I'm unable to restore an iCloud backup on my iPhone X, after it has been emptied and brought to the factory settings in recovery mode.
My iCloud backup is ~180 GB, while my iPhone 256GB. After almost one day it shows a alert that there is no more free space on my iPhone, while still need to restore 30GB.
If I check how much space is present on my iPhone, most of the memory is occupied by a gray bar (undefined).
How is that possible? Since I cannot control anything of the backup, how can I solve the problem?
