Samsung Electronics on May 13 unveiled the Galaxy S25 Edge, a new addition to its flagship smartphone lineup that combines a refined, streamlined design with high-end performance.
While the device retains the same core specifications as the Galaxy S25 launched in January, it stands out with a 19% thinner body and a lighter body, signaling the company’s renewed focus on ultra-slim design.
The Galaxy S25 Edge marks Samsung’s first major flagship launch in five years since the debut of the Galaxy Z Flip in 2020. The company introduced the new model at a virtual event held at 9 a.m. through its official website and other online platforms.
Samsung described the device as “the slimmest yet most powerful and durable phone in the history of the Galaxy S series,” highlighting its role in reshaping industry trends.
In recent years, smartphones have steadily grown larger and heavier, driven by demand for bigger screens and more powerful features.
However, with meaningful performance gains becoming harder to achieve and market growth slowing, manufacturers like Samsung and Apple are shifting gears. Their latest strategy: delivering flagship-level capabilities in a slimmer, more compact design.
Samsung’s move with the S25 Edge is expected to ignite a new wave of competition in ultra-thin smartphones. Later this year, the company plans to release a more compact Galaxy Z Fold, while Apple is also rumored to unveil its own ultra-slim model—the “iPhone 17 Air”—in September.
Measuring just 5.8 millimeters thick and weighing 163 grams, the Galaxy S25 Edge is the slimmest and lightest model in the Galaxy S series to date.
Compared to the Galaxy S25 Ultra—which was released in January and measures 8.2 millimeters thick and weighs 218 grams—the Edge is 2.4 millimeters thinner and 55 grams lighter. Even the standard S25 model, previously the smallest in the lineup, is thicker at 7.2 millimeters.
To achieve this level of thinness, Samsung engineers reimagined the smartphone’s internal architecture from the ground up. Key components such as the camera, speaker, and vibration motor were redesigned to maintain their performance while significantly reducing their size.
“We rebuilt the 200-megapixel high-performance lens module to fit the slimmer body,” a Samsung official said. The company reportedly ran thousands of simulations during the redesign process to meet the device’s structural and performance targets.
New materials were introduced to lighten the overall weight while improving durability. Samsung also reconfigured the internal circuitry to minimize empty space between components, optimizing the use of limited internal volume.
Managing heat became a central challenge in reducing the device’s thickness. To address this, Samsung equipped the S25 Edge with a thinner yet wider vapor chamber than the one used in the Galaxy S24, allowing for more efficient heat dissipation.
Roh Tae-moon, head of Samsung’s mobile business, said the device represents “a perfect balance of design and engineering craftsmanship.”
Samsung emphasized that the S25 Edge preserves the premium aesthetic of the S25 lineup while adding new layers of durability. The front display is protected by Corning’s Gorilla Glass Ceramic 2—a next-generation reinforced glass designed to resist scratches and cracks in mobile devices.
The phone runs on Qualcomm’s Snapdragon 8 Gen 3 for Galaxy chip, the same high-performance processor used in the broader S25 series.
On the back, the S25 Edge features a dual-lens camera system, with a 200-megapixel wide-angle main lens—the same used in the S25 Ultra—and a 12-megapixel ultra-wide lens that supports both wide-angle and macro photography. However, unlike other S25 models, it does not include a telephoto lens.
The device comes in three color options: Titanium Silver, Titanium Jet Black, and Titanium Ice Blue. Pricing is set at 1,496,000 won ($1,058) for the 256GB model and $1,159 for the 512GB version, respectively. Preorders will run from May 14 to May 20, with official sales beginning May 23.
With the launch of the Galaxy S25 Edge, Samsung is aiming to lead the next phase of smartphone design innovation while reversing second-quarter sluggishness—typically a slow period for the industry. By positioning the Edge as a bridge between the first-quarter Galaxy S series and the third-quarter foldable Galaxy Z series, the company hopes to maintain momentum and fill what would otherwise be a seasonal sales gap.
