Choosing between Samsung’s flagship smartphones can feel overwhelming, especially when both devices pack premium features and cutting-edge technology. If you’re torn between the Galaxy S24 Ultra and the newer S25 Ultra, you’re not alone. Many people wonder whether the latest model justifies the upgrade or if the previous generation still holds its ground.
Both phones represent the pinnacle of Samsung’s smartphone engineering, but they cater to slightly different needs and preferences. Whether you’re a photography enthusiast, a power user, or someone who simply wants the best Android experience available, understanding the key differences will help you make the right choice for your lifestyle and budget.
Design and Build Quality: Subtle Yet Meaningful Changes
The first thing you’ll notice when holding both devices is how Samsung has refined the S25 Ultra’s design. While both phones maintain the premium titanium frame that users love, the S25 Ultra feels noticeably lighter in your hand at 7.69 ounces compared to the S24 Ultra’s 8.22 ounces. That difference might seem small on paper, but during extended use, it becomes quite apparent.
Samsung also made the newer model slightly thinner, reducing the thickness from 8.6mm to 8.2mm. The S25 Ultra measures 6.41 x 3.06 x 0.32 inches, making it more comfortable for one-handed use despite having a larger display. Both devices feature the same IP68 water and dust resistance, so you won’t have to worry about durability regardless of which model you choose.
The color options tell an interesting story about Samsung’s design philosophy. The S24 Ultra offered a vibrant palette including Titanium Violet, Yellow, Blue, Green, and Orange variants alongside the standard Black and Gray. The S25 Ultra takes a more refined approach with Titanium Silverblue, Black, Whitesilver, and Gray options. This shift suggests Samsung is targeting a more mature, professional audience with the newer device.
One significant upgrade that often goes unnoticed is the Corning Gorilla Glass Armor 2 protection on the S25 Ultra, replacing the original Gorilla Glass Armor on the S24 Ultra. This newer protection offers better scratch resistance and improved drop protection, which matters more than most people realize during daily use.
Display Technology: Bigger and Better Screen Experience
Both smartphones feature Samsung’s renowned Dynamic AMOLED displays with 120Hz refresh rates, but the S25 Ultra edges ahead with a slightly larger 6.9-inch screen compared to the S24 Ultra’s 6.8-inch display. This translates to a better screen-to-body ratio of 90.30% versus 89.12%, giving you more viewing area in nearly the same device footprint.
The resolution difference is minimal but worth noting. The S25 Ultra offers 3120×1440 pixels while the S24 Ultra delivers 3088×1440 pixels. Both maintain excellent pixel density around 500 PPI, ensuring crisp text and vibrant images. The brightness levels remain consistent at 2600 nits peak brightness, making both phones easily readable in direct sunlight.
What really matters for daily use is how these displays handle different lighting conditions and color accuracy. Both devices excel in outdoor visibility and offer excellent color reproduction for streaming videos, gaming, and productivity tasks. The larger screen on the S25 Ultra provides a slightly more immersive experience for media consumption and multitasking with the S Pen.
Performance: The Heart of the Matter
Here’s where the differences become substantial. The S25 Ultra features Samsung’s newest Snapdragon 8 Elite for Galaxy processor, built on a more efficient 3nm process compared to the S24 Ultra’s Snapdragon 8 Gen 3 on 4nm technology. This isn’t just about numbers – it translates to real-world performance improvements you’ll actually notice.
The new Oryon V2 Phoenix cores in the S25 Ultra deliver significantly higher clock speeds, with prime cores running at 4.47GHz compared to the S24 Ultra’s 3.39GHz maximum. This means faster app launches, smoother multitasking, and better performance in demanding games and productivity applications.
Gaming enthusiasts will appreciate the upgraded Adreno 830 GPU in the S25 Ultra versus the Adreno 750 in the S24 Ultra. This translates to better frame rates in graphics-intensive games and improved performance in augmented reality applications. Both phones handle current mobile games excellently, but the S25 Ultra provides more headroom for future gaming demands.
