The edge of metal frame is processed with inclined chamfer transition, which is convenient for charging plug insertion.

IPhone 11 Pro smart battery case is a customized product for iPhone 11 pro. We simply test whether the same 5.8-inch iPhone XS is also compatible.

The location of the original iPhone 11 Pro camera is completely wrapped around, and the camera module is exposed outside, which fits perfectly.

After the iPhone XS is installed into the smart battery case, a large area is left on the right side of the vertical camera. The vertical dual cameras are exposed in isolation. Although it can be installed in, it feels a little strange.

The mute key of the unique logo of the iPhone obviously deviates from the opening position of the iPhone XS here. It can be seen that the battery shell of the iPhone XS can be installed, but it doesn't fully fit the iPhone XS. Moreover, the three sides of the iPhone XS are about 1mm smaller. After being installed, it is loose and dynamic.

Plug in the data cable, the orange electricity indicator in the microfiber lining will be on, and the battery shell can be charged separately from the mobile phone.
