Samsung Galaxy S25 Ultra — Living With Samsung's Best

Three months with the Galaxy S25 Ultra, and I have opinions. Some positive, some frustrated. Samsung's flagship is brilliant hardware wrapped in software that can't decide whether it wants to be helpful or annoying.

Design — Flatter, Sharper, Better

Samsung ditched the curved edges entirely. The S25 Ultra has flat sides with a titanium frame that looks and feels premium. It reminds me of a Note series phone, which makes sense given the built-in S Pen.

The corners are slightly more rounded than the S24 Ultra — less "stabbing your palm" during long usage sessions. It's a small change but a welcome one. At 218g, it's lighter than the iPhone 16 Pro Max, and I genuinely feel the difference.

The Titanium Silverblue colour I went with looks fantastic but picks up fingerprints on the back glass. Every. Single. Time.

Display

Samsung's displays remain the gold standard. The 6.9-inch QHD+ panel is absurdly vibrant. Watching HDR content on YouTube or Netflix looks better on this phone than on my living room TV, and I'm not exaggerating by much.

Peak brightness hits 2,600 nits. Outdoor readability in Delhi summer heat is perfect. The anti-reflective coating genuinely works — I can see my screen clearly even under harsh overhead lighting.

Vision Booster adjusts tone mapping based on ambient light, and it's one of those features you never think about until you use a phone without it.

Snapdragon 8 Elite Performance

The custom Snapdragon 8 Elite in the Galaxy variant is a beast. Benchmarks aside — and they're impressive if you care — what matters is real-world feel. Apps launch instantly. Multitasking between twelve apps in split-screen and pop-up windows is smooth. I've run Samsung DeX connected to my monitor with three apps in desktop mode without any lag.

Gaming performance is excellent. Genshin Impact at 60fps on highest settings holds steady, dipping only during the most chaotic sequences. The phone gets warm after 30 minutes but never uncomfortably hot.

What impresses me more is efficiency. Despite the power, battery life is noticeably better than the S24 Ultra. Samsung and Qualcomm clearly optimized the 3nm process well.

Galaxy AI — Hit or Miss

Samsung went all-in on AI features. Some are genuinely useful:

  • Circle to Search — Draw a circle around anything on screen to search. Actually saves time.
  • Live Translate — Real-time phone call translation. I tested it with a Japanese-speaking friend and it worked surprisingly well, with maybe a 1-second delay.
  • Note Assist — Summarizes S Pen notes and transcribes voice recordings. Accurate for English and Hindi.
Some are gimmicky:
  • Sketch to Image — Cool parlour trick, terrible results for anything serious.
  • AI-generated wallpapers — Generic and boring.
  • Chat Assist — Rewrites messages in different tones. I've never used this outside of testing.

Camera — The 200 MP Question

The 200 MP main sensor sounds like overkill, and in most scenarios, it is. The phone bins pixels down to 12 MP by default, and the results are excellent — sharp, well-exposed, with natural-looking colours. Samsung finally dialled back the oversaturation that plagued earlier Galaxy phones.

Night mode is outstanding. The S25 Ultra captures more light than any phone I've tested this year. Low-light street photography comes out clean with minimal noise. The AI-powered noise reduction is aggressive but doesn't smear details the way the S23 Ultra used to. Telephoto — The dual telephoto setup (3x and 5x) gives you flexibility. The 50 MP 5x sensor produces sharp, detailed crops at 10x digital zoom. Beyond 10x, quality drops off a cliff. Samsung's 100x Space Zoom remains a marketing gimmick — the results look like AI-generated paintings. Video — 8K recording at 30fps is technically possible, but 4K 60fps is where the practical sweet spot lives. Stabilisation is excellent. I recorded while walking through crowded Chandni Chowk, and the footage looked like I was using a gimbal.

S Pen

If you don't use the S Pen, you're essentially paying for dead weight. But if you do use it — taking notes in meetings, marking up PDFs, quick sketches — it's the one thing that separates the Ultra from every other flagship.

Latency is down to 2.8ms. Writing feels natural. Air Actions (gesture controls) are still gimmicky, and I've disabled them.

Battery Life

5,000 mAh gets me through a full day consistently. Heavy usage (lots of camera work, gaming, navigation) brings me to about 15% by 10 PM. Moderate usage? I've hit 30% at midnight.

45W charging fills the battery in about 55 minutes. Not class-leading, but respectable. Wireless charging at 15W is painfully slow — a full charge takes over two hours.

One UI 7 — The Good and the Bad

One UI 7 is Samsung's cleanest software to date. The animations are smoother, the settings are better organized, and there's less bloatware than previous versions.

But it's still Samsung. You'll still get notifications for Samsung apps you don't use. Galaxy Store still tries to exist alongside Play Store. And there are still duplicate apps — Samsung Internet alongside Chrome, Samsung Notes alongside Google Keep, Samsung Calendar alongside Google Calendar.

Seven years of OS updates and seven years of security patches is an excellent commitment though.

Pros and Cons

Pros:
  • Best Android display, period
  • Versatile quad-camera setup with excellent night mode
  • S Pen is unique and genuinely useful
  • Strong battery life with efficient Snapdragon 8 Elite
  • 7 years of updates
Cons:
  • One UI bloatware and duplicate apps persist
  • 15W wireless charging is dated
  • 200 MP and 100x zoom are more marketing than practical
  • Expensive, though cheaper than Apple's equivalent
  • Glass back is a fingerprint magnet

Verdict

The Galaxy S25 Ultra is the most complete Android phone money can buy. It does everything well — display, cameras, performance, battery. The S Pen gives it a productivity edge no competitor matches.

If Samsung could clean up its software the way Google does with Pixel, this would be a 9.5/10 phone. As it stands, the hardware excellence is slightly held back by software decisions that feel more about Samsung's ecosystem ambitions than user experience.

At ₹1,29,999, it's priced aggressively against the iPhone 16 Pro Max and delivers more features per rupee. Easy recommendation for Android users.

Rating: 8.5/10
