Galaxy S24 Ultra • Unlocked vs Galaxy Z Flip4 • Unlocked

The Samsung Galaxy S24 Ultra, released in early 2024, and the Samsung Galaxy Z Flip4, launched in late 2022, represent distinct approaches to modern smartphone design. While the S24 Ultra offers a traditional, large-screen flagship experience with advanced capabilities, the Z Flip4 provides a compact, foldable form factor that prioritizes portability and a unique user interaction. Both devices operate on the Android platform, featuring Samsung's One UI, but cater to different user preferences through their core design and feature sets.

The expected lifespan and software support differ between these two devices, primarily due to their release timelines and Samsung's update policies.

• Software Longevity: The Galaxy S24 Ultra launched with Android 14 and is promised seven years of major OS updates and security patches, offering extended software support well into the future. The Galaxy Z Flip4, released with Android 12L, typically receives four years of OS updates and five years of security updates, meaning its software support will conclude sooner than the S24 Ultra's.
• 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. The Z Flip4, while featuring an aluminum frame and ultra-thin glass for its foldable display, also boasts an IPX8 water resistance rating. However, the foldable design introduces a mechanical hinge, which is a point of potential wear over time.
• Practical Lifespan: Users prioritizing the longest possible software support and a traditional, highly durable build will find the S24 Ultra better suited for extended use. Those who value the innovative foldable design and compact form factor of the Z Flip4 will still experience a quality device, though its software update cycle will end earlier.

Performance capabilities vary between the two devices, reflecting the advancements in mobile processing technology over their respective release periods and their intended use cases.

• Processing Power: The Galaxy S24 Ultra is equipped with a current-generation processor designed for demanding tasks, offering smooth performance for complex applications, intensive gaming, and advanced AI features. The Galaxy Z Flip4 utilizes a previous-generation processor that handles everyday applications and multitasking efficiently.
• Multitasking and Responsiveness: The S24 Ultra, typically featuring 12GB of RAM, provides ample capacity for seamless multitasking and quick app switching, maintaining high responsiveness even with numerous applications open. The Z Flip4, with 8GB of RAM, offers competent multitasking, though it may experience more noticeable performance throttling during prolonged heavy usage, such as extended gaming sessions, due to its compact design.
• Battery Behavior: The S24 Ultra houses a larger 5000 mAh battery, delivering excellent endurance that can last through a full day of heavy use and often beyond. The Z Flip4, with a 3700 mAh battery, offers improved battery life compared to its predecessor, generally providing sufficient power for a typical day of moderate use.

The display experience on these two Samsung smartphones presents a clear distinction in both form factor and visual characteristics.

• Display Technology and Clarity: The Galaxy S24 Ultra features a large 6.8-inch Dynamic AMOLED 2X display with a QHD+ resolution (1440x3120 pixels), providing exceptional sharpness and detail for all content. The Galaxy Z Flip4's main screen is a 6.7-inch Foldable Dynamic AMOLED 2X display with a Full HD+ resolution (1080x2640 pixels), offering vibrant colors and good clarity, though not as pixel-dense as the S24 Ultra.
• Brightness and Refresh Rate: Both devices offer a smooth viewing experience with a 120Hz adaptive refresh rate, which adjusts dynamically to content for fluid scrolling and responsiveness. The S24 Ultra boasts a significantly higher peak brightness of 2600 nits, ensuring excellent visibility even in bright outdoor conditions. The Z Flip4's main display reaches a peak brightness of 1200 nits, which is still bright for most environments.
• Unique Form Factor: The S24 Ultra provides a traditional, expansive flat display protected by Gorilla Glass Armor. The Z Flip4's defining feature is its foldable main display, which allows the device to become highly compact when closed. It also includes a 1.9-inch Super AMOLED cover screen for quick notifications and widgets without opening the phone.

The camera systems on the Galaxy S24 Ultra and Galaxy Z Flip4 are designed for different photographic priorities, with the S24 Ultra offering a more versatile and advanced setup.

• Rear Camera Capabilities: The S24 Ultra features a comprehensive quad-camera system, including a high-resolution 200 MP main sensor, a 12 MP ultrawide lens, a 10 MP telephoto lens with 3x optical zoom, and a 50 MP periscope telephoto lens with 5x optical zoom. This setup allows for exceptional detail, wide-angle shots, and significant optical zoom capabilities. The Z Flip4 has a dual-camera system with a 12 MP wide-angle main sensor and a 12 MP ultrawide lens, providing solid performance for everyday photos.
• Photography Performance: The S24 Ultra excels in various lighting conditions, producing detailed and vibrant images, with particular strengths in long-range zoom and low-light performance due to its larger sensors and advanced processing. The Z Flip4's main camera, with a larger sensor than its predecessor, offers improved low-light performance and good overall image quality, though it lacks a dedicated telephoto lens.
• Video and Unique Features: The S24 Ultra supports 8K video recording at 30 frames per second, along with advanced AI-powered editing features. Both devices offer 4K video recording. The Z Flip4 leverages its foldable design with 'Flex Mode,' allowing users to prop the phone at various angles for hands-free photography and video recording, enhancing creative possibilities.
