Apple Inc. said Tuesday it is replacing the iPhone 5 with two different phones — the higher-end iPhone 5S, which can be bought with a gold case, and the more affordable “unapologetically plastic” iPhone 5C.

The iPhone 5S features a new system-on-a-chip that Apple claims will make it twice as fast as its predecessor and it is the first-ever 64-bit smartphone. It also features Touch ID, a fingerprint authentication security feature.

The iPhone 5S case will be made of high-grade aluminum and is being made available in three metallic colors — silver, gold and “space gray.”

The phone is billed to have battery life that is as good or better than the iPhone 5: 10 hours of 3G talk time, 10 hours of LTE browsing, 10 hours of Wi-Fi browsing, up to 250 hours of standby.

On the other end of the product spectrum, the iPhone 5C is slated to come in at least five colors with green, blue, white, red and yellow being shwoed to the public.

The iPhone 5C will be sold at USD99, making it the cheapest iPhone ever sold by Apple.
