Review: Sony Xperia XZ1

Hardware Software Wrap-Up Comments

The Sony Xperia XZ1 is one of the first smartphones to run Android 8 Oreo. It packs the latest processor and camera technology into Sony's age-old, metal-and-glass chassis. While some table-stakes features are aboard, others are missing. This uneven effort from Sony has a lot going for it, but there's plenty holding it back. Here is Phone Scoop's full review.

Is It Your Type?

The Xperia XZ1 is a high-end handset from Sony that crams top specs into a metal and glass chassis. Media features are its strengths, but there are some surprising gifts under its aluminum hood. Read on to find out what they are.


Much like Apple, Sony hasn't updated its smartphones' basic design language in half a decade. The XZ1 looks incredibly similar to the XZ, which looked incredibly similar to its predecessor and so on and so forth.

The design language used here is something Sony calls "Loop". The metal side edges are neatly curved and create a seamless "loop" when you view the phone's ends. The device still has the distinct corners that Sony's handsets are known for, which may make the phone uncomfortable in your pocket. The improvements in the design are small, but they do make for a more attractive and usable device.

Perhaps the best thing about the XZ1 is that it upgrades to an all-metal chassis. The entire rear panel is a seamless piece of material that wraps around the sides, creating a completely smooth contour. The 2.5D glass front panel fits into the frame nicely. The metal and glass combo is really appealing.

The phone's size is manageable. It has a smaller 5.2-inch screen, though the ridiculous bezels add a lot to the phone's footprint. Even so, it stands well under 6 inches tall and sits well under 3 inches wide. Almost everyone should be able to use the phone one-handed. The XZ1 is slim at 7.4mm, and slips into pockets just fine. The phone is roughly the same size as Samsung's Galaxy S8 and the LG G6, but with a smaller screen.

Sony has never skimped on quality, and the XZ1 is no exception. The glass front panel is exceptionally smooth under the thumb. The rounded metal chassis is perfectly shaped and mated to the glass and end caps seamlessly. The metal build of this year's phone is a huge improvement over the polycarbonate of the XZ. This is a flagship phone through and through, and Sony assembled it tightly.


The front face is all glass. As noted, Sony is one of the worst offenders when it comes to ugly bezels. There's nearly an inch of framing above and below the screen, with several millimeters on either side of the screen as well. The display is swimming in a too-big frame. It's a design from yesteryear that's beyond dated and needs to change. The XZ1 has stereo speakers.

A hatch on the left edge covers the SIM/memory card tray. It's no trouble to find and use. I particularly like that you can pull it out without a tool; a fingernail will do. The rest of the controls are piled up on the right edge. The lock button is near the middle of the side edge. It's rather flat, but easy enough to find. The volume toggle is positioned above the screen lock key and works well. It has a slim profile and I like the travel and feedback. The dedicated camera button is where you expect to find such a key, at the bottom of the right edge. It's a two-stage control and functions perfectly.

The headphone jack is on top and the USB-C port is on the bottom.

There is no fingerprint reader in the U.S. version, a huge omission for a flagship phone.

The rear metal panel is perfectly flat. I like the quality of the paint and metal finish. The camera elements are tucked into the top-left corner. The round module sticks out about 1mm. It's much smaller than the camera bump on the iPhone 8/Plus. The phone has a laser to assist in focusing on your subject. The focus/flash array is positioned to the right of the camera module in a thin strip. The painted-on Xperia logo is hardly visible on the metal. The rear panel is a solid piece and cannot be removed, nor can the battery. It's incredibly plain, but I'd call that a bonus.

Like many Xperia handsets, the XZ1 is rated IP68 for protection against water and dust. It can sit in 1.5 meters of water for up to 30 minutes with no worries. That's a table-stakes feature for today's flagship smartphones and Sony nails it. I tested the XZ1 in the shower, in a bucket, in the local river, and other wet environs. It survived like a champ.

I'm utterly bored with Sony's design language at this point, but the company does continue to manufacture quality hardware that functions as it should.


The 5.2-inch 1080p HD display is fine for what it is. The screen is bright, colorful, and clear. I think Sony is missing the boat with respect to the resolution, however, and it's past time Sony up its game. Most competing flagships have quad HD screens, which is much better for virtual reality. Sony told us it is skipping quad HD screens and will eventually go straight to ultra HD (4K) once they make more economic sense. We've already seen at least two 4K handsets from Sony, such as the XZ Premium released earlier this year. Those screens were incredibly impressive, though rather pricey. Many competing phones also have a screen with a 2:1 aspect ratio that fills more of the phone's face. For now, however, Sony is sticking with full HD resolution and the 16:9 aspect ratio.

