Internally, the iPhone 5S will feature a 64-bit A7 processor that will be up to twice as fast at CPU tasks. Another significant new feature is a “Touch ID” capacitive fingerprint sensor built into the home button that’s capable of scanning sub-epidermal skin layers. Touch ID can be used to unlock an iPhone and authorize iTunes purchases.
The camera in the iPhone 5S will have a new 5-element lens with a f/2.2 aperture and a sensor that’s 15% larger than the one in the current iPhone 5 and a dual-LED “True Tone” flash that will adapt to the existing lighting to provide better colors and more accurate skin tones. Other new camera features include a burst mode capable of capturing 10 pictures per second and slow-motion 720p video capture at 120 frames per second.
The iPhone 5S will cost $199, $299, and $399 for the 16 GB, 32 GB, and 64 GB models respectively with a 2-year contract. The iPhone 5S and the lower-cost iPhone 5C that was also announced today will be available in stores in the US, Australia, Canada, China, France, Germany, Japan, Singapore, and the UK starting on September 20.
