Perform a Hard Reset on the JBL Charge 4
If the JBL Charge 4 speaker is experiencing a software issue, a hard reset may help resolve the issue. This procedure will erase all previously paired devices and sound modes, and return the speaker to its default settings.
- To perform a hard reset, follow these steps:
- Press the power button to turn on the speaker.
- Press and hold the Bluetooth and Volume Up (+) buttons simultaneously.
- Release the buttons once the speaker turns off.
- Press the power button to turn the speaker back on.
- Attempt to charge the speaker and check if it is working.
Use a Different Wall and USB Charger
JBL speakers come with their own charger, but if you’ve lost it or are using a third-party one, this could be the root of the problem. Lower-quality chargers may not provide enough voltage to charge the speaker, and over time, even the original JBL charger can become damaged or stop working.
To address this issue, try using a different (preferably new) charger and see if it resolves the problem. You could borrow one from a friend or try a charger at an electronic repair shop before purchasing a new one. The wall charger should have a power output of 5V/1.0A, which is the maximum charging speed for the JBL Charge 4.
If the wall charger has a lower power output, it may not charge the speaker at all or do so very slowly. Conversely, if the wall charger has a higher output than 5V/1.0A, it could damage the battery or prevent the speaker from charging altogether.
Use a Different USB Charger
Aside from the wall charger, the USB charging cable could also be faulty. To test this, try using a different charging cable and see if the speaker charges. Short and thick cables tend to be more durable, while long and thin cables can cause voltage drop.
You can also test the USB cable by using it to charge a different device, such as an Android phone. If the phone charges successfully, then the speaker is likely the issue, but if the phone does not charge, then the cable is likely the problem. You could also try using your phone’s USB charger to see if it works with the JBL Charge 4 speaker.
Clean the Charging Port
The JBL Charge 4 speaker is water-resistant, but if you’ve taken it outside for outdoor activities, dust and water may accumulate in the charging port.
To clean the port, use a small soft brush or blow out any dust with a toothpick or similar tool. Be careful not to damage the port while cleaning.
After cleaning, use a flashlight to inspect the port for any remaining dirt. If there is no dirt, try charging the speaker and see if the issue is resolved.
Defective Battery
JBL speakers come with a rechargeable lithium battery that has a limited number of charging cycles, typically around 500. A charging cycle is completed when the speaker is charged from 0-100% and then back to 0%.
With daily use, it can take up to 2-3 years to complete all 500 charging cycles. If you’ve had the speaker for longer than this, the battery may be the problem and will need to be replaced.
Defective Circuit Board
If the JBL Charge 4 speaker has been submerged in water for an extended period of time or has been dropped, the circuit board could be damaged. In this case, there is no trick to repair the circuit board and it will need to be sent to a local electronic repair shop for fixing.
By following the tips outlined in this article, you’ll have a good starting point for troubleshooting your speaker and getting it back up and running. If none of the fixes work, it may be necessary to take the speaker to an electronic repair shop for further assistance.
