Prevent Spotify using 3G on iPhone On the Spotify iPhone app, there is a manual setting to turn offline mode on or off. Ideally there would be a feature that automatically switches to offline mode as soon as a wifi connection is dropped, and switches back to online mode when connected again. Is there another way to achieve this?
You can switch off cellular data per app. Go to Settings -> Cellular and scroll to the bottom, tap to turn off cellular data for an app.
