JBL Charge 4 Not Charging: Causes & How to Fix

Not every problem will require you to replace a part of the JBL speaker but you should be prepared for anything. If you’ve been dealing with this problem for a while before the speaker completely stops charging then something might be due for a replacement.

1. Change the Charging Cable

The first thing to check is the charging cable. Charging cable might have to be replaced after a few months of use or in some cases years. Depending on your level of maintenance, the cord could be bent and become defective whenever you plug in the speaker to charge.

Unlike older models, the JBL Charge 4 makes use of a type-C USB cable which means you won’t notice any wobbling that should indicate the USB cord has to be replaced. If you notice that the cord doesn’t make a snug fit as it does before, it might not be able to properly charge the speaker. Try using a new cord to see if it solves the problem. If not, you can move on to other fixes.

2. Change the Charger

A defective charger could also cause your JBL Charge 4 charging problems. The charger could be defective due to some internal fault that is unrelated to the speaker. This could be due to a damaged internal board. You might want to try the charger on another device and try a new charger on the speaker. This should tell you if the speaker is working fine.

Since the JBL Charge 4 uses a USB-C charger, you could switch with that of your Android phone. If everything works fine, then you will have to purchase a new charger.

3. Check the Charging Port

Sometimes the fix will only require proper maintenance of your speaker. Designed for outdoor entertainment, the speaker could easily gather dust and grime from being kept outdoors while you relax by the pool or enjoy the view of the beach. If you notice that the charger does not fit properly or that the speaker won’t charge, you might want to check if the port is clean.

Cleaning the port will require a small brush, earbuds, or toothpick. You should also inspect the charging port to see if any of the connector pins are bent or damaged. This could happen anytime you try to force in the USB cable to make a proper connection. If you notice any damage on the connector pins, then you will have to replace the charging port.

4. Reset the Speaker

The charging problem could be due to a glitch or a bug in the code of the Bluetooth speaker. To solve this, you will have to perform a factory reset. The factory reset will wipe out the current data on the Bluetooth speaker and return it to its default or factory settings. This fix also helps when experiencing Bluetooth problems.

To perform a factory reset, ensure the JBL charge 4 is turned on. Press and hold the play and volume buttons for up to 5 seconds. After that, turn on the device again and try to charge it. If the problem was due to a bug, the speaker should be able to charge.

5. Replace the Battery

If you have an older speaker of more than a few years, then you could be dealing with a defective battery. There are several reasons why the battery could be defective. First, it could be due to overcharging. This happens when you leave the battery charging for a long while even after it has reached its full charge capacity.

While mobile phones come with safety features that prevent the battery from drawing any power when it is fully charged, it won’t always be the same for your JBL Charge 4 such that over-charging could weaken the battery’s ability to hold a charge which will lead to charging issues.

Another reason could be over-discharging. It never helps to run your battery down completely and if you do this continuously, it will be difficult for the battery to be boosted with a charger.

It could also be due to an aged battery. The JBL charge 4 runs on a 7500mAh Li-ion rechargeable battery with up to 30 hours of runtime. While this is great for most music lovers, the battery can only last several hundred charging cycles. After many months of use, the battery will no longer be able to hold a charge or last as long as it did when it was newly purchased. At this point, the battery will have to be replaced.

Several things could shorten the lifespan of the battery. Exposure to extreme heat or cold is a big problem. In addition, high and low temperatures will make it difficult for the battery to charge. Lithium-ion batteries have a charging range of 32°F to 113°F (0°C to 45°C). Anything above or below this and the battery will be unable to hold a charge.

Final Thoughts

In most cases, you’d be likely dealing with a defective charging cable, charger, or a damaged charging port. If you JBL Charge 4 has been with you for about 2 or more years, you might want to start thinking about a battery change. Before that, you should consider performing a factory reset to see if it helps.
