Hi @panda456789, welcome to the Sonos Community!
I use Spotify Connect to stream to my speakers as well, though I use it from my computer rather than my phone. Checking the data use between both devices, I’m around 1.5GB per month which is below the average for the normal bitrate stream, but seems to be the expected amount. From what I can see on Google, the highest is around 7GB a month, so having 1GB an hour definitely doesn’t seem right.
I see that other users mention on Reddit and the Spotify forums that music videos and podcast videos can be the main culprit of a higher data use, but since you’ve disable them then we can rule that out. I don’t see anything on the Sonos side that would effect this (since we don’t need the video information), and I haven’t seen any other users mention this before. I would recommend you reach out to Spotify to troubleshoot this with them.
If you don’t make any progress, then please reach out to our support team. It’s possible this is something new that’s started occurring and, if so, support cases will be needed by our engineers for more information,
I hope this helps!
