Battery drain on Android app 9.0.1

HTC U11 suffering the same problems. 49% battery use for a day the app was never used. I have just removed and reinstalled. I'll post back in a day or two.

SonosOneSteve has given a work-a-round that works for him and maybe others, but it does not explain "What Changed" having adoptive storage did not change and the version 8.6 of the app was functioning perfectly with little or no battery drain when the app was not in use, with 9.0 and 9.1 we have a massive battery hit on battery drain when the app is not in use, so again SONOS WHAT CHANGED from 8.6 to 9.x

Update to my situation on HTC U11. I removed the app, restarted the phone and reinstalled. Seems to be behaving as of today but that's only 24 hours. Strange thing was I tried reinstalling before but without the restart, maybe something was held in memory.

That's usually what I think about that too....something gets held over in memory, until the memory is "flushed" by a full reboot. It's why I often recommend a hard power cycle. I know it doesn't hurt, and sometimes it might help. And the other issue is what if it's something left over from some other program, corrupting ostensibly addressable memory?

Glad it's working now for you, hope it continues.

I uninstalled it from my phone (Android 6.0.1, Sony ), left it a week or so until I really needed the app again, then reinstalled.

Worked fine for maybe a week or so, but now we are back to the app being the main battery use every day, even when I haven't actively used it all.

Previously I had the widget as well which I thought maybe wasn't helping but I had got rid of that as well.

I'm uninstalling, will have to get by using Alexa for basic functions and then tablet or PC if I want to browse...

Same problem here, Moto G5s running Android 7.1.1 and getting unacceptable battery drain. Have tried downgrading to 8.6, but then it seems it is not compatible with the Sonos speaker itself. Raised support ticket with Sonos who responded initially with "We have not received any reports of our current version causing unnecessary battery drain."!

Anyway, I have submitted diagnostic reports to Sonos and await a reply.

Another me too. MotoG5 unacceptable (30%) battery drain attributable to Sonos app whether used or not. Right pain, version 8.6 used successfully but had to upgrade recently to add new beam to network. Have had to unistall app version 9 after cos same battery drain. Installing 8.6 also a pain & having to disable auto app update annoying ong. This has been going on for ages Sonos, come on we need a fix!

Would be interested if you see a difference with the just released 9.2 version of the Sonos software.

Thanks - will give it a go!

I'm not promising anything, mind you. It wasn't called out as a fix in the release notes, but I am curious.
