However, it's 2017 and this phone has not been sold by Apple for over a year now, and has been superseded by the iPhone SE, a smartphone with significantly better specifications and the exact same design.
This was the second iPhone to ship with Lightning, a proprietary port Apple created as a successor to the 30-pin connector that had been used since the early iPod generations. This phone still had the 3.5mm auxiliary jack that the iPhone 7 onwards lacks.
The iPhone 5S still runs the most up-to-date version of iOS, iOS 10, however it is unlikely it will run iOS 12. Because it was the first 64-bit iPhone, it will most likely have the longest longevity from any phone released in the last 5 years, as the architecture is supported going into the 32-bit free iOS revisions come iOS 11. The phone is a piece of history, as it was the landmark phone transitioning between 32-bit mobile operating systems and 64-bit recent models. In a matter of 4 years every device Apple sells is now 64-bit.
This iPhone will always be an important piece of technology history, not just for Apple fans, as it had a giant effect on the phone market. Touch ID, 64-bit processing, and a build carried over from the iPhone 5 that is regarded as one of the best phone designs to this day.
