Thank you for your attention. The gap between the battery cover and other components of the Xiaomi 15 Ultra has been carefully designed with strict quality requirements in mind. The phone undergoes comprehensive inspection to ensure that it meets Xiaomi's high standards for performance, durability, and overall quality before it leaves the factory.
The appearance of the gap can sometimes appear slightly larger or uneven due to the design and manufacturing process, as well as the integration of different materials and components. However, this gap does not indicate a defect. The battery cover is carefully aligned to allow for optimal function and protection, and the device is specifically designed to ensure long-term durability.
Additionally, the Xiaomi 15 Ultra undergoes rigorous waterproof and dustproof inspection to ensure it can meet the IP68 grade standard, meaning it is highly resistant to water and dust ingress. Please rest assured to use it.
