The Xiaomi 15 Ultra features a more reliable half-pack design, which prioritizes both durability and functionality. In order to enhance the protection of the battery cover and prevent potential damage in certain use scenarios, the metal thickness and height of the cover have been specially increased. This added thickness helps safeguard the phone’s internals against external pressure and potential impacts.
However, due to this added protection, there can be some areas along the edges or corners where the metal finish is slightly raised. These raised areas or edges, particularly in the case of certain finishes, will feel a bit rough or cause slight discomfort, especially if the phone is held in the hand for long periods of time. This is a trade-off for the improved structural integrity of the device.
If the discomfort is significant, it is advised to use a protective case, which can provide both enhanced comfort and additional protection for the battery cover and device as a whole.
