Sonos states battery life for each portable speaker and what changes it. A Move 2's 44 Wh battery provides up to 24 hours of continuous playback on a charge, and a Roam 2's 18 Wh battery about 10 hours; pausing, volume, Bluetooth, heat exposure and other factors make it fluctuate. The battery lifespan is about three years or 900 charges, after which Sonos says you can buy a replacement, and Move and Move 2 batteries fit each other, so a Move 2 battery in an original Move raises its life by about 25 percent to around 13.5 hours.
Leaving a Move 2 on its dock long-term does not reduce lifespan. Drain-related causes Sonos lists include heat, Bluetooth use and very high volume; an underpowered charger can also mean the battery never fills, so check the adapter before blaming the cell. If the speaker is on a charger and the battery still falls, Sonos says the adapter may not provide enough power. To replace a Move battery, power it off for ten seconds, lift the rubber strip, remove two screws with the hex tool and swap the battery.
Differential
Likely causes of “Sonos portable speakers battery runs out too quickly”, and how to tell them apart
- 1
The battery has aged
What separates it The battery life is a fraction of new because the battery has aged
How to confirm Consider a replacement after about three years or 900 charges
- 2
Heat exposure
What separates it The battery life drops after sitting in the sun because of heat exposure
How to confirm Keep the speaker out of heat, and out of direct sun, when it is not in use
- 3
High volume or Bluetooth use
What separates it The battery life is shorter than the rating because of high volume or Bluetooth use
How to confirm Lower volume or use WiFi where you can
- 4
An underpowered adapter
What separates it The battery never fills because the adapter is underpowered
How to confirm Use a compliant adapter, which gives enough power for the speaker
- 5
An original Move rather than a Move 2
What separates it About 13.5 hours with a Move 2 battery instead
How to confirm Fit a Move 2 battery to raise life by about 25 percent
Before you touch a setting
Record this first — changing settings destroys the evidence
- The product that you have, and how old it is
- How you use it: volume, Bluetooth, outdoors and heat
- The adapter or the charger that you use
- The battery level after a full charge and how long it lasts
Try in this order
0 of 7 completedCharge fully
ReversibleCharge fully, using a compliant adapter, and confirm one hundred percent in the app, and then test again to see whether it helped.
Check the environment
ReversibleCheck the environment, and keep the speaker out of heat, since heat wears the battery.
Lower the load
ReversibleLower the load, by reducing the volume and avoiding Bluetooth for a test day, and then test again to see whether it helped.
Time a full drain
ReversibleTime a full drain, and note how long it plays from one hundred percent, and then test again to see whether it helped.
Compare against the rating
ReversibleCompare against the rating, which is up to twenty four hours for a Move 2, and about ten for a Roam 2.
Replace if worn
ReversibleReplace the battery if it is worn, using Sonos's battery kit on a Move or a Move 2.
Contact Sonos
ReversibleContact Sonos Support if the life is very short on a new battery, giving them the model.

Stop boundary
When this stops being a self-service repair
- !If a new battery still lasts only hours, contact Sonos Support
- !If the speaker is hot or swollen, stop using it and contact Sonos
