Expert Review & Rating
Market Position in 2026
In 2026, the Samsung Galaxy Z Flip4 occupies a niche as a compact, foldable option primarily for the used or refurbished market. Its hardware, while dated, still offers a distinct form factor that modern budget and many mid-range alternatives do not.
The Compromises
The most significant compromise is the 3700 mAh battery, which is notably small for 2026 standards and will likely require frequent charging for even moderate use. The 25W wired charging is slow compared to contemporary devices, meaning longer wait times to top up. The dual 12MP camera system, while competent for its time, lacks the versatility and computational photography advancements seen in current mid-range phones, particularly in low-light scenarios or for zoom capabilities. The plastic front display, inherent to early foldable designs, is also a durability concern compared to glass slab phones. Finally, the absence of a microSD card slot limits storage expansion, which could be a drawback for users with extensive media libraries.
The Best Features
The defining feature remains its foldable design, transforming a large 6.7-inch display into a pocketable form factor, offering unparalleled portability among smartphones of its screen size. The Foldable Dynamic AMOLED 2X display with a 120Hz refresh rate still delivers vibrant colors and smooth scrolling, providing a premium visual experience that holds up well. The Snapdragon 8+ Gen 1 chipset, while no longer cutting-edge, provides sufficient processing power for everyday applications, web browsing, and even some older mobile games without significant slowdowns. The continued software support, with an upgrade path to Android 16 and One UI 8, ensures it remains functional and secure, extending its usable lifespan significantly. Additionally, the inclusion of wireless and reverse wireless charging offers a level of convenience not always found in budget-tier devices today.
Performance & Daily Usage
Based on the Snapdragon 8+ Gen 1 chipset, the Galaxy Z Flip4 should still manage daily tasks, app switching, and social media browsing with reasonable fluidity. UI responsiveness, supported by the 120Hz display, is expected to be smooth. Given the 4nm process, thermal management for routine use is likely adequate, though sustained heavy gaming or demanding applications might lead to noticeable heat generation and potential performance throttling compared to newer, more efficient chipsets. The 3700 mAh battery will necessitate careful power management or frequent access to chargers. The dual 12MP camera system is capable of capturing decent photos in good lighting, but its performance will be outmatched by modern budget phones with larger sensors or more advanced processing in challenging conditions.
Buying Advice
This device is a viable option for users prioritizing a compact, foldable form factor on a tight budget, particularly as a secondary device or for light usage. However, those seeking competitive camera performance, all-day battery life without charging, or cutting-edge processing power should explore newer, non-foldable alternatives in the mid-range market.
Frequently Asked Questions (FAQs)
The Samsung Galaxy Z Flip4 can be a worthwhile purchase in 2026 for specific users on the used or refurbished market who prioritize a compact, foldable design and have modest performance demands. Its aged battery and camera system are notable limitations compared to current devices.
The Snapdragon 8+ Gen 1 chipset, while no longer a flagship processor, still delivers competent performance in 2026 for most daily applications, web browsing, and light to moderate gaming. However, it will not match the efficiency or raw power of current-generation premium or even some upper mid-range chipsets, especially under sustained heavy loads.
