Thickness face-off
The iPhone Air measures just 5.64 mm, making it slightly slimmer than the Galaxy S25 Edge’s 5.8 mm frame. That 0.2 mm may sound minor, but it gives the iPhone a more refined and lightweight feel in the hand.
Its flat, even surface enhances grip comfort, while Samsung’s curved edges make the S25 Edge appear more fluid but just a touch thicker when viewed from the side.
Weight and ergonomics
Both phones redefine portability. The iPhone Air weighs 165 grams, while the Galaxy S25 Edge comes in a hair lighter at 163 grams.
The minimal difference doesn’t change everyday comfort, but the feel varies. Apple’s flatter body feels sturdy and balanced, whereas Samsung’s subtle curves mold better to the palm. Each device offers excellent pocketability and balance, reflecting two distinct design philosophies for thin, lightweight flagships.
Build and materials
Apple built the iPhone Air around a titanium frame with Ceramic Shield 2 glass, giving it a sleek yet durable exterior.
Samsung’s S25 Edge also uses titanium, complemented by Gorilla Glass Ceramic 2 for enhanced resilience. Both are IP68-rated for water and dust resistance. The difference lies in texture. Apple’s brushed finish feels colder and more premium, while Samsung’s soft-touch coating adds warmth and smoother transitions along the edges.
Display tech and size
The iPhone Air features a 6.5-inch OLED panel with up to 3,000 nits of brightness and a smooth 120 Hz refresh rate, offering crisp visuals even in bright outdoor conditions.
Samsung’s Galaxy S25 Edge expands slightly to 6.7 inches with a QHD+ AMOLED screen and similar 120 Hz fluidity. While the iPhone shows better glare control, Samsung’s display produces richer color saturation and deeper contrast, appealing to users who prefer vivid, cinematic visuals.
Camera setup rear
Apple’s iPhone Air uses a single 48-megapixel sensor that delivers sharp images and 2× lossless zoom through intelligent cropping. Samsung’s S25 Edge, on the other hand, features a 200-megapixel primary lens and a 12-megapixel ultrawide camera, providing it with significantly more flexibility for landscape and wide-angle photography.
The iPhone prioritizes simplicity and efficiency, while Samsung leans toward versatility and professional-style framing for photography enthusiasts.
Video capabilities
The iPhone Air records in 4K HDR up to 60 frames per second with excellent stabilization and Dolby Vision support. The Galaxy S25 Edge takes it further with 8K video at 30 fps and broader framing through its ultrawide lens.
The iPhone produces smoother transitions and consistently sharp images when zooming, while Samsung’s camera captures more expansive shots. Each phone shines in its own way: Apple for cinematic polish, Samsung for creative freedom.
Performance and thermals
The iPhone Air runs on Apple’s A19 Pro chip, paired with 12 GB of RAM, offering lightning-fast single-core speeds and excellent thermal control. Samsung’s Galaxy S25 Edge utilizes the Snapdragon 8 Elite for Galaxy, paired with 12 GB of RAM, to deliver top-tier multitasking and GPU performance.
In longer sessions, the iPhone stays more stable under heat, while Samsung’s processor briefly peaks higher before throttling, giving users a trade-off between sustained smoothness and short bursts of power.
Battery capacity and efficiency
The iPhone Air carries a 3,149 mAh battery, while the Galaxy S25 Edge holds a larger 3,900 mAh cell. Despite the smaller size, Apple’s power efficiency from the A19 Pro chip keeps it competitive, extending screen-on time beyond what its numbers suggest.
Samsung’s larger cell phone is better suited for heavy users, especially those who engage in gaming or media streaming, but Apple’s combination of hardware and software optimization keeps the Air surprisingly close in terms of endurance.
Charging speeds and wireless
The iPhone Air supports 20-watt wired charging and up to 20-watt MagSafe or Qi2 wireless charging, ideal for fast top-ups. Samsung’s S25 Edge pushes ahead slightly with 25-watt wired and 15-watt wireless speeds, though it needs a compatible case for magnetic alignment. In practice, both reach roughly 50 percent in half an hour.
Samsung’s edge in raw wattage is slight, but Apple’s unified ecosystem makes wireless charging more convenient and consistent.
Software and update policy
The iPhone Air runs on iOS 26, bringing Liquid Glass UI, Visual Intelligence, and improved Hold Assist features. Apple guarantees five years of software updates with strong integration across its ecosystem.
Samsung’s S25 Edge runs One UI 7, based on Android 15, and promises seven years of significant updates. Its AI-driven features, like Galaxy AI and DeX desktop mode, cater to productivity-minded users. Apple’s interface feels polished and minimal, while Samsung’s stands out for customization and longevity.
Connectivity and ports
Apple’s iPhone Air includes USB-C 2.0, Wi-Fi 7, Bluetooth 6, and Thread support, but lacks mmWave 5G compatibility. Samsung’s S25 Edge steps up with USB-C 3.2 and full 5G support across mmWave and sub-6 bands, plus Bluetooth 5.4 and Wi-Fi 7.
Users who rely on faster data and broader carrier coverage will find Samsung more flexible, while Apple focuses on streamlined integration within its devices over peak transfer speeds.
Thermal and stability trade-offs
During performance stress tests, the iPhone Air maintains 65% stability after 20 minutes and around 58% after 40 minutes, keeping temperatures in check.
The Galaxy S25 Edge drops to the low 40s in terms of stability under extended workloads, exhibiting quicker thermal throttling. Both phones heat up during gaming, but Apple’s cooling and software management provide steadier long-term output, making it more consistent for extended use without sudden slowdowns.
Price and value perspective
The iPhone Air starts at $999, while the Galaxy S25 Edge begins at $1,099. Samsung’s device offers more camera options, faster connectivity, and stereo sound for its price, often available at a discount during sales. The iPhone’s appeal lies in its iconic design and ecosystem efficiency.
Both deliver luxury experiences, but Samsung provides slightly better value for performance seekers, while Apple caters to users who prize refined elegance.
Ideal user profiles
The iPhone Air is designed for users who value simplicity, extreme thinness, and seamless integration across Apple devices. It’s perfect for those prioritizing aesthetics and daily comfort.
The Galaxy S25 Edge suits power users who want a premium design without compromising flexibility, offering stronger cameras, connectivity, and sound. Each phone targets different lifestyles: Apple’s minimalist charm versus Samsung’s feature-rich versatility for users who require more functionality in a single device.
Who wins the thinnest battle
By the numbers, the iPhone Air takes the title of world’s thinnest flagship at 5.64 mm, just edging out the 5.8 mm Galaxy S25 Edge. Yet, Samsung counters with a greater balance of hardware and everyday practicality.
Apple wins the design statement, offering the sleeker body, while Samsung wins the usability crown. The competition proves that thin doesn’t mean limited, it’s about how each brand defines premium portability.
Is Apple preparing to go ultra-thin? The speculated iPhone 17 Air might revolutionize everything, including style and cost.
Final verdict and recommendation
The iPhone Air narrowly claims victory for design innovation and consistent performance in an ultra-slim package. Its craftsmanship and efficiency make it a milestone in minimal smartphone engineering.
Still, the Galaxy S25 Edge remains a powerhouse with superior versatility, audio, and display range. The ultimate choice depends on preference: Apple for elegance and stability, Samsung for practicality and all-around functionality.
