So last night I charged my Roam to 100%. I then unplugged it from the charger and it went into sleep mode. Then I went to sleep.
When I woke up, with ZERO use of both the Roam and my Sonos system, the Roam battery was down to 91%.
So this means it dropped almost 10% in roughly 8 hours. Which would be, generously, -- roughly 25% over a 24 hour period. Which means it would last only about 4 days in sleep mode.
Sonos says it should last 10 days in sleep mode. Do I have a bad battery? What are others seeing in this regard?
