How Long the XP 500 Plays on a Full Charge

On a complete charge, the speaker can play for up to twenty (20) 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 charge cycle.

We see this Bluetooth speaker die in around ten hours when we play at louder volume and use the built-in party lights. 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 Sony XP 500 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. 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 XP 500, run the battery all the way dead, and then recharge it again every three to six months.

Also, we advise that you avoid leaving the speaker connected to AC power once it reaches full charge. Thus, right after the charging lamp goes out, unplug the speaker as soon as you can. Why? Because this avoids possible overcharging it and aging the battery prematurely.
