Question about Sonos Roam

I also often operate the SONOS Roam from the mains. Unfortunately, that's not so good, because it has a lithium-ion battery and it's best to keep it between 30-90%... So I unplug it at least once a week and let it discharge to 30% - then I plug it back into the mains. I'm also curious how old the battery will get!

I can't answer that for sure.
Since I'm charging it, then I need it without charging. Still waiting for the charging station.
