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.

Tariff Impacts Are Real: These 13 Companies Have Confirmed Price Hikes

More and more companies are confirming price hikes as President Trump’s tariffs are poised to take effect — most recently, a popular smart lighting brand.

In many cases and for many products in the US, the biggest impacts of President Donald Trump’s aggressive tariff plans haven’t hit yet — but they could soon, unless the 90-day pause on some rates is extended. Still, numerous companies have already hiked prices or said that they’ll increase in the near-future — including, most recently, a popular and CNET-approved brand of smart lights.

The fact of the matter is that tariffs — a tax placed on the importing of certain products into a country — will ultimately cause prices to go up, with Walmart characterizing these eventual price hikes as «inevitable» during its earnings call last month. Given Trump’s push to place historically high tariffs on goods from almost every country in the world, you can also expect these price hikes to hit a huge variety of products.

This truth has begun to sink in for a lot of Americans. About 38% of consumers feel pressured to make certain purchases before tariffs cause their price to go up, according to a recent survey conducted by CNET. About 10% of respondents said they’d already made certain purchases in hopes of avoiding future price hikes, while 27% said they’d delayed purchases of products costing more than $500. Overall, these concerns about prices were felt the most around popular tech pieces such as smartphones, laptops and home appliances.

To help you keep score, I’ve put together a list of all the companies that have either confirmed or warned of price hikes due to Trump’s tariffs. As other companies make such announcements, you can expect new names to be added here.

Continue on for all those details, and for more, find out why it’s best if you wait on buying a new iPhone.

One item you won’t find on this list yet? The original Nintendo Switch, which will see a currently unspecified price hike on Aug. 1, but only in Canada for the time being. If that increase makes its way south of the border, we’ll let you know.

Best Buy

Without getting into specifics, Best Buy CEO Corie Barry told the Wall Street Journal late last month that it has already raised prices on certain products as part of its response to the tariffs.

e.l.f.

Known as an affordable option in the beauty world, e.l.f. announced in late May that it would be implementing a $1 price hike across its product line in response to the tariffs. CEO Tarang Amin claimed that the reaction from customers was positive, on account of the company’s transparency.

«We’re not trying to pull anything over on anyone,» Amin told Fortune. «This is exactly what we’re facing, and they understand.»

Macy’s

Speaking to CNBC in late May, Macy’s CEO Tony Spring said that price hikes will be implemented on some products due to tariffs, while also emphasizing that other tactics — like discontinuing certain products altogether — will also be a response to rising costs.

Mattel

Known for brands like Barbie and Hot Wheels, Mattel sounded the alarm over likely price increases during an early May earnings call. While it’s unclear how much the toymaker’s prices have increased since then, the company told investors that it would be, «where necessary, taking pricing action in its US business,» or to put it plainly, raising prices for consumers to mitigate the impact of tariffs.

Nikon

Camera-maker Nikon will introduce price hikes in response to Trump’s tariffs, effective June 23. This move will only target lenses and accessories the company makes and sells, so the cameras themselves are safe for now.

«We will be carefully monitoring any tariff developments and may adjust pricing as necessary to reflect the evolving market conditions,» a statement from Nikon explained. «We wish to thank our customers for their understanding and know that we are taking every possible step to minimize the impact on our community.»

Philips Hue

Parent company Signify announced that prices for its popular and highly regarded Philips Hue brand of smart lights will see price hikes effective July 1. The company also confirmed that this decision was made «as a direct result of tariffs.»

«Signify reserves the right to modify prices based on new or additional tariffs becoming effective in the future,» the company’s official statement explained.

Ralph Lauren

Sales at the luxury goods retailer Ralph Lauren have apparently remained steady amid recent uncertainty, but the company is still forging ahead with a plan to combat tariff impacts by raising prices more than it had already intended to, according to the Wall Street Journal.

Shein and Temu

Trump’s tariffs have made a notable target of China, hitting the country with a 30% rate only after initially hiking it all the way to 145%. Online retailers like Shein and Temu rely on direct shipments from markets like China in order to offer the rock-bottom prices that made them famous, so it’s little surprise now that they’ve had to raise prices.

The Trump administration has furthered the issues faced by these companies by doing away with a rule known as the «de minimus» exception, which used to exclude smaller purchases under $800 from import taxes. With that rule gone, Trump’s China tariffs will now apply to both bulk orders of industrial building materials and those shoes you’ve been looking to buy from Shein.

Subaru

Subaru has hiked prices across almost its entire line. The increase ranged from $750 to $2,055, depending on the model, with only the EV Solterra avoiding any change.

As has become a trend with some companies, Subaru avoided attributing the price hikes to Trump’s tariffs, citing only the common refrain of «market conditions.» Trump has notably disparaged companies that explicitly lay the blame for price hikes on his policies.

«The changes were made to offset increased costs while maintaining a solid value proposition for the customer. Subaru pricing is not based on the country of origin of its products,» a Subaru spokesperson said in a statement to Car & Driver.

Stanley Black & Decker

In an earnings report published April 30, toolmaker Stanley Black & Decker addressed «Price Actions in Response to US Tariffs,» stating that it had «implemented an initial price increase in April and notified our customers that further price action is required,» and was also looking into ways to shift its supply lines to minimize the impact of tariffs.

