Galaxy S25 • Unlocked vs Galaxy Z Fold5 • Unlocked

The Samsung Galaxy S25, a traditional slab smartphone released in early 2025, and the Samsung Galaxy Z Fold5, a foldable device launched in mid-2023, represent distinct approaches to mobile technology. While both operate on the Android platform with Samsung's One UI, their fundamental designs offer different user experiences. The S25 focuses on a conventional, streamlined form factor, whereas the Z Fold5 provides a versatile, expansive screen that folds for portability.

When considering the long-term usability of these devices, their release timelines and inherent designs play a significant role in their practical lifespan.

• Release Timeline and Software Support: The Galaxy S25, being a 2025 release, benefits from a newer starting point for software updates, likely receiving Android version and security updates for a longer duration compared to the Galaxy Z Fold5, which was released in 2023. The Z Fold5 originally shipped with Android 13 and is currently on Android 16, while the S25 launched with Android 15.
• Physical Durability: The Galaxy S25 features an Armor Aluminum body and Gorilla Glass Victus 2 on both its front and rear, along with an IP68 rating for water and dust resistance, offering robust protection against environmental elements. The Galaxy Z Fold5, while also featuring an Armor Aluminum frame and Gorilla Glass Victus 2 on its cover screen and back, has an IPX8 water resistance rating but lacks official dust resistance. Its folding mechanism, though refined with a new hinge design for a flatter fold, introduces a unique point of potential wear, and its inner screen's plastic protector is more susceptible to scratches than glass.
• Expected Practical Lifespan: Users prioritizing maximum software longevity and comprehensive environmental protection may find the S25 more aligned with their needs. The Z Fold5, despite its robust hinge tested to withstand numerous folds, requires more careful handling due to its folding display and lack of dust ingress protection.

Both devices deliver high-level performance, but the newer Galaxy S25 integrates a more advanced processing unit, impacting overall responsiveness and efficiency.

• Processing Power: The Galaxy S25 is equipped with a current-generation processor, offering enhanced speeds for demanding applications, complex multitasking, and advanced AI features. The Galaxy Z Fold5, powered by a previous-generation flagship processor, still handles everyday tasks and most intensive applications smoothly, but the S25 provides a noticeable uplift in raw processing capability and efficiency.
• Multitasking and Responsiveness: Both devices come with 12GB of RAM, enabling efficient multitasking and smooth transitions between applications. The S25's newer processor contributes to a more responsive overall system, particularly in scenarios involving heavy computational loads or advanced on-device AI functions. Users of the Z Fold5 report quick app loading and no lag when running multiple apps simultaneously.
• Battery Behavior: The Galaxy S25 features a 4000mAh battery, designed to last a full day with mixed usage, offering up to 29 hours of video playback. The Galaxy Z Fold5 has a 4400mAh battery, which users report can last through an entire day with moderate usage, though heavy use of the larger inner display may necessitate more frequent charging.

The display experience is a primary differentiator, with the Galaxy S25 offering a premium traditional screen and the Z Fold5 providing a unique, expansive foldable display.

• Display Technology and Clarity: The Galaxy S25 features a 6.2-inch Dynamic LTPO AMOLED 2X display with a resolution of 2340x1080 pixels, delivering sharp visuals and vibrant colors. The Galaxy Z Fold5 offers a dual-screen setup: a 6.2-inch Dynamic AMOLED 2X cover screen and a 7.6-inch Dynamic AMOLED 2X main folding screen, both providing excellent clarity and color reproduction. The larger main screen of the Z Fold5, with its 2176x1812 resolution, offers an immersive viewing experience akin to a small tablet.
• Brightness and Refresh Rate: Both devices feature a 120Hz refresh rate for smooth scrolling and responsive interactions. The Galaxy S25 boasts a peak brightness of 2600 nits, ensuring excellent visibility even in bright outdoor conditions. The Z Fold5's displays reach a peak brightness of 1750 nits, which is also suitable for outdoor use.
• Viewing Experience: The S25 provides a consistent, high-quality viewing experience on a single, compact screen. The Z Fold5 offers the flexibility of a standard smartphone display on the cover and an expansive, tablet-like canvas when unfolded, ideal for media consumption, productivity, and split-screen multitasking.

Both smartphones offer capable camera systems, but the Galaxy S25, as a newer flagship, incorporates more recent advancements in imaging technology and software processing.

• Rear Camera Systems: The Galaxy S25 features a triple rear camera setup with a 50MP main sensor, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom, enhanced by optical image stabilization on the main and telephoto lenses. The Galaxy Z Fold5 also has a triple rear camera system, including a 50MP wide-angle lens, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom, with improvements driven by software algorithms and its processor.
• Photography Performance: The S25 benefits from newer image processing capabilities, leading to refined detail and color accuracy in various lighting conditions. The Z Fold5 delivers bright photos with rich color tones, even in low-light environments, thanks to software optimizations.
• Video Recording and Front Cameras: Both devices support video recording up to 8K resolution, with the S25 capable of 8K at 30fps and the Z Fold5 at 8K at 24fps. For selfies, the S25 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 screen, offering versatility for video calls and selfies.
