How CNET tests phones

What goes into a CNET smartphone review

Phones are much more than communication devices; they’re our gateway to the internet. They’ve become the center of our daily lives, housing our personal information, work essentials, personal memories and enabling us to reflect our personalities online. That’s why CNET conducts rigorous tests to help you find the right phone for your budget and needs.

When reviewing phones, we take a variety of factors into account such as camera quality, battery life, design, software and longevity. Every phone is different, but our testing allows us to answer the same question in each review: Is this phone worth buying? We evaluate phones based on the quality of their hardware and software, whether they introduce any meaningful new innovations and whether they’re the right price.

We replace our personal phone with the test unit during the review period so that we can get an accurate impression of what it’s like to rely on the device for daily tasks. In addition to this anecdotal usage, we also conduct specific side-by-side tests against other phones as part of the evaluation process.

We generally test phones against their immediate predecessor, competing phones from other companies or another phone within the same product line (for instance, iPhone 14 versus iPhone 14 Pro). We focus on whichever comparisons are most useful for helping our readers navigate the buying decision, and that may vary depending on the phone. Whenever possible, we work all three types of comparisons into a review.

Some of these methodologies are relatively new to CNET’s testing procedures, so you may not see them in all of our reviews from 2022. We’re in the process of updating our current reviews with these tests and plan to implement them fully in 2023.

Below is a general overview of what goes into a CNET smartphone review.

Testing smartphone cameras

The camera is the biggest area where companies like Apple, Samsung, Google and OnePlus typically make improvements to new models each year, and our reviews put phone maker’s claims to the test. We take photos in a variety of circumstances and lighting conditions, including bright outdoor areas, dim indoor settings and mixed lighting.

We capture a variety of subjects (objects, pets and people) to assess boldness, sharpness, skintones and color accuracy. We test all of the phone’s main lenses (wide, telephoto and ultrawide), front-facing cameras as well as different shooting styles, like portrait mode and night mode. Our reviews also cover useful editing features or shooting modes that are specific to the device, such as the Google Pixel 7’s Face Unblur or the iPhone’s Cinematic Mode.

Part of these tests include side-by-side photo comparisons between the phone we’re reviewing and previous phones we’ve tested. We evaluate a phone’s cameras on their consistency as well as how they stack up against the competition. All photos are straight out of camera and accessed without any edits, unless specifically noted. Beyond the initial impressions we get from viewing these photos on a phone’s screen, we also upload them to a computer and view them alongside one another on a monitor. This reduces any bias that may come from the different screens on each phone. It also makes it easier to view discrepancies in clarity and color between each photo.

We also capture video with the review phone and judge it on its image and audio quality. Just because a phone can capture 6K or 8K video doesn’t mean it’s good. Unlike the computational photography algorithms that Google, Apple, Samsung and others apply to photos, videos remain relatively less processed, making it easier to critique a camera’s strengths and flaws.

Testing smartphone performance

The performance section of our reviews examines how responsive phones are in everyday use, how well they juggle multiple tasks and how they fare during benchmark tests.

We do this by observing how quickly phones can open apps and launch the camera. We also note whether the phone has an adaptive refresh rate setting and how this improves performance if at all (for example, whether this makes animations and scrolling feel smoother). We also look for signs of lag when running multiple apps (such as using a social media app or playing a game while on a video call), or playing an online multiplayer game with the highest graphics settings.

In addition to these everyday tasks, we also run a series of benchmarks designed to test a phone’s computing power and graphics performance. These tests include Geekbench 5 for general CPU performance and 3DMark Wild Life Extreme for graphics. We also run the same tests on other phones that we’re comparing our test device to.

Testing smartphone battery life

We test battery life in three ways: through an anecdotal stress test, a video streaming test and by observing battery life after everyday use. As noted earlier, these tests are relatively new and we’re still in the process of adding them to our 2022 reviews.

The anecdotal stress test measures how much the battery drains after 45 minutes of general usage. We do a little bit of everything during this test to mimic authentic everyday experiences. That includes streaming video, using social media apps, playing a game, making a video call and other miscellaneous tasks like checking email. After this 45 minutes of mixed usage, we mark down the percentage of battery drain. To keep the test consistent between phones, we perform each of those tasks for roughly 10 minutes. We also keep the screen brightness set to 50%, turn off the always-on display and keep the high refresh rate setting on (if there is one).

The streaming test monitors how much the battery drains over a three-hour period while viewing a video on YouTube. We use the same video each time for consistency and set the screen brightness to 100%. We also disable settings that automatically dim or brighten the screen, connect to Wi-Fi and turn on the adaptive or high refresh rate setting if applicable. We take battery percentages at the one-hour, two-hour and three-hour marks.

Since we use test phones as our regular devices, we also discuss how long the battery has lasted in everyday use based on our experience. Often, our practical experience with a phone’s battery life can give us the most accurate prediction of what others might expect if they bought the same phone.

