I will contact the Australian office and clarify.
If I played the SoundLink Mini II Special Edition everyday for 8 hours at a time, how long would the life expectancy be of the battery?
@Pcake, you can expect at least 70% of capacity at the 300th charge cycle. 😊
In terms of charging. Is it better for the longevity of the battery to turn off the SoundLink while charging or can i use it while it is charging?
Great question! You're free to use the speaker whilst charging, but this will obviously mean the speaker is actively using battery whilst charging so it may take longer to reach 100%. This shouldn't be a problem but it's something to keep in mind. Only charging the speaker when needed is the best approach, but you can still use the speaker whilst charging.
Let me know if you have any other queries!
