When Samsung announced the Galaxy S25 Edge on May 13, 2025, it piqued curiosity as the company's thinnest flagship to date. At just 5.8 mm thick and weighing ≈163–168 g, it feels more like holding a sheet of paper than a powerhouse smartphone. But beyond aesthetics, does the S25 Edge hold up as a top-tier device? Let’s dive in.

Design: Lightweight Meets Titanium Elegance

Featherlight and thin. At 5.8 mm thick—about as thick as seven credit cards stacked and weighing just 163 168 g, it's a remarkable engineering feat.

Premium materials. The titanium frame paired with Gorilla Glass Ceramic 2 ensures durability without bulk.

Trade-offs. Its thin profile means most users will need to forgo protective cases to enjoy that sleek feel impacting drop protection .

While some critics argue it’s more flash than innovation ( hardly seems an engineering marvel ) most agree its feel in hand is genuinely new a bold lightweight flagship in an era of heavier devices.

Display & Hardware: Power Packed in Slim Form

Striking screen. A 6.7″ QHD+ LTPO AMOLED display hits nearly 2,600 nits peak brightness with 120 Hz refresh rate clear, vibrant, and responsive.

Same internal muscle as its siblings: Snapdragon 8 Elite, 12 GB RAM, 256/512 GB storage. Snappy performance from daily tasks to gaming.

Thermal management. Samsung reengineered the vapor chamber wider and thinner to control heat, though reviews note device warms with heavy use.

Camera: Stellar Main Shooter, Missing Zoom

200 MP main lens. Matches Ultra-level resolution, with stellar clarity even capturing astrophotography via Expert RAW.

Ultrawide included. A trusty 12 MP ultrawide covers wide scenes, though overall versatility is limited.

No telephoto camera. A noticeable omission for photo enthusiasts; zoom relies on digital cropping, lacking sharp detail of true optical zoom.

Battery & Charging: Light on Endurance

3,900 mAh battery. A slim sacrifice—runs around 12 hours in benchmarks, versus 17+ hours on Plus or Ultra.

Charging slower. Capped at 25 W wired and wireless, slower than the Plus/Ultra's 45 W.

Heat and battery hit. Running 3–5 °C warmer, it sheds battery quickly under heavy use.

Most users report a day's light to moderate use, but gamers or streamers may find it wanting.

Software & AI: The Full Galaxy Experience

One UI 7 atop Android 15, with Samsung’s full Galaxy AI suite—from Gemini to Audio Eraser

Now Bar, cross-app AI tools. Galaxy’s version of live tiles or dynamic islands enhances multitasking

Longevity promised. Seven years of OS/security updates mean this phone won’t become outdated anytime soon

Productivity boost with DeX. Lightweight and compact, yet capable of desktop-style workflow when docked

Who Is the S25 Edge For?

User Type	Recommendation
Design-focused users	Perfect: unparalleled thinness and style.
Day-to-day users	Good: solid screen, AI features, manageable battery.
Photography lovers	Not ideal: lacks optical zoom.
Heavy users/gamers	Better choices exist: battery and heat limitations.

TechRadar called it “razor-thin,” but not without compromises—battery life and camera versatility being core. Likewise, the Washington Post framed it as a market experiment—a design statement more than mass market phone

Final Verdict

The Galaxy S25 Edge stands out as Samsung’s slimmest flagship, delivering flagship-grade performance in an ultra-light build. If you’ve yearned for a powerful yet sleek phone, this answers that call. From a user-experience standpoint, it’s like carrying a high-performance computer in your pocket… without the typical heft.

But that elegance comes at a cost:

No optical zoom for photo enthusiasts.

Moderate battery that may disappoint heavy users.

Slower charging and thermal constraints.

If your top priorities are design, portability, and cutting-edge AI features, the S25 Edge is a compelling choice. But if you're after all-around endurance and camera versatility, the S25 Plus or Ultra offer better value.

The Galaxy S25 Edge isn't a jack-of-all-trades, but it confidently stakes its claim: the thinnest flagship on the market—no ifs, ands, or buts. It’s a bold experiment that blends elegance and power, packed with long-term software support and AI tools. Just be ready to trade a bit of battery life and camera breadth to carry artful design in your pocket.
