Samsung’s Galaxy S series has long set the standard for flagship smartphones. The Galaxy S24 Ultra impressed with its premium design, cutting‐edge camera, and powerful performance. Now, with the launch of the Galaxy S25 Ultra, Samsung promises subtle yet significant refinements. In this post, we dive into the key differences between the S24 Ultra and the S25 Ultra—from design tweaks and processing power to camera upgrades and battery efficiency—to help you decide if the upgrade makes sense for you.
Whether you’re eyeing the latest flagship technology or looking to save money with a renewed Samsung Galaxy S24 Ultra, this guide will help you decide which device suits your needs best.
Lighter & More Comfortable
The Samsung Galaxy S25 Ultra is noticeably lighter at 218 grams compared to the S24 Ultra’s 233 grams, making it more comfortable for daily use. Samsung has softened the previously boxy design by incorporating rounded edges and a premium titanium frame with Corning Gorilla Armor 2 glass—ensuring a modern, durable, and ergonomic build that stands out among Samsung flagship smartphones.
Bigger, Brighter, and More Immersive
Both the Galaxy S24 Ultra and Galaxy S25 Ultra feature a Dynamic AMOLED 2X display with HDR10+ support and a 120Hz refresh rate. The S25 Ultra, however, offers a slightly larger 6.9‑inch screen with slimmer bezels and an improved anti‑reflective coating for a truly immersive viewing experience—ideal for streaming, gaming, and mobile browsing. Enhanced audio tuning also ensures a richer multimedia experience on your Samsung Galaxy S flagship.
Next‑Generation Chipset for a Smooth Experience
Under the hood, the S25 Ultra is powered by the new Snapdragon 8 Elite for Galaxy (3nm process), delivering up to a 37% faster CPU and enhanced AI performance compared to the Snapdragon 8 Gen 3 (4nm process) in the S24 Ultra. Running Android 15 with Samsung One UI 7 and backed by seven years of updates, both devices offer a smooth, future‑proof experience—perfect for gamers and power users alike.
Sharper Shots and a New Ultra‑Wide Sensor
While both models feature a remarkable 200‑megapixel main sensor, the S25 Ultra upgrades the ultra‑wide camera from 12MP to an impressive 50MP sensor. This significant enhancement delivers exceptional detail and improved macro and wide‑angle photography—ideal for both professional photographers and smartphone camera enthusiasts.
Efficiency Through Innovation
Both devices sport a 5,000mAh battery with 45W wired charging, yet the S25 Ultra benefits from the efficiency gains of its new 3nm chipset and advanced thermal management. This means longer real‑world battery life for intensive tasks like gaming and video streaming—even when the capacity numbers remain identical.
