Thin Phone Battle: iPhone Air vs. Galaxy S25 Edge

Apple and Samsung are hoping some svelte-tightening of their phone designs will win over buyers who don’t need all the extras of their pro-level phones.

Although purely anecdotal, I’ve seen reports of people going into Apple retail stores intent on buying an iPhone 17 Pro — with its improved camera system, vapor chamber cooling system and of course that bright orange color — and then walking out with the slim iPhone Air instead. And when Samsung announced the Galaxy S25 and S25 Ultra, what caught everyone’s attention was the tease of a thinner model that was subsequently released as the Galaxy S25 Edge. If you’re unexpectedly considering a thinner phone, this seems to be the year to do it.

So how do these two slim phones compare? If you press them together, are they combined much thicker than a regular iPhone 17 or Galaxy S25? I’m here to do the math and compare features.

iPhone Air vs. S25 Edge price comparison

  • iPhone Air: $999. The iPhone Air takes the place formerly held by the iPhone 16 Plus, making it the only model with a screen larger than the iPhone 17 that isn’t an iPhone 17 Pro.

  • Galaxy S25 Edge: $1,100. The S25 Edge joins the S25 and S25 Ultra in this year’s Galaxy lineup.

The iPhone Air includes fewer features than the iPhone 17, such as the number of cameras. But it includes a larger display, an A19 Pro processor and is configured with 256GB of storage to start. Plus, Apple has always applied premium pricing for thin design changes. The original MacBook Air fit into an inter-office envelope and cost $1,799, despite being underpowered compared to the rest of the MacBook line. (Over a few generations, it would eventually become Apple’s entry-level affordable laptop at $999, where it still resides.)

The Galaxy S25 Edge’s higher price (of $101) could be an attempt to capture more dollars from customers who are looking for a phone that will set them apart, but we’re already seeing occasional steep discounts on it, like this $300 drop.

In both cases, it’s worth noting that the pricing has held up against the Trump administration tariffs so far.

iPhone Air vs. S25 Edge dimensions and weight

Now it’s time to go deep — as in, just how thin is the depth of each phone?

No phone manufacturer describes its phones as bulky or chunky, even for extra-large models like the iPhone Pro Max. Yet the difference between the depths of the iPhone Air and S25 Edge and the standard phones of each respective family is stark.

Not counting the camera assembly, which Apple calls the «plateau,» most of the iPhone Air’s body is 5.64mm thick. The S25 Edge, at its narrowest point, is a hair thicker at 5.8mm. (Both companies list only the thinnest measurement, not including the cameras.) Compare that to 7.9mm for the iPhone 17 and 7.2mm for the Galaxy S25.

The Galaxy Z Fold 7 is actually thinner when open, at 4.2mm, but it also has more surface area to spread out its battery and other components. Other foldables from Chinese companies Huawei, Oppo and Honor also boast thinner bodies than the iPhone Air or S25 Edge, but only when opened.

And when you press the two thin phones together, do they really match up to the typical phone slab you’re carrying now? Combined (and again, not including the camera bumps), the iPhone Air and S25 Ultra are 11.44mm thick, which is more chunky than either the iPhone 17 or Galaxy S25, and even the iPhone 17 Pro Max at 8.75mm. But if you wanted to get closer to an old-time feel, the original first-generation iPhone in 2007 sat at 11.6mm.

Surprisingly, less depth translates to only a little less weight compared to the other models in each lineup. The iPhone Air weighs 165 grams versus 177 grams for the iPhone 17, while the S25 Edge pips in at just 163 grams but gets barely undercut by the Galaxy S25 at 162 grams.

How big is each phone in the hand? While both are pretty similar, the iPhone Air is slightly shorter and narrower at 156.2mm tall and 74.7mm wide, compared to the S25 Edge’s dimensions of 158.2mm tall and 75.6mm wide.

iPhone Air vs. S25 Edge displays

Apple calls the iPhone Air’s 6.5-inch OLED screen a Super Retina XDR display. It has a high resolution of 2,736×1,260 pixels at a density of 460 ppi (pixels per inch) and can output a maximum of 3,000 nits of brightness outdoors and just 1 nit minimum in the dark.

