JBL Bluetooth Speaker Not Charging

• Restart your JBL speaker: One of the first steps when troubleshooting any electronic device is to turn it off, then back on. This will vary by your JBL speaker model, but typically, you should 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 whether your speaker needs an update using the JBL Portable App.
• Check your charging cable/Power source: Double-check that the power source you're using to charge your speaker is powered on, or try a different outlet/charger.
• Ensure that your device is charged for an appropriate amount of time: Make sure you've charged your speaker for an appropriate amount of time to ensure 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 a foreign object has lodged itself in the speaker's charging port, preventing it 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 charger's metal, 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 they could cause water damage to 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 feels loose when you connect it or if you have to hold it in a certain position, the port itself may have 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 phone model.
• 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.

• Since JBL does not have a software-based way to test whether the battery is healthy, you'll need to test your speaker's lithium battery with a multimeter. Switch your meter to DC and connect the probes to the positive and negative terminals. The reading should be close to the battery's rated voltage.
• The normal lifespan of a Lithium Polymer battery is between 500 and 1,000 charge cycles, or around two to three years.
• If your speaker's battery is old or the voltage reading is zero, 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 been damaged, it's reasonable to assume this is the cause, unless 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 originally designed for iPhones, the iPhone Liquid Damage guide offers valuable information that can benefit 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 to read and watch to help you get started.
