Samsung Galaxy S25 Edge review

Design

The design makes the S25 Edge seriously special. Samsung has taken a bold turn with this handset, delivering the thinnest Galaxy phone to date at just 5.8mm thick. This is more than just a design gimmick; combined with curved edges, the slim profile and ultralight weight means a truly premium in-hand experience. It’s noticeably lighter (which often means more comfortable to hold) than the flagship phones in the S25 lineup. For many users, this alone could seal the deal, making for a device with a truly user-friendly design.

The high-end titanium frame is durable, too. In line with the S25 series – and other manufacturers’ flagship phones – it has an IP68 rating that helps protect against water damage and dust, while Gorilla Glass Ceramic 2 coats the front screen to make scratches and scuffs a thing of the past. The colour options are stylish and minimal, ranging from Silver Titanium and Onyx Black to Sapphire Blue. Each finish feels polished and modern; in keeping with the super-light design, there’s no loud or flashy tones here.

Display

As you might expect from Samsung, the S25 Edge does not disappoint when it comes to display. The 6.8-inch Dynamic AMOLED display gives the impression of curving gently over the edges of the phone for a more immersive feel, while delivering vibrant colours, crisp contrasts and exceptional brightness.

The display also supports a super smooth 120Hz refresh rate, with peak brightness levels reaching up to a super-saturated 2,600 nits. Whether you're scrolling social media, gaming or catching up on shows, the screen feels fluid and ultra responsive. The display also features Vision Booster, which adjusts colours and contrast in real time depending on the lighting conditions you’re in. It makes the S25 Edge ideal for outdoor use, whether you’re reading in direct sunlight or using your phone to track a run.

Performance

The Galaxy S25 Edge runs on the Snapdragon 8 Elite for Galaxy; a custom chip built for speed and efficiency that’s also used to power the flagship S25 Ultra. Everything from gaming to photo editing feels fast and effortless, with little to no lag as you switch between screens. Under the hood, this handset includes up to 12GB of RAM and up to 512GB of storage, so multitasking is easy.

Samsung’s heat management system has also been improved with a larger vapour chamber, meaning less overheating and more sustained performance during long use sessions.

Software and AI

The Galaxy S25 Edge is equipped with Android 15 and Samsung’s One UI 7. It’s a clean, intuitive system that’s familiar to Galaxy users, packed with features but should still be easy to navigate for Samsung natives. While the S25 Edge doesn’t introduce any new AI features, the existing suite is made all the more impressive displayed on the beautifully thin screen.

Galaxy AI handles voice commands, real-time translation, and image editing with ease. And because it’s built into the core of the new and improved One UI, each feature feels subtle and seamless adding to your day, rather than impinging on it.

Live Translate remains one of the highlights here, letting you translate calls and messages in real time, perfect for travel or business. Circle to Search and AI Wallpaper generation are also part and parcel of the offering here, giving you access to handy tricks that quickly become part of your daily use.

Battery

The super-lightweight trade-off is only really noticeable in the S25 Edge’s battery. With its ultra-thin profile, the Galaxy S25 Edge houses a 3,900mAh battery, the smallest in the S25 series lineup. While this difference might sound stark – the S25 Ultra boasts a 5,000mAh battery – you'll be getting up to 24 hours of video playback compared to the S25 Ultra’s 31 hours. Heavy users might find themselves having to top up before they’d like to, but for the vast majority of us, the S25 Edge will be more than enough to see you through a daily commute and far more.

It’s a fair compromise given the phone’s incredibly slim build and for many, the comfort in hand will outweigh the need for a phone that doesn’t need to be charged overnight. Fast charging helps ease the blow further with 45W wired charging support, that should get you back to 50% in around 20 minutes.

Security

Maintaining your security on the Galaxy S25 Edge feels fast, simple and reliable. You’ll get Samsung’s ultrasonic under-display fingerprint scanner, along with Face Unlock to give you more confidence that you, and only you can access your data. Samsung Knox is a major plus, offering enhanced protection for your device, data and apps, and a free trial of Samsung Care+ is a nice touch too, using original parts to update your phone if needed.

As is to be expected from Samsung’s excellent support package, the S25 Edge doesn’t skimp on security and software updates, either. You’ll benefit from security update until May 2032.

Cameras

The camera system on the S25 Edge is smart and refined. It features a dual-lens setup, with a 200MP rear camera, a 12MP ultrawide lens and a 12MP selfie camera. There’s no telephoto lens, but the main sensor is excellent for everyday photography, capturing every detail with the clarity that we’ve come to expect from Samsung phone cameras.

Samsung’s innovative processing software also adds vibrancy without going overboard, and AI-assisted tools like Scene Optimiser and Nightography help capture sharp images even in tough lighting conditions. Design features take a bow here too, with the lightweight design offering more stability when taking photos, while the edge-to-edge design reduces any accidental lens smudging.

Summary

One of the most visually pleasing Galaxy phones to date, the S25 Edge is slim, light, and designed with premium materials. While the slightly smaller battery and lack of telephoto lens might be drawbacks for some, the comfort, visual appeal and sleek design make this a standout in the S25 series.
