Roam: turning itself on

That the roam turns on again if you have turned it off completely before, only happens when it‘s connected to a QI charger. The reasons are how QI charging works and the fact, that roam always turns on if it‘s connected to a power supply. 
If connected to power source using the usb c cable roam can be turned off completely and stays so. 
As a result of this roam only can be powered off completely on battery mode or being connected to power supply with usb c. 

I have the same issue. It turns on on the wireless charger. The thing is when it fully charged first, it seems stop charging and it keeps turning on. As a result, the battery is draing on the charger.

For the battery there is no problem in this case. Roam will charge fully and stop charging at 100%. 
Only thing made by design is that you can‘t turn off roam completely if it‘s placed on a QI charger. 

Don‘t know who marked this as best answer, but imo it‘s not the answer, because the question was why roam automatically turns on again after turning it off while still standing on the wireless charger. So imo what is written above doesn‘t work…

You can‘t turn off roam completely without turning on automatically after some time if it is connected to a wireless QI charger. 

I’m in the same club, turn off Roam NOT ON CHARGER or plugged in and yep, come back to it and it’s either dead or on.   Kind of pointless for a battery powered device to not keep itself turned off when not charging or in use.  If I turn off a device I expect it to stay off.   I’ll wait another week for a good answer or fix otherwise both units go back as defective and won’t be replaced.  This is a horrible design.

Have you really turned it off? (press and hold the powerbutton for about 5 seconds) 

Or have you just pressed it for a second and it went to standby mode?

@Schlumpf Both.  Even if I only put it into Stand By mode it should not turn itself back on and “should” last 10 days in this status.  Per Sonos docs you take the Roam out of standby mode by pressing the power button again.

What’s happening is the Roam is dead the next day and I have to charge it, so yes it’s fully powers back on or standby mode is 1 day not 10.

Waking up from standby by opening the app is made by design. But turning on just should happen by pressing power button or connecting to power source. 

@Schlumpf  What brilliant person thought it was a clever idea to wake up a battery powered speaker by opening the app?  I have other Sonos speakers in the house that I use daily so having these portable speakers turn on; especially when NOT plugged in is a horrible idea.

I’ll be sending them back.

Update:  Just looked at both units - one is completely dead again, fully charged last night.  The other has 15% left and sure enough I did check and yep, you open the app and the Roam wakes up.  Again, if being charged this might be a clever idea, but on battery it is not.

That said, I cannot get this Roam to turn off.  The instructions say, “To power off Roam, press and hold the button on the back of your Roam for at least 5 seconds. You will hear a chime and the status LED on the front will turn off.” but what really happens is it goes into Bluetooth pairing mode.   It never shuts down if I hold the button.

If your Roam can’t be turned off i suggest to call the support team.
