Move: Battery Drain Test

Still Testing.

And your results are…………………

Battery Life

Here are the results of my two Sonos Move Battery Drain tests.

Test One_4 Days starting at 98% battery charge

• Removed the Move from Charging Ring
• Set Move to BT Mode to dis-engage Wi-Fi
• Depressed the Power Button
• Move went Dark (no LED’s illuminated)
• Move not visible in Sonos App
• At the end of 4 days Move showed 37% battery charge remaining
• Average discharge per day calculation_98% - 37% = 61% / 4 = 15.25% avg.
• Based upon 15.25% average daily discharge the Move battery would be depleted in 6.4 days (98% / 15.25% = 6.4)

Test Two_7 Days starting at 100% battery charge

• Removed the Move from Charging Ring
• Depressed the Power Button until verified “Ding” was heard
• Move went Dark (no LED’s illuminated)
• Move not visible in Sonos App
• At the end of 7 days Move showed 1% battery charge remainig
• Average discharge per day calculation_100% - 1% = 99% / 7 = 14.14% avg.
• Based upon 14.14% average daily discharge the Move battery would be depleted in 7.07 days (100% / 14.14% = 7.07)

The 0.67 day difference between Test One (6.4 days total drain) and Test Two (7.07 days total drain) IMO is negligible.

Test results versus Sonos statement of 120 hours of Move battery life; if left off charging Ring and unused.

• Test One at 15.25% average daily battery drain indicates that at 100% charge the Move battery would be useable for 6.5 days or 156 hours. Allowing for error the Sonos claim of 120 hours is supported.
• Test Two at 14.14% average daily battery drain indicates that at 100% charge the Move battery would be useable for 7.07 days or 169 hours. Allowing for error the Sonos claim of 120 hours is supported.

So there you have it. Just bare in mind that my tests were conducted with no control subject in my home environment. Laboratory testing would most likely yield more accurate data. However, I feel confident in publishing my results for your review.

Cheers!

I’ve just tried it, turned my Move off completely when on wifi, it was at 100%, 4 days later it was at 71%.

Why is it consuming battery when supposedly completely turned off

I’d be interested to know the answer to this question too. My other devices don’t use this much battery when turned completely off so I’m baffled as to why the Move battery will drain completely after a week (according to the other tests).

It’s the thing that is stopping me from buying one of these.

Surely if Alexa is switched on and permanently waiting to be woken up, that will reduce battery life.

Interested to know if you switch Alexa off, whether battery life is better or not ?

I’d have thought that if you switch a unit off completely then any to do with Alexa would also be off, although I’m only guessing :)

I emailed Sonos support to ask them about this but only got a reply telling me how long the battery lasts when in standby even though I specifically said that the unit was apparently switched off completely.

I’ll see if I get another reply answering the actual question I asked :)

I’ve had another reply from support (see below). Can people who have done tests on the battery life say if this is what they have done during their tests please? I need to know of the battery is still draining even when the below process is done. Thanks :)

In order to power off the Move completely however, you would press and hold down the power button for at least 5 seconds, and wait for it to power off completely. Then you will notice that a quick power on button does not bring it back to life right away, but rather holding down on it will get it to boot up and the LED will go through the flashing white which indicates the OS starting up

Yeah that’s what I did, held down for 5 seconds until it powered down.
