No countdown of the best mobile phones is complete without an iPhone. The iPhone 5s is truly worthy of being called 'the greatest Apple phone since the last iPhone'. The latest iPhone has an Apple A7 chipset, and a dual-core 1.3 GHz Cyclone CPU. The phone has a 4-inch LED-backlit IPS LCD, with a resolution of 640x1136 pixels (326 ppi). The screen is protected by Corning Gorilla Glass, and has an oleophobic coating to keep fingerprints away from the screen. Talking of fingerprints, the phone has a revolutionary fingerprint reader for security, hidden beneath its Home button. The phone runs the latest version of iOS-iOS 7. It has an 8 MP primary, and 1.2 MP secondary camera. All the graphics on the phone are handled by a PowerVR G6430 GPU. The phone comes in 16/32/64 GB versions, and has 1 GB DDR3 RAM. The 5s is powered
by a 1560 mAh Li-Po battery.
