Expert Review & Rating

Market Position in 2026

In 2026, the Xiaomi Mix Fold 4 operates as a compelling option in the used and refurbished foldable market, offering a high-end experience at a potentially more accessible price point. While its Snapdragon 8 Gen 3 chipset remains capable, it faces competition from newer mid-range devices equipped with more optimized, albeit less powerful, processors and potentially longer software support cycles.

The Compromises

The primary compromise lies in its plastic front display when unfolded, which, while necessary for flexibility, is inherently less durable than glass. The absence of a microSD card slot limits storage expansion, and the 16 MP selfie cameras, while adequate, are not class-leading for 2026. The lack of an explicit IP rating in the specifications suggests a potential vulnerability to dust and water ingress, a common characteristic of earlier foldable designs.

Performance & Daily Usage

Based on the hardware, the Snapdragon 8 Gen 3 chipset provides strong performance for all daily tasks, demanding applications, and high-fidelity gaming. UI responsiveness should remain fluid, and given its flagship-tier processor, thermal management was likely optimized at launch. Multitasking on the large internal display would be a highlight. The 5100 mAh battery, paired with the 4nm chipset, suggests reliable all-day endurance for average tasks. The quad-camera system, particularly with its 2x and 5x optical zoom lenses, offers significant photographic versatility, allowing for detailed telephoto shots that many modern budget phones lack. The 120Hz LTPO AMOLED display ensures smooth scrolling and vibrant visuals, making content consumption and productivity highly engaging.

The Best Features

The standout feature is undoubtedly its expansive 7.98-inch Foldable LTPO AMOLED display. With a 120Hz refresh rate, HDR10+, Dolby Vision, and a peak brightness of 3000 nits, it delivers an immersive and visually stunning experience for media consumption, gaming, and productivity. The Snapdragon 8 Gen 3 chipset provides robust performance, ensuring the device handles demanding applications and multitasking with ease, which remains relevant even in 2026. The versatile quad-camera array, featuring a 50 MP main sensor with OIS, a 50 MP 2x optical telephoto, a 10 MP 5x periscope telephoto, and a 12 MP ultrawide lens, offers exceptional photographic flexibility not often found in newer budget alternatives. Furthermore, the substantial 5100 mAh battery with 67W wired and 50W wireless charging ensures prolonged usage and rapid power replenishment, minimizing downtime for the user.

Buying Advice

The Xiaomi Mix Fold 4 is a strong contender on the 2026 used market for users prioritizing a large, high-quality foldable display and powerful performance without paying current flagship prices. However, those requiring the latest software updates beyond its initial support window or needing robust water/dust resistance should consider newer, potentially more durable, alternatives.

Frequently Asked Questions (FAQs)

Is the Xiaomi Mix Fold 4 still worth buying in 2026?

Yes, for users seeking a powerful foldable with a large, vibrant display and versatile camera system on the used or refurbished market, it offers significant value. Its Snapdragon 8 Gen 3 chipset remains highly capable, but be mindful of potential software update longevity compared to newer devices.

Is the camera suitable for low light?

Based on the hardware, the 50 MP main camera with its f/1.7 aperture, 1/1.49" sensor size, and OIS suggests capable low-light performance, as larger apertures and OIS generally improve light gathering and reduce blur in challenging conditions. The presence of Leica lenses also implies a focus on image quality.
