I purchased Sonos move about a month ago. Absolutely happy with the product. The only problem I have is the battery seems to drain very quickly when not in use. Once I charge it full, I would turn off the main power for the charging base as well as the power of the speaker. However even that the battery would drain in about 3 days without using. Recently I notice the power of the speaker turn on its own when no one has actually open the Sonos app, neither physically turn the power of the speaker or charging base on. This could be the reason why the battery drained so quickly. Is this normal?Does anyone experience the same problem? I hope it’s not a fault with the product itself.
