Design & Build
The Samsung Galaxy S25 Ultra continues to push the envelope with a stunning blend of durability and sophistication. It features a glass front made from Corning Gorilla Armor 2, which not only offers enhanced scratch resistance but also reduces reflections due to its DX anti-reflective coating. The back panel is protected by Gorilla Glass Victus 2, giving the device a solid yet polished look and feel. Sandwiched between these is a Grade 5 titanium frame, adding strength without adding excessive weight.
With dimensions of 162.8 x 77.6 x 8.2 mm and a weight of 218g, the S25 Ultra feels substantial yet balanced in hand. The design retains Samsung’s signature squared-off edges and includes the integrated S Pen, making it a go-to device for power users, artists, and business professionals. Every detail, from button placement to camera alignment, feels intentional and premium.
It comes in a variety of elegant finishes, including Titanium Silver Blue, Jet Black, White Silver, and even Titanium Jade Green. The phone is also IP68-certified, ensuring dust-tight protection and water resistance up to 1.5 meters for 30 minutes.
Samsung has also fine-tuned the ergonomics. Despite the large display and metal frame, the slightly curved back and matte texture improve grip and handling. Whether held in one hand or laid flat on a desk, the phone radiates a sense of refined engineering.
Display
The Galaxy S25 Ultra features one of the most advanced smartphone displays available today. Its 6.9-inch Dynamic LTPO AMOLED 2X screen delivers a stunning 1440 x 3120 resolution, resulting in incredibly sharp visuals with an impressive ~498 PPI pixel density. With support for HDR10+, a 120Hz adaptive refresh rate, and a peak brightness of 2600 nits, the display excels in both bright outdoor settings and low-light conditions.
The LTPO (Low-Temperature Polycrystalline Oxide) technology allows the refresh rate to scale from 1Hz to 120Hz, improving battery life by dynamically adjusting to what you’re doing—whether it’s reading an article or playing a game. Paired with 480Hz PWM dimming, it ensures minimal eye strain during extended use. Samsung also includes a DX anti-reflective coating, significantly improving outdoor visibility.
Media consumption is immersive, thanks to the near bezel-less design and ~92.5% screen-to-body ratio. Blacks are deep, colors are vibrant, and motion is fluid. Whether you’re watching 4K videos, editing high-res photos, or gaming, the experience is top-tier.
Samsung’s focus on eye health is also commendable. With blue light reduction features and ultra-low flicker, the display is both beautiful and kind to your eyes, ensuring extended viewing comfort. This screen is arguably the best available on any smartphone as of 2025.

Performance
At the heart of the Galaxy S25 Ultra lies the Snapdragon 8 Elite chipset, fabricated on a 3nm process, offering improved efficiency and power. It features a high-performance octa-core CPU with two 4.47 GHz Oryon V2 Phoenix L cores and six 3.53 GHz Phoenix M cores, making it one of the fastest mobile CPUs available. Alongside it, the Adreno 830 GPU delivers desktop-level graphics performance.
In benchmarks, the phone crushes the competition: it scores 2,207,809 on AnTuTu, 9,846 on Geekbench, and 6,687 in 3DMark Wild Life Extreme. These numbers translate into real-world power—everything from 4K video editing to graphics-intensive gaming is buttery smooth. The phone remains cool under pressure, thanks to enhanced thermal management.
You also get blazing-fast storage with UFS 4.0, and memory options range from 12GB to 16GB of LPDDR5X RAM, with up to 1TB of internal storage. There’s no microSD card slot, but the built-in storage is more than enough for most users. App loading times are almost instant, and multitasking is seamless.
Whether you’re gaming, working, or editing large files, the S25 Ultra doesn’t stutter. The combination of fast CPU, powerful GPU, and generous RAM makes it a true flagship performer, future-proof for years.
Camera
Samsung has equipped the Galaxy S25 Ultra with a quad-camera system that rivals professional equipment. The 200MP main sensor captures stunning detail and dynamic range, using pixel binning for bright, noise-free images even in low light. It features multi-directional PDAF and OIS, ensuring sharpness in every shot.
You also get a 10MP 3x telephoto lens and a 50MP periscope lens with 5x optical zoom, both equipped with OIS and PDAF. Together, they deliver up to 100x Space Zoom, with much better clarity and stability than previous generations. Portraits and long-range shots are sharper and more natural.
The 50MP ultrawide sensor with 120° FOV captures more of the scene with minimal distortion. It also supports Super Steady video, perfect for action shots. Video recording supports up to 8K@30fps, 4K@120fps, with features like 10-bit HDR, HDR10+, gyro-EIS, and stereo sound recording for cinematic results.
Selfie performance is strong as well, with a 12MP front camera that supports dual pixel autofocus, HDR10+, and 4K@60fps video. Whether it’s photos, reels, or vlogs, the S25 Ultra is a content creator’s dream tool.

Battery & Charging
The Galaxy S25 Ultra impresses once again with its excellent battery life. It houses a 5,000mAh Li-Ion battery, which performs impressively with an active usage score of 14 hours and 49 minutes. Thanks to software optimization and the efficient 3nm chip, it handles a full day of use even with heavy tasks like gaming, 4K video streaming, or hotspot tethering.
Charging is fast and convenient. With 45W wired fast charging (PD3.0), the device can hit 65% in just 30 minutes. It also supports 15W wireless charging and is now Qi2 compatible, allowing seamless use with the latest magnetic wireless charging accessories. Additionally, it includes 4.5W reverse wireless charging to top up your Galaxy Buds or smartwatch.
Battery health has also improved over previous generations, thanks to AI battery management that optimizes charging speed and power drain based on your usage habits. This not only gives you better daily performance but also extends long-term battery longevity.
In real-world usage, the S25 Ultra easily lasts through a full day of work, gaming, content creation, and social media without needing a top-up—making it a reliable companion for power users and casual users alike.
Audio
Samsung has again delivered an excellent audio experience with the S25 Ultra. Though there’s no 3.5mm headphone jack, the phone compensates with stereo speakers tuned by AKG, offering rich and immersive sound. These speakers produce loud, well-balanced audio with strong bass and crisp highs.
The measured loudness is -24.6 LUFS, which is considered very good and ranks among the best on smartphones. Whether you’re watching movies, playing games, or listening to music, the stereo separation and clarity are impressive even at higher volumes.
For audiophiles, the S25 Ultra supports 32-bit/384kHz audio, delivering Hi-Res sound via USB-C headphones or wireless Bluetooth codecs like LDAC and aptX HD. It’s a treat for those who use high-end audio gear.
Even in speakerphone mode, voice calls are clear, thanks to noise cancellation and enhanced microphone performance. The audio system overall makes the S25 Ultra a great choice for media consumption and productivity.
Software
Out of the box, the Galaxy S25 Ultra runs on Android 15 with Samsung’s polished One UI 7. It’s clean, customizable, and filled with useful tools. Samsung promises 7 years of Android updates, setting a new industry standard for Android longevity and security.
The software is loaded with features like Samsung DeX and Wireless DeX, which allow you to connect your phone to a monitor and use it as a desktop PC. Combined with the powerful chipset and S Pen, it transforms into a true productivity device.
AI enhancements across One UI 7 add to the experience. From smart photo editing to personalized battery usage suggestions, the system adapts to how you use your phone. Features like App Continuity, split-screen multitasking, and Edge Panels enhance usability.
Despite the wealth of features, the UI remains smooth and responsive. Samsung has struck a great balance between functionality and simplicity, making the software feel powerful without being overwhelming.
