iPhone Air vs. Galaxy S25 Edge: Thin Phone Battle
If you’re looking for a less-chunky phone to carry all day, Apple and Samsung have new slim options. Here’s how they compare.
Super-thin phones carry a lot of appeal without a lot of bulk. They’re lighter than many counterparts, more comfortable to hold and let’s not forget how great they look. And although they remain a niche category, the Apple iPhone Air and Samsung Galaxy S25 Edge are also paving the way for the slim technology that makes the Galaxy Z Fold 7 and rumored iPhone Fold possible.
But are you giving up too much else for a slim phone? If you press them together, are they much thicker combined than a regular iPhone 17 or Galaxy S25Â (or the new Galaxy S26)? And do they overcome trade-offs in battery life, camera and sound quality that come with a thinner design? I’m here to do the math and compare features for you.

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. However, it features a larger display, an A19 Pro processor, and is equipped with 256GB of storage to begin with. Additionally, Apple has consistently applied premium pricing for minor 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 ($101) could be an attempt to capture more dollars from customers looking for a phone that sets them apart, but we’re already seeing occasional steep discounts on it.
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 the S25 Edge, as well as the standard phones of each respective family, is stark.
Not counting the camera assembly, which Apple refers to as 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 a larger surface area to accommodate its battery and other components. Other foldables from Chinese companies, such as 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, excluding the camera bumps), the iPhone Air and S25 Ultra are 11.44mm thick, which is thicker than either the iPhone 17 or Galaxy S25, and even the iPhone 17 Pro Max at 8.75mm. However, if you want to achieve a more vintage feel, the original first-generation iPhone, released in 2007, measured 11.6mm.
Surprisingly, the less depth translates to only a slight decrease in 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 similar, the iPhone Air is slightly shorter and narrower, measuring 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 features 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, as well as a minimum of 1 nit 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 3,120×1,440 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. 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 result from an imaging process where the camera captures a 12-megapixel image (using groups of four pixels acting as one larger pixel for improved light gathering, known as “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 features two built-in rear cameras: a 200-megapixel wide-angle lens and a 12-megapixel ultrawide lens. 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 differ significantly. 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.Â
Apple calls it a Center Stage camera because it features a square sensor that can capture tall or wide shots without requiring the user to physically turn the phone, unlike the 4:3 ratio sensors found 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 is at the top of 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 features a 3,900-mAh battery, which Samsung claims will support up to 24 hours of video playback. (Come on, phone manufacturers, our phones aren’t televisions left running in the background.)Â
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 used with a 20-watt or higher wired power adapter, allowing them to reach around 50% charge in 30 minutes from a completely discharged state.
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 is powered by 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.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration
European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.
BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.
The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.
Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.
However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.
Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.
European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge
Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.
Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.
Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.
The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.
Mortgage rates track the 10-year Treasury yield
Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.
In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.
Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.
If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.
But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.
There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.
That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.
Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.
CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.
“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.
AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.
GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.
Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.
In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.
And that’s leaving aside the deep animosity between the parties.
The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.
For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network
Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.
Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.
Kyiv has leveled accusations against SpaceX
Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.
Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.
Here’s an overview of Starshield and its distinctions from Starlink.
What is Starshield and how does it function?
Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.
SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.
In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.
SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.
On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.
How does Starshield contrast with Starlink?
While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.
Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.
Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.
SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
