Price and Availability
The Xiaomi Mix Fold 4 was launched in China in July 2024, with plans for a global release. However, exact timelines and regional pricing remain unconfirmed. As with previous Xiaomi releases, a U.S. launch is unlikely.
In China, pricing is as follows:
- 12GB + 256GB: CNY 8,999 (~$1,280 / £955 / AU $1,885)
- 16GB + 512GB: CNY 9,999 (~$1,422 / £1,062 / AU $2,094)
- 16GB + 1TB: CNY 10,999 (~$1,564 / £1,168 / AU $2,304)
While these prices may seem competitive compared to the Samsung Galaxy Z Fold 6 ($1,899) or Google Pixel 9 Pro Fold ($1,799), expect regional adjustments in pricing for other markets.
Design and Display
The Mix Fold 4 features a 6.56-inch cover display with a 1080p resolution and a 21:9 aspect ratio, making it comfortable to use in folded mode. The LTPO panel supports adaptive refresh rates from 1-120Hz, HDR10, and Dolby Vision. Despite its 9.5mm folded thickness, it is slimmer than most competitors.
Unfolding the device reveals a 7.98-inch inner OLED screen, also with 1-120Hz adaptive refresh, HDR10+, Dolby Vision, and an impressive peak brightness of 3,000 nits. The inner display offers excellent visual quality for watching movies or gaming, though the crease in the middle is noticeable and may disrupt smooth navigation.
Camera Performance
The Mix Fold 4 boasts six cameras:
- Rear:
- 50MP wide (main)
- 50MP telephoto (2x zoom)
- 12MP ultrawide
- 10MP periscope telephoto (5x zoom)
- Front: Two 16MP selfie cameras (one on each screen)
The camera system, enhanced with Leica optics, offers vivid colors and bright photos but struggles with over-processing in some scenarios. Compared to competitors like the Google Pixel 9 Pro, the Mix Fold 4 delivers mixed results:
- Daylight shots: Bright with vivid colors but sometimes exaggerated.
- Low light: Impressive detail and clarity, outperforming the Pixel 9 Pro in some cases.
- Selfies: Disappointing, with noticeable over-smoothing and artificial effects.
- Portrait mode: AI-enhanced results may appeal to some but can look overly polished.
Performance
Powered by the Snapdragon 8 Gen 3, the Mix Fold 4 delivers excellent performance, surpassing many rivals in benchmarking tests:
- Geekbench 6:
- Single-core: 2,203
- Multi-core: 7,020
- 3DMark Wild Life Extreme: 3,929 points (23.5 fps)
Gaming on the Mix Fold 4 is smooth and lag-free, with effective cooling that keeps the phone from overheating.
Battery and Charging
With a 5100mAh battery, the Mix Fold 4 offers impressive endurance. In a 3-hour YouTube video playback test (50% brightness), it lost only 14% of its charge, outperforming rivals like the Galaxy Z Fold 6 and Honor Magic V3.
Charging is quick with the included 67W wired charger, which takes the phone from 0-59% in 30 minutes and reaches a full charge in under an hour. Wireless charging is supported at 50W, but a compatible Xiaomi charger is required.
Software
The Mix Fold 4 runs on HyperOS, Xiaomi’s custom Android 14-based skin. The Chinese variant includes regional services, but global models will feature Google services.
Conclusion
The Xiaomi Mix Fold 4 impresses with its sleek design, top-tier performance, and strong battery life. However, the camera system, especially the selfie cameras, falls short of expectations. While pricing in China is competitive, its availability and pricing in other markets remain key factors in determining its global success.
If you’re looking for a foldable with premium specs and solid performance, the Mix Fold 4 is a worthy contender, provided its limitations align with your needs.
