Google Play Music from phone to Sonos Connect

[Scam]

I've inherited a Sonos set up in my new place which is absolutely fantastic. Even better now that it supports Google Play Music.

The problem is that it seems to utterly rinse my phone's battery. Is this because my phone is technically 'sending' that stream to the Sonos constantly? Would a Chromecast somehow help? I was under the impression that the Chromecast actually takes the stream itself and therefore doesn't use your phone/controller's battery anywhere near as much.

So can you go phone > Chromecast > Sonos > Amp somehow?

I'd say I could just do Phone > Chromecast > Amp but we have a second speaker in the corridor and ones on the terrace as well, so it needs to go via the Sonos.

Are you casting from the google music app?. I use the Sonos app and have my google account set up in it, doing it that wayI have never noticed any additonal battery drain.

Yep from the Google app. It's an inherited Sonos system but I was wary of updating it unless I broke anything So havent tried it through Sonos itself.. Perhaps I should.
