The Samsung Galaxy S25 Ultra was announced at the Galaxy Unpacked event alongside the S25 and S25 Plus on January 22, 2025. Similar to its predecessors, the Ultra model for the S25 lineup is designed for people looking for the best Samsung has to offer at a premium price. It’s a massive improvement and upgrade over the base model S25 in almost every facet, from the size to the performance and build.
The S25 Ultra also marks the start of Samsung’s ‘next era of mobile AI’ with an improved Galaxy AI, designed with personalisation and quality of life in mind. It’s also the only phone in the S25 series to support and come with a built-in S Pen.
If you’re considering Samsung’s Ultra model in its latest smartphone lineup, but you’re still on the fence, this article is for you. It covers everything you need to know about the S25 Ultra, how it differs from the rest of the S25 range, and how it compares to its predecessors.

The S25 Ultra features the best camera of any Samsung device to date, with its four-camera system and high megapixel count. The build quality is also premium, made from a strong titanium frame and reinforced Corning® Gorilla® Armor 2 display glass.
Artificial Intelligence Support
When it comes to the Galaxy S25 Ultra, users get the best of both worlds with Android artificial intelligence. The phone supports Samsung’s Galaxy AI features and deep integration with Google Gemini.
Along with supporting all the previous Galaxy AI features that were available on the S24 range, there are new features, including:
Cross-app Actions
This feature allows you to easily perform multiple actions at the same time using just your voice, even across multiple apps. For example, you can ask the device to find you a nearby restaurant, send the location to your friends, and open up the directions.
AI Select
AI Select is a new feature that is part of Galaxy AI and Samsung’s new One UI 7. It allows the user to search any content that is currently on their screen and provides contextually relevant suggestions.
Circle to Search
Circle to Search has received a massive update with the launch of the S25 Ultra. Now, it can recognise and identify more, like phone numbers, URLs, and sounds.
There are also two new artificial intelligence features available on the S25 Ultra focusing on personalisation: the Now Brief and Now Bar. The Now Brief is able to give you a quick summary when you start the day, like the weather, a Spotify playlist suggestion, and the latest news.
The feature is designed to grow ‘smarter’ over time as it collects more data for better summaries and recommendations. The Now Bar works similarly to the Now Brief. It provides personalised information on your lock screen using artificial intelligence.
Other Features
Beyond artificial intelligence support and the specifications, there are a few additional features that are supported on the S25 Ultra. The model still supports Samsung DeX, which allows users to connect the phone to a monitor and use it like a desktop.
The S25 Ultra is also the only model in its lineup that supports the S Pen, which is a special touchscreen stylus. The S Pen is customisable and can be used for navigation, taking notes, taking photos/videos remotely, and drawing.
How This Compares To Previous Samsung Galaxy Ultra Phones

When it comes to the S25 Ultra versus the S24 Ultra, the winner is clear. The S25 Ultra is a clear upgrade over its predecessor in almost every facet. To start with, Samsung managed to shave off 1.4mm from the width and 0.4mm from the thickness in the new model, making it lighter and thinner than the S24 Ultra.
The S25 Ultra also uses higher-quality materials for its construction. While the S24 Ultra uses the first version of Corning® Gorilla® Armor, the S25 Ultra uses the Corning® Gorilla® Armor 2. It also uses grade 5 titanium instead of grade 2, making the phone more durable.
While the S25 Ultra and the S24 Ultra both feature a 5000 mAh battery capacity, the S25 lasts longer. For example, the S25 Ultra lasted an extra hour when playing games, an extra hour when browsing the web, and an extra two hours watching videos.
The biggest change from the previous Galaxy Ultra model is the chipset. The S25 Ultra is powered by the Snapdragon 8 Elite for Galaxy (3nm), which is a major improvement over its predecessor’s Snapdragon 8 Gen 3 (4nm). The Snapdragon 8 Elite is a massive leap over the Snapdragon 8 Gen 3, providing a massive 45% boost in CPU power and 40% higher performance with the GPU. Qualcomm has also stated that the chipset is more efficient, so S25 Ultra users can expect better performance and longer battery life when gaming.
Is The Samsung Galaxy S25 Ultra Worth It?
If you’re looking for the best Samsung and the Android ecosystem has to offer, the S25 Ultra is worth considering. While it features a premium price tag, it offers cutting-edge tech, both with its chipset for entertainment and artificial intelligence.
When it comes to entertainment, there isn’t a phone better equipped than the S25 Ultra. The massive 6.9-inch screen is perfect for streaming, and the support for 120Hz is invaluable when it comes to gaming for a smooth experience.
Although all the other phones in the S25 range are also powered by the Snapdragon 8 Elite for Galaxy, tests reveal that the Ultra still performs the best. This could be due to the phone’s larger design, which allows for better heat management.
The S25 Ultra’s camera configuration is also the best Samsung has ever released and one of the best in the smartphone market. It’s finally placed Samsung neck-and-neck with its competitors, like the Pixel 9 Pro XL, which was previously heralded as the best Android device when it comes to photography.
At the end of the day, whether the S25 Ultra is worth it will depend on the user’s personal preferences. If photography and/or the display size is an important factor for you, it’s well worth shelling out the extra costs to get the Ultra over the other S25 models.
If you’re just looking for a phone that supports the latest Galaxy AI features and has the Snapdragon 8 Elite, the other S25 models would be sufficient. If the only thing holding you back from purchasing an S25 Ultra is the cost, there are options to save some money.
If you want to get the S25 Ultra cheaper, buying refurbished is a great, cost-effective solution. The money you save you can then spend on accessories or apps. Buying refurbished is also better for the environment—it helps cut down electronic waste and reduce greenhouse gas emissions.
