Covers how to check the battery on the tiny Sony Extra Bass SRS XB01 personal Bluetooth speaker, and also, how to know if the battery’s lasting power is decreasing as time passes.
How to Check Sony SRS XB01 Battery, Current Charge
1. First, Turn ON the XB01
You won’t be able to read battery charge status unless the speaker is ON.
To turn on the unit, press and release the Power button, pointed at by the yellow arrow in the last picture.
The small lamp on the front top left corner of the grill should then light up, as shown next. Plus, the speaker may make a two-beep sound if it pairs to a nearby device. If it does not boot up, then the battery could be completely depleted.
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 this Sony Mini Speaker
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 SRS XB01 Battery, Overall Condition
When the speaker is new, and using a full power USB charger, the battery charge time is about three (3) hours to reach a full charge.
And, the fully recharged battery should last for around six (6) hours of play time before going dead, when you play the speaker at moderate volume levels. It lasts around three (3) hours if you play this unit at maximum volume.
A sign of a failing battery, is that it runs dead too fast. Or, it takes too little or too much time to charge all the way. So if you repeatedly charge your speaker to full, but it only plays for under three hours before shutting off, then its battery is likely bad. I.e. It cannot hold a full charge anymore.
If the SRS XB01 battery takes longer than four hours to completely recharge, this could also mean a fading battery. It might mean also, that the charger you’re using is not strong enough to recharge the speaker in the specified charge time of 2 hours, or that something is wrong with the speaker itself.
Also, slow charging can happen because your charge cord is too thin. So for best results, we encourage you to use at least a medium-current USB cable (one that easily carries 1.0 amps).
