Please note that this "GSM" A1533 iPhone 5s model -- which is compatible with LTE bands 1, 2, 3, 4, 5, 8, 13, 17, 19, 20, and 25 (but not CDMA EV-DO) -- is intended for the North American market (AT&T and T-Mobile in the US; Bell, Rogers, Telus, and affiliate brands in Canada; and Telcel in Mexico).

Heralded as the "most forward-thinking smartphone in the world" at the time of its introduction, the iPhone 5s models, regardless of network compatibility, have a 4" (diagonal) widescreen multi-touch IPS LED-backlit 1136x640 native resolution (326 ppi) "retina display," dual cameras -- a rear 8 megapixel, 1080p "iSight" camera with 1.5 micron pixels, an f/2.2 aperture, a dual LED "True Tone" flash and more as well as a front 1.2 megapixel, 720p "FaceTime" camera.

The iPhone 5s is available in three metallic color options -- "space gray," which has a black glass front and a mostly medium toned "gunmetal" gray aluminum back; "gold," which has a white glass front and a mostly gold colored aluminum back; and "silver," which has a white glass front and a mostly silver colored aluminum back (gold color option discontinued September 9, 2015). Regardless of color, each includes a "Touch ID" fingerprint sensor embedded in the "home" button (which no longer has the traditional iPhone rounded square icon like earlier models).

This iPhone 5s model is powered by a 1.3 GHz 64-bit "Apple A7" processor and has 1 GB of LPDDR3 RAM and 16 GB, 32 GB, or 64 GB of flash storage (64 GB option discontinued September 9, 2014). It also supports both 2.4 GHz and 5 GHz 802.11n Wi-Fi, Bluetooth 4.0 and 4G/LTE, has a bottom-mounted headphone jack and uses the "Lightning" connector to hook up with a Mac, PC, dock, or power adapter.

Apple estimates that the iPhone 5s models provide "up to" 40 hours of audio playback, 10 hours of talk time on 3G, 8 hours of Internet use on 3G, 10 hours of Internet use on 4G/LTE, 10 hours of Internet use on Wi-Fi, 10 hours of video playback and 250 hours of standby time.
