iPhone full Backup possible? I am updating my iPhone from a 6 to 8.
I wanted to move everything including passwords from the old phone, and I understood that I needed to perform an encrypted backup. 

The file is 23.33GB vs the 53GB storage used on my phone. Is the file compressed to account for this or does the full backup not include everything on the iPhone?
The full backup does not include:


iOS itself (since that will already be on the other device),
app bundles (since they will be downloaded from the App Store again).


App data is backed up even if the apps themselves aren't. It's as full of a backup as is available and will back up all of your data.