Volvo

The price impact of tariffs at Swedish automaker Volvo are confined, for now, to just one model: the electric EX30. Initially it was set to start at $34,950 in the US — a competitive price for an EV — but tariffs targeted at imported cars forced the company to raise the price to $46,195, a 32% bump.

Walmart

The biggest grocery chain in the US, Walmart is perhaps the most prominent company yet to announce imminent price hikes due to Trump’s tariffs. During the company’s earnings call in May, CEO Doug McMillan said price hikes would begin by the end of May and impact things like food, electronics and toys.

This Unique Controller Is Cool but Pointless for Most Gamers

The Turtle Beach Stealth Pivot has a unique 2-in-1 feature, but most people will never use it.

Pro-level game controllers have been becoming more mainstream over the past several years, offering gamers a host of new features not found on the controllers that came with their systems. These features include extra mappable buttons, swappable gamepads and other customizability options.

However, I don’t think I’ve ever seen a controller that offers two dedicated button layouts within the same device. The Stealth Pivot from Turtle Beach lets you physically rotate the gamepads to reveal a whole new, previously hidden, button layout — all without having to remove anything. It’s a unique take on what a controller can be and I’m here for it.

What I like about the Stealth Pivot

I’ve been impressed with Turtle Beach controllers for a while now, and the Stealth Pivot continues continues the company’s streak of great hardware. The buttons are clicky and responsive and the whole thing feels wonderful to hold. The design is nearly identical to Microsoft’s own Xbox controllers, which is a good thing.

The Stealth Pivot keeps many of the same pro features as its Stealth Ultra controller (and many other pro-level controllers), including adjustable triggers and four additional, remappable buttons. The Connected Command Display is carried over as well, although it’s much smaller than the Ultra’s 1.5″ screen. Amazingly, it keeps all the same features , including being able to adjust buttons and social media notifications.

On the connectivity side, you’ve got a wired connection for Xbox (there’s no wireless support), a 2.4GHz dongle for PC and Bluetooth for mobile devices and compatible smart TVs. There’s a headphone jack at the bottom and the USB-C port for charging or Xbox connection is up top. You can play and charge at the same time, which is a nice bonus.

Two controllers for the price of one

The biggest feature of the Stealth Pivot by far is its rotating gamepads. Basically, you twist down the two joysticks, unlock the gamepads, then literally rotate them 180 degrees to reveal the other set. This second set has a layout typical of controllers designed for fighting games, or really, any game where additional buttons are valuable. So instead of joysticks, there’s a D-Pad on the top left flanked by two two buttons. On the right side, the ABXY cluster shifts downward to make room for two additional, mappable buttons.

So now, instead of having to buy multiple controllers or remove and swap out gamepads (like PDP Victrix Pro controllers), in just a few seconds you can switch from snapping headshots in Call of Duty to beating up bad guys in Mortal Kombat or Tekken. It’s certainly not something I’ve ever seen on any other controller and it works surprisingly well. You can even save up to five digital profiles on the controller so you can have different layouts for each game.

I was impressed by just how good the buttons and everything are on the Stealth Pivot, even with having to cram double the amount of most everything into the same space. Granted, the controller is a bit thicker than most other controllers, but it’s not that noticeable. The hardware and engineering that went into this controller is remarkable.

What I don’t like about the Stealth Pivot

There are some compromises that come with this quick-switch capability, however. The first is that Turtle Beach wasn’t able to include its microswitch buttons, which personally I prefer over the more standard buttons on the Pivot. The joysticks are still Hall Effect, which is nice, but the rest of the buttons are standard. The buttons aren’t bad, they just aren’t as good as on the company’s other pro controller.

Secondly, making room for those rotating gamepads means space had to come from somewhere and the most obvious place was the battery. Turtle Beach says the Pivot gets about 20 hours of battery life, which is probably a bit optimistic. I wouldn’t say it’s terrible, but it’s not great. This is somewhat mitigated by the fact that you have to be physically plugged into your Xbox anyway, and you can play while charging — but PC users may want to keep a cable handy.

Also, while you can use the company’s Control Center II app to customize the controller on Windows, Xbox, iOS and Android, the app itself is not very good. The UI is basic and there are some annoying bugs including the inability to rename profiles on the Xbox version. It’s also hard to tell if anything saves after you make changes. There’s no indicator or save button anywhere, and while it does save things in real-time, it would be nice if it let you know it’s happening.

Lastly, it’s disappointing that you can’t connect wirelessly to the Xbox. Wired is fine, and it avoids battery issues, but wireless is obviously more convenient.

Should you buy the Stealth Pivot?

The Stealth Pivot is a really solid controller even without the dual personalities. Personally, I’m not really into fighting games so I don’t need the second set of controls. And super hard-core, e-sport-level gamers would probably want something like a Fight Stick or a more dedicated fighting game controller.

However, if you’re a more casual gamer who enjoys fighting/button heavy games alongside games that use joysticks — and wants to level up your fighting style — the Stealth Pivot might be worth a look, especially since it’s only $130. That is more expensive than a standard controller, but for everything you get with it, that’s a hard price to beat.
