About the Samsung Galaxy S25 Ultra

The Samsung Galaxy S25 Ultra is Samsung's most capable smartphone, combining the raw power of the Snapdragon 8 Elite chipset with a refined titanium design and a camera system built for serious photography. Released in February 2025, it features a slightly larger 6.9-inch QHD+ Dynamic AMOLED display with slimmer bezels and rounded corners that make the phone more comfortable to hold than the angular S24 Ultra. The headline camera upgrade is a new 50MP ultrawide sensor that replaces the old 12MP module, delivering four times more detail in macro and wide-angle shots, while the proven 200MP main sensor and dual telephoto lenses remain. Performance is outstanding thanks to the custom Snapdragon 8 Elite for Galaxy chip, and Samsung's AI capabilities have matured with cross-app actions, smarter photo editing, and on-device processing. The 5,000mAh battery with 45W wired charging and Qi2 compatibility keeps you going through demanding days, and the S Pen remains tucked neatly into the body for note-taking and precision tasks. With seven years of updates, IP68 protection, and Gorilla Armor 2 glass, the S25 Ultra is built for users who want the absolute best Android phone available and plan to keep it for years.

Frequently Asked Questions

Is the Samsung Galaxy S25 Ultra worth buying?
Yes, the Samsung Galaxy S25 Ultra is the most complete Android phone available. It excels in performance, camera versatility, display quality, and software longevity. It is especially worthwhile if you value the S Pen, need a powerful camera with multiple zoom options, or want a phone that will remain fully supported for seven years.
How good is the Samsung Galaxy S25 Ultra camera?
The Samsung Galaxy S25 Ultra has one of the most versatile camera systems on any smartphone. It features a 200MP main sensor, a new 50MP ultrawide with dramatically improved detail, a 50MP 5x telephoto, and a 10MP 3x telephoto. It handles everything from macro photography to long-range zoom with excellent results, and LOG video support makes it suitable for professional video work.
Does the Samsung Galaxy S25 Ultra come with an S Pen?
Yes, the Samsung Galaxy S25 Ultra includes an S Pen that slots into a dedicated silo in the phone body. However, Samsung has removed Bluetooth functionality from the S Pen in this generation, which means remote shutter and gesture controls are no longer available. The S Pen still works fully for handwriting, note-taking, and on-screen precision tasks.
What is the battery life like on the Samsung Galaxy S25 Ultra?
The Samsung Galaxy S25 Ultra houses a 5,000mAh battery that delivers excellent all-day performance even under heavy use. It supports 45W wired fast charging, 15W wireless charging with Qi2 magnetic compatibility, and 4.5W reverse wireless charging. The efficient Snapdragon 8 Elite chipset helps extend battery life compared to the S24 Ultra.
Should I upgrade from the Samsung Galaxy S24 Ultra to the S25 Ultra?
For most S24 Ultra owners, the S25 Ultra is a modest refinement rather than a must-have upgrade. The main improvements are the faster Snapdragon 8 Elite chip, the upgraded 50MP ultrawide camera, rounded corners for better comfort, and enhanced AI features. If your S24 Ultra still meets your needs, waiting for the S26 Ultra may make more sense.
Is the Samsung Galaxy S25 Ultra waterproof?
The Samsung Galaxy S25 Ultra carries an IP68 rating, meaning it can withstand submersion in up to 1.5 metres of fresh water for 30 minutes and is fully dust-resistant. The front is protected by Gorilla Armor 2 glass for added durability against drops and scratches.
Should I get the Samsung Galaxy S25 Ultra or the Samsung Galaxy S25?
The S25 Ultra justifies its premium with a 200MP main camera, 50MP ultrawide, built-in S Pen, larger 6.9-inch QHD+ display, and a 5,000mAh battery with 45W charging. The standard S25 shares the same Snapdragon 8 Elite chip but in a lighter 162g body with a 50MP main camera, and it saves you £450 at £799 SIM-free vs £1,249. Choose the S25 if you want flagship performance without paying for the camera and S Pen extras. Compare Samsung Galaxy S25 deals.

Based on main-sensor size (1-inch / 1/1.3" beats 1/2.0"), telephoto reach (periscope > 5x > 3x optical), image processing tier (Apple Pro, Pixel Pro, Galaxy Ultra, Honor Magic Pro, Xiaomi Ultra), pro video features (ProRes, Apple Log, Dolby Vision), camera-partnership branding (Leica, Hasselblad, Zeiss) and OIS. Older flagships are de-rated since image processing pipelines have advanced significantly each generation. Megapixel count is deliberately downweighted — it correlates poorly with real-world camera quality.

Based on battery capacity (mAh) adjusted for platform efficiency calibrated against NotebookCheck, Tom's Guide, GSMArena and CNET reviewer tests. Apple A-series gets +45% (iOS process freezing + LTPO 1Hz + tuned panels make iPhone Pro Max outlast many 6500+ mAh Android phones in measured tests). Top Snapdragon / Dimensity flagships get +15%, budget chipsets are penalised −15% to −25% to reflect less efficient displays and looser background limits. Charging speed is excluded — see the separate Fast charging tag for that.
