 20 per cent lighter and 18 per cent thinner than iPhone 4S.
