Move: Battery Drain Test

I’m watching this with interest as I want to keep the move in a bathroom, charging it elsewhere once per week.  I’m very happy to manually power on / off the move but not willing to purchase if it won’t keep the battery for a week with light use.

I did my own testing further back in the threat and I found it lost about 5% per night.  That is still not great self-discharge, it should be 5% a month,  but you should get you through a week of light use.

They specify 11 hours of playback time in general, so 30 minutes a day for 7 days is already 3.5 hours the battery (or ~33% of the battery) though plenty of real world tests show it not getting 11 hours more like 6 or 7-but its a function of volume, whether the mic is on or off, auto-trueplay on or off, not sure if Sonos ever specified what settings they used to get 11 hours.  Add in about 35% over a week with the 5% a night self discharge and a week might be pushing it.

Thanks for the sums buddyrich33, that is very useful.

After skimming through this thread it’s not clear if this is an issue with all Move speakers or a bug with some of them? 

Any owners not seeing this battery drain?

Sonos reps, is this the expected performance? 

I’m surprised for a ‘Move’ to lose 40% charge overnight sitting idle, not powered down but not being used. Is that normal?

Just recently purchased the Move but am experiencing the same issue here that many others are speaking to.  Just yesterday, charged up to 100%, used at midnight for about an hour and turned off.  By the evening, it was already down to 65%.

Sonia reps,

Any comments. I’d purchase a Move while on sale if you can give me some information. 

I bought as it was still a compelling purchase though it seems that I am likely to need to use it in a slightly different way than I planned to.  If Sonos resolve this issue then I wonder if it will be acheived by a software update so all existing units are fixed or by a hardware change.  Given there is no update from Sonos on this + there is a strong second hand market and 100 off I decided on balance to take the plunge and purchase now.

I confirm @buddyrich33 observation that, in “hard” power-down mode, the Move loses about 5% of charge per day, when in Wi-Fi mode, running under S1, with the mic disabled.  I updated to the latest S1 release and checked again, and it vacillated between 4% and 5%.  It’s possible that the software had some minor change, but just as likely estimation of charge-remaining based upon voltage across the terminals is approximation...

By contrast, a Bang & Olufsen BeoSound 1 loses only about 1% of charge per day.  Different battery sizes, different prices(!), bla bla bla, but it’s the only equivalent speaker I know of: Bluetooth mode as well as Wi-Fi mode, multi-room playback sync/join, Google Voice Assistant, and an iOS app to control it, with playback from both local library and streaming services.

Clearly “hard” power-down is not “full” power-down -- the Move is doing *something* -- much more than an idle BeoSound 1, and more even than the iOS device controlling them!

I just got two Sonos Move’s and neither holds their battery after being fully turned off. Fully charged both devices to 100%, turned them both off and upon returning to them a couple days later with no use, they’re totally dead??

Has there been any solution to this issue or do I need to return them?
