FAQ
How long should I charge my Sonos Roam before trying to turn it on? Charge for at least 30 minutes if the battery was completely drained. A fully dead battery may not respond immediately to power button presses.
Why doesn't my Sonos Roam show any LED when charging? A completely depleted battery may not display LED indicators for the first 10-15 minutes of charging. This is normal behavior for lithium-ion batteries.
Can I use any USB-C cable to charge my Sonos Roam? Yes, any quality USB-C cable will work, but using the original Sonos charger ensures optimal charging speed and compatibility.
How do I know if my Sonos Roam battery needs replacement? Check battery health in the Sonos app under Settings → System → About My System. Significantly reduced playback time or failure to hold charge indicates battery degradation.
