JBL Flip 4 Will Not Charge Or Won’t Hold a Charge

If your JBL Flip 4’s battery is not charging or unexpectedly turns off, it may have a faulty battery. Before replacing the speaker’s battery, check to make sure that the speaker has not been left in abnormal temperatures, such as near a stove or fireplace. Abnormal temperatures can cause the device to lose battery power more quickly than normal.

If your JBL Flip 4 still refuses to charge after replacing the battery, it may have a faulty charging port. To replace the speaker’s charging port, use the JBL Flip 4 USB Port Replacement Guide.
