I am still a fan of iPhone 5s, over newer 6 or 6s. It’s much cheaper then iphone 6 and 6s, but with all the same features including fingerprint authentication and a powerful 64-Bit processor. If a bigger screen is not your priority then this is a good cheaper iPhone.
The box came with 2.1 Ampere Charger, which comes with iPhone 6s and iPad. Previously iPhones use to ship with 1-Ampere charger, and I believe apple is now putting same 2.1 Ampere Charger with old generation iPhone too. This is a GOOD THING, it charges twice as fast.
