Samsung Galaxy S25 Edge: The Thinnest Galaxy Phone Ever — Complete Review
The Samsung Galaxy S25 Edge pushes the boundaries of smartphone design with a remarkable 5.8mm profile — making it the thinnest Galaxy flagship ever produced. This device represents Samsung's commitment to engineering innovation, packing flagship-level components into an impossibly slim chassis. The titanium alloy frame provides exceptional rigidity despite the ultra-slim dimensions, and the device feels remarkably solid and premium in hand. At just 5.8mm thin and approximately 162 grams, the S25 Edge is noticeably lighter and thinner than virtually any other flagship smartphone.
Design & Build Quality
The Galaxy S25 Edge represents Samsung's most ambitious design statement in years. At just 5.8mm thin, it's thinner than most USB-C ports, yet feels remarkably solid thanks to the titanium alloy frame that provides exceptional structural rigidity. The glass front uses Corning's latest Gorilla Glass Armor with an anti-reflective coating that significantly reduces glare in outdoor conditions.
The weight distribution is impressive — at 162 grams, the phone feels light without being insubstantial. The flat-edge design language echoes the iPhone's industrial aesthetic but with Samsung's own refinements, including slightly rounded corners that make one-handed use more comfortable than you'd expect from a 6.6-inch device. The matte titanium finish resists fingerprints better than the glossy glass backs found on competing flagships.
Display Quality
The 6.6-inch Dynamic AMOLED 2X display delivers the vibrant colors and deep blacks Samsung is known for, with a 120Hz adaptive refresh rate that smoothly scales down to preserve battery life. The FHD+ resolution (1080 x 2340) is sharp enough for most use cases, though content creators may notice the lack of QHD+ compared to the S25 Ultra.
HDR10+ support ensures excellent streaming quality on Netflix and YouTube, while the 120Hz panel makes scrolling and animations feel buttery smooth. The anti-reflective Gorilla Glass Armor coating is a practical touch that makes the display more usable in direct sunlight — a genuine improvement over previous Galaxy flagships.
Performance & Software
Powered by the Snapdragon 8 Elite for Galaxy (custom-tuned), the S25 Edge delivers flagship-tier performance that handles everything from intensive gaming to AI-powered photo editing without breaking a sweat. The 3nm process ensures excellent power efficiency, which is critical given the phone's slim profile and necessarily smaller battery.
One UI 8.0 on Android 15 brings Samsung's latest AI features including Circle to Search, Live Translate, and Generative Edit — all running smoothly on the dedicated NPU. The 8GB or 12GB of LPDDR5X RAM ensures smooth multitasking, while UFS 4.0 storage provides rapid app load times and file transfers.
Camera System
The 50MP main camera with OIS captures detailed, well-exposed photos in good lighting conditions, with Samsung's image processing delivering the saturated, punchy look Galaxy users expect. The 12MP ultrawide offers a useful 120-degree field of view for landscapes and group shots, though it understandably can't match the main sensor in low-light performance.
The 12MP selfie camera handles video calls and social media content well, with decent skin tone accuracy. It's worth noting that the S25 Edge sacrifices the telephoto lens found on the S25 and S25 Ultra — a reasonable trade-off to maintain the ultra-slim form factor, but something to consider if optical zoom is important to you.
Battery & Charging
The 3,900mAh battery is the most obvious compromise of the ultra-slim design. While the Snapdragon 8 Elite's efficiency helps extend usage, heavy users may find themselves reaching for the charger before dinner. The 25W wired charging is adequate but not class-leading — Samsung's conservative approach to charging speeds prioritizes battery longevity over speed.
Wireless charging support is included, which is impressive given the 5.8mm thickness. In real-world use, the battery comfortably lasts a full day of moderate use, but power users who game extensively or shoot lots of 4K video will want to keep a charger handy.
