Galaxy S25 Ultra Vs Galaxy Z Fold5

The Samsung Galaxy S25 Ultra, released in February 2025, and the Samsung Galaxy Z Fold5, launched in August 2023, represent distinct approaches to premium smartphone design. While the S25 Ultra offers a traditional, high-performance slab experience, the Z Fold5 provides a unique foldable form factor that transforms from a standard smartphone into a larger tablet-like display. These devices cater to different user priorities, primarily differing in their physical design and the resulting user interaction.

The longevity of a smartphone is influenced by its physical resilience and the duration of software support it receives.

• Software Updates: The Galaxy S25 Ultra benefits from an extended software commitment, offering seven years of operating system upgrades and security updates, ensuring it remains current through Android 22. In contrast, the Galaxy Z Fold5 is eligible for four major Android OS upgrades and five years of security updates, with its final major OS upgrade expected to be Android 17. [11, 16, 20, 24, 34]
• Physical Durability: The Galaxy S25 Ultra features a robust design with a titanium frame and Gorilla Glass Armor 2 protection for its display, contributing to its overall resilience against drops and scratches. It also carries an IP68 rating for dust and water resistance. The Galaxy Z Fold5, while featuring a reinforced hinge and Gorilla Glass Victus 2 on its cover screen, has an inherently more complex foldable design. Its inner screen, while improved, requires more careful handling, and it holds an IPX8 water resistance rating, lacking official dust resistance. [17, 21, 27]
• Expected Lifespan: Users prioritizing the longest possible software support and a traditional, highly durable build may find the S25 Ultra more aligned with their needs. The Z Fold5, despite its advancements in foldable technology, presents a different set of durability considerations due to its moving parts and flexible display.

Both devices deliver robust performance, but their underlying hardware and how they handle demanding tasks differ due to their release timelines.

• Processing Power: The Galaxy S25 Ultra is equipped with a newer generation processor, allowing it to handle intensive applications, complex multitasking, and advanced gaming with enhanced speed and efficiency. The Galaxy Z Fold5, while still offering smooth performance for everyday use and multitasking, utilizes a previous generation processor. [1, 17, 21]
• Multitasking and Responsiveness: Both phones offer ample RAM, typically 12GB, to support fluid multitasking. The S25 Ultra's newer processor provides a slight edge in overall system responsiveness, particularly when running multiple demanding applications simultaneously. The Z Fold5's large internal display, however, offers a unique advantage for split-screen multitasking, allowing users to view and interact with several apps at once more comfortably. [1, 2, 17, 21]
• Battery Behavior: The Galaxy S25 Ultra houses a larger 5000 mAh battery, generally providing extended usage times for most users. The Galaxy Z Fold5 features a 4400 mAh battery, which, combined with its dual-screen setup, may require more frequent charging for heavy users, especially when utilizing the larger inner display extensively.

The display experience is a primary differentiator, with each device offering distinct advantages based on its form factor.

• Display Technology and Clarity: The Galaxy S25 Ultra features a single 6.9-inch Dynamic LTPO AMOLED 2X display with a high resolution, delivering sharp images and vibrant colors. The Galaxy Z Fold5 offers a dual-screen setup: a 6.2-inch Dynamic AMOLED cover display and a larger 7.6-inch foldable Dynamic LTPO AMOLED 2X inner display. The inner display provides an expansive canvas, though its resolution is distributed over a larger area. [1, 5, 8, 17, 21, 26]
• Brightness and Refresh Rate: Both devices offer a smooth 120Hz adaptive refresh rate for fluid scrolling and responsiveness. The S25 Ultra's display can reach a higher peak brightness, which can be beneficial for outdoor visibility in bright conditions. The Z Fold5's displays also offer good brightness, suitable for various environments. [6, 17]
• Viewing Experience: The S25 Ultra provides a premium, uninterrupted viewing experience on a single, large screen. The Z Fold5's foldable design allows for a compact phone experience when closed and an immersive, tablet-like experience when unfolded, ideal for media consumption and productivity. The presence of a visible crease on the Z Fold5's inner display is a characteristic of foldable technology. [15, 21]

The camera systems of these two devices cater to different photographic needs, with the S25 Ultra emphasizing advanced imaging capabilities.

• Rear Camera System: The Galaxy S25 Ultra boasts a more versatile quad-camera setup, including a high-resolution 200MP main sensor, a 50MP ultrawide lens, and two telephoto lenses (50MP with 5x optical zoom and 10MP with 3x optical zoom). This configuration allows for greater detail, flexibility in framing, and superior zoom capabilities. The Galaxy Z Fold5 features a triple-camera system with a 50MP main sensor, a 12MP ultrawide, and a 10MP telephoto lens (3x optical zoom), providing competent performance for everyday photography.

• Low-Light and Video Performance: The S25 Ultra's larger main sensor and advanced image processing generally result in better low-light performance and more detailed images across various conditions. Both devices are capable of high-quality video recording, but the S25 Ultra's hardware offers more advanced features and stability for videography. [15]
• Front Cameras and Audio: The S25 Ultra has a 12MP front camera. The Z Fold5 features a 10MP camera on its cover screen and a 4MP under-display camera on its main foldable screen, which is less discreet but allows for a full-screen experience. Both devices offer clear microphone quality for calls and good speaker output for media. [5, 8, 13, 21, 27]
