This is the top-of-the-line model in the S25 series, and it’s packing some serious heat in the form of AI, performance upgrades, and a sleek new design. If you’re wondering what makes this phone stand out, you’ve come to the right place. In this post, we’re diving deep into all the exciting details of the S25 Ultra, from its groundbreaking AI features to its upgraded camera and design changes. So, buckle up, and let’s get into it! You can get your hands on one starting February 7th, with pre-orders open now.
Galaxy AI: The S25 Ultra’s Core Strength
Alright, let’s talk AI because that’s where the real magic happens with the S25 Ultra. Samsung isn’t just throwing AI features at the wall to see what sticks; they’ve integrated it right into the operating system. The S25 Ultra is rocking One UI 7, Samsung’s next-gen mobile AI ecosystem, powered by Google’s Gemini 2.0 engine. This isn’t just about having a few cool tricks; it’s about changing how you interact with your phone.
Samsung is talking about multimodal AI agents that can understand text, speech, images, and videos, making your phone feel more intuitive than ever. They’re aiming for an AI-integrated OS that’s not just a tool, but an actual companion. This new direction is all about making your life easier and more efficient.
Cross-App Actions: Seamlessly Connecting Your Apps
- Ever wished your phone could just do things without you having to jump between apps? Well, Gemini makes it possible. Imagine asking your phone to find the schedule for your favorite team and add it to your calendar, or to find pet-friendly vegan restaurants nearby and text the list to a friend. The S25 Ultra can handle all that with a single voice command. It’s also super easy to switch between apps for quick follow-ups, like sharing a GIF or saving event details.
Bixby and Gemini: A Dual AI Approach
- Here’s where it gets a little interesting: Samsung is bringing back Bixby, but this time, it’s working alongside Gemini. Bixby is now enhanced with large language models and designed for handling phone functions, like changing settings, while Gemini tackles general web queries and more complex tasks. It might seem a bit confusing to have two AI assistants, but it allows each AI to specialize. For example, if you ask Gemini to change the device font settings, it might not be able to, but Bixby will.
Personalized AI: The S25 Ultra Learns You
- Now, let’s talk personalization. The S25 Ultra has a Personal Data Engine that analyzes your data right on the device to offer tailored experiences. This means your phone learns your habits and preferences, offering suggestions based on your routines. The Now Brief feature, for example, gives you a daily summary of the weather, your schedule, and even some routine suggestions. Plus, the Now Bar on the lock screen shows real-time info like sports scores and navigation without you having to unlock your phone.
AI-Powered Photo Editing and Creative Tools
- The S25 Ultra also has some pretty cool generative AI features, like photo editing, summarizing content, and writing suggestions. Drawing Assist lets you get creative with sketches, text, and image prompts. Audio Eraser is a nifty tool for getting rid of unwanted noise in your videos. And Generative Edit, which lets you remove objects from photos, is now faster and more accurate since it works locally on the device. Plus, AI Select will analyze what’s on your screen and provide recommendations, like making a GIF from a video.
Snapdragon 8 Elite for Galaxy: Unmatched Performance
Moving on to performance, the S25 Ultra is powered by the Snapdragon 8 Elite for Galaxy processor. This isn’t your everyday chip; it’s customized for Galaxy devices, and it’s seriously powerful. We’re talking a 40% boost in NPU, 37% in CPU, and 30% in GPU compared to the last generation. What does that mean for you? Faster speeds, smoother graphics, and an overall more responsive phone. Samsung and Qualcomm really teamed up to make this chip special.
Enhanced Cooling: Keeping it Cool Under Pressure
- With all that power, you need a good cooling system, right? Well, the S25 Ultra has an improved heat dissipation system with a 40% larger vapor chamber and a new thermal interface material. This helps keep the phone from overheating, especially during intense gaming sessions, and keeps your battery happy. The Ultra has the largest chamber of all the S25 models, making it the best for gaming.
Display Technology and ProScaler
- The display on the S25 Ultra is a beauty – a 6.9-inch AMOLED 2X QHD+ 120 Hz screen. Samsung also included something called ProScaler, which upscales lower-resolution images to match the screen. So even if you’re looking at an old photo or a lower-resolution image on Instagram, it will still look crisp and clear.
Gaming Performance
- For all you gamers out there, the Snapdragon 8 Elite for Galaxy is also equipped with the Vulkan Engine and improved Ray Tracing for smoother and more realistic mobile gaming.
A Slimmer, Sleeker, and More Durable Design
Now, let’s talk about looks. The S25 Ultra is sporting a new design with rounded edges and slimmer bezels. It’s the slimmest, lightest, and most durable Galaxy Ultra device ever, with a comfortable grip and sleek feel. Samsung has definitely refined the essence of Galaxy design with this one.
Corning Gorilla Armor 2: Enhanced Protection
- Durability is a big deal, and the S25 Ultra is using Corning Gorilla Armor 2, which has improved resistance to fractures. Samsung saw a 60 percent drop in screen repairs on the S24 over the S23 series, which could mean that the S25 is even more durable.
