The iPhone 5S is the successor to the iPhone 5 with most of the significant changes having taken place inside the device. The camera on this device is also better than its predecessors. The 8 megapixel camera with dual LED flash takes really sharp photos even in a low-light environment. The device's screen is also sharper than the iPhone 5, making it ideal for FaceTime and watching videos. Thanks to the improved battery, this device offers stand-by time of 250 hours, meaning you don't have to charge it as often. The 5S also has a Touch ID fingerprint scanner which allows you to easily unlock your phone with your finger. Do you like the iPhone 5S but gold is not your colour?
