Gives Wonderboom 2 Bluetooth speaker battery level check instructions, and also, how to know if the battery is losing performance over time. When you press the right buttons while the speaker is powered up, it emits one or more sound pulses to tell you how full the battery is, as described below.
Wonderboom 2 Battery Level Check Instructions, Step by Step
1. First, Turn ON the Wonderboom 2
You won’t be able to read battery level unless the speaker is ON.
To turn on the speaker, press and release the Power button, pointed out by the yellow arrow the last picture.
The little lamp in that button should then light up, 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 energy in the battery, the speaker should power up. When it does, move ahead to the next step.
2. Press and Release the Volume UP and Volume DOWN Buttons to Check Wonderboom 2 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. The Volume Up button is located in the center of the plus (+) symbol on the speaker front, and the Volume Down button is found in the middle of the vertical minus (-) symbol, just below the plus symbol.
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 2 battery level gets critically low, the Power lamp starts flashing red, as shown next.
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.
