Design and Build: Premium Yet Familiar

At first glance, the S25 Ultra retains the iconic design language of the S-series, but with a few noticeable refinements:

Slimmer bezels create an almost edge-to-edge display.
Aerospace-grade titanium frame improves durability without adding weight.
Matte glass back resists fingerprints and offers a luxurious feel.

The phone is IP68-rated for water and dust resistance, making it reliable for everyday use. Available in four colors — Phantom Black, Titanium Silver, Emerald Green, and Sapphire Blue — the S25 Ultra strikes a perfect balance between elegance and functionality.

Display: Brighter, Smarter, and More Immersive

Samsung’s renowned 6.9-inch Dynamic AMOLED 3X display returns with:

Quad HD+ resolution (3200 x 1440)
Up to 2000 nits peak brightness
Adaptive 144Hz refresh rate for silky-smooth scrolling and gaming.

Thanks to improved AI-powered tone mapping, colors now appear more natural in bright sunlight. Watching HDR10+ content feels cinematic, while the ultra-sonic fingerprint sensor beneath the display is faster and more accurate.

Performance: Power Meets Intelligence

Under the hood, the Galaxy S25 Ultra packs the Qualcomm Snapdragon 8 Gen 4 (or Exynos 2500 in select regions), paired with up to 16GB of LPDDR5X RAM and 1TB of UFS 4.1 storage. Real-world performance is lightning-fast, whether you’re gaming, multitasking, or using advanced AI tools.

AI Boost Engine: Enhances app launch times and predicts your workflow.
Optimized power efficiency: Offers up to 30% better battery life compared to the S24 Ultra.
Cooling system upgrade: Keeps the phone cool even during prolonged gaming sessions.

Camera System: A Photography Powerhouse

Samsung takes mobile photography to new heights with its revamped quad-camera setup:

Main Sensor: 200MP f/1.6 with enhanced low-light performance.
Periscope Telephoto: 12MP with 10x optical zoom and AI-assisted stabilization.
Ultra-Wide: 50MP with improved edge sharpness.
AI Portrait Lens: Dedicated for professional-grade portraits and bokeh.

Video recording supports 8K at 60fps with superior stabilization. The new AI Camera Suite automatically suggests the best shooting mode and can remove unwanted elements in post-processing.

Battery Life and Charging

The 5,500mAh battery delivers all-day endurance even under heavy use. With 65W wired charging and 45W wireless charging, a 0-100% top-up takes just about 35 minutes. Reverse wireless charging is also available for accessories like Galaxy Buds.

Live Translate Pro: Real-time voice and text translation in over 50 languages.
