why does my sonos app use so much bandwidth

I'd recommend disabling notifications within the Sonos app. Sonos places has a notification present in your notifications bar - it shows the currently playing tracks and can allow playback controls. https://sonos.custhelp.com/app/answers/detail/a_id/2118 You can disable them within the Sonos app under Settings --> Advanced Settings --> Show Notifications. Do you have the Sonos widget added anywhere to your Android home screen as well?

Thanks for you reply. I turned off notifications as you suggested and left the phone on wifi overnight. The app continued to use in excess of 1MB per hour throughout the night. To answer your other question, no I don't have any other widgets on the home screen. Unfortunately I am not able to take a screen shot of the MyDataApp screen showing the usage. Any other suggestions as to the cause of the high data usage while idle?

If that didn't have an effect, then we'll want to look into this with you in more details. I've opened a support ticket for you under reference number 130702-000638 and I've sent you an email. Let's continue working there so we can determine the cause of the data usage.

So how was this resolved?

And aside from bandwidth, what about energy consumption of SONOS devices when they are on stand-by, i.e., not playing music/sounds? How much is it in watts and what to do to reduce it?

Alexander. As far as I know, the sonos app only uses the internet periodically to check for updates. It doesn't use the internet for normal operation. I would suggest using an app like MyDataApp to monitor Sonia bandwidth usage. You can see what apps are using mobile data and which are using WiFi. Rob

Adil. This is the last information I have on the problem from the Sonos tech support. There are certain steps that can be taken right now to avoid this behavior. One way to avoid this is to turn off the notification option in the Sonos app under settings and delete all Sonos widgets if you use any. You would then use the back button on the Sonos app until it prompted you to exit and then select to exit The other way would be a feature request on the part of Sonos. I can understand why you want to preserve battery life and one option would be for a "status suspend" option in Sonos that would manually turn off the wifi keep alive feature Sonos is using. The downside would be a delay every time Sonos was launched to connect back to the Sonos system. This type of feature request would be submitted on the same ask.sonos.com site you used to post these bandwidth and battery concerns. Rob

Thanks for your comment Rob. 
I turned off the notification (Widget), however I liked that widget a lot. Not sure that helped,
I also turned checked the box to limit the backgrounddata, in Android settings per app. I think that  helped alot.

It is odd that so much background data was transfered. Like you comment, one would excpect a little check for updates, but not 72,79 MB in 18 days.

I will monitor the data usage now the background data is limited and I will check out the suggested MyDataApp monitor. However, whether it is wifi of mobile, this much dat is currious.

If anybody else observers the same or has insights please comment.

Sorry to resurrect a two year old thread but some time in the last 6 weeks or so I have started to suffer this problem. Maybe an update to the app? Is there a solution? Is anyone else suffering this?

I have even uninstalled the app and re-installed. This seems to have accelerated the rate at which wifi is being used. even though my Connect is switched off and I'm not using the app. I assume that the app is back to delivered default values.

I have emailed support, I'll see what they some up with. meantime does anyone out there know anything about this issue?

1.26 GB in under a week on my new Galaxy tab used by the Sonos app. Not using widgets. What's going on, folks?

Darryl, you'll have to raise a call with Sonos. Maybe if enough of us gripe they'll do something. I raised a call, I had to be persistent, but polite because first line are set up for simple problems. You'll need to get past them. Once past them I found the support guy to be helpful and understanding but the result was not what I wanted. I got the app down from 10 - 15MB / day WHEN NOT IN USE(!!!) to about 2 but once in a while it takes off again for no apparent reason.

My view is that if I'm not using the app it should be using precisely ZERO but Sonos seem to disagree. It's doing "helpful" things in the background. I was unable to determine what these "helpful" things might be but would they just not bother please?

1.26GB. Wow.

Good luck.
