How Long it Plays Per Full Charge

On a complete charge, the SRS XB01 Sony speaker can play for up to six (6) hours, due to its lithium ion battery. But when you play it loudly, especially with lots of bass, you will see abbreviated playing time. We see this Bluetooth speaker run dead in around three hours when we play at louder volumes.

So to get the longest charge time from it, power saving is critical. Just play it only as loudly as you need to, to hear it well throughout your listening space.

The Charge Time Gets Smaller as the XB01 Ages

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

But by fully cycling the battery periodically, you can slow this charge capacity reduction.

To exercise the XB01, run the battery fully dead, and then recharge it again every three to six months when not in use.

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