Galaxy S24 Ultra vs Galaxy Z Fold4

The Samsung Galaxy S24 Ultra, released in January 2024, represents a traditional flagship smartphone experience, while the Samsung Galaxy Z Fold4, launched in August 2022, offers a unique foldable design. The primary distinction lies in their form factors: the S24 Ultra is a conventional slab phone with an integrated stylus, whereas the Z Fold4 transforms from a compact smartphone into a larger, tablet-like device. Both devices operate on the Android platform, providing access to a vast ecosystem of applications and services.

These two devices offer different timelines for software support and exhibit distinct durability characteristics due to their designs.

• Software Longevity: The Galaxy S24 Ultra benefits from Samsung's extended update policy, promising seven years of operating system and security updates from its release. The Galaxy Z Fold4, being an earlier model, was initially promised four years of major Android OS updates and five years of security updates. This means the S24 Ultra will receive software support for a significantly longer period, potentially until Android 21.
• Physical Durability: The S24 Ultra features a robust titanium frame and Gorilla Glass Armor on its display, contributing to its overall resilience against drops and scratches. It also carries an IP68 rating for dust and water resistance. The Z Fold4, with its foldable design, has a different set of durability considerations. Its cover screen uses Gorilla Glass Victus+, and the inner foldable screen is protected by Ultra Thin Glass. It has an IPX8 water resistance rating, but no official dust resistance. User reports for the Z Fold4 have sometimes noted concerns regarding the inner screen protector peeling and hinge issues after extended use.
• Repairability: While specific repairability scores can vary, the S24 Ultra's traditional design generally makes it more straightforward to repair compared to the complex mechanics of a foldable device like the Z Fold4.

The performance capabilities of these two devices reflect their respective release timelines, with the newer S24 Ultra featuring more advanced internal components.

• Processing Power: The Galaxy S24 Ultra is equipped with a more recent-generation processor, which translates to faster app loading times, smoother transitions, and more efficient handling of demanding applications and games. Users report that the S24 Ultra handles intensive tasks and gaming with ease, maintaining smooth performance. The Galaxy Z Fold4, while still offering capable performance for everyday use and multitasking, features an earlier generation processor.
• Multitasking and Responsiveness: Both devices come with ample RAM, allowing for effective multitasking. The S24 Ultra's newer processor and faster storage contribute to a more consistently responsive experience, especially when switching between numerous applications or running several in split-screen mode. The Z Fold4's large inner display is well-suited for multitasking, though its older processor may show slight differences in speed compared to the S24 Ultra when handling very heavy workloads.
• Battery Behavior: The S24 Ultra houses a larger battery capacity, and users often report it can last through a full day of heavy use, with some experiencing up to two days on a single charge. The Z Fold4 has a smaller battery capacity, and while it generally provides sufficient power for a day of typical use, heavy users might find themselves charging more frequently.

The display experience is a key differentiator, with the S24 Ultra offering a single, high-quality flat screen and the Z Fold4 providing a versatile dual-screen foldable setup.

• Display Technology and Clarity: Both devices feature Dynamic AMOLED 2X displays, known for vibrant colors and deep blacks. The S24 Ultra has a 6.8-inch QHD+ display, offering exceptional sharpness and detail. The Z Fold4 features a 6.2-inch cover display and a larger 7.6-inch foldable inner display, both with adaptive refresh rates. The inner display of the Z Fold4 provides a tablet-like viewing area, which users find beneficial for media consumption and reading.
• Brightness and Refresh Rate: The S24 Ultra boasts a higher peak brightness, making it more visible in bright outdoor conditions. Both devices offer adaptive refresh rates up to 120Hz, ensuring smooth scrolling and fluid animations. The S24 Ultra's display also features an anti-reflective coating, which can improve viewing comfort in various lighting environments.
• Viewing Experience: The S24 Ultra provides a consistent, expansive viewing experience on its single, flat screen. The Z Fold4 offers the flexibility of a compact outer screen for quick tasks and a large inner screen for immersive content, though the crease on the foldable display is still noticeable to some users.

The camera systems on these devices cater to different priorities, with the S24 Ultra offering a more advanced and versatile setup.

• Camera System Capabilities: The Galaxy S24 Ultra features a highly capable quad-camera system, including a 200MP main sensor, a 12MP ultrawide lens, a 10MP telephoto lens with 3x optical zoom, and a 50MP telephoto lens with 5x optical zoom, which can achieve lossless 10x zoom. This setup provides extensive zoom capabilities and high-resolution imaging. The Galaxy Z Fold4 has a triple-camera system with a 50MP main sensor, a 12MP ultrawide lens, and a 10MP telephoto lens with 3x optical zoom.
• Photography Performance: The S24 Ultra generally delivers excellent photo and video quality across various conditions, including impressive low-light performance. Its advanced sensors and processing allow for detailed and vibrant images. The Z Fold4's camera system is competent for everyday photography, producing good results in well-lit conditions. However, it may not match the S24 Ultra's performance, particularly in challenging lighting or when utilizing zoom. Some users have noted that the Z Fold4's camera performance is adequate but not exceptional for its category.
• Video Recording and Audio: Both devices are capable of high-quality video recording. The S24 Ultra's more advanced sensors and processing can offer superior video stabilization and detail. For audio, both provide a good media consumption experience with decent speaker output, and microphone quality is generally clear for calls and recordings.
