Battery drain on Android app 9.0.1

Sorry if I am being a bit stupid here but can someone give me an idiots guide to getting back to a previous working of the software on my phone please. I have auto update off so can then never touch a Sonos update

I see I'm not the only one with this problem - the latest update seems to have caused the app to consume more battery than the screen, even with notifications and lock screen off! I've had no choice but to uninstall the app as killing it, clearing cache etc, none of the usual things fixes it.

Any update on the progress please? Do you need more information from us?

Today, a new version of the controller was released for Android. Nothing has changed 😞 Seriously Sonos? Two month and no status update, is anybody actually looking into the issue? I'm deeply disappointed.

Sonos, please! Can you at least give us some hint of you trying to fix the battery drain issue?

I tried downgrading to 8.6 to avoid the problem, but that version says there is a newer version, and I HAVE TO upgrade to use it. My battery went from 75% to 55% in two hours without me even using the phone. Why? Sonos. It is ridiculous.
So, now I have to uninstall the app. This CAN'T go on.

Just a quick "me too". I've had to uninstall as Sonos was chomping through 25% of my battery and by 6pm I was looking for a charger.

I've also been forced to uninstall. Force stop didn't work. It's a battery killer on my sony E6653 android version 7.1.1. I was thinking of buying a Sonos soundbar. Not so sure now if they can't fix this in a reasonable time. I was really liking Sonos until now.

Can we get an update on this please? This is staring to make my phone unusable as it needs to be plugged in all the time.

I'm sitting here refreshing the battery usage stats. The app isn't even open yet CPU total is constantly increasing, as is data received via wi-fi, data sent via wi-fi and computed power usage.

What on earth is it sending over wi-fi when the app isn't even running and why is it using CPU?

I ran in to the 'can't go back to 8.6' issue, once the latest Sonos 9.1 app had been installed. Tearing my hair out at the time..

Now here's something I did that seems to have completely fixed my Sonos 9.1 excessive battery usage on my Moto G5 android 7.0 phone!

1. Check if you have an SD card installed.
2. Check if you are using Adoptive storage (Androids rather poor way of trying to share SD memory with internal memory.
Even with a super fast SD card as I have it seems to cause problems.
3. If you are using adoptive storage and can take the hit on some apps that are allowed to be stored on the SD card going missing - stop the adoptive storage, reformat the SD card and use it for Photo, video / Spotify downloads but no apps and reinstall the apps you have lost on internal memory.
4. For good measure uninstall the Sonos 9.1 app and reinstall again.
To find the storage settings you need; Goto Settings / Storage / Portable Storage, Three dots at top right, Storage settings.

I found this totally fixed my Sonos app battery usage woes. Most days now the Sonos app doesn't even register on the list of battery hungry apps!
Today for example it's used 7m 3s CPU total and 20mAh. At worst it was 4 hours CPU and nearly 400mAh! What a difference.
The Sonos app now uses less than Spotify .

I have advised the Sonos support team of the above and suggested they advise other customers to try the above, but they have not even responded to me in over 5 days!

Could this be the cause of a relatively few customer devices having this massive battery draining issue with the Sonos 9.0.1 and 9.1 app installed and others being absolutely fine? - maybe?

Why? Who knows, perhaps critical Sonos data gets stored on the SD card and as the app is on internal storage, it's fragmented somehow and data retrieval goes in to hyperdrive, hence the CPU time and current drain - I guess I'll never know!

Do let me know if this helps your Sonos batt drain woes.