Testing smartphone design, software and display

Our smartphone reviews also encompass other areas like design, software and display quality. Design can be subjective, but we generally look for factors such as durability (water and dust resistance ratings), how easy the phone is to operate with one hand, the build quality and whether the design is unique or interesting in any way. For display quality, we’ll mention factors like brightness, how easy it is to see in sunlight and sharpness and color.

Software is another key part of CNET’s smartphone reviews. We mention any new or noteworthy features and how long the phone will support new versions of Android (or iOS respectively) and security updates.

Our written review tells you everything we feel and experienced, but we also give each phone overall score and star rating to provide a different context. A $450 phone might lack all the features that a $1,000 phone has, but its value might mean it gets a higher score. We also update these ratings based on a variety of factors, including software changes and quality control issues.

Reviews will always vary depending on the device, but these are the core tenets that make up a CNET smartphone evaluation. Determining a phone’s overall value is our guiding principle in every smartphone review. Our reviews shed light on whether a new phone lives up to its expectations, who the phone is for and whether it delivers on its promises for the price. We are always evaluating our own testing methodologies and looking for ways to improve, so expect to see more updates in the future.

Galaxy Z TriFold vs. Huawei Mate XT: One Is the Most Versatile Phone I’ve Ever Used

Samsung’s Galaxy Z TriFold and Huawei’s Mate XT, part of a new category of phones called «trifolds,» offer diverging experiences when it comes to using them.

Huawei introduced the world’s first «trifold» phone, the Mate XT Ultimate, last year and launched it outside of China in February 2025. Despite only actually folding in two places, the phone was called a trifold because its 10.2-inch display divides into three sections.

I’ve been using it on and off since February and I liked the Mate XT so much that it made me skeptical about the Galaxy Z TriFold‘s design when Samsung first showcased it at the APEC CEO Summit in October. But after trying Samsung’s first trifold for myself, during a brief hands-on test at a Samsung store in Dubai, I changed my mind.

As foldable phone sales are expected to rise 30% year over year in 2026, according to analysts at IDC, it’s important for both Samsung and Huawei to find their own hook for customers. Each of these foldable phones has their place in the market and offers a different appeal. One is a tablet that folds into a phone, while the other is a three-in-one and the most versatile smartphone I’ve ever used. One of them has «Z TriFold» in its name but the other actually folds in a «Z» shape.

Here’s how the newly-launched Samsung trifold phone compares to the Huawei Mate XT Ultimate — the phone that pioneered this category.

Samsung Galaxy Z TriFold vs. Huawei Mate XT design

Both the Galaxy Z TriFold and Mate XT have large screens that divide into three panels (hence the name) and have two hinges to connect them. And yet, they’re vastly different.

The Huawei trifold phone has a single screen that folds in a Z shape to allow for three different forms. You can use it as a phone (fully folded), a mini-tablet (half-open), as well as a wide-screen tablet (fully opened). I’ve mostly used the Mate XT either in mini-tablet mode (one fold) or fully unfolded. And I found myself using it in phone mode (fully closed) only when I made calls.

In comparison, the Galaxy Z TriFold folds in a U shape as both panels fold inwards. You can only use it fully folded as a phone or fully opened as a wide-screen tablet, without the added ability to use it as a mini tablet.

Samsung’s Z Trifold uses two different-sized hinges and three panels of varying thickness, allowing the device’s flaps to fold on top of one another. The left hinge is like the one on the Fold 7 and comparatively tighter than the right hinge (the wider one), which springs open after you push it to a certain angle. On the back of the phone is a second display that occupies the «middle» section to use when the phone is fully closed.

When fully folded, its lowermost panel has a protruding edge, giving it a solid lip to grab onto while unfolding. It’s a nice addition to the flat-sided design, which doesn’t leave much space between panels. I found it easier to unfold than its sibling, the flat-sided Galaxy Z Fold 7.

The Huawei Mate XT has curved sides and a single screen, but because of that Z shape, it gives you three ways to use it. The right hinge unfolds like the Galaxy Z TriFold — you pull it out — but you don’t need to unfold the other side. With just one panel unfolded, it becomes a usable mini-tablet.

You can unfold the third section, at the back of the left panel, to open it fully and use it as a wide-screen tablet. Because it uses a single flexible screen, part of the soft folding display is always exposed to the elements when the device is folded shut in phone mode. So far, I haven’t noticed any scratches on the display but it is definitely less protected than Samsung’s inner screen. However, Huawei bundles a case with an extended lip to protect the always-exposed right side of the screen.

Both of these trifold phones have minimal screen creases but Samsung’s Galaxy Z TriFold feels better when I run my finger over the folding parts. While Huawei’s creases are deeper, they don’t bother me in day-to-day use. The creases on both phones are visible under direct artificial light and at an extreme angle.

