Forward thinking. With iPhone 5s, Apple designers and engineers found ways to add even more features while preserving the thin, light design. These features aren't just what's technologically possible, but what's technologically useful. Touch ID. A new fingerprint identity sensor. Put your finger on the Home button, and just like that your iPhone unlocks. Your fingerprint can also approve purchases from iTunes or the App Store. All-new A7 and M7 chips. The new 64-bit A7 chip delivers up to 2x faster CPU and graphics performance. And the new M7 motion coprocessor handles specific tasks to make iPhone 5s even more power efficient.
