I backed up and restored an iPhone 8 Plus 256GB to an X 256GB and noticed that I lost about 8GB in the X - that is, the X is taking 8GB more. When I examined things, data amounts were identical, but I noticed apps on the X take up more space than on the 8 Plus. For example, Facebook, with only 2MB of data on the 8 Plus, is about 220MB, while on the X, with the same 2MB data, takes up about 400. Others show smaller, but still there, increases. I'm assuming its a bug or some other weird optimization of apps the X is missing. Or is it just me?
