Severe battery drain with Sonos app in iOS

To the best of my knowledge, Sonos has not been able to track down this issue, so there's been no software update that purports to fix it. However, turning off the lockscreen and hardware controls are only for the Sonos app, and not all apps, so it's not applicable across all apps, which I'm inferring you mean from your comment of "for the benefit of one app".

I have turned off lock screen just for this app. Hasn't really stopped the massive battery drain when I forget to turn off the app too from my iPhone 6.
Basically I try and use a mac or iPad - needing to save my phone battery to use (I know it's weird!) as a phone.
Yesterday I forgot to turn off app, and battery dropped to 30% in hours
Will diagnostics tell anything about my iPhone app - seems this is the issue?
Seems to have been much worse since I added two play ones to my play base and play5.
Not complaining just adding to clamour.
Does anyone with multiple speakers NOT have this as an issue I wonder?
Cheers Dom

I don't think anyone knows if a diagnostic will tell Sonos any information that will help them identify the issue. But it certainly can't hurt to submit the data, either. And if it doesn't help them track the issue, it certainly serves as a reminder that they haven't fixed this issue for some people.

I have three iOS devices currently, and have used the app on many different iPhones. I have never experienced this issue on any of my multiple iPhones or iPads.

Switched of the volume controls on Iphone X and 8 plus and saved 75% of my daily current drain. Shame on you sonos!

After updating to version 8.3 the Sonos app rapidly drains the battery on an iPhone SE running iOS 11.2.5 (42% of all battery usage in the last 24 hours, overall to cca 40%, so 25% of battery capacity goes just for Sonos used for 4 minutes foreground and 1 minute background (!)). Lock screen controls is Off (since this was suggested as a possible cause in a number of places). The app has also been deleted and reinstalled without any effect. Before the update Sonos battery usage was only a few percent. Nothing else has changed.

I uploaded the diagnostics 8420376. Sonos "solution" has been very helpful:

"We have been investigating reports from customers who are perceiving high battery usage by the Sonos app on their iOS 10 devices. The data has now been analysed and we have determined the battery usage to be reading as expected.

Our only advice to customers who do not agree with this is to force stop the app when it is not in use."

I'm experiencing the same issue since the latest iOS Sonos app update on an iPhone 8. Sonos has been using 65% of my battery whereas it definitely wasn't this high before the update. A fix would be much appreciated.

First let me introduce myself, No that’s not my real name but it;’s my favourite AKA.
I just recently purchased a pair of Sonos Play 1’s to use at my job. The music that is “piped in” by my home office is seriously enough to make you consider water boarding as a vacation getaway !
I did a lot of research and after setting up a travel router (public WIFI solution) and turning off the piped in stuff,I could not be HAPPIER !!! Excellent products with a great sound !
I too found that after using the system that both my IPad Pro and IPhone 7Plus showed a dramatic battery drain. I need to keep the app running on both units so that I can control the volume and play lists to suit my incoming guests . I have set up a desk top quick charging station on my desk and during the day I will “top off” my units . At the end of the day I shut down the app on both units and the battery level stabilizes . I have to figure the app and the play 1’s are constantly “talking” to each other all day long and that would explain the drain. I believe that if you do not need to constantly adjust the volume and change the playlist you could just close the app and the battery drain would be minimal.
On Friday I will receive the Echo dot 2 and see if that helps as well.
Other wise I am extremely happy with this set up and it” blows the doors off “any blue tooth set up I have tried in the past .
PS I did send in a Diagnostic avctivity report but I suspect that it “is what it is “ .

I just started using the Sonos app on my iPad Air 2 and the battery is draining fast as well when the app is in memory. I see this issue has been going on for 1 - 2 years and Sonos still hasn't figured out why? Also, I just tried calling the Sonos tech support and got a message about not being available due to maintenance so I'm out of luck today.

I'd recommend reading this thread in its entirety. There's at least one recommendation on how to fix this on a temporary basis, at the very least. You may want to submit a diagnostic to provide them any potential additional insight.

Here is a thread regarding today's phone and email outage:

TL:DR is that they should be back to normal tomorrow.

This issue is a new on to me. I recently added a second Play5 to my house, and since then the controller on my iPhone on and ipad are draining the battery incredibly fast. Sonos in the background, not even playing music now accounts for almost all of my battery use!?! Could this be related to a second Sonos being added to my house and grouped? Is the grouping keeping them actively talking to the network, the iOS devices and each other? I can only shake my head at how fast the drain is and how active the sonos controller is on my devices even hours after I last played music. This is not at all normal for an app not actively playing anything to doing anything to be ploughing through battery life above any other app that I am actually using like Mail or a browser.

Not resolved at all for me, and it’s certainly something new since I added a second Sonos to my house.
