Introduction
Samsung’s Galaxy S Ultra series has long been a standard-bearer in smartphone innovation. With each new release, Samsung pushes the boundaries of design, performance, and user experience. If you’re considering upgrading to a new phone, you may be wondering which model offers the best value: the S23 Ultra, S24 Ultra, or the newly released S25 Ultra. In this S23 Ultra vs S24 Ultra vs S25 Ultra comparison, we break down the key differences in design, performance, camera systems, battery life, and more to help you make an informed decision.
Design and Build Quality
Galaxy S23 Ultra
The S23 Ultra was crafted with a robust design that featured a stainless-steel frame and Gorilla Glass Victus protection. While it was a sturdy and sleek phone, the design wasn’t a huge departure from previous Galaxy Ultra models. The 6.8-inch screen offered a large, immersive display, and the overall dimensions felt premium yet familiar.
Galaxy S24 Ultra
In the S24 Ultra, Samsung introduced some minor design refinements, keeping the core build quality from the S23 Ultra. The frame was still stainless steel, and the display size and overall design didn’t drastically change. The bezels were slightly reduced to provide a more modern look, but the design remained mostly unchanged.
Galaxy S25 Ultra
The S25 Ultra, however, marks a significant shift in the design department. With a titanium frame and Gorilla Glass Armor 2, the S25 Ultra is both lighter (218g) and thinner (8.2mm) compared to its predecessors. Samsung has also made the display larger, expanding it to 6.9 inches with even thinner bezels, resulting in a more immersive viewing experience. If you’re someone who values design and ergonomics, the S25 Ultra takes the crown in this S23 Ultra vs S24 Ultra vs S25 Ultra comparison.
Performance and Hardware
Galaxy S23 Ultra
When it comes to performance, the S23 Ultra was powered by the Snapdragon 8 Gen 2 processor, which delivered solid speed and performance for its time. With up to 12GB of RAM and storage options ranging from 256GB to 1TB, the S23 Ultra was a capable device, providing smooth multitasking and gameplay experiences.
Galaxy S24 Ultra
The S24 Ultra saw an upgrade with the Snapdragon 8 Gen 3 processor, providing improved speed and efficiency over its predecessor. The faster processor meant that the S24 Ultra could handle even more demanding apps and games, providing a noticeable performance bump compared to the S23 Ultra.
Galaxy S25 Ultra
The S25 Ultra takes the lead with the Snapdragon 8 Elite for Galaxy, a 3nm chipset that not only improves performance but also enhances energy efficiency. This makes the S25 Ultra the fastest and most energy-efficient of the three models. With 12GB of RAM and storage options of 256GB, 512GB, and 1TB, it’s clear that the S25 Ultra is the powerhouse in this S23 Ultra vs S24 Ultra vs S25 Ultra comparison.
Camera Systems
Galaxy S23 Ultra
The S23 Ultra featured an impressive 200MP wide-angle lens that allowed for stunning, high-resolution images. While the camera system was exceptional for its time, it lacked some of the more advanced software features that would appear in later models.

The S24 Ultra kept the same 200MP main sensor as the S23 Ultra, but with some key software enhancements, the camera system was improved in terms of image processing and color accuracy. The overall photo quality was still excellent, especially in good lighting conditions.
Galaxy S25 Ultra
The S25 Ultra continues with the 200MP main sensor but brings in a 50MP ultra-wide camera to enhance the low-light performance and offer a broader field of view. This addition allows for sharper, more detailed images in low light and provides greater versatility when capturing wide landscapes or group shots. For anyone prioritizing photography, the S25 Ultra stands out as the best choice in this S23 Ultra vs S24 Ultra vs S25 Ultra comparison.
