How Long it Plays for a Full Charge

On a complete charge, the Ultimate Ears Wonderboom 2 speaker can run for up to thirteen (13) hours, when charging a BC1.2 compliant USB adapter.  But when you play it loudly, especially with added bass, you will see somewhat shorter music power.  We’ve seen this mini speaker run dead in around eleven hours when played at louder volumes. So to get the longest charge time from it, power saving is crucial.  Just play it only as loudly as you need to, to hear it well throughout your listening space, and you will see longer play times.

The Charge Time Gets Smaller as the Ultimate Ears Wonderboom 2 Speaker Ages

If you own this BT speaker over a few to five years or more, you may observe that the time it plays from a single charge shrinks as the unit gets older.  This is normal for devices that rely on ion lithium batteries, as this unit does.

But by working the battery every now and then, you can slow this charge reserve fall off.

To exercise the Ultimate Ears Wonderboom 2, run the battery dead and charge it again every three to six months when not in use.

Also, we advise that you not leave the speaker plugged into a charger once it has reached full charge.  Right after the charging lamps completely go out, disconnect the speaker as soon as you can, to avoid overcharging it and degrading the battery.

Finally, when the speaker goes dead, charge it as soon as you can.  Do not leave a dead unit sitting around for very long, as this can shrink the amount of usable power storage in the battery.
