CUPERTINO, Calif. (AP) — Apart from new colors, the exterior of Apple's new iPhones doesn't look much different from last year's model. The iPhone 5S is identical to the iPhone 5 in size and weight, while the iPhone 5C is only slightly bigger and heavier. The 5C also uses plastic instead of aluminum and glass.
Where the phones differ most is on the inside. The 5S has a faster chip, a fingerprint sensor and a better camera, and both new models are compatible with a greater range of 4G LTE frequency bands. Both phones also come with the new iOS 7 operating system, a major departure in style and functionality from the iOS 6 that came installed on the iPhone 5.
Here's a closer look at how features in the three phones compare:
— Only the iPhone 5S has a fingerprint sensor. The home button of the 5S recognizes your prints and can use that instead of a four-digit passcode to unlock the phone.
— The main camera on the 5S is better at picking up light, which is useful for night and indoor shots. Although all three phones have 8-megapixel cameras, individual pixels on the 5S are larger, and the camera's shutter can open wider. Combined, Apple says that translates to a 33 percent improvement in light sensitivity.
— The flash on the 5S is better, too. Unlike other cameras, iPhones or otherwise, the flash on the 5S shoots two different lights at once — one whitish and the other amber. The iPhone adjusts the combination automatically to account for ambient lighting conditions. That results in better skin tones and more natural colors, as the normal flash sometimes overpowers whatever light is naturally there.
— The front-facing camera on both the 5C and the 5S are better. Although the cameras remain at 1.2 megapixels, the pixel sizes on both are larger.
— The 5S can shoot slow-motion video and take up to 10 photos per second. The 5 and the 5C can't do slow motion. The 5C does allow for continuous shooting, but only at about 2.5 shots per second.
— The A7 processor used in the 5S is faster than the A6 found in the 5 and the 5C. Apps and Web pages typically open a blink of an eye faster. The 5S boots about five seconds faster than the 5C.
