Samsung Galaxy S25 Ultra vs Samsung Galaxy S26 Ultra Review

Introduction

The Samsung Galaxy S26 Ultra is now the newer flagship in India, while the Galaxy S25 Ultra has shifted into a much more value-driven position because Samsung is currently showing a limited-period starting offer of ₹99,999 on its India buy page. That makes this comparison more important than ever for buyers who want the best Samsung flagship without overspending.

On paper, the S26 Ultra brings a thinner body, a newer Snapdragon chip, a built-in Privacy Display, faster 60W charging, and camera tuning focused on low-light video. The S25 Ultra still fights back with a more balanced value proposition, proven flagship hardware, and a much lower current entry price.

Key Highlights

• Galaxy S26 Ultra starts at ₹1,39,999 in India, while Galaxy S25 Ultra launched at ₹1,29,999 and is currently listed from ₹99,999 on Samsung.com.
• Galaxy S26 Ultra is thinner and lighter at 7.9mm and 214g; Galaxy S25 Ultra is 8.2mm and 218g.
• Both phones use a 6.9-inch class Dynamic AMOLED 2X display and a 5,000mAh battery, but the S26 Ultra adds Privacy Display and faster 60W charging.
• Galaxy S25 Ultra uses Snapdragon 8 Elite for Galaxy; Galaxy S26 Ultra moves to Snapdragon 8 Elite Gen 5 for Galaxy.
• Galaxy S26 Ultra improves low-light camera performance, but its 3x camera and macro flexibility are not clearly better than the S25 Ultra.

Details

The table below combines Samsung’s official India pages and launch announcements with 91mobiles’ structured spec sheets for side-by-side readability.

Design and Build Quality

The Galaxy S25 Ultra already feels premium with its titanium frame, built-in S Pen, Gorilla Armor 2 protection, IP68 rating, and a slightly more rounded body than older Ultra models. It still looks and feels like a proper no-compromise flagship in hand.

The Galaxy S26 Ultra refines that formula instead of changing it completely. Samsung adds a new glass camera island, trims the body down to 7.9mm, and cuts the weight to 214g. That makes it slimmer and easier to handle, even though it remains a big phone. Samsung also pushes privacy as a hardware feature this time with the built-in Privacy Display.

In daily use, the S26 Ultra feels slightly more polished. The S25 Ultra still feels more than premium enough, but the newer phone looks cleaner and sits better in the hand for long sessions.

Performance and Gaming

The Galaxy S25 Ultra runs on Snapdragon 8 Elite for Galaxy and Samsung says it improves CPU, GPU, and NPU performance while also using a larger vapor chamber and updated thermal material for smoother gaming. The phone remains fast for multitasking, video editing, and demanding titles, and long-term reviews still describe it as one of the most complete Android flagships.

The Galaxy S26 Ultra raises the ceiling with Snapdragon 8 Elite Gen 5 for Galaxy, a reported 39% NPU jump, 24% GPU boost, redesigned thermal management, and 21% better heat dissipation. In 91mobiles’ gaming data, the S26 Ultra posts much better overall benchmark numbers than the S25 Ultra and also shows lower heat buildup in the same comparison view. TechRadar’s long gaming session also found strong 60fps gameplay, though the phone still gets warm and can show small frame drops during extended stress.

Real-life usage score:
Galaxy S25 Ultra: 9.0/10
Galaxy S26 Ultra: 9.4/10

That gap is not huge in normal use. Apps, camera opening speed, multitasking, and UI smoothness are excellent on both. The S26 Ultra mainly pulls ahead for heavy gamers, AI-heavy workflows, and longer high-performance sessions.

Camera Review

The Galaxy S25 Ultra gives you a very versatile camera system: 200MP main, 50MP ultrawide, 50MP 5x telephoto, and 10MP 3x telephoto. Samsung’s own page highlights the sharper 50MP ultrawide and improved Nightography video, while Tom’s Guide praised its low-light results and sharper ultrawide, even if macro still was not the phone’s strongest area.

The Galaxy S26 Ultra keeps the same overall quad-camera idea but changes the tuning. Samsung upgrades the main camera to a faster f/1.4 lens, keeps the 50MP ultrawide and 50MP 5x camera, and continues with a 10MP 3x telephoto. Samsung and multiple reviews point to better low-light photos and video as the real headline upgrade.

In daylight, both phones deliver flagship-level detail, wide dynamic range, and strong zoom flexibility. The S25 Ultra remains excellent and still feels complete. The S26 Ultra pulls ahead more clearly after sunset, especially on the main camera and video side, thanks to the wider aperture and Samsung’s newer Nightography processing.

Low light is where the story changes. Digital Camera World found the S26 Ultra’s main and 5x cameras better suited to low light, but also noted that the 3x camera sensor is smaller this year and that close-focus / macro behavior is weaker than on the S25 Ultra. That means the S26 Ultra is not a clean win in every camera scenario.

