How Long the XB 43 Plays on a Full Charge

On a complete charge, the speaker can play for up to twenty-four (24) hours, thanks to its built in lithium ion battery. But when you play it loudly, especially with booming bass, you will indeed see much shorter playing times per recharge.

We see this Bluetooth speaker die in around eight hours when we play at louder volume. So to get the longest playing time per recharge, power saving is useful. Just play it only as loudly as you need to, to hear it well throughout your listening space.

The Play Time Gets Shorter as the Unit Ages

If you own this speaker over a few years, you may notice that the time it plays from a single charge shrinks as the speaker gets older. Why? Because this is normal for devices like this one, that rely on lithium ion batteries.

But by deep cycling the battery now and then, you can slow this charge capacity decrease. So to exercise the XB43, run the battery fully dead, and then recharge it again every three to six months.

Also, we advise that you avoid leaving the speaker connected to a charger once it reaches full charge. Right after the charging lamp goes out, unplug the speaker as soon as you can, to avoid overcharging it and aging the battery early.
