Samsung Galaxy S25 Edge vs. iPhone Air: Which Ultra-Thin Flagship Wins in 2026?

Samsung’s Galaxy S25 Edge and Apple’s iPhone Air are the two thinnest flagship smartphones you can buy right now in 2026. Samsung launched the S25 Edge on May 30, 2025, at $1,099.99, while Apple followed with the iPhone Air on September 19, 2025, starting at $999. Both phones target buyers who want a premium, ultra-slim device â but they make very different trade-offs to get there.

Note: Samsung originally teased this device under the “Galaxy S25 Slim” name before officially branding it the Galaxy S25 Edge at Galaxy Unpacked in January 2025.

Design and Build Quality

Both phones chase the same goal â flagship specs in the thinnest possible body â but they get there differently.

The Galaxy S25 Edge measures 5.8 mm thick with a titanium frame and Corning Gorilla Glass Ceramic 2 on the front. At 163 grams, it is remarkably light for a 6.7-inch phone. Samsung’s design language carries forward the flat-edge aesthetic from the S25 Ultra, and the phone feels substantial despite its slim profile.

The iPhone Air edges ahead on thinness at 5.6 mm, making it the thinnest iPhone ever made. It weighs 165 grams â slightly heavier than the S25 Edge despite having a smaller 6.5-inch screen. Apple uses its signature aluminum and glass construction. The design is clean and minimal, with a single camera lens on the back instead of the usual multi-lens array.

In hand, both phones feel dramatically different from standard flagships. If you have been using a Galaxy S25 Ultra (8.2 mm) or iPhone 17 Pro Max, the difference is immediately noticeable.

Display

Samsung wins the display comparison. The Galaxy S25 Edge features a 6.7-inch Dynamic AMOLED 2X panel with a sharp 1440 x 3120 resolution and peak brightness of 2,600 nits. The adaptive refresh rate scales from 1Hz to 120Hz, which helps with battery efficiency.

The iPhone Air’s 6.5-inch Super Retina XDR display is excellent by any standard, with ProMotion 120Hz support. However, it does not match the S25 Edge’s peak brightness or resolution. For outdoor readability and HDR content, the Samsung has a clear edge (no pun intended).

Camera: Samsung’s Biggest Advantage

This is where the Galaxy S25 Edge pulls ahead decisively. Its 200 MP main sensor â the same one found in the Galaxy S25 Ultra â delivers stunning detail, excellent dynamic range, and strong low-light performance. Samsung’s Night Video mode captures usable footage in conditions where most phones struggle. The secondary 12 MP ultrawide lens handles group shots and landscapes adequately, though the lack of a telephoto lens (which the S25 Ultra has) is a notable omission for a $1,100 phone.

The iPhone Air takes a minimalist approach with a single 48 MP rear camera. Apple claims its computational photography pipeline makes this one lens function like four, and the results in good lighting are genuinely impressive. However, in direct comparison, the S25 Edge’s 200 MP sensor resolves more detail, handles noise better in low light, and offers more versatility for cropping.

If camera quality matters to you, the Galaxy S25 Edge is the clear winner.

Performance

Both phones use top-tier processors and handle everyday tasks, gaming, and multitasking without breaking a sweat.

The Galaxy S25 Edge runs the Snapdragon 8 Elite for Galaxy with 12 GB of RAM. This is the same chip powering the S25 Ultra, and it delivers flagship-class performance across the board. Samsung’s Galaxy AI features â including on-device translation, Circle to Search, and generative editing tools â run smoothly.

The iPhone Air uses Apple’s A19 Pro alongside the N1 neural engine and C1X camera processing chip. Apple’s silicon continues to lead in single-core CPU performance and power efficiency. iOS 18 with Apple Intelligence provides its own suite of AI features, including writing tools, image generation, and Siri improvements.

In real-world usage, most people will not notice a meaningful performance difference between these two phones. Both are fast.

Battery Life: The Achilles’ Heel

Battery life is the biggest compromise both phones make for their slim designs, but the Galaxy S25 Edge suffers more.

The S25 Edge packs a 3,900 mAh battery â actually smaller than the standard Galaxy S25’s 4,000 mAh cell. Reviews consistently report that the S25 Edge struggles to last a full day with moderate to heavy use. With 2-3 hours of screen-on time being typical under heavier workloads, power users will need to charge midday. The 25W wired charging helps, reaching about 50% in 30 minutes.

The iPhone Air performs slightly better in battery endurance. Apple claims 22 hours of video playback, and real-world usage generally gets most users through a full day with light to moderate use. Apple’s power-efficient A19 Pro chip helps compensate for the smaller battery.

Neither phone is a battery champion. If all-day battery life is non-negotiable for you, consider the standard Galaxy S25+ or iPhone 17 Pro instead.

Software and AI Features

The Galaxy S25 Edge runs Android 16 with Samsung’s One UI 7 overlay. Samsung promises seven years of OS updates and security patches, which means support through 2032. Galaxy AI features include live translation during phone calls, Circle to Search, generative photo editing, and Note Assist for summarizing text.

The iPhone Air runs iOS 18 with Apple Intelligence. Apple’s AI features include system-wide writing tools, Genmoji (custom emoji generation), Image Playground for creating images from prompts, and a significantly improved Siri that can understand context across apps. Apple’s update track record is excellent, with typical support lasting 6-7 years.

Both ecosystems are mature and capable. Your preference here likely depends on which platform you already use.

Pricing and Value

The iPhone Air starts at $999 for 256GB, with a 512GB option at $1,199 and 1TB at $1,399. The Galaxy S25 Edge starts at $1,099.99 for 256GB and $1,219.99 for 512GB (no 1TB option).

At the 256GB tier, the iPhone Air is $100 cheaper. At 512GB, the price difference narrows to about $20. If you need 1TB of storage, only Apple offers that option in this form factor.

Our Recommendation

Buy the Samsung Galaxy S25 Edge if: You prioritize camera quality, want the best display, prefer Android, or need a physical SIM card slot. The 200 MP camera system is in a different league from the iPhone Air’s single lens, and the 6.7-inch AMOLED display is gorgeous.

Buy the iPhone Air if: You are already invested in the Apple ecosystem, want the thinnest possible phone (5.6 mm vs. 5.8 mm), prefer a lower starting price, or need up to 1TB of storage. The single-camera system is a trade-off, but Apple’s computational photography partially bridges the gap.

Buy neither if: Battery life is your top priority. Both phones sacrifice endurance for thinness. The Galaxy S25+ ($999.99), Galaxy S25 Ultra ($1,299.99), or iPhone 17 Pro ($1,099) deliver better all-day battery performance without the ultra-slim compromises.
