Introduction

Samsung continues to dominate the premium smartphone market with two standout models in 2025: the Samsung Galaxy Z Fold 7 vs Galaxy S25 Ultra . While both are flagships, they cater to very different audiences. The Fold 7 brings a futuristic foldable design with multitasking power, while the S25 Ultra sticks to the tried-and-true slab style but perfects it with high durability, stunning cameras, and exceptional battery life. Choosing between these two powerhouses can be tricky, so let’s dive deep into their features, pros, and drawbacks.

Design and Build Quality

The Galaxy Z Fold 7 is slimmer and lighter than its predecessors, featuring a refined hinge and thinner bezels. Its foldable AMOLED display unfolds into an immersive tablet-like screen, making it perfect for multitasking, gaming, or reading. However, foldables remain more delicate, with only limited dust and water resistance.

On the other hand, the Galaxy S25 Ultra is built like a tank. With a titanium frame, Gorilla Armor glass, and IP68 water resistance, it’s designed to handle everyday rough use. The design may not be as flashy as the Fold, but it’s dependable and rugged, which is crucial for users who prioritize durability.

Display Comparison

The Z Fold 7 boasts two displays: a 6.5-inch cover screen and a massive 8.0-inch foldable AMOLED main screen, both running at 120Hz refresh rate. This makes multitasking a breeze—opening multiple apps side by side feels natural.

The S25 Ultra features a single 6.9-inch QHD+ AMOLED panel with incredible brightness, sharpness, and smooth 120Hz performance. While it can’t transform into a tablet, it provides one of the best single-screen experiences you can get on a smartphone.

Performance and Software

Samsung Galaxy Z Fold 7 vs Galaxy S25 Ultra: The Ultimate Comparison

Both devices run on the latest Snapdragon 8 Elite for Galaxy chip, built on a 3nm process. Whether it’s gaming, video editing, or running multiple apps, both phones deliver lightning-fast performance. Samsung’s One UI 7 ensures smooth animations and includes AI-powered features such as real-time translation, AI camera enhancements, and smart multitasking tools.

The Fold 7 particularly benefits from multitasking features like split-screen and drag-and-drop across apps, while the S25 Ultra gets better optimization for the S Pen and camera functions.

Camera Capabilities

Samsung didn’t hold back on camera systems this year. The Galaxy Z Fold 7 comes with a 200MP primary camera, a 50MP ultrawide, and a 10MP telephoto lens with 3x zoom. Both its cover and internal screens feature front cameras, making video calls or selfies seamless.

The Galaxy S25 Ultra takes it up a notch with a quad-camera setup: a 200MP main sensor, 50MP ultrawide, and two telephoto lenses offering 3x and 5x zoom. This makes the Ultra unbeatable for zoom photography and versatility, especially for users who love capturing distant subjects.

Battery Life and Charging

Battery is one area where these two diverge significantly. The Fold 7 houses a 4400mAh battery, which is decent but must power two displays, meaning heavy users may need a midday top-up.

The S25 Ultra comes with a larger 5000mAh battery, optimized for efficiency. It comfortably lasts a full day even with heavy use. Both support fast charging, wireless charging, and reverse wireless charging, but the Ultra clearly wins for endurance.
