Xiaomi Mix Fold 4

The Xiaomi Mi Mix Fold 4 is an impressive device that packs a big battery, wireless charging, and four cameras into a remarkably thin body, measuring less than 5mm in thickness. This feat is unprecedented among affordable phones, making it the best option for those who value portability. While the phone's features are similar to most flagship devices, its unique design makes it stand out. The camera module bulges out slightly, and the tightly shot hinge and rounded frame make it slippery to hold. However, the creases on the screen may be a turn-off for some users. The Mi Mix Fold 4's processor is still the Snapdragon Agent 3, which performs decently but not exceptionally well in gaming tasks due to heat dissipation issues. The camera setup is improved with a higher-quality standard lens and support for in-sensor Zoom, but lacks optical image stabilization, making night photography less reliable. The phone's battery life has been improved, but charging speed hasn't kept pace with the increased capacity. While it's not a significant upgrade over its predecessor, the Mi Mix Fold 4 remains an excellent option for those who value weight and thickness. Its price point is still competitive, making it a great choice for most users. Ultimately, the Mi Mix Fold 4 is a solid device that excels in specific areas, such as portability and camera quality. While it may not be a revolutionary upgrade, its unique design and improved features make it worth considering for those who prioritize these aspects.
