The iPhone 5s is purposefully imagined featuring a 4-inch Retina display an A7 chip with 64-bit desktop-class architecture the Touch ID fingerprint sensor an 8MP iSight camera a FaceTime HD camera LTE and Wi-Fi 1 iOS and iCloud. It s loaded with features and innovations meticulously considered and precision crafted. The iPhone 5s was also the first to support Touch ID.
