Is the Samsung Galaxy S25 Ultra the ultimate Android flagship of 2025? Samsung launched it in February during the Galaxy Unpacked event, positioning it as the top-tier model in the S25 lineup. With refined hardware, stronger AI smarts, and S Pen productivity in the mix, it’s clearly built to impress.
This review is for three groups of people:
Quick Take: The S25 Ultra is the most capable Android phone right now. It’s loaded with AI tricks, a stellar display, and powerful cameras. But it comes at a steep price.
Quick Overview: What’s the Galaxy S25 Ultra All About?
Think of the Galaxy S25 Ultra as Samsung’s all-in-one powerhouse: a smartphone that blends raw performance with clever AI features. It’s built for power users, creators, and anyone who wants the best Android experience money can buy.
Here’s the snapshot:
It’s big, bold, and built to last—clearly aiming to be the Android flagship of 2025. But does it truly outshine its rivals? Let’s dig deeper.
Unboxing: First Impressions Count
Unboxing the Galaxy S25 Ultra feels like unwrapping a piece of high-end tech without unnecessary frills. Samsung continues its eco-friendly approach, with sleek, minimal packaging that still manages to feel premium.
Inside the box, you’ll find:
That’s it—no charger brick in sight (a trend Samsung hasn’t reversed).
The phone itself makes a strong first impression. At 218g and 8.2mm thick, it strikes a balance between solid and refined. The titanium frame and Gorilla Armor 2 glass scream durability, while the matte Titanium Black finish keeps fingerprints at bay.
Power it on, and you’re greeted by a brilliant AMOLED display and Samsung’s polished One UI 7, which boots up in seconds. The experience feels seamless right from the start—exactly what you’d expect from a premium flagship.
Key Specs of Galaxy S25 Ultra (At a Glance)
Design & Build
Samsung gave the S25 Ultra a subtle makeover. Instead of sharp, squared edges, it now has rounded corners—closer to an iPhone silhouette but still very “Samsung.” At 218g, it’s lighter and slimmer than the S24 Ultra, making it easier to handle.
The titanium frame sandwiched by Gorilla Armor 2 glass feels rock-solid. It’s tougher (29% better drop resistance) and has an anti-reflective coating that cuts glare drastically. The new floating ring-style cameras look cleaner, and the phone comes in Titanium Black, Gray, Silverblue, and Whitesilver, with some online-only colors like Jadegreen.
Downsides? The sharp rails can feel a bit uncomfortable if you grip it tightly for long sessions.
Display
The 6.9-inch Dynamic AMOLED 2X is simply stunning. QHD+ resolution, HDR10+, and an adaptive 120Hz refresh rate make scrolling, gaming, and watching movies buttery smooth.
It’s one of the best displays you can get on any smartphone right now.
Performance
Powered by the Snapdragon 8 Elite for Galaxy, the S25 Ultra doesn’t break a sweat. Everyday tasks feel instant, and even heavy multitasking is effortless.
It does get a bit warm during extended gaming, but performance barely dips. For power users, this is as fast as Android gets.
Benchmark Scores: Samsung Galaxy S25 Ultra vs. Top Flagships in India (September 2025)
When it comes to raw performance, numbers speak louder than words. To keep this comparison relevant for Indian buyers, we’re only looking at phones currently available in India—not global models you can’t easily get. That means the OnePlus 13 and Oppo Find X8 Pro take the spotlight here, replacing niche devices like the ROG Phone 9 Pro or Red Magic 10S Pro+.
The benchmarks below are based on Geekbench 6, AnTuTu v10, and GPU compute tests (Vulkan & OpenCL).
Key Takeaway for Indian Buyers:
In short: the S25 Ultra isn’t the absolute top scorer, but it balances performance, cameras, display, and updates better than most rivals—making it a safer premium pick for long-term use.
Cameras
The quad-camera system is versatile and powerful:
Low-light performance is excellent, though it doesn’t always match Google’s Pixel in handling tricky shadows.
For video, you get:
The camera app is loaded with AI features like object removal, “Best Face” for group shots, and even a sketch-to-image tool.
Battery & Charging
The 5000mAh battery comfortably lasts a full day—even with heavy use. On lighter days, it can stretch to 1.5 days.
Not the fastest charging on the market, but dependable.
Software & Experience
Running Android 15 with One UI 7, the software feels clean, customizable, and smooth. The S Pen integration still makes it a productivity favorite.
Highlights:
