Wonderboom Battery Level, How to Check

Covers how to check battery level on the Wonderboom Bluetooth speaker, and also, how to know if the battery is degrading over time.





How to Check Wonderboom Battery Level

1. First, Turn ON the Wonderboom 

You won’t be able to read battery charge status unless the speaker is ON.

To turn on the speaker, press and release the Power button, circled in the last picture.

The little lamp in that button should then come on, as shown next, and the speaker should make its startup sound.  If it does not, then the battery could be completely dead.

But as long as there’s some juice in the battery, the speaker should power up.  When it does, move on to the next step.





2. Press and Release the Volume UP and Volume DOWN Buttons to Check Wonderboom Battery Level

Press and release the center areas of the Volume UP and Volume DOWN buttons at the same time.  Find these areas in the picture shown next.

When you press these buttons together, the speaker makes one to four “blunk” sounds to tell you how high the battery level is.  Four blunks means that the battery has between 75 and 100 percent charge.  Three blunks, and the battery has between 50 and 75 percent charge.  Two blunks denotes that you have between 25 and 50 percent charge in the speaker’s battery.  And finally, one blunk means between 0 and 25 percent charge.

Also, when the Wonderboom battery level gets critically low, the Power lamp starts flashing red.

Press these buttons any time the speaker is ON, to check the battery level.  The number of blunks you hear, lets you roughly guess how much time you have left to play the speaker, before it goes dead.  Since a fully charged Wonderboom plays for roughly ten hours.  So four blunks means that the speaker has between 7.5 and 10 hours of play time left before it goes dead.  Three blunks means that it will play for another 5 to 7.5 hours.  Two blunks means between 2.5 and 5 hours of music time left.  And 1 blunk means that you’ll get between 0 and 2.5 more hours of play time.