Samsung packed a larger 6.7-inch QHD+ Dynamic AMOLED 2X screen into the S25 Edge, which translates to a high-resolution display measuring 3,120 x 1,440 pixels at 513 ppi. Its brightness goes up to 2,600 nits.

Both phones’ screens feature adaptive 120Hz refresh rates for smoother performance.

Comparing the iPhone Air and S25 Edge cameras

So far, many of the specs have been close enough to weigh each phone fairly evenly. But then we get to the cameras.

The iPhone Air includes a single rear-facing 48-megapixel wide camera with a 26mm-equivalent field of view and a constant f/1.6 aperture. In its default mode, the camera outputs 24-megapixel «fusion» photos that are the result of an imaging process where the camera captures a 12-megapixel image (using groups of four pixels acting as one larger pixel for better light gathering, called «binning») and a 48-megapixel reference for additional detail.

Apple also claims the iPhone Air can capture 2x-zoomed (52mm-equivalent) telephoto images that are 12 megapixels in dimension and represent a crop of the center of the image sensor.

The S25 Edge includes two built-in rear cameras, a 200-megapixel wide and a 12-megapixel ultrawide. There’s no dedicated telephoto camera, so the S25 Edge also offers a 2x-zoomed crop that shoots photos at 12 megapixels in size.

The front-facing selfie cameras on each phone are quite different. The iPhone Air introduces a new 18-megapixel camera with an f/1.9 aperture. But the increased resolution over the S25 Edge’s 12-megapixel selfie camera isn’t what’s notable. Apple calls it a Center Stage camera because it has a square sensor that can capture tall or wide shots without physically turning the phone, compared to the 4:3 ratio sensors in typical selfie cameras. It can adapt the aspect ratio based on the number of people it detects in front of the camera: a traditional portrait orientation when you’re snapping a photo of yourself, for example, or switch to a landscape orientation when two friends stand next to you in the frame.

iPhone Air vs. S25 Edge batteries

When it comes to concerns, the battery life of thin phones tops the list. The insides of most phones are packed with as much battery as will fit, so making a phone slimmer naturally means removing space for the battery. With either model, you end up sacrificing battery power for design. But how much?

Apple doesn’t list the iPhone Air’s battery capacity, but claims «all-day battery life» and up to 27 hours of video playback. It also sells a special iPhone Air MagSafe Battery add-on that magnetically snaps to the back of the phone and works only with the iPhone Air. In her review, CNET’s Senior Tech Reporter Abrar Al-Heeti drained the battery in 12 hours over a phone-intensive day, but did end a more typical day with 20% remaining.

The S25 Edge includes a 3,900-mAh battery that Samsung claims will play up to 24 hours of video playback. (Come on, phone manufacturers, our phones aren’t televisions left running in the background.) 

In her S25 Edge review, Al-Heeti noted that the phone also generally lived up to Samsung’s own «all-day battery life» boast, saying, «Ultimately, you’ll get less juice out of that slimmer build, but S25 Edge offers just enough battery life to make me happy…But the S25 Edge has shifted my priorities. I’m enjoying the sleek form factor so much that I’m willing to make some compromises, even if that means I have to be sure to charge my phone each night, which is something I tend to do anyway.»

It’s worth noting that both phones support fast charging when using a 20-watt or higher wired power adapter, going from zero to around 50% charge in 30 minutes.

iPhone Air vs. S25 Edge processor, storage and operating system

The iPhone Air is powered by Apple’s latest A19 Pro processor, the same one found in the iPhone 17 Pro models (compared to the A19 in the stock iPhone 17). Apple doesn’t list the built-in memory, but we suspect it includes 8GB of RAM (which is recognized as the minimum amount to run AI features such as Apple Intelligence). The base storage configuration is 256GB, with options to order the iPhone Air with 512GB or 1TB capacity. It ships with iOS 26, the latest version of the operating system that Apple released widely this week.

