A1920 iPhone XS (A1920 Model) Specs (2021)

The iPhone XS offered several luxury upgrades over the previous generation iPhone X. Slight display enhancements, larger storage sizes, image quality improvements, and a more durable build all give the iPhone XS the edge over other iPhone models of its time. While it’s now been discontinued to give way to the new Apple flagship, the iPhone 11, you can still find iPhone XS models at authorized resellers. Here’s a look at the specs of the A1920 iPhone XS model released for the US and Canada.

The iPhone XS (A1920 model) is the most portable model of its generation.

Here’s the iPhone XS (left) placed alongside the iPhone XR (middle) and iPhone XS Max (right).

As the smallest iPhone released in 2018, the iPhone XS is also the lightest and easiest to handle. It’s targeted at professionals who are always on the go and need a mobile device they can quickly take out and tuck back in as needed. It should also appeal to those who still prefer smaller displays, though its 5.8-inch display is only small in comparison with current-gen phones. 

The Super Retina HD display of the iPhone XS is a step up over the iPhone X as well as the iPhone XR. The iPhone XS‘s OLED screen has a slightly brighter and more vibrant picture than that of the iPhone X, while the iPhone XR still sports an LCD panel. Truthfully, it’s hard to notice the difference unless you’re looking for it, and you’ll appreciate it more while watching videos rather than simply swiping through the interface or using typical apps.

Another notable difference worth pointing out, in case you’re considering the iPhone XR, is that the iPhone XS has a more durable stainless steel and glass body. It can handle drops better than the fragile iPhone X, though for phones this expensive you’d be crazy not to get a case for them. Apple also improved the water resistance of the iPhone XS, getting it an IP68 rating which means it can survive up to 2 meters underwater for 30 minutes. Again, it’s not worth simply testing it but it’s good to know you can fish it out and get it to work in case it falls in accidentally.


The iPhone XS (A1920 model) is just as fast as the iPhone XR and XS Max.

You can trust the iPhone XS to handle anything you play with it.

Since the iPhone XS, XS Max, and XR all have the same Apple A12 Bionic chip, they offer the same overall performance for apps, games, and other features. It might be a bit of a letdown considering you’re spending more over the iPhone XR, but the iPhone XS has its advantages elsewhere. It’s definitely faster than the previous generation chip on the iPhone X, but the gains are hard to notice on just daily use. Still, you can rely on the iPhone XS to run any app from the App Store without struggling.

Battery performance has marginally improved over the iPhone X, as the iPhone XS lasts roughly 30 minutes more on average. Playing videos non-stop will drain a full charge after 14 hours, but it’s less impressive when compared to the 16 hours that the iPhone XR is capable of. In fact, the iPhone XS has the smallest battery capacity among the 2018 iPhone releases but it’s largely due to it having the slimmest body. 


The iPhone XS (A1920 model) has a telephoto lens and depth control.

Smart HDR tech on the iPhone XS gives photos more vivid colors while Depth Control lets you adjust field of depth.

The dual-camera system of the iPhone XS A1920 received a substantial upgrade with Smart HDR technology. It’s essentially the combination of an improved image sensor and tweaks on the image processor that results in greater highlights and shadows, crisper image fidelity, and more accurate colors. The improvement over the iPhone X is noticeable when comparing shots taken with both phones, though it’s sometimes subtle. The telephoto lens gives it a further edge over the iPhone XR, allowing for more creative shots with its stronger zoom.

Apple also introduced Depth Control on the iPhone XS, allowing users to adjust the background blur effect in Portrait mode for more dramatic photos. This can be done after taking the photo, and both rear and front cameras have the slider. The iPhone XS also has all of the six Portrait Lighting effects you can use to create professional-level headshots. Meanwhile, the iPhone XR only has the Natural, Studio, and Contour effects but not the Stage, Stage Mono, and High-Key Mono effects.

While other smartphones like the Google Pixel 3 and Galaxy Note 9 can outclass the iPhone XS in overall image quality, there’s no doubt that it has the upper hand on video quality. Extra image stabilization and improved auto contrast via HDR give the iPhone XS the edge in producing smooth videos without the typical stutter and shake. 


The iPhone XS (A1920 model) is released for LTE, 4G, and 3G cellular networks in North America.

You can choose from Gold, Silver, and Space Gray for the iPhone XS‘s casing color.

There are four models of the iPhone XS released around the world, and they vary by their LTE, 4G, and 3G band support. The US and Canada get the A1920 iPhone XS model, while China, Hong Kong, and Macau receive the A2100 model. Japan gets its own A2098 model which allows it to work with the country’s contactless payment platform. Meanwhile, the rest of the world gets the A2097 model. It’s highly recommended that you only get the iPhone XS model intended for your country to ensure maximum Internet speeds and full wireless coverage.

Here’s the complete list of cellular bands supported by the iPhone XS A1920 model:

  • FDD‑LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 29, 30, 32, 66, 71)
  • TD‑LTE (Bands 34, 38, 39, 40, 41, 46)
  • CDMA EV-DO Rev. A (800, 1900 MHz)
  • UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
  • GSM/EDGE (850, 900, 1800, 1900 MHz)

In addition, all iPhone XS models have Gigabit-class LTE, 802.11aC Wi-Fi with MIMO, Bluetooth 5.0, and NFC. It also has GPS/GNSS for navigation and activity tracking.


The iPhone XS (A1920 model) is a slight upgrade of the iPhone XS.

All in all, the iPhone XS (A1920 model) is a step up from the previous iPhone X, with incremental upgrades on build quality, camera capabilities, and OLED display. It’s definitely made of sturdier stuff, thanks to its stainless steel body and more durable glass. However, performance-wise and price-wise, it’s much easier to recommend the iPhone XR as it’s just as fast while being much more affordable. If you want the additional telephoto lens, a better-looking display, and a slightly more portable size, the iPhone XS becomes the better option.
