Editorial note

The Xiaomi Mi 9 stands out with its 6.39-inch AMOLED display featuring a resolution of 2340 x 1080 pixels, providing an immersive visual experience and vibrant colors. However, visibility may be compromised in direct sunlight, which is a point to consider for users often outdoors. The user experience is generally satisfactory with a score of 85. Powered by its Qualcomm Snapdragon 855 processor and 6 GB of RAM, the Mi 9 ensures smooth usage for applications and games. Despite these performances, the 3300 mAh battery capacity may be insufficient for heavy users, limiting its autonomy. This performance assessment is rated at 80. Fast charging technology and wireless charging are undeniable advantages, but the battery capacity remains a drawback, with a score of 70 for battery life. In terms of design, the Mi 9 is sleek and lightweight, weighing only 173 g, which ensures a pleasant grip. This design quality is well-rated with a score of 90. The triple rear camera of 48 MP, 12 MP, and 16 MP allows for high-quality photos, even in low-light conditions. However, the lack of a 3.5 mm headphone jack may disappoint some users. The evaluation of features is 75. Finally, the value for money is considered good due to the performance and features offered, although the non-expandable 128 GB internal storage may be a constraint for those needing more space. This criterion receives a score of 78. Overall, the Xiaomi Mi 9 represents a solid option for those seeking a high-performing smartphone with a refined design, while being aware of its limitations in terms of battery life and storage expansion.
