The updater will use incremental updates to download only changes rather than the - whole OS unless the current version is behind the current release by more than 3 - versions. As long as you have working network connectivity on a regular basis and - reboot when asked, you'll almost always be on one of the past couple versions of the - OS which will minimize bandwidth usage since incrementals will always be available. If - you fall more than 3 versions behind, it will download a large full update shipping - the full OS so it can update from any version.

The updater works while the device is locked / idle, including before the first unlock since it's explicitly designed to be able to run before decryption of user
