Sony Cube Speaker Charging Time: How Long to Fully Recharge

According to the specs for this speaker the time it takes to charge the cube Bluetooth speaker is four (4) hours, using a 5 volt, 1.5 amp, 7.5 watt charger. Or, it takes eight (8) hours if using a 5 volt, 500 milliamp, 2.5 watt charger.

How Long it Plays Per Full Charge

On a complete charge, this cube style Sony speaker can play for up to twelve (12) hours, due to its 7.4 volt, lithium ion battery. But when you play it loudly, especially with lots of bass, you will see abbreviated playing time.

We’ve seen this Bluetooth speaker run dead in around seven hours when played 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 Charging Time Gets Smaller as the Cube 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 degradation.

To exercise the cube, 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.
