The S25 Edge has quickly become one of Samsung’s most talked-about smartphones — and not because it packs another incremental hardware bump. It’s because this phone dares to challenge an unspoken rule of the modern flagship world: thicker is better. In an era where most devices chase bigger batteries and massive camera arrays, Samsung has done something refreshingly bold. The S25 Edge strips down the excess and presents itself as a masterclass in minimalism — an ultra-thin, featherweight flagship that turns heads for its sheer elegance.
But this approach comes with risks. By pushing the boundaries of thinness, Samsung also flirts with the trade-offs that could make or break the experience. So, does the S25 Edge represent the future of sleek smartphone design, or has Samsung sacrificed too much on the altar of slimness?
Let’s dive deep.
Design and Build: Where the S25 Edge Defies Gravity
At just 5.8 mm thin, the S25 Edge is stunningly slim — almost pencil-thin and noticeably sleeker than even the S25 Ultra’s 8.2 mm frame. The first impression when holding it is almost surreal. It feels impossibly light at 163 grams, yet reassuringly solid. Many early users have described it as “a sheet of metal that disappears in your hand,” which sums up Samsung’s engineering intent perfectly — to make technology vanish into elegance.
Despite its minimalist form, the S25 Edge is not a fragile showpiece. The titanium frame adds structural rigidity, while Gorilla Glass Ceramic 2 on the front and Victus 2 on the back ensure scratch and impact resistance. It also retains an IP68 rating, meaning dust and water are non-issues.
However, the phone’s ultra-thin design introduces one unavoidable side effect — the camera bump. It protrudes quite prominently, creating what reviewers humorously call “table wobble.” It’s a small aesthetic flaw in an otherwise breathtaking design, and one that subtly reminds you how far Samsung has gone to compress the rest of the chassis.
Still, there’s no denying that the S25 Edge feels futuristic. It’s the kind of phone that makes you rethink what a flagship should feel like.
Display: Samsung’s Visual Brilliance in a Slim Frame
The S25 Edge carries a 6.7-inch Dynamic AMOLED 2X display with Quad HD+ (1440p) resolution and an LTPO 120Hz refresh rate, dynamically adjusting from 1Hz to 120Hz for optimal smoothness and efficiency. It’s bright — hitting up to 2600 nits peak brightness — and produces crisp, vivid colors with excellent contrast levels, even in direct sunlight.
Although Samsung skipped the anti-reflective coating found on the S25 Ultra, the visual experience here remains flagship-grade. Watching HDR content or gaming on this display feels fluid and immersive, aided by slim bezels that make the visuals stretch edge-to-edge.
The S25 Edge also integrates an ultrasonic fingerprint scanner beneath the screen, which is fast, secure, and effortless. And despite the limited internal space, Samsung managed to deliver stereo speakers that sound surprisingly rich and loud. Audio separation is solid, and while bass isn’t as deep as on the Ultra, it’s well-balanced for music, calls, and video playback.
For a device this thin, multimedia on the S25 Edge feels astonishingly premium.
Performance and Thermals: Slim Doesn’t Mean Weak
The S25 Edge might look delicate, but performance-wise, it’s a beast. Powering the device is the Snapdragon 8 Elite processor paired with 12GB LPDDR5X RAM and 256GB UFS 4.0 storage.
Benchmark numbers tell part of the story — scoring over 2 million on Antutu and close to 10,000 on Geekbench multi-core — but it’s the real-world performance that stands out. Everyday tasks feel instantaneous, animations are buttery smooth, and apps load with zero hesitation.
Samsung has also engineered clever ways to keep heat under control despite the phone’s slim frame. The vapor chamber cooling, thermal tape system, and new Tatim thermal insulator distribute heat efficiently. Even in long gaming sessions with Genshin Impact, the S25 Edge maintained stable frame rates (around 59–60 FPS) with minimal throttling, peaking at around 43°C — impressive for such a thin device.
Of course, it can get warm during extended gaming or multitasking, but not uncomfortably so. Samsung’s heat management is genuinely praiseworthy here — this is one of the best-optimized ultra-thin phones ever made.
Software and AI: One UI 7 Meets Galaxy AI
Out of the box, the S25 Edge runs One UI 7 based on Android 15, featuring Samsung’s polished and intuitive software experience.
Samsung also leads in longevity — promising 7 years of OS and security updates, matching Google’s own software policy. That means your S25 Edge will remain supported until well into the 2030s, making it a safe long-term investment.
On the AI front, the S25 Edge feels smarter than ever:
Circle to Search lets you quickly find anything on-screen by circling it.
AI Eraser and Generative Edit make photo editing effortless.
AI Keyboard corrects tone, grammar, and writing style in real time.
Live Translate and Now Briefing make travel and multitasking seamless.
Gemini Live integration even allows the phone to “see” through the camera and describe or identify objects in real time — a glimpse into the AI-driven future of smartphones.
In short, the S25 Edge is not just about thinness — it’s also about intelligence.
Camera: A Premium Sensor with a Missing Piece
Here’s where the S25 Edge both shines and stumbles. It features a 200MP primary camera, the same flagship sensor used in the S25 Ultra, paired with a 12MP ultrawide lens.
Photos from the main sensor are excellent — crisp, colorful, and full of detail. The larger sensor captures 44% more light than the S25 Plus, leading to great low-light performance and dynamic range. The 12MP ultrawide camera, meanwhile, handles macro and scenic shots decently with consistent color calibration.
The 12MP selfie camera performs well too, producing natural skin tones and sharpness that stands out in video calls and selfies alike.
However, the lack of a dedicated telephoto lens is a missed opportunity. Zooming beyond 2x relies on digital processing, which works fine for casual shots but falls short for photography enthusiasts who expect the versatility of a triple-lens setup.
Still, with 8K video at 30fps, 4K HDR recording, and Pro Video Mode, the S25 Edge remains a strong contender in videography. It’s just not a photographer’s dream — and Samsung seems to know that.
Battery Life: The Price of Thinness
Here’s the elephant in the room — battery life. The S25 Edge comes with a modest 3,900 mAh battery, and that slim body doesn’t leave much room for more.
In daily usage, expect about 4.5 to 5 hours of screen-on time, which is decent for moderate use but underwhelming for heavy multitaskers or gamers. If you’re streaming, gaming, or navigating frequently, you’ll need to top up by late evening.
Charging is capped at 25W wired, which takes roughly 75 minutes for a full charge. It supports 15W wireless charging and 7.5W reverse wireless charging, but these are more about convenience than speed.
Samsung could have truly nailed this phone with silicon-carbon battery tech, but the S25 Edge still sticks to traditional lithium-ion. It’s a reminder that physics, not ambition, is often the ultimate limitation.
Verdict: The S25 Edge Is Not for Everyone — and That’s the Point
At a price of ₹1,01,999, the S25 Edge is not just another flagship; it’s a statement. It’s for those who appreciate elegance, minimalism, and cutting-edge engineering more than brute specs.
The S25 Edge doesn’t aim to please everyone. It’s designed for people who value comfort, pocketability, and sleekness — those who want a phone that feels premium without the bulk. If you live in a world of wireless chargers, light workloads, and aesthetic priorities, this phone might just feel perfect.
However, power users who prioritize endurance, camera versatility, or all-day gaming might find the S25 Ultra a better fit.
Ultimately, the S25 Edge is one of those rare devices that dares to be different. It’s not the best phone for everyone — but it might be the most intriguing one for those who crave design perfection.
