A Bluetooth speaker is everyone’s favorite travel companion.

It is important to know how to fix a Bluetooth speaker that won’t charge, considering this is one of the common issues that Bluetooth speaker owners face from time to time.

As a music/sound enthusiast.

A top disappointment that you can face or be confronted with is the inability to charge your device (Bluetooth speaker) ahead of a long trip or when the charge gets depleted.

This guide discusses common issues that may prevent your speaker from charging and how to fix them.

What Are The Possible Causes For Your Bluetooth Speaker Not Charging?

There are various reasons why Bluetooth speakers may fail to charge, no matter how much you try or the number of attempts you make to correct this issue or make it work.

The first step towards fixing a faulty Bluetooth speaker (a speaker that doesn’t charge) is your ability to identify the issue appropriately.

The main reasons why a Bluetooth speaker may stop charging can be classified under software and hardware problems.

Software Problems

Software problems are known or identified as disruptions that may result from software bugs.

Software-related issues can only be fixed with the installation of software updates.

Hardware Problems

On the other hand, hardware problems/disruptions may arise due to a faulty charging circuit, bad battery, damaged cable, cracked/broken solder joint, and faulty charging port.

How Would You Identify What’s Wrong With Your Bluetooth Speaker?

Identifying the issues with your Bluetooth speaker requires a lot of time and patience, considering the need to perform a series of checks to finally pick out the problem.

Considering there are a series of hardware issues that could prevent your device from charging.

We recommend that you begin the troubleshooting and repair process by checking/verifying if the issue is software-related.

Software Update

Since software bugs could prevent or stop your device from charging, the most ideal thing is to start your detection & repair exercise from this point.

To fix possible bugs or issues with the software, ensure you download and install the latest software on your device.

Device Reset

Once you have installed the latest software update on your Bluetooth speaker, the next step is to perform a reset.

Go through the user’s manual to see how you can perform a reset on your device.

Next Steps

If the software update & the reset do not fix the problem.

You may have to inspect/check your device for possible hardware problems.


  • Screwdriver
  • Magnifying glass
  • Portable soldering iron
  • Hairdryer
  • Clean rag


The cost of repair depends on the broken/damaged component(s).

For instance, a new cable is less expensive or more affordable than a new battery.

Hence, the severity of the issue determines the cost of the repair.


The duration of the repair process depends majorly on how soon you can pick out the exact issue with your Bluetooth speaker.

Once you are able to identify the problem (irrespective of the affected component).

On average, the repair process should be finalized or completed in about an hour or two (2).

Fixes To Possible Issues of How to Fix a Bluetooth Speaker That Won’t Charge?

Replacing The USB Cable

A faulty USB cable could prevent your speaker from charging.

Before you proceed to remove the cover of your device to access the internal components and check for possible faults, it is advised you start with this check.

To detect if the charging cable is the issue, you can charge another device with your Bluetooth speaker’s USB cable.

For instance, charge your smartphone with it.

If the USB cable doesn’t charge your smartphone, you may agree that it is the culprit.

Hence, you may need to consider a replacement or upgrade.

However, if the USB cable charges another device.

You may have to extend your search to uncover the main issue.

Battery Replacement

This may be the last approach on your list.

It is the most expensive repair/replacement technique to consider as you work towards bringing your Bluetooth speaker back to life or making it charge again.

Your device’s Bluetooth battery is not built to last a lifetime.

After some time, which may possibly run to years, the battery becomes weak.

During this period, the efficiency or working-life drops significantly.

In the process, charging is restricted since the battery can’t take in any power.

During this time, you will be confronted with two choices to pick from.

You may decide to replace the Bluetooth speaker completely (picking up a new device) or replace the weak/faulty battery.

Considering the two options, replacing the damaged battery is more economical, especially if you do not have a sufficient budget to pick up a new device.

