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.

Nintendo Switch 2: Every Reveal About the Console, New Games, Price, Release Date

The $450 console launches June 5, with Mario Kart World the highlight of its launch day game lineup.

The Nintendo Switch 2 console’s biggest reveal yet arrived Wednesday as part of the company’s latest Nintendo Direct event. This teed up a day of Switch 2 reveals that include its June 5 release date, a $450 price, its specs and its initial game lineup that extends from launch into 2026.

The console will be further buoyed by having Mario Kart World as a launch title, which will go on sale in either a $500 bundle with the Switch 2 or on its own for $80 — making the open-world racing game one of Nintendo’s most expensive yet. Other games announced, such as Donkey Kong Bananza, are being priced around $70, which matches the cost of 2023’s The Legend of Zelda: Tears of the Kingdom. That Zelda game and Breath of the Wild are among the original Switch titles that will get enhanced Nintendo Switch 2 Edition upgrades, a premium upgrade allowing players to get new features, modes and graphical enhancements that take advantage of the newer system’s capabilities.

Here are the top highlights from Nintendo’s console event, all of the games we’ve heard about so far (including new titles, Nintendo Switch 2 Editions and GameCube games coming to Nintendo Switch Online) and all of our coverage so far. You can also check out our Nintendo Switch 2 live blog for even more updates about the Switch 2 as we learn them.

Nintendo Switch 2 console

The Nintendo Switch 2’s specs saw a noticeable technical bump over the Switch. The Nintendo Switch 2 has a 7.9-inch, 1080p resolution LCD that supports a 120Hz refresh rate — matching what we now see on most Android phones. When the Switch 2 is docked, compatible games can run in 4K resolution. The new dock also includes a cooling fan.

The Switch 2 comes with 256GB of internal storage, and the new Switch 2 Game Cards will load games faster. For digital libraries, however, the Switch 2 will only work with microSD Express cards, which are different from the microSD cards that are compatible with the prior Nintendo Switch. Nintendo will have a Software Transfer feature available to help move games and data from the original Switch to the Switch 2.

The new Joy-Con for the controllers will support mouse controls, and a new C button will be part of a new GameChat communication feature that allows both voice and video chat. There’s also a Nintendo Switch 2 Camera, allowing players to see each other.

The Switch 2 also adds a second USB-C port to the top of the system, which Nintendo says can help connect its new camera accessory or charge the console when playing in tabletop mode. Nintendo also revealed a new Switch 2 Pro Controller with the C button and customizable GL and GR buttons on the back.

Following the presentation, Nintendo unveiled the system’s price of $450 in the US. It will also sell the Switch 2 bundled with a digital version of Mario Kart World for $500.

Mario Kart World

Mario Kart World removes its traditional boundaries and lets drivers roam freely across an entire world of race courses. The game will get its own Nintendo Direct later this month, where we’ll see additional details, but we already know it’ll include traditional races and a Free Roam mode, much like in the Forza Horizon series.

Getting the game bundled for an extra $50 on the cost of the Switch 2 might be the move if you are interested in the game, because Nintendo announced on its website that standalone copies of Mario Kart World will cost $80.

Joy-Con 2 C button and GameChat

Nintendo’s rolling out its new C button across several new Switch 2 controllers. The button will be used for the new GameChat communication features without a headset. The button will be used alongside a microphone on the console itself, which Nintendo says can be used whether it’s docked to a TV or in handheld mode.

In its teaser video, Nintendo promises the microphone will be able to cancel out loud background noises. GameChat will also work with a Nintendo Switch 2 Camera, allowing video chat and various camera-based game modes in supported titles. GameChat will be free at launch through March 31, 2026.

Nintendo Switch 2 Edition games upgrade titles

The Nintendo Switch 2 will play three types of games: original Switch games, Switch 2 games and Switch 2 Edition games that will receive substantial enhancements. For many of these Switch 2 Edition games, you’ll need to buy an upgrade pack if you own the original for Switch. Many of them will get more than just enhanced graphics in the upgrade; for example, Super Mario Party Jamboree will get new games that support the new Joy-Cons’ mouse controls, audio recognition and video camera gameplay options through the Switch 2 Camera.

Other Nintendo Switch games that are getting Switch 2 Edition options include The Legend of Zelda Breath of the Wild, The Legend of Zelda Tears of the Kingdom, Kirby and the Forgotten Land, Metroid Prime 4 Beyond and Pokemon Legends: Z-A. Enhancements vary: The Zelda games will start working with a companion phone app for maps and sending schematics to friends, while Kirby will get a new story that’s exclusive to the Switch 2 Edition. On the third-party side, Civilization 7 will get mouse controls.

Nintendo did not announce what upgrade packs will cost. However, some Switch games will get free updates that will improve performance or enhance features when playing them on the Switch 2. The Switch games getting these updates include:

Hyrule Warriors: Age of Imprisonment

Hyrule Warriors: Age of Imprisonment is a new game set in the world of Zelda that tells the story that leads into The Legend of Zelda: Tears of the Kingdom. This appears to be similar to how Hyrule Warriors: Age of Calamity told the story of a war that led to the events of Breath of the Wild. The teaser shows Zelda discovering that she’s arrived in the past of Hyrule, and the game will expand on how she gets involved in the corresponding Imprisonment War.

Nintendo Switch 2 games

Several other first- and third-party games were spotlighted during the Switch 2 Direct. These include Donkey Bananza, one of the first 3D platforming games featuring DK since 1999’s Donkey Kong 64. Kirby will also return to the racing genre in Kirby Air Riders, which comes more than 20 years after the GameCube racer Kirby’s Air Ride. DragXDrive will use mouse controls to control a futuristic wheelchair basketball game in which players will simulate push and pull motions to control their character.

An onslaught of Switch 2 third-party games were quickly shuffled through during the Direct, which I list below. An unnamed James Bond game is in development at Hitman studio IO Interactive, as is a darker title from Elden Ring creator FromSoftware called The Duskbloods, which will be exclusive to the Switch 2.
