Why does the Xiaomi 15 Ultra battery cover have black spots and impurity spots?
The Xiaomi 15 Ultra features a carefully crafted battery cover designed to offer a delicate appearance and a soft touch. To achieve this premium look and feel, a surface spraying process is used during the manufacturing of the battery cover.
During this spraying process, fine dust particles in the air can sometimes settle on the surface of the cover, leading to the formation of small black spots or impurity spots. These spots are typically minor and occur as a natural byproduct of the spraying technique. While they can be visible under certain lighting conditions, this is a normal phenomenon and part of the manufacturing process.
Rest assured, this does not indicate a defect or quality issue with your device. The phone undergoes strict professional inspection and quality control before leaving the factory to ensure it meets Xiaomi’s high standards for both performance and appearance. The presence of these small spots will not affect the overall functionality, durability, or user experience of the phone. Please rest assured to use it.
