<P> The iPhone 5S maintains a similar design to the iPhone 5 , with a 4 in ( 10 cm ) LCD multi-touch Retina display and a screen resolution of 640 × 1136 at 326 ppi . Its home button has been updated with a new flat design using a laser - cut sapphire cover surrounded by a metallic ring ; the button is no longer concave , nor does it contain the familiar squircle icon seen on previous models . The phone itself is 0.30 in ( 7.6 mm ) thick and weighs 112 grams ( 4.0 oz ) . The phone uses an aluminum composite frame . The device is available in three color finishes ; `` space - gray '' ( replacing black with slate trim on the iPhone 5 ) , white with silver trim , and white with gold trim . The iPhone 5S was the first iPhone to be available in gold color ; this decision was influenced by the fact that gold is seen as a popular sign of a luxury product among Chinese customers . </P>
