All fingerprint information is encrypted and stored securely in the Secure Enclave inside the A7 chip on the iPhone 5s; it's never stored on Apple servers or backed up to iCloud
The iPhone 5s is powered by the new 64-bit A7 chip, which provides processing and graphics performance twice as fast as the A6, according to Apple. The upcoming iOS 7 comes with native 64-bit kernel, libraries, and drivers, with Xcode support and backwards compatibility.
The iPhone 5s also includes the new M7 motion coprocessor that gathers data from the accelerometer, gyroscope and compass to offload work from the A7 for improved power efficiency. The new CoreMotion APIs will let developers exploit the advantages of the M7.
The iPhone 5s has a new 8 megapixel iSight camera with a 15 percent larger active sensor area (f/2.2 aperture). These improvements, along with the Apple-designed image signal processor in the A7 chip and the new Camera app in iOS 7, provide up to two-times faster auto-focus, faster photo capture, automatic image and video stabilization, and better dynamic range.
The new True Tone flash variably adjusts color and intensity for over 1,000 combinations, so photos taken with a flash appear more natural. iPhone 5s also includes a new Burst Mode, Slo-Mo video with 120 fps, a new FaceTime HD camera for better low-light performance and audio-only FaceTime calls with iOS 7.
As for the battery life, Apple estimates 250 hours standby on a charge, or 10 hours 3G talk time, 10 hours LTE browsing time or 40 hours of music playback.
Now for the most important information of all, how much an iPhone 5S costs and when it will be available. With a two year contact, the iPhone 5S is available with 16GB storage for $199, 32GB of storage for $299 and 64GB of storage for $399. It will be available from September 20 from stores.
