Move: Battery Drain Test

Day 3 results - 86% remaining.  Played some music to my Amp (Lounge) zone yesterday.  Move showed as offline when I did so.

14% in 3 days in a supposedly off state is a rather high self-discharge rate for a Li-Ion or Li-Polymer battery.  I never observed it as being online in the app when I used it with other Sonos speakers and it was always off when and I hard to turn it back on to check the level in the morning before I posted.  Doesn’t rule out that it doesn’t come on overnight but it was never my observation.  However if its not coming on overnight, I don’t know what explains that discharge rate - is the battery not lithium-ion?

One other thing to note, I was in WiFi mode.  After this mornings level check I immediately turned it off.  Decided to turn it back on again.  The light blinks as it boots up and it takes a few seconds to connect to wifi as it is powered on.  In doing so the battery level was now at 85%,  So just the bootup process used 1% of power (or the 86% reading was right on the cusp of 85-85 ).  So I did another test, right after I powered down (via 5 second push and sound effect), I powered back up 2nd time to try and gauge battery used in a boot-up/connect to wifi sequence but the battery was still at 85% so booting up doesn’t eat that much power on its own.

It would be interesting what the self-discharge rate is if left in bluetooth mode only and this same test is performed over a few days.

Day 4 results 81% remaining - I didn’t get a chance to use the Move yesterday due to rain so have some results.  Nothing much to say - its seems to be losing ~5% a night while supposedly completely off.

I have never observed it turn on on its owns but that is a fairly bad self-discharge rate.  I hope this is a bug and not as designed as I do want to use this for car camping/RVing and might stowe it off charger while travelling to campsites.

This was from a new Move I took delivery of June 5th so the battery shouldn’t be aged.

I did a less controlled test! After using the Move last night, it was down at 32% at 1.01am. I turned it off completely so it was showing up as “offline” in the Sonos app.

I just turned it back on, at 6.51pm, so almost 18 hours later, and the battery is showing 15%, so it’s lost ~1% per hour while supposedly off.

Running S2, and I was using the rest of the system throughout today but the Move always showed as “offline”.

Really disappointing.

@Ryan S 

When supposedly completely off I would expect almost zero discharge from a Li-Ion battery over 3 days but even call it 1—2%, something just isn't right with 14% discharge over 3 days.

When properly ‘off', there should be no real power usage or any expectation of WOL ‘listening' or the ability to wake from App.

@jamrolu, when you turned it back on, did it seem like it was waking up from being in standby or from being turned off? The team is working on an issue where sometimes the Move will power back on after it’s been shut off, which has caused some issues with these tests.

@Ryan S how do I tell the difference? Is there an amount of time or a chime or whatever which would make this clear? The app showed it as offline before I turned it on.

If it was powered off, the lights on top would flash white as it’s booting up and it would take a little while to show up. If it was in standby, it would come up right away, likely with no lights flashing on top. 

Thanks @Ryan S - in this particular example it booted up.

Just registering my interest in this as I’d like to get a Move but not with the sort of battery discharge being reported. If I get one, it will be for the bathroom and will be powered off for a week probably between each use as I’d only use it when in the bath and not when having a shower.

Hi All

my Move is four weeks old. Used it in the garden for a few days initially and then left it ‘off’ for a couple of weeks and went to use it again yesterday. 
discovered no battery left and spent the evening trying to understand why that was. 
I seem to have the same problem as everyone in this thread - battery level drops rapidly, even when not is use/turns on when opening the App etc. 
have a lot of other Sonos products which I love so am very disappointed with this issue. 
Move sounds good and is expensive - I paid for sound quality and battery life but am not getting the latter.
