The Sony SRS XB22 Bluetooth portable speaker has a simple battery level indicator LED in the rear button / port panel, just to the right of the USB input port, as shown in the pictures that follow. 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, nor exactly how full the battery is at a given time while charging or draining. But it does blink orange when the battery hits close-to-dead. So in this post, we explain how to read this battery indicator LED on the XB22 speaker.
To obtain a more precise reading of battery percentage, see below.
Sony SRS XB22 Battery Indicator: How to Read the Light
1. The Lamp is OFF
The battery lamp is dark in the following situations:
- When you power down the XB22 with no charger connected.
- When the charger IS connected but the battery finished charging to full, as shown next.
- And finally, this light is OFF when the speaker itself is powered ON, but the battery is fuller than critically low. This light is dark as long as the battery does not yet need charging in this case.
2. The Sony SRS XB22 Battery Indicator Flashes Orange
With the charger unplugged, the XB22 powered ON, and the battery having very little energy left, this light starts flashing orange. The meaning here is that the speaker will shorty power off due to a dying battery, and so, you should put it on the charge soon to avoid play interruption.
3. This Lamp Also Works as a Charging Light
This LED also lights steady orange (no blinking) as the XB22 recharges, as we see in the next picture. On this speaker, the light glowing is the only visual way of telling that charging is occurring. But it does not show how far along the recharging is, until it actually goes dark.
Also note that this light should never blink on and off while charging the speaker. If it does, then either your charger is not supplying enough (or any) power, your USB cable is defective, or you have some issue inside the speaker itself.
4. When the Light Goes Dark While Charging, Then Charging is Done
As speaker charging continues, the light keeps glowing, But eventually, battery recharging finishes, and the lamp goes out to show this. It is OFF in this case whether the speaker itself it ON or OFF. Note that the light will go dark too, if you disconnect the charger before the charge cycle has finished.
5. The Sony SRS XB22 Battery Indicator Is Not a Charge Remaining Meter
When unplugged from the charger, this light becomes the battery charge left indicator. Well sort of. I.e. 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. If it flashes, then you can infer that the battery is nearly dead.
Reading Battery Percentage
However, on this speaker, you can get a more precise reading on the percentage of battery charge left.
Just press and hold the Phone-BATT button until the speaker announces the remaining power percent value in a female voice.
