Covers how to check battery life and level on the Sony Extra Bass SRS XB23 Bluetooth speaker, and also, how to know if the battery life is degrading over time.

Sony SRS XB23 Battery Life, Current Charge

1. First, Turn ON the XB23

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. It’s the round button closest to the top of the buttons panel.

The lamp just above the Power button should then light up, as shown next, and the speaker may make a two-beep ding-dong sound if it pairs to a nearby device.  If it does not turn on, then the battery could be completely dead.

But as long as there’s some energy in the battery, the speaker should boot up.  When it does, move on to the next step.

2. Have the XB23 Speak Battery Percentage Full

The BATT button is also on the buttons strip as we see next.  When punch this, the 23 announces the percentage of battery power left as compared to when the battery has full charge.

The announcements made when you press this button are as follows

    • 70% or greater: The speaker says, “Battery fully charged.”
    • 50% or greater: The speaker says, “Battery about 70%.”
    • 20% or greater: The speaker says, “Battery about 50%.”
    • 10% or greater: The speaker says, “Battery about 20%.”
    • Less than 10%: The speaker says, “Please charge.”

3. Look at the CHARGE Lamp on the XB23

Or, you can at at least tell at a glance if the battery is on the verge of going dead by way of the CHARGE lamp. When the battery is not too low, this lamp is dark. But when the speaker is running but has very little charge left, this lamp flashes orange. The next picture shows the lamp location.  It’s also in the buttons panel, just below the Power button.

Sony SRS XB23 Battery Life, Overall Battery Condition

When the speaker is new, and using a USB charger that can supply at least 1.5 amps, the battery charge time is about four (4.0) hours to reach a full charge.

And, the fully charged battery should last for about twelve (12) hours of music time before going dead, when you play it at low to moderate volume levels with the party lights OFF, and the speaker is neither too hot nor too cold.

A sign of a failing battery, is that it goes dead too quickly, or takes too little or too much time to fully recharge. So if you fully charge your speaker, but it repeatedly only plays for under ten hours before dying, its battery may be bad, and unable to hold a full charge anymore.

If the SRS XB23 battery takes longer than six hours to completely recharge, this could also mean a dying battery.  It might mean as well, that the charger you’re using is not strong enough to recharge the speaker in the specified recharge time.

Also, slow charging can happen because your charge cord is too thin.  So for best results, we suggest a high capacity USB cable (one that easily carries at least 2 amps).
