How many band displays can be installed on the Xiaomi Smart Band 9 Pro?

The Xiaomi Smart Band 9 Pro comes with 10 pre-installed band displays and reserves around 15MB of storage for additional band displays.
For your reference, here are more details about the number of installable band displays:
1. This storage is shared with the photo band display feature. Since each band display has a different storage size, the number of installable band displays varies. However, the total number of band displays, including the pre-installed ones, cannot exceed 30;
2. You can install up to 20 additional band displays, bringing the total to 30 band displays (including the 10 pre-installed);
3. Regular band displays take up around 0.5MB of storage. More elaborate designs, such as style-based band displays, will use more storage, sometimes several megabytes.
