Could anyone help me understanding what the different levels are of how apps access the Internet?
In a settings submenu there are toggles for each and every app to fine adjust (see below)
I understand what the toggles for Wifi and mobile data are. But the others…?
VPN data, I assume devices whether an app used an enabled VPN service or not…
What is the difference between background data and unrestricted usage?
What are the different level of user data that are being transmitted or not depending on the toggles on or off?
“Unrestricted data usage” is the ability to bypass the Data Saver (note), no matter of foreground/background activity
“Background data” is the ability to use data when app is not in foreground (roughly : the app is not on display). It applies to some program fetching data in background, for example email, chat, … Of course the Data Saver setting is enforced in every case.
(note): the Data Saver can be turned on manually or automatically; when turned on only unrestricted apps will be allowed to use data. This is very useful for data-limited phone plans.