Sustainability: Eco-Friendly Materials
- Samsung is also stepping up its sustainability game. The S25 Ultra uses recycled materials, including recycled cobalt in the battery. They’re using recycled cobalt from older Galaxy devices and discarded batteries during the manufacturing process, giving those materials a new life.
Redefining Mobile Photography with Advanced Sensors
For the photo buffs, the S25 Ultra has an impressive camera setup. The 50MP ultrawide camera is a big upgrade from the previous 12MP sensor. You’re also getting a 200MP main camera, 50MP 5x telephoto, and 10MP 3x telephoto cameras. Samsung’s ProVisual Engine uses a spatial-temporal filter to make sure your photos are clear, even in low light.
Video Recording: Professional-Grade Features
- If you’re into videography, the S25 Ultra is packed with features. It now records in 10-bit HDR by default, giving you richer colors. There’s also Galaxy Log for those who want more control over color grading. The S25 Ultra also analyzes movement and time to reduce noise in your videos.
AI-Powered Editing Tools
- Editing your photos and videos is easier with the S25 Ultra. Audio Eraser can remove unwanted noise, like the sound of a crowd or wind. You also get Virtual Aperture for controlling depth-of-field. And the Portrait Studio feature lets you create personalized avatars, plus there are new analog filters for a film-like aesthetic.
Efficiency and Endurance: Battery and Charging Details
Battery life is always a concern, but the S25 Ultra has a 5000 mAh battery. Samsung claims you can watch videos for up to 31 hours on a full charge. When it comes to charging, the S25 Ultra supports 45W wired charging.
Qi2 Support: A Bit of a Catch
- Now, here’s the thing about wireless charging. The S25 Ultra is “Qi2 ready,” but it doesn’t have the built-in magnets for magnetic charging. This means you’ll need to use a case that supports the new standard to get the magnetic wireless charging experience.
S Pen Functionality: A Step Back or Strategic Choice?
The S Pen is still included with the S25 Ultra, which is great, but there’s a change: it no longer has Bluetooth capabilities. This means you won’t be able to use it for remote control features. Samsung says that it wasn’t a heavily used feature, so they removed it. Also, the “Smart Select” feature is now called “AI Select,” which uses multimodal LLMs, and according to a Samsung executive, is actually smart this time.
The Cost of the S25 Ultra and Where to Get It
Let’s talk about price. The S25 Ultra starts at $1299.99. You have storage options of 256GB, 512GB, and 1TB. It comes in colors such as Titanium Silverblue, Titanium Whitesilver, Titanium Gray, and Titanium Black, with exclusive colors like Titanium Pinkgold, Titanium Jetblack, and Titanium Jadegreen on Samsung.com.
The New Galaxy Club: An Upgrade Program?
- Samsung has a new Galaxy Club early upgrade program where you can pay a monthly fee ($8.33 for the S25 Ultra) and upgrade to the latest Galaxy device after 12 months. Samsung will pay the remaining installments or give you a trade-in credit. You’ll also get a year of Samsung Care+ with this plan.
Pre-Order Incentives
- If you pre-order, you can get some sweet deals, like Samsung Credit and discounts when you trade in an old phone.
One UI 7: Enhancing the User Experience with AI
The S25 Ultra runs on the new One UI 7, which is all about enhancing the user experience with AI. It’s designed to make your phone more intuitive and easy to use. Samsung is trying to make the Android experience feel more AI-driven and user-friendly. You also get updates like Auto Blocker, Maximum Restrictions settings, enhanced Theft Protection, and a new Knox Matrix dashboard.
A Focus on the User Experience
- Note that the user experience, as described in the sources, is more about features and less about how it feels to use the phone. Therefore, it will be important to test how the new AI features feel and if they are truly intuitive and helpful. Also, it is important to determine if they feel integrated into the operating system, or like separate features, when using the S25 Ultra.
Samsung vs. the Competition: A Look at the Market
The S25 Ultra is going head-to-head with some serious competition, like the iPhone 16 Pro Max and other flagship Android devices. Key differences include AI capabilities, hardware design, camera performance, and charging speeds. The S25 Ultra is stepping up its video game with features like Galaxy Log to match the “pro” features offered by Apple. However, the S25 Ultra is also $100 more than the iPhone 16 Pro Max.
Conclusion
The Samsung Galaxy S25 Ultra is packed with impressive features, with AI being the star of the show. From its innovative AI capabilities to its sleek design and enhanced camera, the S25 Ultra looks like a serious contender in the smartphone world. The question is whether the S25 Ultra represents a worthwhile upgrade for most users.
- Note that a final recommendation, based on real-world testing, is needed in the final blog post. It will be important to test out the real-world performance and battery life, see if the AI features actually make the phone more enjoyable to use, and if the loss of Bluetooth on the S Pen is actually a significant drawback.
