Samsung Galaxy S25 Ultra: Refinement at Its Absolute Peak

There is something almost philosophically interesting about the Samsung Galaxy S25 Ultra. It is, by most measurable standards, the finest Android smartphone Samsung has ever built. The display is extraordinary. The performance is borderline absurd. The camera system is reliably excellent. And yet — pick it up, and your first thought might be: this looks exactly like last year's phone. That tension between measurable excellence and a nagging sense of familiarity is the central story of the S25 Ultra, and it's worth sitting with before reaching for your credit card.

Design: Familiar, But Finally Right

Samsung has quietly done something significant with the S25 Ultra's design. Gone are the angular, almost aggressive lines of the S24 Ultra — replaced with a flatter frame, more rounded corners, and a silhouette that brings the phone closer in line with the rest of the Galaxy S25 family. The result is a phone that's marginally thinner, narrower, and lighter than its predecessor, while somehow feeling more premium in hand.

The front is protected by Gorilla Armor 2 — the industry's first scratch-resistant anti-reflective glass ceramic — and the frame is Grade 5 titanium, the same material Apple uses on its Pro iPhones. The bezels are the thinnest Samsung has ever put on a Galaxy S device. In short: this is a beautifully constructed object, even if it won't make you gasp in the way a foldable or a strikingly new design might.

Colour options remain conservative — Titanium Jetblack, Silverblue, and a handful of others — with the more expressive colours reserved for the cheaper S25 models. It's a curious choice for a $1,299 device, but it speaks to Samsung's presumption that Ultra buyers are a more serious, utilitarian crowd.

Display: The Best Screen on Any Smartphone

The 6.9-inch Dynamic AMOLED 2X panel running at 1440p resolution with a variable refresh rate of up to 120Hz is, without meaningful qualification, the finest display currently fitted to a smartphone. Brightness, colour accuracy, contrast, and sheer sharpness combine into something that makes content consumption feel genuinely different on this phone than on almost anything else.

Even with Gorilla Armor 2's anti-glare coating applied — which does slightly dull absolute peak brightness — the panel holds its own in direct sunlight better than virtually any competing device. Out of the box, Samsung has calibrated the display beautifully; most users will have no reason to touch the colour profile settings at all.

Performance: Violently, Effortlessly Fast

The Snapdragon 8 Elite for Galaxy — a boosted variant of Qualcomm's flagship chip, manufactured on the same ultra-efficient process node Apple uses for its A-series — is the most welcome upgrade in the entire S25 lineup. Apps open with zero perceptible delay. Animations are liquid-smooth. Gaming is rock-solid. And crucially, none of this comes at the cost of thermal comfort: the S25 Ultra manages sustained load without becoming noticeably warm in hand, a real improvement over previous generations.

Paired with 12GB of RAM and storage options from 256GB to 1TB, the S25 Ultra is genuinely desktop-class in its day-to-day snap. In side-by-side network tests with iPhones on the same carrier, the S25 Ultra consistently held onto weaker signals better and switched between Wi-Fi and cellular faster — a subtle but real-world quality of life improvement.

Camera: Software Is Doing the Heavy Lifting

The S25 Ultra's camera system is, on paper, nearly identical to last year's S24 Ultra — with one notable exception. The ultrawide lens has been upgraded from 12MP to a 50MP sensor with autofocus, and the difference is immediately visible in wide-angle shots: more detail, better edge sharpness, and improved low-light performance in environments where the ultrawide previously struggled.

The main camera remains a 200MP wide sensor, flanked by a 50MP 5x periscope telephoto and a 10MP 3x telephoto. Hardware upgrades beyond the ultrawide are essentially absent — but Samsung is leaning on the Snapdragon 8 Elite's improved image signal processor to drive gains across the board, and it shows. Low-light shots hold detail without dissolving into noise, autofocus is fast enough to handle genuinely chaotic subjects, and general exposure decisions are reliable in a way that flagships from a few years ago simply weren't.

Video quality is excellent, and the gap between Samsung and Apple in this department has narrowed to the point of irrelevance for most users. The one persistent criticism — that Samsung's processing can occasionally feel aggressive, with colours that bleed slightly in extreme zoom scenarios — remains valid, though shooting in RAW format sidesteps the issue entirely for serious photographers.

Galaxy AI: Genuinely Useful, When It Works

Samsung's Galaxy AI suite is the most polished implementation of AI features on any Android phone. Real-time call translation, transcript summarisation, generative photo editing (object removal and replacement), and the daily Now Brief — a digest of your calendar, weather, and travel updates — all function reliably and feel considered rather than bolted-on.

The integration of both Google's Gemini and Samsung's own AI layers gives the S25 Ultra a breadth of AI capability that no other Android manufacturer currently matches. Circle to Search remains one of the most genuinely useful smartphone features introduced in recent years. When Galaxy AI works — and it mostly does — it's brilliant. The caveat is that some features feel like a solution in search of a problem, and the sheer volume of AI toggles in settings can feel overwhelming for users who simply want a great phone rather than an AI showcase.

Battery: Finally, No Anxiety

The battery story of the S25 Ultra is one of its most underrated improvements. The capacity is unchanged at 5,000mAh, but Samsung's claim of 40% better power efficiency isn't marketing noise — it's something you feel. Waking up at 7am and going to bed well after midnight with charge to spare is now the consistent experience, rather than the optimistic one.

The unfortunate asterisk is wired charging, which remains capped at 45W. For a $1,299 phone in 2025, when mid-range competitors are routinely offering 65W and above, this is an increasingly hard position to defend. The phone does support Qi2 wireless charging, which is welcome — but the wired charging ceiling remains the S25 Ultra's most glaring practical shortcoming.

The S Pen: Still Here, But Diminished

The S Pen remains the S25 Ultra's most defining feature — the one thing that truly distinguishes it from every other large-screen Android flagship. For note-taking, sketching, and precision editing, it remains a genuinely useful tool that no competitor has replicated.

But Samsung has made a decision this generation that will frustrate power users: the S Pen has lost its Bluetooth connectivity. No more air actions. No more using the stylus as a remote camera shutter from across the room. For casual users, this is a non-issue. For the subset of people who relied on those features daily, it is a real and meaningful downgrade — and it's the kind of removal that makes you wonder what's next.

The Verdict

The Samsung Galaxy S25 Ultra is the Android equivalent of a perfectly tuned instrument. Nothing about it is broken. Everything about it is considered. The display is the best in the business, the performance is exceptional, battery anxiety is a thing of the past, and the camera system produces reliably excellent results in virtually any situation.

Its limitations are real but knowable: the charging speed is behind the market, the S Pen has been quietly stripped of its most distinctive feature, and the design — for all its polish — won't make anyone who saw last year's model do a double-take. For anyone upgrading from an S22 Ultra or older, this is one of the best phones ever made. For anyone coming from an S24 Ultra, the case for upgrading is substantially harder to make.
