JBL Bluetooth Speaker Not Charging

• Restart your JBL speaker: One of the first steps that you should take when troubleshooting any electronic device is to turn it off, then on. This will vary depending on your specific model of JBL speaker, but typically, you should be able to press and hold the Volume Up and Bluetooth buttons for 10-15 seconds. The speaker should complete a power cycle.
• Update your speaker's software: Sometimes software updates can help resolve issues with how your speaker functions. Check to see if your speaker needs an update through the JBL Portable App.
• Check your charging cable/Power source: Double-check that the power source that you are charging your speaker from is actually powered on, or try a different outlet/charger.
• Ensure that your device is charged for an appropriate amount of time: Make sure that you've charged your speaker for an appointment amount of time to ensure that it is fully charged. JBL recommends at least 2.5 to 5.5 hours.

Think about all the places you take your speaker. It could be that some kind of foreign object has lodged itself inside the charging port of the speaker and is preventing your speaker from charging.

• Inspect the port using a flashlight. It is common for bits of lint or rubbish to get caught. They compress into the back of the port with repeated charges.
  • If your charge port shows signs of burn or corrosion, skip to the Charging Port Defective section.
• Check the fit of your cable. Does the charging plug sit flush with the bottom of the charging port? If not, it should. If it’s askew or there’s a gap where you can still see the metal of the charger, it’s time for a good cleaning.
• If there's debris in the port, give it a thorough cleaning: Use a Q-tip or custom swab, a small soft bristle brush, or canned air/eco-friendly alternative to clear stubborn blockages. Avoid using liquids, as that could lead to water damage within the speaker.

Avoid inserting anything metal into the port, as the metal pins inside are easily damaged. Additionally, inadvertently bridging pins together can cause electrical damage.

If you notice any burns or damage, or if you’ve thoroughly cleaned out all the gunk from the port, or if everything appeared spotless from the beginning, the port might be faulty.

• If your charging cable seems loose when you connect it or have to hold it in a certain position, the port itself may have some loose connections. Your best bet here is to replace the charge port assembly. Be sure to look up the charge port replacement guide for your specific model of phone.
• To truly assess the port’s integrity, you’ll need some magnification or a USB ammeter. A functioning charge port should allow current to flow through it to charge the battery.
• If your charge port is connected to the main motherboard, you’ll need some soldering skills to replace it. Alternatively, you can find someone with the necessary soldering expertise to remove the existing port and install a new one. Otherwise, you’ll be forced to replace the entire motherboard.

Lithium Polymer batteries degrade over time, reducing their capacity to charge quickly. If you have an older Android phone, the issue might be caused by the battery.

• Since JBL does not have a software-based way of testing if the battery is healthy, you'll need to test the health of your speaker's lithium battery with a multimeter. Simply switch your meter to DC and connect the probes to the positive terminal and the negative terminal. The reading should be close to the rated voltage of the battery.
• The normal lifespan of a Lithium Polymer battery is between 500 to 1,000 charge cycles, otherwise around two to three years.
• If your speaker's battery is up there in age or the voltage reading is zero, then it might be time to replace it. Be sure to follow the replacement guide for your specific model of JBL speaker.

The main logic board of your speaker is responsible for most of its functionality. If any of the small components on the board have failed or become damaged, it’s reasonable to assume that this is the cause, assuming nothing else on this page has worked.

• Check for signs of a board issue, such as burned or cracked components, liquid residue, corrosion, or bending. If you notice any liquid, refer to our Electronics Water Damage Wiki. Although initially designed for iPhones, the iPhone Liquid Damage guide offers valuable information that can be beneficial for your phone as well.
• Replacing the logic board is often the most practical solution for a DIYer who has a faulty board.
• While repairing the board itself may be challenging, it is possible. However, this requires specialized tools and micro-soldering expertise. If you’re interested in learning micro-soldering, here are some excellent resources for reading and watching that can help you get started.
