Samsung Galaxy Z Fold 7 Review: The World's Lightest Large Foldable Phone

As the pioneer and leader in foldable smartphones, Samsung has always been at the forefront of innovation in this field. The latest Galaxy Z Fold7 takes its technological strength and design philosophy to new heights. As the world's lightest large foldable phone, the Galaxy Z Fold7 has not only made breakthroughs in weight and thickness but also showcases flagship-level performance, AI functionality, imaging, and battery life.

Appearance Design: Lightweight, Slim, and Exceptional Feel

Heavy weight is a common impression of large foldable phones, but the Galaxy Z Fold7 is surprisingly light. Weighing just 215g and measuring 8.9mm in thickness, it is the world's lightest large foldable phone. This achievement is due to Samsung's innovations in hinges, screen structure, and materials. The ultra-thin, precision-crafted armor hinge adopts a droplet shape and multi-track design, ensuring a seamless fold and significantly reducing hinge volume and weight. The main display uses a titanium metal mesh layer instead of traditional carbon fiber, reducing the thickness by 39% while maintaining screen strength.

The Galaxy Z Fold7 features a 6.5-inch second-generation Dynamic AMOLED outer screen with a resolution of 2520×1080, supporting an adaptive refresh rate of 1-120Hz. The inner screen has been upgraded from 7.6 inches in the previous generation to 8.0 inches, with a resolution of 2184 x 1968 (QXGA+), also supporting a 120Hz adaptive refresh rate. Both screens support Vision Booster visual enhancement technology and a peak brightness of 2600 nits, ensuring clear visibility even under direct sunlight.

The version in hand is the Shadow Blue color, showcasing Samsung's high craftsmanship and unique aesthetic philosophy. The body adopts a deep blue base color, offering stunning dynamic visual effects under various lighting conditions. When indoors, it presents a subdued and steady color, but when exposed to sunlight, it reveals a dazzling gemstone-like glow. The back cover is made of Corning Victus2 glass, which is scratch-resistant and durable, so you don't need to worry about scratches even when placed with sharp objects like keys. The middle frame uses enhanced armor aluminum for added stability and durability. The top and bottom of the phone are equipped with independent speaker openings, creating a symmetrical stereo field. The camera module eliminates the CD decoration of the previous generation and adopts a simpler three-camera arrangement, with the monochrome LED flash on the right slightly shifted downward.

Performance: Custom High-Frequency Snapdragon 8 Elite

The Samsung Galaxy Z Fold7 is equipped with the high-frequency custom Snapdragon 8 Elite mobile platform (for Galaxy). The CPU's primary core frequency has been increased from 4.32GHz to 4.47GHz, and the Adreno 830 GPU frequency has been boosted from 1100MHz to 1200MHz. This upgrade results in significant improvements in single-core computing, multi-threaded processing, and graphics rendering capabilities. For storage, it features a combination of LPDDR5X memory and 512GB UFS 4.0 flash storage, providing flagship-level performance. In a national game test, "Honor of Kings" was played at the highest graphical settings, and during a ranked match, the average frame rate remained stable at 120.1FPS without any frame drops, ensuring a smooth gaming experience.

AI Performance: Personalized UI and AI Tools to Unlock Big Screen Value

While foldable phones may not focus too much on gaming performance, the Galaxy Z Fold7 emphasizes AI applications, providing users with a brand-new mobile experience by showcasing the full potential of its large screen. One of the key new AI features is the "Instant Briefing" function, which automatically collects weather, news, interest-based content, and music according to the user's interests and travel plans, all displayed on the 8.0-inch inner screen. When the user wakes up, they can instantly access various information in one place, taking full advantage of the large screen.

In lock screen mode, the Galaxy Z Fold7’s "Real-Time Window" feature enhances the practicality of the outer screen. Information like ride details, map navigation, and flight updates are clearly displayed on the outer screen, without needing to open the phone. In music playback mode, the outer screen can also be used to control and adjust settings, extending the usability of the notification bar.

The “Instant Search” function is likely the most frequently used AI tool. Whether reading an article or watching a video, users can easily perform real-time searches. The Galaxy Z Fold7 also introduces features like instant translation, AI homework assistance, and game strategy search, making it easy to translate content from up to 20 languages offline and continuing to translate even as the screen moves.

For students and parents, AI homework assistance can easily solve problems. By photographing or selecting questions, the Galaxy Z Fold7’s AI will provide a complete solution, steps, and explanations, covering subjects from K12 to graduate school mathematics. For gamers, the Galaxy Z Fold7 offers strategy search, which quickly finds game strategies based on the current screen, such as item builds and skill upgrades for heroes in "Honor of Kings." Additionally, its multi-modal AI assistant Bixby greatly enhances user productivity, enabling quick music creation and other tasks in just seconds.

Imaging: 200MP Large Sensor Integrated into a Foldable Phone, with Stunning Results

The Galaxy Z Fold7 is the first large foldable phone to incorporate a 200MP large sensor. The main camera uses a 200MP Samsung S5KHP2 sensor with a 1/1.3-inch image unit, featuring an F1.7 aperture and OIS optical image stabilization. The telephoto lens uses a 10MP Samsung S5K3K1 sensor, supporting 3x optical zoom and OIS optical stabilization. The ultra-wide camera uses a 12MP Sony IMX564 sensor, offering a 123-degree wide-angle view. In daylight, the 200MP camera demonstrates excellent light sensitivity and dynamic range, delivering true-to-life color reproduction and rich detail. In backlit scenarios, it captures fine details and textures, such as the 3D effect and texture of the goat sculpture. The telephoto lens emphasizes the subject, giving the photo more depth and a professional look. AI Multi-Shot is also available for those with less experience, automatically generating two photos and four videos, including Boomerang edits, Fast Rewind, Slow Motion, and Original Video for easy sharing.

Charging and Battery Life: All-Day Usage without Compromise

Despite its lightweight and slim design, the Galaxy Z Fold7 doesn't compromise on charging and battery life. It houses a 4400mAh battery, supports 25W fast wired charging, wireless charging, and reverse wireless charging. The 25W wired fast charging can charge the battery to 50% in about half an hour. Thanks to the processor's efficiency optimization and LTPO screen technology, overall battery life is better than the previous generation. In practical use, playing "Honor of Kings" for 1 hour, followed by 1 hour of TikTok and 1 hour of Tencent video streaming, consumed only 25% of the battery, providing an outstanding performance for typical daily use.
