Samsung has never been a company to shy away from making a statement. From creating the “phablet” category with the original Note to popularizing curved displays, they have a rich history of showcasing their engineering prowess to set trends. The new Samsung Galaxy S25 Edge is a direct continuation of that legacy. It’s a device that looks to the future by calling back to a name from its past, delivering an experience that is as much about feel and philosophy as it is about performance. But in a world where battery is king, has Samsung made a compromise too far? We find out in our in-depth review.
The “Edge” Legacy Reimagined
Here at FoneArena, we’ve followed the evolution of Samsung’s “Edge” series from its very beginning. The name once signified a dramatic, 3D-curved screen. It was a futuristic concept that often came with practical trade-offs. However, the S25 Edge reimagines this legacy. The “Edge” here is not about a curved display; in fact, the screen is remarkably flat, much like the rest of the S25 lineup. This flatness is key to the phone’s excellent ergonomics, providing a secure, grippy feel that prevents accidental touches—a welcome evolution from its predecessors.
This new philosophy makes the S25 Edge a different kind of “Edge” device. It’s not pushing the boundaries of screen shape, but rather the boundaries of physics and material science. It’s a deliberate statement from Samsung, a showcase of their engineering muscle in an attempt to spark a new trend, just as they did with the Galaxy S8’s tall aspect ratio screen and the original Note. This phone isn’t just a product; it’s Samsung reminding the world that they can still lead the industry in design innovation.
Design and Build : A Triumph of Thin Engineering
The first thing you notice about the Galaxy S25 Edge isn’t its thinness, but how that thinness is deceptive. It looks elegant, but when you pick it up, the feeling is stunning. At just 5.8mm thick and weighing a mere 163g, it feels almost impossibly light. In daily use, you are constantly reminded that you’re holding a spectacularly thin and light device. The only real visual cue to this incredible slimness is the camera island, which protrudes slightly from the otherwise flat back.
Compared to its bigger brother, the S25+, which is already a lean device, the S25 Edge’s main advantage is its weight. The difference in mass is immediately noticeable and makes the Edge a more comfortable device to carry. Both phones feel secure in the hand thanks to their flat sides and non-slippery finish, but the Edge’s featherlight presence is its defining physical characteristic.
So, how did Samsung achieve this? It’s a combination of a redesigned, thinner-yet-broader vapor chamber (10% larger than the S25+), a new “hole structure” in the metal frame for better heat transfer, and the use of Gorilla Glass Ceramic 2, which has its own heat treatment properties. It’s a concerted engineering effort to build a slim phone without the usual performance compromises.
Display
The Galaxy S25 Edge sports a stunning 6.7-inch QHD+ Dynamic AMOLED 2X display with an adaptive 1-120Hz refresh rate. The colors are vibrant, the resolution is pin-sharp, and the brightness is excellent for outdoor visibility. As mentioned, the screen is flat, which provides a fantastic viewing experience without any color distortion at the edges.
Performance and Thermals: Defying the Odds
On paper, a Snapdragon 8 Elite processor in a 5.8mm chassis seems like a recipe for thermal throttling. However, Samsung’s engineering has truly shone through. In our experience with daily social media usage and multitasking, there were no discernible performance dips or stutters. The device gets warm under load, but no more so than any other flagship. While it’s not marketed as a gaming phone, performance during casual sessions remained stable, and there were no noticeable slowdowns in real-world use.
Battery Life: The Inevitable Compromise
Here we arrive at the elephant in the room: the 3,900mAh battery. On paper, this number is startlingly low for a flagship device in 2025. In reality, the battery life is not as bad as one might expect, but it is certainly not particularly impressive either.
For a moderate user, the phone will last a full day, delivering a typical screen-on time of 4 to 5 hours. However, for a heavy user, an evening charge is a definite necessity. The battery is, without a doubt, the S25 Edge’s biggest compromise. It’s a trade-off made in the name of its incredibly slim design. The phone ships with support for 25W fast charging, but no charger is included in the box.
Cameras
The S25 Edge features a dual-camera setup on the back, with a 200MP main camera and a 12MP ultrawide lens. This is a slight deviation from the S25+, which includes a dedicated telephoto lens. The main camera is excellent, capturing sharp, detailed photos with great color accuracy in various lighting conditions. The lack of a telephoto lens is a noticeable omission for zoom enthusiasts, but the high-resolution main sensor provides a decent 2x “optical quality” zoom that is sufficient for casual shots. The 12MP front camera also delivers crisp and clear selfies.
Conclusion: A Phone for the Discerning Few
The Samsung Galaxy S25 Edge is a beautifully engineered device that makes a bold statement. It successfully achieves its goal of being a stunningly thin and light phone without compromising on core performance or getting uncomfortably hot.
However, that achievement comes at the cost of battery endurance. This makes the S25 Edge a niche product, not intended for the mass market. The ideal customer is a busy executive or a fashion-conscious individual, who values the aesthetic experience and the carrying weight of their phone above all else. It’s for the user who wants a device that feels elegant, is effortless to carry, and gets out of their way.
If you are a power user or a mobile gamer, the S25+ is the more practical choice. But if you fall into that specific segment that values design, comfort, and engineering prowess over marathon battery life, the Samsung Galaxy S25 Edge is a unique and compelling proposition that you will likely enjoy.
Pricing and Availability
The Samsung Galaxy S25 Edge is available in Titanium Silver and Titanium Jetblack. It is priced at Rs. 1,09,999 for the 12GB + 256GB version and Rs. 1,21,999 for the 12GB + 512GB model. While these prices place it firmly in the ultra-premium category, it S25 Edge feels priced unrealistically.The standard Galaxy S25 and even the more advanced S25 Ultra offer better value at similar or slightly higher price points. Meanwhile, the Galaxy S24 series continues to be available at significantly lower prices while delivering comparable performance and battery efficiency. This makes the S25 Edge’s pricing difficult to justify, especially given its middle-of-the-pack positioning within the lineup.
