Sony SRS XB13 Battery Life

Sony SRS XB13 front panel buttons.

Covers how to check battery life and level on the Sony Extra Bass SRS XB13 Bluetooth speaker, and also, how to know if the battery life is degrading over time.

Sony SRS XB13 Battery Life, Current Charge

1. First, Turn ON the XB13

You won’t be able to read battery charge status unless the speaker is ON.

To turn on the speaker, press and release the Power button, pointed at by the green arrow in the last picture.

The little lamp on the front of the speaker should then light up, as shown next, and the speaker may make a two-beep 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 power up. When it does, move on to the next step.

2. Look at the CHARGE Lamp on the XB13

Note that this speaker has no battery gauge to let you know exactly how much charge is left. But you can at least, tell if the battery is on the verge of going dead by way of the CHARGE lamp. When the battery is not super 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 just below and to the left of the Power button.

Sony SRS XB13 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 full charge.

And, the fully charged battery should last for around sixteen (16) hours of play time before going dead, when played at low to moderate volume levels, and the speaker is neither too hot nor too cold.

A sign of a bad battery, is that it goes dead too fast, or takes too little or too much time to fully charge. 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 XB13 battery takes longer than six hours to completely recharge, this could also mean a failing battery. It might mean also, 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 recommend a full-current USB cable (one that easily carries at least 1 amp).