The S25 Edge runs on a Snapdragon 8 Elite processor, the same one that powers the other S25 models. It includes 12GB of RAM and is available in storage capacities of 256GB and 512GB. The phone comes preinstalled with Android 15.

Judge Blocks Texas App Store Age-Check Law

A preliminary injunction found the Texas law, set to begin Jan. 1, is «more likely than not unconstitutional.»

A new Texas state law set to take effect on Jan. 1 would have required app stores to implement age verification processes. But the law has been put on hold, at least temporarily, by a federal court judge.

As reported by the Texas Tribune, Senate Bill 2420, also known as the Texas App Store Accountability Act, is the subject of a temporary injunction issued by US District Judge Robert Pitman.

Pitman said in his decision that the law as written is broad, vague and «more likely than not unconstitutional.» However, he also wrote the court «recognizes the importance of ongoing efforts to better safeguard children when they are on their devices.»

The Texas law, signed into law by Governor Greg Abbott in May, requires app store operators — including Apple, Google, Nintendo, Steam and more — to build age verification processes for the storefronts and to only allow downloads to minors who obtain parental consent. The injunction is a ruling in an October lawsuit filed by the Computer & Communication Industry Association.

CCIA senior vice president Stephanie Joyce said in a statement, «This Order stops the Texas App Store Accountability Act from taking effect in order to preserve the First Amendment rights of app stores, app developers, parents, and younger internet users. It also protects parents’ inviolate right to use their own judgment in safeguarding their children online using the myriad tools our members provide.»

Other individuals and the advocacy group Students Engaged in Advancing Texas also filed suits over the law, the Texas Tribune reported.

App Store Accountability Act

The bill author, State Senator Angela Paxton, said the bill was meant to give parents «common sense tools to protect their kids and to survive court challenges by those who may have lesser priorities.»

The language of Texas Senate Bill 2420 does not only include mobile app stores from Apple or Google, but any «website, software application, or other electronic service that distributes software applications from the owner or developer of a software application to the user of a mobile device.»

By that definition, websites with links to browser games or mobile game consoles with download options would fall under the Texas law as written. The law also defines mobile devices as including phones and tablets, as well as any other handheld device capable of transmitting or storing information wirelessly.

The parental consent aspect of the law requires those under 18 to have an app store account affiliated with a parent or guardian to purchase or download applications.

Age verification elsewhere

In an effort to keep adult materials out of reach of minors and to protect children from potentially harmful content and interactions, tech companies have been compelled by law or through legal action to verify the age of users.

Roblox, which has a huge audience of minors, began rolling out stricter age verification after investigations and lawsuits hurt its reputation as a safe gaming space. Australia is perhaps the most large-scale example of a government restricting access to online content. In December, Australia began restricting social media access to those 16 and older. Reddit recently challenged that law.

In the US, age verification laws have primarily targeted adult sites. Texas already has a law on the books that requires adult sites to age-block their content. The Supreme Court upheld that law in a June ruling. The UK has also enacted age restriction rules for adult sites as have other US states.

Don’t Let a Border Agent Ruin Your Holiday Trip. Travel With a Burner Phone

Yes, you should leave your main phone at home and take a cheap burner this winter.

Prepare for a whole new level of border-crossing anxiety this holiday season: the high-probability of a phone search. New figures from US Customs and Border Protection say agents aren’t just glancing at your lock screen anymore — they are aggressively ramping up device inspections, even for citizens coming home. We aren’t just talking about a quick scroll through your photos, either. Agents are increasingly using forensic tools to clone and analyze everything on your device.