Replacing Old/Damaged Battery

  • To replace the battery with a new one, you will have to take out the old one. Reposition your device (ensure the bottom faces the sky), and remove/detach the anti-slip mat.
  • Once the mat is off, this exposes the screws holding the speaker’s cover in place. Take the screws out.
  • For easy removal of the battery, you make us of your soldering iron. The role of the soldering iron is to deliver sufficient heat to the maintained screw for easier and uncomplicated detachment of the battery from the audio motherboard.
  • Here is where your electronic device knowledge and the use of a soldering iron come to play. You will be required to join new cables together using a soldering iron. Also, you will have to connect the correct plugs and attach the cable (just an end) to the motherboard’s anode and cathode area.
  • Once the necessary connections have been made, you will then proceed to hold them in place with the aid of double-sided tape. Ensure the two ends of the new battery are also covered with this tape.
  • The new battery will then be positioned on the motherboard. Afterwards, place the cover rightly and reattach the screw (s).
  • Reattach the anti-slip mat to its position using an adhesive, preferably double-sided tape, to complete the process.

Charging Port Replacement

When the charging port is bad, there is no way your Bluetooth speaker will charge.

This part of your device is exposed, making it highly susceptible to dirt and other contaminants.

In addition, the charging port may become damaged due to frequent forceful removal of the USB cable after a full charge.

In a situation where the charging port is compromised by contaminants.

Especially when there is a load of debris hanging inside the port.

This may prevent the USB charging cable from sitting well or appropriately when plugged into the charging port.

Check the charging port for dirt residue.

If there is, you can flush out the debris with the aid of a thin pin or needle.

If the charging port is completely free from debris, you may have to check the connector pin.

If you notice any sign of bend (which happens due to constant forceful removal of the charging cable).

You have no other option than to replace the charging port with a new one.

Fixing A Broken Solder Joint

To fix a broken solder joint, you will also have to remove the device’s cover to gain access to the internal components.

Earlier in this section (battery replacement), we discussed how you can conveniently access the Bluetooth speaker’s internal components.

If it appears that the USB charging socket is not tight, unfastened, or moving around freely.

This is a strong indication that the solder joint is wrecked.

First, you will have to identify the solder joint that has gone bad.

Locating the cracked solder joint is easier with the aid of a magnifying glass.

While at it, ensure you take your time to prevent any damage to the seals. Especially if you own a waterproof device.

Once you have successfully laid your hand on the broken solder joint, you will have to hold it back in place or repair it using a soldering iron.

Make sure the soldering iron tip is free from dirt, particles, or contaminants for best results.

In addition to that, use fresh/clean solder only.

Immediately after the process is complete, ensure you confirm if everything is in place before attaching the cover back.

Charging Circuit Replacement

What the charging circuit does is transfer power to your device’s battery.

When this component goes bad, there is no way your Bluetooth speaker will get the power required to get the battery charged.

We can simply say that the battery and the charging circuit share a cordial relationship.

Once the circuit goes bad or becomes terrible, the battery becomes unusable.

Other Potential Problems And Fixes

Fast Charge Depletion

In some cases, you may experience an unexplainable or abnormal battery depletion.

This is when your Bluetooth speaker finds it hard to retain charge as expected or in the usual way.

For instance, you may experience that a speaker that usually lasts for up to 15 hours of use hardly performs for 2 hours.

This issue is commonly associated with the battery.

It is more rampant or common with speakers that have been in use for about 5 years due to depletion in the battery’s charge cycles.

Once you notice that your battery depletes at an unbelievable rate after full charge, you may have to consider a replacement.

Not Fully Charging

Asides from the inability of the Bluetooth speaker to retain/hold its charge.

It may also fail to attain full charge.

This issue is mainly associated with a faulty charging port due to a bent/displaced mental connector, resulting from forceful removal of the charging cable over time.

Also, you may experience this issue when the USB charging cable cannot fit into the charging port appropriately.

If there is a loose connection between the two components (the USB cable and the USB port).

The cable can easily slide out, resulting in a disruption in the charging process.

Alternative Charging Methods

If you can’t find a way around this issue after numerous attempts.

You may have to consider some other means or techniques to charge your Bluetooth speaker.

The following are some of the available/common ways to keep your device going:

01. Wireless Charging

If your device supports this feature, you may consider going through this route to keep your device charged.

02. Power Bank

This is one of the ways you can supplement your battery in a situation where the charge depletes faster than usual.

03. Mobile Charger

This is an approach you can consider if your cable is faulty prior to picking up a replacement.

The good thing is that this type of charger is affordable and also does its job well.

04. Smartphone

If you own a smartphone that supports the charging of other devices.

You can use it to keep your Bluetooth speaker charged pending the time you identify the issue and get it fixed.
