The Flip 4 Bluetooth speaker has a group of LEDs across its top panel, as shown in the pictures that follow. These display battery status and charging status. In short, the JBL Flip 4 charging indicator lets you see charging progress; how full the battery is at a given time while charging.
How to Read the JBL Flip 4 Charging Indicator Lights
1. All Lamps OFF
When you power down the Flip 4 with no charger connected, no lamps light up, as shown next. The lamps also all show dark when the charger IS connected but the battery finished charging to full.
See our How to Charge JBL Flip 4 Wireless Bluetooth Speakers piece for more details on connecting the USB charge cable.
2. JBL Flip 4 Charging Indicator Shows Battery Recharging Progress
There are five lamps that light in succession as the speaker battery charging advances, as shown in the next picture. The Flip 4 charges when you see one of these lamps blinking white. When the battery fully discharges, the light on the far left blinks white while charging. Then as charging continues, that lamp stops flashing, and assumes a steady white glow. At that point, the next lamp to the right starts blinking white.
Note though, that you may see the first lamp (far left) blink red. This does not mean that charging is proceeding. Instead, it means that the speaker battery is critically low and should be recharged immediately. It only flashes red when the battery is nearly dead and AC power has not yet been connected to the speaker. When you apply adequate USB power, this red flashing light begins blinking white. Remember. This light never flashes red while charging is happening.
3. When All Lamps Light Up Solid, Charging is Finished
As speaker charging continues, more and more of the lamps on the JBL Flip 4 charging indicator light up solid, That is, the flashing LED moves further and further to the right, until that blinking reaches the last of these five lamps.
Battery charging is done when all but the last of the battery status lights light solid. The last one continues to blink for several minutes. Again, you know that charging is occurring if one of the battery charge level lamps is flashing white.
This next picture shows the speaker just before completing a full charge cycle. Note that all the lamps in the battery status meter are glowing. However, the last one continues to blink.
The battery recharge cycle finishes when all battery status gauge lights turn off, as shown next. Thus, the battery is no longer charging when all lamps are OFF. Even with the AC charger still connected, no lamp glows when battery is full.
4. The JBL Flip 4 Charging Indicator Also a Battery Charge Remaining Meter
When unplugged from the charger, what was the charging indicator becomes the battery charge left indicator. The more lights lit, the fuller the battery. The fewer glowing lamps, the less speaker run time left. These lamps show battery status for a brief time after you power up the Flip 4, or whenever you press any of the buttons. To save power, these lamps go dark after some seconds. So to see the battery charge remaining indication once more, just press the volume UP or DOWN buttons to bring the lamps back to life.
The next picture shows a JBL Flip 4, powered ON, with all five lights aglow in its battery status indicator, meaning that the battery is between eighty and one hundred percent charged.
