What I want to accomplish:
I want the Spotify app to use only WIFI to download/stream stuff. I want the app to never use mobile data at all.
What I have:
Premium, Android 12, Fairphone FP4.
What measures I've taken:
1) I my phone settings -> apps -> Spotify -> mobile data and wifi: I have the backgrounddata option set to OFF (that is, the small dot is on the left side of the slider and the slider is grey). The description of the slider says: "Activate usage of mobile data in the background".
2) In my phone settings -> Network and internet -> Data saving: I have the datasaving option set to OFF. In that view, I can see that I have two apps that have unlimited access anyway, Spotify is not one of them, and digging further into the list where I can manage access to unlimited data, Spotify is already no manageable in that list, it says "Background data is deactivated" (which is probably due to my points 1) and 3) )
3) In my phone settings -> mobile network -> Datausage of apps: I can see that Spotify has used over 100Mb of foreground mobile data during the last month; the Backgrounddata option (which I believe is a clone of the one in my point 1) ) is set to OFF.
4) In the Spotify app -> settings -> Datasaving: I have the option "Save data" turned OFF. The description says that activating this button would set the sound quality to "low", and that is not what I want. It does not state that it would restrict data traffic to only the one (WIFI) or the other (Mobile) data channel.
5) In the Spotify app -> settings -> Playing: I have the Offline mode turned OFF. I still want to stream on WIFI networks, so a complete offline mode is not what I want (and, obviously I understand that the feature is meant to be for temporary usage, rather than a permanent preference setting)
6) In the Spotify app -> settings -> Playing: I have the Seemless play option set to OFF.
7) In the Spotify app -> settings -> Devices: I have the setting "Spotify Connect in the background" set to ON. I reckon this has to do with using your phone to decide what songs to play on another device, e.g. a speaker somewhere in my appartment. I notice that the initial setup of such speakers often requires the user to give the speaker internetaccess and access to the location of the phone you use to set them up with. I am skeptical as to why this really is necessary, except for certain features. Both my steering device and the listening device are on the same WIFI-network, why would they need internet access. Can it be the case that there is some data leakage going on here? In any case, it should not be 100Mb in 30 days.
😎 In the spotify app -> settings -> Sound quality: I have the setting "Download via mobile network" set to OFF. Yes, typographically it looks like this setting belongs insid the category "sound quality" although its description makes me think it is more general. This setting should be the only one needed, to accomplish what I want: have Spotify not touch my mobile data at all.
Still, like I said in 3), Spotify uses data. It is the app that uses the most data. If i watch Peertube and leave the bounds of some WIFI-network, the streaming will stop. If I listen to a podcast and leave the bounds of WIFI, I'll soon get a warning, telling me that I'm about to reach my datalimit. What more do I need to turn off?
