How to tell if Sony Cube Speaker personal Bluetooth speaker is charging? This little yet powerful speaker has an orange LED light on the back panel, on the bottom edge of the unit, as shown in the following picture. This CHARGE light flashes orange when the battery is nearly dead. So it tells battery level (to a degree). When the speaker is not on the charge and this lamp blinks, it means to CHARGE the speaker because the battery will soon run out. But also, to see if the cube is charging, read this lamp as well. We explain how to interpret its signals next.

- Connected and working power cable is present.
- The CHARGE lamp glows steadily.

How to Tell if the Sony Cube Speaker is Charging, Detailed Discussion
Connect your Cube to USB Power
Of course, you can tell for sure that the speaker is NOT charging when no power cord connected to it. 🙂
Check that the CHARGE LED is Glowing Solid Orange
When the speaker is OFF, you can tell if the Sony Cube Speaker is charging if this light glows steady orange. This continuous glow occurs while recharging, when the speaker is either ON, connected to a source device, or, OFF. When no charger is present, this light blinks when the battery has about run out of power.
If the CHARGE lamp flashes when the power cord is attached, then the speaker is likely NOT charging due to some power issue. So you should check that your USB cable, adapter charger, and electricity source are in working order. Try a new adapter or wire that you are certain is good. You want this light glowing solid to know for sure that the cube is charging.
Additionally, the button panel on the top may warm slightly as the speaker charges. Moreover, most charger adapters you run it with will also heat a little. This heating is a great indicator to tell if the speaker is indeed charging.
As charging advances toward completion, the CHARGE LED continues glowing. But unlike some of the higher end wireless speakers, the cube gives no reading of just how far along its recharging is, just that the recharging is still in progress.
When the CHARGE LED Goes Out, Charging is Done
The battery charge cycle is finished when the CHARGE LED goes dark.
Even with the charger cord still supplying power, and when the XB11 is OFF or ON, the CHARGE lamp stops glowing when the internal battery is full. We see this in the last picture above. The speaker indeed no longer recharges when the battery reaches full charge condition and this light shuts off.
Finally, Unplug the Sony Cube Speaker and Turn it On
With the USB cable disconnected, we cannot know just by reading the CHARGE or Status LEDs, just how much the cube actually recharged, only that it did charge some. It probably did charge all the way though, as long as we waited until the CHARGE lamp stopped glowing before disconnecting the charger. Note that if this lamp does not flash when you next turn on the speaker, then the battery likely did charge.
