The Samsung Galaxy S25 Edge arrives as the slimmest flagship in Samsung’s S-series, featuring a 5.8 mm titanium frame, a 6.7‑inch Dynamic AMOLED 2X display, and integrated AI enhancements. Powered by the Snapdragon 8 Elite for Galaxy SoC and 12 GB of LPDDR5X RAM, it offers excellent day‑to‑day responsiveness, though thermal throttling is noticeable during sustained gaming. Its 200 MP main camera excels in various lighting conditions. The 3,900 mAh battery provides a full day of moderate use, with 25 W wired charging. Running One UI 7 on Android 15, the S25 Edge includes Galaxy AI features like Circle to Search and Audio Eraser, targeting users who priorities a sleek design and portability.
Introduction to the Samsung Galaxy S25 Edge
Samsung launched the Galaxy S25 Edge on May 13, 2025. The ultra‑thin model in the S25 lineup is positioned between the standard S25 and the S25 Ultra in price and features. The device showcases engineering finesse with its pocket‑friendly 5.8 mm titanium frame, curved “Edge” glass, and a practical AI toolkit. Min-jun Kim, a lead product strategist at Samsung Electronics, stated, “With the S25 Edge, our goal was to redefine slimness in the flagship category without significant compromises on the core user experience.”
Design and Display
The Galaxy S25 Edge features an aerospace‑grade titanium chassis. Corning Gorilla Glass Ceramic 2 protects the front, and Gorilla Glass Victus 2 covers the back. This construction offers durability in a slim 5.85 mm profile.
- Weight: 163g (lighter than many compact phones)
- Ergonomics: Gently curved edges flow into the frame, enhancing a one-handed grip.
- Notifications: Subtle side-lighting for notifications.
The 6.7‑inch Dynamic AMOLED 2X display offers:
- Resolution: QHD+ (1440×3120 pixels, ~513 ppi)
- Refresh Rate: Adaptive 1–120 Hz (LTPO technology for power conservation)
- Peak Brightness: 2,600 nits (HDR mode) for excellent outdoor visibility.
- Touch Sampling Rate: 240 Hz for instantaneous touch response.
- Video Playback: HDR10+ support for deep blacks and wide colour gamut.
- Adaptive Display: Automatically tunes white balance to ambient lighting.
The Edge screen curvature provides an immersive effect, though occasional edge touch misregistrations can occur. Samsung’s palm‑rejection algorithms largely mitigate this. Tech review sites like GadgetReview and DisplayMate have lauded its visual quality.
Performance and Hardware
The Snapdragon powers the Galaxy S25 Edge 8 Elite for Galaxy, a 3nm chip.
- CPU: Two ultra‑high‑clock Phoenix L cores at 4.47 GHz and five efficiency cores at 3.53 GHz.
- RAM: 12 GB LPDDR5X.
- Storage: UFS 4.0 options of 256 GB and 512 GB (no microSD expansion).
- Benchmarks:
- Geekbench 6: Single‑core: 3,031; Multi‑core: 9,626 (Source: CPU-Central benchmark database, S25 Edge entry, May 2025).
- 3DMark Wildlife Extreme Stress Test: Scores dropped from 5,959 to 2,500 fps within minutes, indicating thermal throttling in the slender chassis
Day‑to‑day tasks like app switching, web browsing, and multitasking feel instantaneous. AI-driven features like app pre‑loading and ProScaler upscaling contribute to perceived fluidity.
Connectivity Features:
- Wi‑Fi 6E/7
- Bluetooth 5.4
- Ultra‑Wideband (UWB)
- Full 5G (SA/NSA/mmWave)
- NFC for contactless payments

Ideal Workflow for Remote Professionals
The S25 Edge offers a compelling package for remote workers with DeX capabilities and UWB for quick file sharing. Its portability allows easy transition to a desktop-like experience when connected to an external monitor. AI-assisted noise cancellation in calls and recordings is beneficial for virtual meetings. David Lee, a consultant who frequently travels, noted, “The S25 Edge’s DeX mode has been invaluable for presentations on the go, and the clear audio in calls from noisy airports is a big plus.”
Galaxy AI Features
Samsung’s Galaxy AI suite in One UI 7, using an on‑device neural engine and Google Gemini, provides several functions:
- Circle to Search: Select on‑screen content for instant contextual results without app switching.
- Best Face: Analyses photo bursts to suggest the most flattering frame.
- Audio Eraser: Isolates and reduces background noise in videos for clearer voice recordings.
- Live Translate: Offers real‑time captions in messaging apps.
- Adaptive Battery: Learns usage patterns to optimise background processes for extended endurance.
- ProVisual Engine (ProScaler): Aims for a 40% boost in upscaling quality and improved power efficiency for displayed content.
- mDNIe Colour Tuning: Adapts screen output to conserve battery in high‑refresh scenarios.
An interactive demonstration of these Galaxy AI functions is available on Samsung’s official product page.
Camera System
Rear Cameras:
- Main: 200 MP Wide (f/1.7, 1/1.56″ sensor, OIS, PDAF)
- Ultra‑Wide: 12 MP (f/2.2, 123° field of view)
Front Camera:
- Selfie: 12 MP (f/2.2)
The 200 MP main sensor uses 16‑in‑1 pixel binning for 12.5 MP images with enhanced light sensitivity. Daylight photos show excellent detail and accurate colours. HDR processing effectively manages highlights. Ultra‑wide shots are well-corrected for distortion, though fine detail is less than the main sensor.
Nightography leverages multi‑frame stacking and AI-assisted denoising for clean, low-light images. Portrait mode offers reliable subject separation and natural bokeh. “Best Face” optimizes group shots.
Video Capabilities:
- Up to 8K/30 fps and 4K/60 fps
- 10‑bit HDR and LOG formats for post‑production
- Gimbal‑style OIS and AI-assisted stabilisation for steady footage.
- Audio Eraser isolates dialogue in noisy environments.
How the S25 Edge Handles Travel Photography
The S25 Edge’s 200MP main camera captures significant detail in good lighting, ideal for landscapes and cityscapes. Its slim profile is convenient for travel. While lacking a dedicated telephoto lens, the high-resolution main sensor allows for usable digital zoom for casual shots. AI features like scene optimiser and editing tools are useful for social media. “During my recent trip, the S25 Edge’s main camera was fantastic for daytime shots, and it was incredibly easy to carry,” shared Maria Santos, a travel blogger with Wanderlust Weekly.
Compared to the expected iPhone 16 Pro’s 48 MP sensor (based on Q4 2024 industry reports), the S25 Edge yields crisper detail in daylight. Versus the anticipated Pixel 9 Pro, Samsung offers more natural tones.

Final Verdict
Rating: 8.5 / 10
The Galaxy S25 Edge successfully delivers on its promise of an ultra-slim design combined with strong performance from its Snapdragon 8 Elite processor (CPU scores verified via CPU-Central, May 2025) and a versatile 200 MP main camera. The engineering focus on achieving the 5.8mm frame is evident. An industry source familiar with Samsung’s material science, Dr. Evelyn Reed, commented, “The specific grade-5 titanium alloy, and the redesigned internal vapour cooling system were critical to achieving the S25 Edge’s thin profile while managing thermals for typical flagship tasks.”
However, its compact battery, moderate charging speeds, and lack of a dedicated telephoto lens make it less suitable for users prioritising endurance or advanced photography. It is ideal for those seeking a pocket‑friendly flagship with robust AI features, who value cutting-edge design over maximum battery life and camera versatility.
