Galaxy Z Flip4 • Unlocked vs Galaxy Z Fold6 • Unlocked

The Samsung Galaxy Z Flip4, released in August 2022, and the Samsung Galaxy Z Fold6, launched in July 2024, represent distinct approaches to foldable smartphone design. While both devices offer the innovative flexibility of a folding screen, they cater to different user preferences through their unique form factors and feature sets. The Z Flip4 emphasizes portability and a compact clamshell design, whereas the Z Fold6 prioritizes a larger, tablet-like experience when unfolded. Both run on the Android operating system, offering a consistent software experience with Samsung's One UI.

The expected practical lifespan of a smartphone is significantly influenced by its release timeline, software support, and physical durability. These two foldable devices offer different longevity prospects.

• Software Support: The Galaxy Z Flip4, released in August 2022, is eligible for four major Android OS updates and five years of security updates, with support extending until August 2027. In contrast, the newer Galaxy Z Fold6, launched in July 2024, benefits from Samsung's extended policy, promising seven years of Android OS upgrades and seven years of security updates. This means the Z Fold6 will receive software support for a significantly longer period, potentially until 2031.
• Repairability: Foldable phones generally present more complex repair challenges than traditional smartphones. The Galaxy Z Flip4 has a repairability score of 6.0 out of 10, with pull tabs for the battery and accessible battery cables being positive aspects, though screen replacement requires disassembling multiple components. The Galaxy Z Fold6 has a lower repairability score of 4.5 out of 10, primarily due to the extensive use of adhesive, the delicate process of screen removal, and the difficulty of accessing internal components.
• Physical Durability: Both devices feature IPX8 water resistance, meaning they can withstand submersion in water. However, neither has an official dust resistance rating, which is a common concern for foldable devices. The Z Fold6 incorporates an enhanced Armor Aluminum frame and a refined hinge design intended to improve longevity, though some durability tests have noted dust ingress into the hinge.

Performance in a smartphone is crucial for smooth daily operation, from launching applications to handling demanding tasks. Both the Galaxy Z Flip4 and Z Fold6 are equipped with capable hardware, but they offer different levels of processing power and memory configurations.

• Processing Power: The Galaxy Z Flip4 is powered by a processor from 2022, which handles everyday applications and multitasking efficiently. The Galaxy Z Fold6 features a more current-generation processor, optimized for Samsung's devices, providing enhanced speed and efficiency. This translates to faster app loading, smoother transitions, and more responsive performance, especially with intensive applications and gaming.
• Memory and Storage: The Galaxy Z Flip4 comes with 8GB of RAM, suitable for typical multitasking. The Galaxy Z Fold6 offers 12GB of RAM, providing more headroom for heavy multitasking and demanding applications. Both devices offer various internal storage options, typically ranging from 128GB to 512GB for the Z Flip4 and 256GB to 1TB for the Z Fold6, without expandable storage via microSD cards.
• Battery Behavior: The Galaxy Z Flip4 has a 3700 mAh battery, which generally provides a full day of moderate use. The Galaxy Z Fold6 is equipped with a 4400 mAh battery, designed to power its larger displays and more powerful components through a full day of use, with some users reporting it lasting up to 15 hours with varied usage. The Z Fold6's more efficient processor also contributes to its battery performance.

The display is a central feature for both foldable phones, offering unique experiences based on their form factors and underlying technology.

• Display Technology and Clarity: Both devices utilize Dynamic AMOLED 2X technology, known for vibrant colors and deep blacks. The Galaxy Z Flip4 features a 6.7-inch main foldable display with a resolution of 1080 x 2640 pixels and a 1.9-inch Super AMOLED cover display. The Galaxy Z Fold6 offers a larger 7.6-inch main foldable display with a higher resolution of 2160 x 1856 pixels and a 6.3-inch cover display with a resolution of 2376 x 968 pixels. The Z Fold6's larger and higher-resolution main screen provides a more expansive and detailed viewing experience.
• Brightness and Refresh Rate: Both main displays support a 120Hz adaptive refresh rate, ensuring smooth scrolling and responsive interactions. The Z Fold6's displays offer higher peak brightness levels, making them more visible in bright outdoor conditions. The Z Flip4's cover display is primarily for quick notifications and controls, while the Z Fold6's larger cover display is more functional for tasks without unfolding the device.
• Viewing Experience and Form Factor: The Z Flip4's clamshell design folds into a compact form, making it highly portable. When unfolded, it offers a traditional smartphone screen experience. The Z Fold6, with its book-like design, transforms from a standard smartphone form factor into a large tablet-like display, ideal for multitasking, media consumption, and productivity.

The camera systems on both the Galaxy Z Flip4 and Z Fold6 are designed to capture moments, but they differ in their capabilities and versatility.

• Rear Camera System: The Galaxy Z Flip4 features a dual-camera setup on the rear, consisting of a 12MP wide-angle lens and a 12MP ultra-wide lens. It includes optical image stabilization (OIS) on the wide lens and offers improved low-light performance compared to its predecessor. The Galaxy Z Fold6 boasts a more comprehensive triple-camera system, including a 50MP primary wide-angle lens with OIS, a 12MP ultra-wide lens, and a 10MP telephoto lens with 3x optical zoom and OIS. This telephoto lens provides greater flexibility for zooming in on subjects.
• Front Camera and Video: The Z Flip4 has a 10MP front-facing camera. Its foldable design allows users to utilize the higher-quality rear cameras for selfies, with a preview on the cover screen. The Z Fold6 features a 10MP front-facing camera on the cover display and a 4MP under-display camera on the main foldable screen, primarily for video calls. Both devices offer capable video recording, with the Z Fold6 supporting up to 8K resolution at 30fps.
• Photography Experience: User reviews indicate that the Z Flip4's camera performs well in everyday scenarios, with good color reproduction and HDR. The Z Fold6's camera system is considered more versatile, offering better detail and zoom capabilities, making it suitable for a wider range of photographic situations, including improved low-light performance thanks to its processing.
