Excessive mobile data usage when playing downloaded playlists

Ok, so I have posted in this thread but there has been no further action, probably as it has a 'Solution', so here I am.  Apologies for the length.

 

iOS 10.0.2 & 10.1 - iPhone 6s - Spotify Premium

 

Backdrop, I exceeded my 4gb data usage this month within 2 weeks, normally I wouldn't reach it over the month.  Investigated usage and found it was pretty much all Spotify so started some testing, reset my mobile data usage settings, tried different streaming qualities, removed and redownloaded playlists etc etc..

 

From Saturday morning (09:00) to now (6 full days), Spotify had used 2.1gb of Mobile Data.  During this time I have not actually 'Streamed' any music over 3G/4G, at home I am on Wifi, whilst in my car I have used ONLY downloaded playlists.

If I turn off Mobile Data for Spotify in iOS settings, downloaded playlists still play fine and no data is used, however as soon as I re-enable data it starts chewing through it at a ridiculous rate.  This was all on iOS 10.0.2, so I updated to 10.1, performed the same tests and it's no different.

Today I reset mobile data again after work when I got in my car at 3:38pm, see attachment, no usage.  Then I checked after 20 minutes of playing just a downloaded playlist (about 5 songs), and there was already 368mb data used, in just 20 minutes, see screenshot.  I have also provided an additional screenshot of my setting for downloading using mobile data, which is clearly OFF and has been forever.  The songs in the downloaded playlist were downloaded at home on WiFi and are indicated as downloaded in green on the device.

 

After doing quite a lot of research, there are a lot of people having this issue, but I have yet to see any response from Spotify, apart from the fact that it may use up to a couple of hundred mb per month without streaming.  I have just convinced my wife to start using Spotify and she is currently on her free month of Premuim, then I was going to upgrade us to the family plan, but if this mobile data usage is going to continue, then I will cancel both of our plans, as my wife only has a couple of gb per month and this usage is not feasible.

 

Also, please don't bother with comments like 'just put it in offline mode' as this is not helpful and does not address the issue at all.  While yes, putting it in offline mode prevents data usage, it also removes most of the beneficial features Spotify provides, so what's the point in having it when we could use Rdio or (gasp) Apple or Google Music. I like Spotify and would like to remain with the service on a family plan, I am also happy for it to use mobile data, checking for metadata, syncing playlists, downloading album art etc. but that should be a couple of hundred mb per month, not per 20 minutes.

 

I have currently removed the app from my device and reset the iPhone.  I will look at resinstalling it and trying again, and will post here with results.

After further testing over the weekend, I have confirmed that this excessive data usage was due to my iPhone not being registered as an offline device under my Account settings.  Once I had cleared the three dveices, and re-added my iPhone, I have only used 7mb data in a week playing downloaded playlists.

 

Although I'm happy I have resolved this, it is still slightly worrying that it is so easy to do this, and there is no warning whatsoever that you have already utilised your three offline devices.  The songs still show up as downloaded on your device, and still play in offline mode, so this is something Spotify needs to look at, the three questions I posted above.

 

I shall mark this as the solution.

Ok, so after reading everything I could find on 'Offline' play, I had a think.  Then I went looking around my Spotify preferences/Account Settings on the website, and found 'Offline Devices'.  Then I thought, hmm, I have had a tablet fetish recently, and I downloaded music onto each of these tablets during my review of them.  

 

I normally have my Macbook Pro, iPhone and a tablet for listening to downloaded music, but I had now downloaded playlists onto about eight devices in total, which means my original devices had dropped off the 'Offline Devices' list as you are only allowed three.  

 

I tested this, removed all offline devices from my account, downloaded a playlist to my iPhone again, turned off WiFi and played it for about 20 minutes.  Only 2mb data used.  Problem & Solution potentially found.

 

However, three things:

1. My downloaded playists still played on my iPhone during this time, even though it wasn't one of my offline devices, and even with data off.

2. Would it not be useful to provide a notification, either within the Application or as an email that you have reached your three device limit and that you need to remove one device to add another?

3. Why couldn't someone from Spotify suggest this and save me days of headache, either through these forums, twitter or email, all of which I used?

 

Anyway, I will continue to test over the next couple of days, and confirm if this is in fact the solution, but I hope this may help others.
