Galaxy S25 Vs Galaxy Z Fold4

The Samsung Galaxy S25, released in early 2025, represents the latest iteration of Samsung's traditional flagship smartphone line, offering a conventional form factor with cutting-edge internal components. In contrast, the Samsung Galaxy Z Fold4, launched in August 2022, stands out with its innovative foldable design, transforming from a compact smartphone into a tablet-sized display. The primary distinction lies in their form factors, with the S25 providing a familiar, streamlined experience and the Z Fold4 offering a versatile, expansive screen for enhanced productivity and media consumption.

When considering the long-term usability of these devices, their release timelines and software support are key factors.

• Release Timeline: The Galaxy S25 was released in February 2025, making it a newer device compared to the Galaxy Z Fold4, which launched in August 2022. This difference in release dates impacts their respective software support cycles.
• Software Longevity: The Galaxy S25 is expected to receive up to seven years of Android operating system updates, extending its software lifespan significantly further into the future. The Galaxy Z Fold4, having been released earlier, is promised four major Android OS upgrades (up to Android 16) and five years of security updates, with support expected to continue until 2027.
• Physical Durability: The Galaxy S25 features an aluminum frame and is rated IP68 for dust and water resistance, offering robust protection against environmental elements. The Galaxy Z Fold4, while featuring an Armor Aluminum frame and Gorilla Glass Victus+ on its cover screen and back, has an IPX8 water resistance rating but no official dust resistance due to its folding mechanism. Its inner foldable display, made of Ultra-Thin Glass, is more susceptible to scratches than a traditional glass screen.

The performance capabilities of these two devices are largely influenced by their respective processors and RAM configurations, affecting how smoothly they handle daily tasks and demanding applications.

• Processing Power: The Galaxy S25 is equipped with a newer generation flagship processor, specifically a customized version of the Qualcomm Snapdragon 8 Elite for Galaxy. This provides enhanced speed and efficiency for running complex applications, high-fidelity games, and intensive multitasking. The Galaxy Z Fold4 utilizes the Qualcomm Snapdragon 8+ Gen 1 processor, which delivers smooth performance for most tasks, but represents an older generation of mobile silicon.
• Multitasking and Responsiveness: Both devices come with 12GB of RAM, allowing for efficient app switching and background process management. However, the S25's newer processor contributes to an overall snappier and more responsive user experience, particularly in scenarios requiring significant computational power.
• Battery Behavior: The Galaxy S25 houses a 4000 mAh battery, while the Galaxy Z Fold4 features a 4400 mAh battery. Despite the Z Fold4's larger capacity, its expansive main display can consume more power. Users of the Z Fold4 generally report that the device can last a full day with typical usage, sometimes extending into a second day with moderate use. The S25's newer, more efficient processor and potentially optimized software could lead to comparable or improved real-world battery endurance despite a slightly smaller capacity.

The display experience is a major differentiating factor, with the Galaxy S25 offering a single, high-quality screen and the Galaxy Z Fold4 providing a dual-screen, foldable setup.

• Display Technology and Clarity: The Galaxy S25 features a 6.2-inch Dynamic AMOLED 2X display with an FHD+ resolution (1080 x 2340 pixels), offering clear and vibrant visuals. The Galaxy Z Fold4 boasts two Dynamic AMOLED 2X displays: a 6.2-inch cover screen (2316 x 904 pixels) and a large 7.6-inch main foldable screen (2176 x 1812 pixels). The main screen of the Z Fold4 provides a tablet-like viewing area, which is beneficial for productivity and media.
• Brightness and Refresh Rate: Both devices offer adaptive refresh rates up to 120Hz for smooth scrolling and animations. The S25's display can reach a peak brightness of 2600 nits, ensuring good visibility in bright outdoor conditions. The Z Fold4's main display has a peak brightness of 1200 nits, which is still bright for most environments, and its adaptive refresh rate can scale down to 1Hz for power efficiency.
• Viewing Experience: The S25 provides a traditional, immersive full-screen experience. The Z Fold4's large inner display offers a unique, expansive canvas for multitasking, reading, and watching videos, though the crease in the middle of the foldable screen is still visible, particularly at certain angles.

Both smartphones offer capable camera systems, but their configurations and potential for user experience differ due to their form factors and generational advancements.

• Rear Camera Systems: The Galaxy S25 features a triple-camera setup with a 50MP main sensor, a 12MP ultrawide lens, and a 10MP telephoto lens with 3x optical zoom. The Galaxy Z Fold4 also has a triple-camera array, including a 50MP wide-angle camera, a 12MP ultra-wide camera, and a 10MP telephoto camera with 3x optical zoom. The Z Fold4's main camera sensor was an upgrade from its predecessor, offering improved light gathering capabilities.
• Front-Facing Cameras: The S25 includes a 12MP front camera for selfies and video calls. The Z Fold4 offers a 10MP camera on its cover display and a 4MP under-display camera on its main foldable screen. The under-display camera is designed to be less intrusive but offers lower resolution. A unique feature of the Z Fold4 is the ability to use its high-quality rear cameras for selfies by using the cover screen as a viewfinder.
• Photography and Video Quality: The S25 benefits from newer computational photography algorithms and potentially minor sensor refinements, which can enhance image processing and low-light performance. The Z Fold4's camera system was noted for its significant improvements over previous Fold models, delivering vibrant and detailed photos, particularly in good lighting. Both devices support high-resolution video recording, with the Z Fold4 capable of 8K at 24fps.
