Covers how to check battery life and level on the tiny Sony personal cube Bluetooth speaker, and also, how to know if the battery’s lasting power is shortening over time.
How to Check Battery Life on the Sony Cube Speaker, Current Charge
1. First, Turn ON the Cube
You won’t be able to infer battery charge status unless the speaker is ON first.
To turn on the unit, press and release the Power-Pairing button, pointed at by the yellow arrow in the last picture.
The small lamp on the front bottom center of the grill should then light up white, as shown next. Plus, the speaker makes a two-beep, low-high sound. If it does not boot, then the battery could be completely run down.
But as long as there’s some energy in the battery, the speaker should power up. So when it does, go ahead with the next step.
2. Look at the CHARGE Lamp on the Cube
Note that this speaker has no battery meter to read out exactly how much charge still remains. But you can at least tell if the battery is on the verge of going dead by way of the CHARGE lamp. E.g. When the battery is not critically low, this lamp is dark. But when the speaker has very little charge left, this lamp flashes orange. The next picture shows the lamp location. It’s on the front, near the top right corner of the speaker grill.
How to Check Sony Cube Speaker Battery Life, Overall Battery Condition
When the speaker is new, and using a full power USB charger, the battery charge time is about four and a half (4.5) hours to reach a complete recharge.
And, the fully charged battery should last for around twelve (12) hours of play time before going dead, when you run the speaker at moderate volume. It lasts much less time if you play it at maximum volume.
A sign of a failing battery, is that it runs dead too quickly. Or, it takes too little or too much time to charge all the way. So if you repeatedly recharge your cube to full, but it only plays for under six hours before shutting off, even at low volumes, then its battery is at end-of-life. I.e. It cannot hold a full charge anymore.
If the cube battery takes longer than five hours to completely recharge, this could also mean a failing battery. Long recharge times might also indicate that the charger you have is not strong enough to fully charge the speaker in the specified charge time of 2 hours. Then too, something could be wrong with the speaker itself. Be sure to use a charger that delivers 5 volts at 1.5 amps for fastest charging, and try several different chargers.
Also, slow charging can happen because your charging cable is too thin. So for best results, we suggest you use at least a high-current USB cable (one that easily carries 2.0 amps).