The stats are genuinely alarming. In just a three-month window this year, nearly 15,000 devices were flagged for searches, with over a thousand subjected to deep-dive data copying. If you’re traveling with your primary phone, you are essentially carrying your entire digital existence into a legal gray zone where privacy is optional.

The smartest defensive play is remarkably low-tech: the burner phone. By traveling with a secondary, stripped-down device, you ensure your private data stays safe at home while you stay connected abroad. But privacy isn’t the only perk. Moving to a «dumb» phone is the ultimate digital detox, helping you escape the notification trap that usually ruins a vacation.

Even figures like Conan O’Brien have ditched the smartphone to cut through the noise. Whether you’re dodging invasive border searches or just trying to enjoy your trip without being glued to a screen, a burner might be the best travel investment you make this year.

Although carriers have offered prepaid phones since the ’90s, «burner phones» or «burners» became popular in the 2000s following the celebrated HBO series The Wire, where they helped characters avoid getting caught by the police. Although often portrayed in that light, burners aren’t only used by criminals; they’re also used anyone concerned with surveillance or privacy infringement.

What is a burner phone, and how does it work? Here’s everything you need to know about burners and how to get one.


Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.


What is a burner phone?

A burner phone is a cheap prepaid phone with no commitments. It comes with a set number of prepaid call minutes, text messages or data, and it’s designed to be disposed of after use.

Burner phones are typically used when you need a phone quickly, without intentions of long-term use. They’re contract-free, and you can grab them off the counter. They’re called burner phones because you can «burn» them (trash them) after use, and the phone can’t be traced back to you, which makes them appealing to criminals. Of course, those committed to illicit activities often do more than just throw these phones in the trash, and often completely obliterate the SIM cards and other materials by smashing them with a hammer or melting them away. 

Burners are different from getting a regular, contract-bound cellphone plan that requires your information to be on file. 

Why should you use a burner phone?

Burner phones are an easy way to avoid cellphone contracts or spam that you get on your primary phone number. Burners aren’t linked to your identity, so you can avoid being tracked down or contacted.

You don’t have to dispose of a burner phone after use. You can add more minutes and continue using it. Burner phones can still function as regular phones, minus the hassle of a contract.

You can also get a burner phone as a secondary phone for a specific purpose, like having a spare phone number for two-factor authentication texts, for business or to avoid roaming charges while traveling. Burner phones are often used by anyone concerned with privacy.

Burner phones, prepaid phones, smartphones and burner SIMs: What’s the difference? 

Burner phones are cheap phones with simple designs that lack the bells and whistles of a smartphone. Because they’re designed to be disposable, you only get the essentials, as seen by the most common version, the flip phone.

All burner phones are prepaid phones, but not all prepaid phones are burners. What sets a burner apart is that you won’t have to give away any personal information to get one, and it won’t be traceable back to you. Again, a burner phone is cheap enough to be destroyed after use.

Prepaid smartphones are generally low-end models. You can use any unlocked smartphone with prepaid SIM cards, essentially making it a prepaid phone.

If you want a burner, you don’t necessarily have to buy a new phone. You can get a burner SIM and use it with an existing phone. Burner SIMs are prepaid SIMs you can get without a contract or giving away personal information.

Where can you buy a burner phone?

Burner phones are available at all major retail outlets, including Best Buy, Target and Walmart. They’re also often available at convenience stores like 7-Eleven, local supermarkets, gas stations and retail phone outlets like Cricket and Metro.

You can get a burner phone with cash, and it should cost between $10 and $50, although it may cost more if you get more minutes and data. If you’re getting a burner phone specifically to avoid having the phone traced back to you, it makes sense to pay with cash instead of a credit card.

If you just want a prepaid secondary phone, you can use a credit card. Just keep in mind that credit cards leave a trail that leads back to you.

There are also many apps that let you get secondary phone numbers, including Google Fi and the Burner app. However, these aren’t burners necessarily because the providers typically have at least some of your personal information. Additionally, apps like Google Talk require a phone number that’s already in use for you to choose a number with the service.