Memory configurations remain identical across both models, with 12GB of LPDDR5X RAM and storage options of 256GB, 512GB, or 1TB using UFS 4.0 technology. Neither device supports expandable storage, so choosing the right capacity upfront is crucial for your long-term satisfaction.
Camera System: Where Innovation Meets Reality
Photography represents one of the most significant upgrade areas between these two flagship devices. While both phones feature quad-camera systems with identical main sensors, the S25 Ultra introduces a game-changing improvement to the ultra-wide camera.
The main 200MP Samsung ISOCELL HP2 sensor remains the same across both models, delivering excellent image quality with optical image stabilization and advanced computational photography features. This consistency means you’ll get similar performance for standard photos, portraits, and low-light shooting.
The real difference lies in the ultra-wide camera upgrade. Samsung replaced the S24 Ultra’s 12MP Sony IMX564 ultra-wide sensor with a much more capable 50MP Samsung JN3 sensor in the S25 Ultra. This upgrade provides significantly better detail retention, improved low-light performance, and more natural color reproduction in wide-angle shots.
The telephoto cameras remain identical between both models, featuring a 10MP 3x optical zoom lens and a 50MP 5x periscope telephoto lens. This means you’ll get the same excellent zoom capabilities and portrait photography performance regardless of which device you choose.

These improvements might seem modest individually, but they add up to a significantly better daily experience, especially for heavy users.
The charging experience remains consistent between both models, with fast wired charging and convenient wireless charging options including reverse wireless charging for accessories like earbuds and smartwatches.
Software and Features: Android Evolution
The S25 Ultra ships with Android 15 while the S24 Ultra launched with Android 14, though both devices will receive seven years of OS updates from Samsung. The newer Android version brings subtle but meaningful improvements to privacy controls, notification management, and system efficiency.
Both phones include the S Pen stylus with identical functionality, making them equally capable for note-taking, digital art, and precise navigation. Samsung’s One UI interface remains consistent across both devices, ensuring a familiar user experience regardless of which model you choose.
The AI features and computational photography improvements in the S25 Ultra benefit from the more powerful processor, providing faster processing times for complex tasks and better real-time photo enhancement.
Connectivity and Future-Proofing
The S25 Ultra includes slightly newer connectivity standards, featuring Bluetooth 5.4 versus 5.3 in the S24 Ultra. While both support Wi-Fi 7 and identical 5G band coverage, the newer model offers better energy efficiency in wireless connections.
Both devices support the same range of cellular bands and data speeds, ensuring excellent network compatibility regardless of your carrier or travel destinations.
Pricing and Value Consideration

For budget-conscious buyers, the S24 Ultra represents excellent value, especially when available at discounted prices. The performance differences, while measurable, may not justify the price premium for casual users who primarily use their phones for communication, social media, and light gaming.
Power users and photography enthusiasts will likely find the S25 Ultra’s improvements worthwhile, particularly the enhanced ultra-wide camera and improved battery efficiency. The processing power upgrade also provides better long-term performance as apps and games become more demanding.
Making the Right Choice for You
Your decision between these two excellent smartphones should depend on your specific needs and budget constraints. The S24 Ultra remains a powerhouse device that handles everything most users throw at it, while offering potential savings that could be invested in accessories or other technology.
Choose the S25 Ultra if you’re a photography enthusiast who frequently uses ultra-wide shots, need the absolute best performance for gaming or productivity, or want the longest possible battery life. The newer processor and improved efficiency make it the better choice for users who plan to keep their phone for several years.
The S24 Ultra makes more sense for users who want flagship features at a potentially lower price point, don’t prioritize ultra-wide photography, or are satisfied with excellent rather than cutting-edge performance. It’s still an exceptional device that will serve most users beautifully for years to come.
Both phones represent Samsung’s commitment to premium smartphone experiences, and you’re unlikely to be disappointed with either choice. The decision ultimately comes down to whether the S25 Ultra’s improvements align with your specific needs and justify any price difference in your market.