The Huawei Mate XT is slimmer than the Galaxy Z TriFold. It’s just 3.6mm thick at its thinnest part when fully unfolded and 12.8mm when folded. In comparison, the Samsung phone is 3.9mm thick at its thinnest part and goes up to 12.9mm when fully unfolded. At 309 grams, the Z TriFold is also slightly heavier than the 298g Mate XT.

The Huawei trifold phone feels more premium than the Galaxy Z TriFold — probably because of its faux leather back, curved sides and gold accents. Samsung’s foldable has a carbon-fiber finish, which feels durable but not as premium.

The Mate XT has an IPX8 rating, while the Galaxy Z TriFold is rated IP48 for dust and water resistance. The «4» in IP48 means it’s protected against dust particles measuring over 1mm but not against everyday dust and pocket lint. Neither of these phones is truly dust-proof, but both are rated for water resistance, just like a standard smartphone.

Samsung Galaxy Z TriFold vs. Huawei Mate XT displays

The Galaxy Z TriFold has two screens: a Galaxy Z Fold 7-like 6.5-inch AMOLED screen with a 120Hz variable refresh rate and a 422ppi pixel density. It unfolds to a 10-inch tablet-sized screen with a 120Hz dynamic refresh rate with a lower 269ppi pixel density.

The Huawei Mate XT has a single 10.2-inch OLED screen with a 90Hz refresh rate and 382ppi pixel density. It has a lower refresh rate but a higher resolution and slimmer bezels. You can use it as a 6.4-inch phone, a 7.9-inch mini-tablet or a 10.2-inch widescreen tablet which makes it a more versatile design than Samsung’s trifold phone. The Mate XT’s display when folded down into «cover screen» has a wider aspect ratio with slimmer bezels than the TriFold’s cover display.

I haven’t watched videos on the Galaxy Z TriFold, but I assume the experience would be better on the Huawei since the main screen has a wider aspect ratio (when fully unfolded). It has less letterboxing (thick borders on top and bottom) than the Galaxy Z TriFold, which provides a slightly narrower aspect ratio when fully unfolded. However, it could be better for multitasking, especially when running three apps side by side, but I’ll need more time with the Samsung phone to come to a conclusion.

Galaxy Z TriFold vs. Huawei Mate XT performance and battery

The Samsung Galaxy Z TriFold has the Qualcomm Snapdragon 8 Elite for Galaxy chip, the same processor that powers its other 2025 flagship smartphones including the OnePlus 15. The chip is tuned for efficiency and I expect it to handle multitasking on a standalone DeX with ease. The TriFold also comes with 16GB of RAM and 512GB or 1TB of storage.

In contrast, the Huawei Mate XT runs on an in-house Kirin 9010 chip and is paired with 16GB of RAM and 512GB or 1TB of storage. It runs EMUI 14.2 operating system on global variants, which doesn’t have preinstalled Google apps. Despite the ban on US companies working with Huawei — including Google, the company behind Android — there are workarounds for installing the Play Store. You won’t encounter these kinds of hurdles on the Galaxy Z Trifold.

The Samsung trifold phone runs on One UI 8, based on Android 16. You get fast animations, smooth multitasking, a multitude of customization options and a better overall experience. The Galaxy Z TriFold will also get seven years of OS and security updates.

Both phones pack a 5,600-mAh battery but it remains to be seen how they fare against each other. I haven’t pushed the Mate XT to its limits and it delivers an entire day of use on a single charge. When I need to top up the battery, I use the bundled 66-watt charger or use wireless charging at up to 55 watts. The Galaxy Z TriFold supports 45-watt fast charging and Qi wireless charging.

Samsung Galaxy Z TriFold vs. Huawei Mate XT cameras

Both phones have three rear cameras that are identical to those found in the Galaxy Z Fold 7. The Galaxy Z TriFold has:

a 200-megapixel main camera with optical image stabilization (OIS) and a f/1.7 aperture
a 12-megapixel ultrawide camera with a 120-degree field of view
a 10-megapixel 3x optical zoom telephoto camera with OIS and support for 30x digital zoom
two 10-megapixel front-facing cameras — one inside the cover display and the other inside the folding screen

In comparison, the Huawei Mate XT has:

a 50-megapixel main camera with OIS and a variable aperture (f/1.4 — f/4.0)
a 12-megapixel 5.5x optical zoom telephoto camera with OIS
a 12-megapixel ultrawide camera with a 120-degree field of view
a 8-megapixel selfie shooter

Based on my experience with the Fold 7, you can expect vibrant colors, good dynamic range and balanced processing in low-light photos on the Samsung trifold phone. Images from the Huawei tend to have an over-processed look and it doesn’t do well with certain skin tones. But the Mate XT captures better portraits than my Fold 7. I’ll be able to test the photography chops from both phones once I have the Galaxy Z TriFold.

Here’s how the two foldable phones specs compare:
