Galaxy Z Fold4 Vs Galaxy Z Fold6

The Samsung Galaxy Z Fold4, released in August 2022, and the Samsung Galaxy Z Fold6, launched in July 2024, represent two generations of Samsung's foldable smartphone line. While both devices offer a unique folding form factor, the Z Fold6 introduces refinements in design, an updated processor, and extended software support. Both operate on the Android platform, providing a versatile user experience that adapts from a compact smartphone to a larger tablet-like display.

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

• Release and Software Support: The Galaxy Z Fold4, launched in August 2022, was promised four major Android OS updates, extending its support up to Android 16, and five years of security updates, concluding around August 2027. In contrast, the newer Galaxy Z Fold6, released in July 2024, benefits from Samsung's updated policy, offering seven years of both OS and security updates, providing a significantly longer period of official software support.
• Build and Practical Lifespan: Both models feature robust construction with Armor Aluminum frames and water resistance (IPX8 for the Fold4, IP48 for the Fold6). The Z Fold6 introduces an enhanced Armor Aluminum frame and Gorilla Glass Victus 2 on its cover screen, potentially offering improved resilience. Users can expect a practical lifespan influenced by these physical attributes and the duration of software updates, with the Z Fold6 offering a longer window for receiving the latest features and security patches.

The performance capabilities of the Galaxy Z Fold4 and Z Fold6 reflect the advancements in mobile processing technology over their respective release cycles.

• Processing Power: The Galaxy Z Fold4 is equipped with a processor that handles demanding applications and multitasking smoothly, providing a responsive experience for everyday use and gaming. The Galaxy Z Fold6, featuring a newer generation processor, offers enhanced speed and efficiency, resulting in quicker app loading times, more fluid transitions, and improved performance in graphically intensive games and complex productivity tasks.
• Multitasking and Storage: Both devices come with 12GB of RAM, enabling efficient multitasking across multiple applications on their large internal displays. Storage options for both models range from 256GB to 1TB, providing ample space for applications, media, and documents. The Z Fold6's newer processor also contributes to better power management, which can translate to more consistent performance during extended use.
• Battery Behavior: The Galaxy Z Fold4 has a 4400 mAh battery, providing around 11-12 hours of video playback on its main screen, with some users reporting up to 9 hours and 24 minutes of screen-on time under specific conditions. The Galaxy Z Fold6 maintains a 4400 mAh battery capacity. However, its more efficient processor and a larger vapor chamber are designed to optimize power consumption and thermal management, potentially leading to comparable or slightly improved real-world battery endurance despite the same capacity.

The display experience is central to foldable smartphones, and both the Galaxy Z Fold4 and Z Fold6 offer expansive, high-quality screens with some notable differences.

• Display Technology and Clarity: Both devices feature Dynamic AMOLED 2X technology on their main and cover displays, delivering vibrant colors and deep blacks. The Galaxy Z Fold4's main display measures 7.6 inches with a resolution of 1812 x 2176 pixels, while its cover screen is 6.2 inches at 904 x 2316 pixels. The Galaxy Z Fold6 retains a 7.6-inch main display but with a slightly different 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 cover screen is also notably wider, offering a more traditional smartphone aspect ratio when folded.
• Brightness and Smoothness: Both models feature adaptive 120Hz refresh rates on their displays, ensuring smooth scrolling and responsive interactions. The Galaxy Z Fold6 boasts a significantly higher peak brightness of 2600 nits, compared to the Z Fold4's 1200 nits, which enhances visibility in bright outdoor conditions. The Z Fold6 also features a new slim Flex Hinge and is rumored to have a less noticeable crease on its main display.

The camera systems on the Galaxy Z Fold4 and Z Fold6 are designed to offer versatile photography and videography capabilities, with the newer model building upon a proven foundation.

• Rear Camera System: The Galaxy Z Fold4 features a triple rear camera setup consisting of a 50 MP wide-angle lens with optical image stabilization (OIS), a 10 MP telephoto lens with 3x optical zoom and OIS, and a 12 MP ultrawide lens. The Galaxy Z Fold6 maintains a very similar camera hardware configuration, with a 50 MP main sensor, a 12 MP ultrawide, and a 10 MP telephoto lens with 3x optical zoom.
• Front and Under-Display Cameras: Both devices include a 10 MP camera on the cover display and a 4 MP under-display camera on the inner foldable screen. While the megapixel counts remain consistent, the Z Fold6 may benefit from improved image processing algorithms and the capabilities of its newer processor, potentially leading to enhanced photo quality, especially in challenging lighting conditions.
• Video Recording: Both models support video recording up to 8K at 24 frames per second. The Z Fold6 introduces improved slow-motion video capabilities, offering 4K at 120 frames per second and Full HD at 240 frames per second. Both devices also offer stereo speakers and Dolby Atmos support for an immersive audio experience during media consumption.
