This phone is supremely well built and surprisingly light considering that sturdy build quality. The screen may be small but it still competes with the best in terms of quality. There's really no need for any more pixels since at 326ppi, you can't see the individual dots anyway.
There is also no issue with performance... This is partly thanks to the fact that the A7 processor is a 64-bit chip.
The 5S has the useful TouchID sensor for unlocking the phone and making purchases with your finger
At the heart of the iPhone 5s is a powerful A7 chip that delivers slick and fast operation, even when you're multitasking.
The M7 motion coprocessor works in harmony with fitness and navigation apps, recording precise measurements such as distance travelled, speed and steps taken, without draining the phone's processor.
iSight camera and Full HD video
You'll take stunning photos every day with the iPhone 5s. The 8-megapixel iSight Camera shoots outstanding quality thanks to its five-element lens and Sapphire crystal cover, enhanced by autofocus, touch focus and face detection.
When the moment calls for more than a photo, the Full HD video with Slo-Mo and time-lapse is in hand, and the iPhone 5s also features a FaceTime camera for high-quality video chat and selfies.
Sleek design with Retina display
With its slim and light design, the iPhone 5s will be a pleasure to use. Its aluminium and glass chassis provides a premium mobile experience, and the fingerprint scanner lets you unlock your device.
The iPhone 5s boasts Apple's Retina display with breathtaking graphics, larger-than-life detail and razor-sharp text. You won't be able to take your eyes off the Retina display, with reduced glare thanks to IPS technology.
