Sony SRS XB13 Battery Indicator, How to Read

The Sony SRS XB13 Extra Bass Bluetooth speaker has a battery level indicator LED near the bottom of the button panel, as shown in the following pictures.  This displays battery status. E.g. Whether it’s draining or charging, or whether it’s critically low or not when discharging.  But it neither reads out charging progress, or how full the battery is at a given time while charging or draining. But it does flash when the battery reaches near-dead state. In this post, we describe how to read this battery indicator lamp on the XB13.

How to Read the Sony SRS XB13 Battery Indicator Light

1. The Light is OFF 

The battery level indicator (CHARGE) lamp is dark in the following situations:

  1. When you power down the XB 13 with no charger connected.
  2. When the charger IS connected but the battery finished charging to full, as shown next.  This lamp is OFF in this situation.
  3. And finally, the CHARGE light is OFF when the speaker itself is powered ON, but the battery is fuller than critically low, and the speaker is not charging. The lamp is dark as long as the battery does not yet need charging in this case.

2. The Sony XB13 Battery Indicator Light Flashes Orange

With the charger not connected, the XB13 powered ON, and the battery having very little energy left, the CHARGE light starts blinking orange.  This means that the speaker will soon shut off due to a dead battery and that you should put it on the charge soon to avoid interruption of play.

3. Sony SRS XB13 Battery Indicator Lamp Doubles as a Charging Light

The CHARGE lamp glows orange (no flashing) as the XB13 recharges, as shown in the next picture.   On this speaker, this glowing light is the only visual means of knowing that charging is going on.  But it does not display how far along the charging is.

Also note that this light should never flash during charging.  If it does, then either your charger is not functioning well, your USB cable is bad, or some problems exists inside the speaker.

4. When the Battery Indicator Goes Out While Charging, Then Charging is Done

As speaker charging continues, the indicator keeps glowing,  But eventually, battery recharging finishes, and the lamp goes out to show this.  It turns off when the speaker is not ON, and stays OFF when the XB13 is ON.

5. The Sony SRS XB13 Battery Indicator Is Not Much of a Charge Remaining Meter

When unplugged from the charger, what was the charging indicator becomes the battery charge left indicator.  Well sort of.  If it is dark when the speaker is ON, then the battery has some amount of play time left, although you cannot tell how much.
