Data Usage iPhone 7

[Elritzo]

Dear community,

Since I use my iPhone 7 my data usage is extremely high! In four days I used about 850+- MB. 

What did I do?
Since I have a 128GB iPhone I saved all my playlist offline (about 1000 songs), deactivated download through mobile carrier, and still my Spotify uses a lot of data. This morning about 100MB! 

What can cause this problem? How do I solve it? In my opinion I saved all my playlists offline so there should be a usage of 0 MB. A little usage is OK, but this is strange in my opinion.

I don't know the answer to your question but I have a premium account and am able to download songs and play them offline. Go to the downloads section of your app and they should appear there. There is probably another thread that better answers your question. Good luck.
