The black refurbished iPhone 5S with 16GB storage capacity is quick and lovely to look at. The design of the device is largely the same as the iPhone 5 but the internal workings have been overhauled. The iPhone 5S is the first model with Touch ID and is one of the most popular refurbished smartphones. With the 8 megapixel camera with dual LED flash, you can even take photos in low light conditions. The A7 processor makes the device really quick and the 4 inch screen ensures a sharp image when looking at photos or films. The iPhone 5S has an improved battery, giving you stand-by time of 250 hours. Want this device but in another colour or with more storage? Check out all the versions of the iPhone 5S.