Selfies stay similar on paper because both use a 12MP front camera, but Samsung says the S26 Ultra benefits from improved AI ISP for more natural skin tones and detail in mixed light. Video creators also get APV support, Log tools, and stronger pro-level controls on the S26 Ultra.

Camera samples verdict: The Galaxy S26 Ultra is better for night video, low-light main-camera shots, and newer pro video tools. The Galaxy S25 Ultra is still more balanced overall for buyers who want strong results across ultrawide, zoom, and close-up shooting without paying flagship-launch pricing.

Software and Features

The Galaxy S25 Ultra launched with Android 15 and Samsung promised seven generations of OS upgrades and seven years of security updates. It also brought One UI 7, Now Brief, Gemini integration, Audio Eraser, cross-app actions, and Samsung’s Personal Data Engine security layer.

The Galaxy S26 Ultra moves to Android 16 and continues Samsung’s seven-generation / seven-year update promise. The headline feature is Privacy Display, which can hide the full screen, selected apps, notifications, or PIN entry areas from side viewers. Samsung also adds stronger privacy features, upgraded thermal management, and more advanced camera/video tools.

One practical point matters: Tom’s Guide notes that the S26 Ultra does not ship at its highest QHD+ resolution out of the box. You need to switch that manually in Settings if you want the sharpest display.

Battery and Charging

Both phones carry a 5,000mAh battery and Samsung rates both for up to 31 hours of video playback. In day-to-day terms, both are safe one-day flagship phones.

The difference is charging and sustained efficiency. The S25 Ultra is still respectable, but the S26 Ultra now supports Super Fast Charging 3.0 at 60W and Samsung says it can reach up to 75% in around 30 minutes. 91mobiles’ comparison data also shows the S26 Ultra charging faster overall than the S25 Ultra.

Standby and heavy-use stability also look slightly better on the S26 Ultra because of the new chipset and cooling changes, though battery life itself is more of an evolution than a revolution. Samsung also confirms the S26 Ultra box does not include a charger.

Competitor Comparison Table

This table looks at the broader flagship space in India, not just Samsung vs Samsung. Pricing is based on current official or storefront listings available in India.

Best alternative: If the S26 Ultra feels too expensive, the best alternative is the Galaxy S25 Ultra because the price gap is now large while the day-to-day experience gap is still relatively small. For buyers outside Samsung’s ecosystem, the Pixel 10 Pro XL is the smarter Android alternative, while the iPhone 17 Pro Max is the clear iOS flagship rival.

First Sale / Offer Update

Samsung launched the S26 Ultra with strong pre-order benefits in India. Samsung Newsroom India listed benefits worth ₹20,000, including a storage upgrade on the 256GB model to 512GB during pre-order, plus bank / UPI cashback options on select variants. The current Samsung.com India buy page also shows ₹9,000 instant discount on all bank cards or up to ₹12,000 exchange bonus.

Samsung also rolled out Galaxy Forever for the S26 Ultra in India. That program lets buyers pay effectively half the cost first through 12-month financing, includes Samsung Care+ value, and gives a return / retain / upgrade route after one year.

For the S25 Ultra, the most important recent update is simpler: Samsung.com India is currently showing the phone at ₹99,999, which drastically changes its value position in the flagship market.

Launch offers tracker:

• S25 Ultra: watch for limited-period Samsung.com pricing and exchange value changes.
• S26 Ultra: bank discount, exchange bonus, and Galaxy Forever remain the key value levers.

Who Should Buy This Phone?

Choose the Galaxy S25 Ultra if you want a premium Samsung flagship for less money, already like Samsung’s ecosystem, want the S Pen, and care more about value than owning the newest model. It also makes more sense for buyers upgrading from much older phones like the S21 or S22 series.

Choose the Galaxy S26 Ultra if you are a power user, gamer, mobile creator, or frequent traveler who will actually use the better thermals, faster charging, improved low-light video, and Privacy Display. It is also the better fit for buyers who plan to keep one phone for years and want Samsung’s newest feature set from day one.

Ideal buyer profile:

• S25 Ultra: smart value buyer, Samsung loyalist, flagship hunter on a tighter budget.
• S26 Ultra: performance-first buyer, frequent creator, privacy-conscious power user, premium early adopter.

Final Verdict

The Galaxy S26 Ultra is the better phone. It is thinner, lighter, faster, cooler under load, more privacy-focused, and more capable in low-light camera work. On pure hardware and feature progression, it wins this comparison.

But the Galaxy S25 Ultra is the better deal right now. A current official Samsung.com starting price of ₹99,999 changes everything. At that level, it gives you a flagship Samsung experience, S Pen, top-tier display, strong cameras, and long software support for far less money than the S26 Ultra.

Should you buy or wait?

• Buy the Galaxy S25 Ultra now if price matters and you want maximum value.
• Buy the Galaxy S26 Ultra now if you want the latest Samsung flagship and will actually use its newer features.
• Wait only if you expect stronger festival-season discounts on the S26 Ultra or if your current phone is already performing well enough for another few months.
