Why buy Galaxy S25 Ultra?

Get unmatched speed, premium build and Samsung’s most advanced camera system. Ideal if you want pro-grade zoom, long-lasting battery and productivity tools like the built-in S Pen.

Three alternatives to consider:

Samsung Galaxy S25+ - Nearly flagship-level camera and display with a slightly smaller screen and lower price. Same AI features.
Samsung Galaxy S25 - Compact. Lighter. More affordable. Sacrifices zoom and S Pen, but still delivers AI upgrades and a strong battery.
Google Pixel 10 Pro XL - Smooth Android experience. Strong low-light performance. Software perks. Aluminium build. Slightly weaker on zoom.

Introducing the Galaxy S25 Ultra

Galaxy S25 Ultra sets a high bar. Titanium build. AI at its core. Pro‑grade 200MP camera and lightning‑fast Snapdragon 8 Elite chip.
A 6.9″ Dynamic AMOLED screen that dazzles. Long battery life. S Pen included.
Big on power. Big on polish. And hugely premium, without hidden fees.

Design

The Galaxy S25 Ultra is forged with a sleek titanium frame, a first in Samsung flagships.
Crafted for durability without weight. Rounded edges and premium finishes (Titanium Silverblue, Gray, Jetblack, Jadegreen) give a luxe feel.
It’s IP68-rated for water and dust resistance and covered front and back by Gorilla Glass Armor 2.
The built-in S Pen brings stylus control with One UI 7.
All packed into a slim, 218 g body that looks premium and feels resilient.

Camera

Four top-tier cameras deliver next-level flexibility. Jaw-dropping 200 MP wide lens. 50 MP ultra-wide sensor.
Dual telephoto lenses (5× periscope and 3× optical zoom). The ProVisual Engine and Galaxy AI enhance HDR, dynamic range and low-light shots.
Add in auto object-aware editing, noise reduction and spatial audio capture for video. Even with intense zoom levels, images stay sharp and detailed.
This is one of the most capable camera phones Samsung has ever made.

Video

Film like a pro. 4K@60fps or even 8K@30fps (depending on region) with Dolby Vision HDR.
Pro-level video gets extra polish with AI editing tools: stabilisation, spatial stereo sound and auto-enhancement.
True-to-life colours, sharp detail and seamless editing make capturing and sharing effortless.
Even without cinematic mode, the S25 Ultra delivers standout video quality. Especially with smart audio zoom and AI support.

Display

The 6.9″ Dynamic LTPO AMOLED 2X display is one of the brightest on any handset, peaking at 2,600 nits with 120 Hz adaptive refresh.
HDR10+ support means bold colour and deep contrast. Samsung's anti-reflective layer and Gorilla Glass Armor 2 reduce glare and protect against scratches.
Watching, gaming, scrolling — everything looks smooth and vibrant.

Processor

Inside, you’ll find the Snapdragon 8 Elite for Galaxy chip paired with 12 GB of RAM (up to 16 GB in some regions). Delivers blistering speed and top-tier AI performance.
Galaxy AI includes Now Brief, Audio Eraser, Writing Assistant and cross-app actions — right under One UI 7/8. Multitasking, app switching and games run flawlessly.
Predictive text, generative edits and a smooth interface all reinforce flagship experiences. Samsung guarantees 7 years of software updates, so this handset is future-proof.

Battery

With a 5,000 mAh battery, the Galaxy S25 Ultra delivers up to 31 hours of video playback — more than any S25 model.
When it’s time to charge, 45 W wired fast charging, Qi2 wireless charging and reverse wireless charging keep you powered and flexible.
Battery performance stays strong even under heavy use or video editing. No need to constantly hunt for a plug.

Colours and Storage Options

Available in standout hues like Titanium Silverblue, Gray, Whitesilver, and Jetblack. Plus exclusive tones like Jadegreen, Pinkgold, and others on Samsung.com.
Storage tiers start at 256 GB, jump to 512 GB, and go up to 1 TB (with region‑dependent options including 16 GB RAM).
With dual‑SIM + eSIM support and no microSD slot, this model is built for power users and creators who need space and speed.
