  • May run hotter under sustained load

Display Comparison

The Motorola Razr 2025 boasts a measured peak brightness of 1189 nits, ensuring excellent visibility even in direct sunlight. While the Mix Fold 4’s display specs are currently unavailable, Xiaomi typically employs high-quality panels. The Razr’s focus on brightness suggests a strong outdoor viewing experience. The absence of LTPO information for either device means we can’t assess adaptive refresh rate efficiency, but the Razr’s brightness advantage is a clear win for outdoor usability. The foldable form factor inherently introduces a crease; the quality of hinge design and panel construction will be critical, but data is unavailable to compare.

Camera Comparison

Without detailed camera specifications for either device, a direct comparison is limited. However, given Xiaomi’s history, the Mix Fold 4 is likely to feature a more sophisticated camera system with larger sensors and advanced image processing. The Dimensity 7400X’s ISP is capable, but the Snapdragon 8 Gen 3’s ISP offers more headroom for computational photography. The absence of information regarding OIS and lens apertures prevents a deeper analysis, but the Mix Fold 4’s chipset suggests a potential edge in image quality and low-light performance.

Performance

The Xiaomi Mix Fold 4’s Qualcomm Snapdragon 8 Gen 3 (4nm) represents a significant leap in performance over the Motorola Razr 2025’s MediaTek Dimensity 7400X (4nm). The Snapdragon 8 Gen 3’s Cortex-X4 prime core, clocked at 3.3 GHz, offers substantially higher single-core performance, crucial for responsive UI and app loading. The Dimensity 7400X, while efficient, utilizes older Cortex-A78 cores. This translates to a noticeable advantage for the Mix Fold 4 in graphically intensive tasks and multitasking. The Mix Fold 4’s superior chipset will also benefit from Qualcomm’s advanced AI engine.

Battery Life

The Motorola Razr 2025 achieves an impressive 9:28h of active use, indicating excellent battery optimization. The Xiaomi Mix Fold 4’s battery capacity is unknown, but its more powerful chipset will likely consume more energy. The Mix Fold 4 compensates with significantly faster charging: 67W wired (reaching 31% in 10 minutes) and 50W wireless (24% in 10 minutes) compared to the Razr 2025’s 30W wired and 15W wireless. While the Razr prioritizes longevity, the Mix Fold 4 offers the convenience of rapid top-ups. The faster charging speeds of the Mix Fold 4 are a significant advantage for users who frequently need to recharge quickly.

Buying Guide

Buy the Motorola Razr 2025 if you need a foldable that can comfortably last a full day of active use, and value a more compact and pocketable design. Buy the Xiaomi Mix Fold 4 if you prioritize raw processing power for demanding tasks like gaming and video editing, and require the fastest possible charging speeds – even if it impacts battery longevity.

Frequently Asked Questions

❓ Will the Dimensity 7400X in the Razr 2025 struggle with demanding games like Genshin Impact?
While the Dimensity 7400X is a capable chip, it won't deliver the same peak performance as the Snapdragon 8 Gen 3 in the Mix Fold 4. Genshin Impact may require lower graphics settings for a consistently smooth experience on the Razr 2025, whereas the Mix Fold 4 should handle it at higher settings.
❓ How much faster is the 67W charging on the Mix Fold 4 compared to the Razr 2025's 30W charging in real-world scenarios?
The Mix Fold 4’s 67W charging can add approximately 31% charge in 10 minutes, while the Razr 2025’s 30W charging will add significantly less. This means you can get a substantial boost in battery life during a quick coffee break with the Mix Fold 4, whereas the Razr 2025 will require a longer charging period for a similar gain.
❓ Does the Snapdragon 8 Gen 3 in the Mix Fold 4 generate excessive heat during prolonged gaming sessions?
The Snapdragon 8 Gen 3 is a powerful chip, and can generate heat under sustained load. However, Qualcomm has made significant improvements in thermal efficiency with this generation. Xiaomi’s cooling solution within the Mix Fold 4 will be crucial in mitigating throttling and maintaining performance during extended gaming.
