Sonos Move battery draining when powered off

Do not believe anybody telling you, that it does not harm the lithium ion battery to be fully charged all the time. Also Sonos does not have the magic lithium ion battery.

If you keep the battery between 10% and 80% charge, it will survive much longer. I observe this for many years on different devices including the device I am currently typing on: 7 years old, 1600 charging cycles, still 90% of the design capacity. I am sure my Moves wil behave similarly.

Bought my product this week thinking that this issue would be resolved by now. The exact same issue replicated. That is a big fail from Sonos!

I have two Moves and if set to Battery Saver on they last weeks.  With battery saver off it depends how open the app is opened for.  Every time you open the app the Moves wake from standby, even if you are not using them.  If they go to sleep on the battery saver they will last ages but you will have to press the power button to use them again.

Another thing you can do is to put the Move into deep sleep by pressing the power button for 7 seconds, you should hear one tone then another tone.  Again once in this mode it takes manual button power push to wake them.

Other than an issue on one of the updates earlier this year, both the moves I have are excellent and when off base I get a good 8-10hrs of usage.

I'll try to summarize. Your Move drains battery.  If in the configuration you put the battery save switch on AND you don't configure any assistant (no Alexa no Google) Move ,switched off ,drains from 5 to 7% of the battery each day. Move will drain the battery to 0% in 17 to 20 day. If you stay off home for more than 15 days you have two choises.

  Leave the Move on the charger, but as far as I know a lithium battery doesn't like to stay at 100% of charge for a long time and in any case are you confident leaving a lithium battery on charge for a long time when you are off ?.

Don't leave the Move on the charger, but as far as I know to slowly discharge a lithium battery and leave it discharged for some time is the best way to destroy it.

In general the known autodischarge of a lithium battery is 3% each MONTH. It seems we have a problem.

So, the choice is not simple but may be that Sonos guys can help us.

Stay safe and enjoy the music.

My Moves stay on the charger for months at a time.  They are used as outdoor speakers but get little use in the winter,  I did use them outside last week and the battery capacity seemed as good as when I bought them.  Had them for nearly 3 years now on this regime and they seem fine.

Dear bockersjv as soon as someone is writing about this battery problem you are answering that everything is perfect.  I'm sorry but what you wrote answering to Apikos (If they go to sleep on the battery saver they will last ages) is clearly not thruth. There are also videos of very good tests done on youtube. Some of these are done by guys loving Sonos products but they found that the battery draining is real . 

Of corse depends on how the Move is used. This is why my question was about what to do when I don't use the Move for more than 2 weeks,  for example because i'm not at home. If i'm at home i can use and charge it all the times it's needed. 

To let you better understand the discussion in this topic i'll do an example. I have an ebike.  I can leave it fully charged but not on the charger for 3 months and at the end discover that the battery is still 80% charged.

This is not happening with the Move. 

This is my experience, nothing is perfect and can never be with battery devices that have to adhere to the laws of Physics.  I am merely recounting that I leave my Moves on their charging base between use and the batteries are still fine. So that is an alternative if you are finding them not holding their charge when off the base for more than a week.  The batteries do not seem to have been affected by the constant trickle charge.  You could leave your moves on their charging bases with Smart Plugs at the wall socket then you could turn them on before you return home? Or just have them charge an hour a day?

If I were to leave them OFF the charger for months at an end I would ensure they were fully off but long pressing the power, like I do my Roams.  The Roams loose very little Battery power in this mode, but I don’t do this for the Moves.

What I will say is I find it frustrating the the Move does not have exactly the same functionality as the Roams, and maybe this is also true for the battery management?  After all is said an done it is just a big version of the Roam.  Maybe that is why The Move 2 is being rumoured?  There’s obviously something fundamentally different with the circuitry that means they differ in function and performance. 

But hey I was just giving option to try an help.  Won’t bother again though.
