The refurbished iPhone 6S 16GB was brought out by Apple in 2015. The design of the device is largely the same as the iPhone 6 but the internal workings have been completely overhauled. The 6S has a powerful A9 processor and is therefore much quicker than the iPhone 6 and the battery lasts longer. A capacity of 2750 mAh gives this iPhone 6S a stand-by time of up to 384 hours. The camera in the iPhone 6S has been improved too. With a 12 megapixel camera at the back and a 5 megapixel camera at the front, you can take really sharp photos. The refurbished iPhone 6S 16GB from refurbished.store comes with a 3 year warranty. Looking for an iPhone 6 but with greater storage capacity?