The pixel density on the XZ1 is certainly good, thanks to the small size of the screen. Sony's slogan-y display tech (Bravia Engine, TriLuminos, et al.) doesn't appear to add much obvious real-world value. Viewing angles are good, and outdoor visibility is fine as long as you crank up the brightness.

Sony's software gives you a lot of control over how the screen behaves. For example, you can select from three different color profiles (adjusts saturation), as well as white balance. The display supports use with gloves, though you have to manually enable this setting.



Sony is selling the XZ1 unlocked in the U.S. with support for AT&T/T-Mobile. It includes band 66 for T-Mobile, though not band 71. (At the moment, band 71 is only a big deal if you live in the sticks.)

I tested the phone on both AT&T and T-Mobile in the NYC area and came away impressed. The phone handily latched onto AT&T and T-Mobile's 4G LTE networks and remained there throughout testing. Data speeds were robust, but didn't reach the peaks I've seen from other flagships. In real world terms, the XZ1 was able to stream video via YouTube and music via Spotify with no trouble. I saw little to no buffering and didn't experience any dropouts or pauses. Social networks like Facebook, Twitter, and Instagram all loaded content swiftly. It's a good data phone.

As for making phone calls, the handset was able to connect on the first dial each time I made a call. The phone maintained calls over miles of highway driving perfectly.


I'd rate call quality as very good, but short of superb. The earpiece produces clean calls that are free of distortion and noise. Voices sound nice and crisp. People I spoke to through the XZ1 said I sounded excellent.

I wish volume were just a bit better. I had to keep the volume set to the max in order to hear calls at home, in the car, in coffee shops, and so on.

The speakerphone is more prone to distortion when cranked up, but holy hellfire can this phone get loud. Sony updated the amplifiers for its speakers, and sure enough, this phone pushes a lot of air. I had no trouble hearing speakerphone calls in noisy spaces. It's crazy loud.

Ringers and alerts are jarringly noisy. The vibrating alert is amazing.


The XZ1 has a 2,700 mAh battery tucked inside, which is definitely short of impressive. In fact, it's 10%-30% smaller than those of competing flagships. But worry not. After several days of testing, it's clear that the battery is well-matched to the rest of the hardware. The result is a phone that I could barely kill during a day of rigorous testing. Most people should be pleased with the battery life they get from the XZ1. The majority of the time I used the phone it managed to make it from breakfast to bedtime, though with only a few percent to spare. If you tweak the settings a bit you might have more of a cushion at the end of the day.

The handset includes the base Android power-management tool. It can help a bit if you suddenly find yourself at 10%. The XZ1 also includes Sony's advanced battery tools, including extended modes. Activating the base Sony power-save mode automatically delivers hours of extra battery life by dimming the screen, adjusting radios, quieting notifications, and similar. If you bother with extreme mode, you'll easily score a half-day more from the battery because it shuts down all the but core apps.

More importantly, the XZ1 supports rapid charging technology for quick powerups. Sony claims plugging your phone into the included charger for just 30 minutes will give you an entire day's worth of battery life. I don't know about that, but the phone does charge crazy fast.

Due to the metal rear panel, the XZ1 does not support wireless charging.


Bluetooth, GPS, NFC, WiFi

The XZ1 has a good selection of secondary radios and they all perform really well.

You'll find Bluetooth 5.0 aboard. When it came to connecting to headsets, speakers, cars, and other devices, the XZ1 got the job done. The phone paired with little effort. Phone calls passed through my car's hands-free system were adequate. Music, on the other hand, sounded amazing when streamed to my favorite headphones. The phone supports aptX HD, which is the newest high-resolution stereo Bluetooth codec. As long as you have a compatible piece of audio gear, expect to be impressed.

The GPS radio interacted well with Google Maps. The XZ1 was able to pinpoint my location within just a few seconds of opening the app, and accuracy was as good as about 20 feet. The phone managed real-time navigation with no trouble at all.

The NFC radio that's aboard the XZ1 helps it pair with Bluetooth accessories and also supports Android Pay.

The WiFi worked very well.
