The JBL Go has a single LED near the top of the front panel. This displays battery status. It shows whether it’s draining or charging, or whether it’s critically low or not when discharging. But this light does not read out charging progress. Nor does it show battery percentage or how full the battery is. Nor does it show how much power remains in the battery when discharging. But it does change color when the battery reaches near-dead state. So in this piece, we describe how to read the JBL Go Battery Indicator lamp.
JBL Go Battery Indicator: How to Read the Light
1. The Battery Indicator Lamp is OFF
When you power down the Go, this lamp goes dark when the battery is not charging. The lamp is also dark when the charger IS present, but charging is complete.
2. JBL Go Battery Indicator: Shows Battery Recharging Progress
The status lamp lights up red (no flashing) while the speaker charges. On this speaker, the glowing light is the only visual indication that charging is going on. But it does not display how far along the charging is.
Note that this lamp blinks red when the battery is critically low while the speaker is running on battery power. This indicates that a recharge is necessary. But when you apply USB power, this red flashing light turns to a solid red. Also note that this light never flashes red while charging is occurring.
3. When the Light Goes Out While Charging, Then Charging is Complete
As speaker charging continues, the light keeps glowing red. But eventually, battery finishes charging. And then the lamp goes out, or turns blue to show this. It turn off when the speaker is OFF, and turns blue when it is ON.
4. The JBL Go Battery Indicator: It Is Not Much of a Charge Remaining Meter
When unplugged from the charger, what was the Battery Indicator becomes the charge left indicator. Well sort of. If it glows blue, then the battery has some amount of play time left, although you cannot tell how much. Note though that this light blinks when the speaker has no pairing session active.
This light indeed gives some indication about battery status when not charging. But only when the battery hits very low levels. Then, it starts flashing red, as mentioned above.
