The most common complications which can prevent your Bluetooth speaker from charging include:

  • Before tearing apart your device, try with basics, a simple Bluetooth speaker factory reset can fix most of the “technical problems”. So, go ahead and reset your speaker & see if it resolves the charging issue.
  • The problem can arise due to a bad solder joint on the USB port, for which you’ll have to take apart your device and fix it.
  • The third reason could be the battery, sometimes it’s not the charger or the port but the battery which needs replacement.
  • Lastly, the problem can occur due to a faulty charging cable, usually, multiple devices come with common charging cables now, so try another cable available at your place or borrow it from your friend, and it should fix your Bluetooth speaker’s not charging problem.

Here are these steps explained in detail:

1. Solder Joint Not Working

We consider the Solder joint as the first main reason why your Bluetooth speaker is not charging. Before taking a look at the main steps, we will like to mention the brands on which this procedure works. You can repair the JBL and Aqua sports speakers through this process, but it also works on Bose, UE, Sony, Beats, and other similar manufacturers.

In the first step, you have to open your portable Bluetooth speaker. The purpose is to determine if there is an easy or basic fix or not. In most cases, the USB charging socket is loose or does not fit the cable properly. It means that the solder joint is either cracked or broken and needs re-soldering.

People mostly get frustrated while opening up the speaker because it is a tricky part. But, once you know the minor details, it would be easier for you. You have to open the hidden screws placed under stickers, sound grills, or plugs. After removing all the screws, you can find the fault by using a magnifier. For example, the micro USB port was loose, or you found a bad solder joint. Additionally, if your portable speaker is waterproof, then do this step precisely to avoid damage.

The next step is soldering up the USB charging plug. Locate the USB port first to perform this task. At this spot, try to use a clean tip and dob of solder for soldering. Quickly touch the cracked solder to melt it again. If the soldering tip is large, you can file the tip down to get a nice solder tip. Once you’re done with resoldering positive and negative terminals, test the charge circuit to check whether it is working or not.

2. Low Voltage Lithium-ion Battery

The wireless Bluetooth speakers are equipped with a rechargeable battery. Sometimes, the issue is not in the charger or port but in the battery because your speakers are not charging. This problem usually arises in old Bluetooth speakers. To fix the low-voltage lithium-ion battery, you need to replace it with a new one. This repair can be done by finding a new battery of a similar size to the older one. We have mentioned lithium-ion batteries because many Bluetooth speakers come with this battery in today’s market.

3. Fault in Micro USB Cable

In most cases, when the micro USB cable stops working if you see that the wire and cable are still intact then it means that the USB connector is broken. In this condition, you have to explore the connectors to see if they connector is loose or not. Once you get to know the problem with the connector, you need to buy a replacement connector kit. This kit includes plugs, placement sockets, and tails. It is easily available in the market in different colors and lengths.

However, the second case is when this procedure doesn’t work. It is a rare case that your cable or wire is not working. You have to purchase a new cable or wire, which is not so expensive in this situation. If you don’t want to, you can also replace it by attaching the connector with a new wire.

4. Replace The Charging Port

A broken charging port is another cause of charging issues for Bluetooth speakers. It will be sufficient justification for the charging cable to not make proper contact if we have additionally pressed the USB port’s pins.

Your speaker’s inside, which contains its electrical components, must be accessed. Remove the previous charging port as well. To do this, find the charging port from the outside and make sure the replacement you bought is the right one. The only thing left to do is to weld them into place.

5. Clean The Charging Port Contacts

Our gadgets’ charging ports are a magnet for dust and dirt particles, especially when we leave them on a shelf or table surface for an extended period of time at home. Charging ports are never covered since so few manufacturers do so (unless it is a water-proof Bluetooth speaker). Our speaker cannot charge correctly due to the dirt coating.

Products for maintaining computer equipment, like Air-in-a-can, make this chore incredibly simple. This bottle of compressed air cleans the debris from our charging ports.

To make our charging port sparkle, we first remove the most obvious dust particles before thoroughly cleaning the contacts with a brush and some alcohol. Continue to the following step if all of this cleaning doesn’t assist to fix your Bluetooth speaker.

6. Replace The Charging Circuit

In a broader sense, the charging circuit is in charge of all our device’s charging-related operations. This step will provide you with the most conclusive solution if you are trying to figure out how to fix a Bluetooth speaker that won’t charge and you haven’t had any luck thus far.

The charging circuit includes the PCB that is attached to the battery. This component needs to be replaced, and then the charging issue should be resolved.

How To Change The Battery of Bluetooth Speaker

  • Look for the screws holding the case on your battery as you turn it over with the bottom facing up. Normally, these screws are concealed by an adhesive label or a small rubber pad that frequently serves as an anti-slip rubber grip, making them invisible.
  • In order to reach the interior of your Bluetooth speaker, remove the screws.
  • The battery will be visible as a soft material-coated, semi-flexible tablet (such as laminated paper or plastic). Sometimes it has a cylindrical shape as well. Find the cables that attach the battery to the motherboard of the gadget.
  • Heat the battery terminals with a soldering iron until the solder melts. Until you can take out the defective battery, proceed with caution. (Cut the cables if you determine that their length is adequate and that the terminals can be reused or soldered directly to the new battery.)
  • With the soldering iron, warm up the new battery’s terminals a little before adding a generous amount of solder and attaching the cables.
  • Reinstall the screws after repositioning each component inside the speaker.

How To Fix Bluetooth Speaker That Won’t Charge Completely

The issue with some Bluetooth speakers may not be that they don’t support charging or that they can’t sustain it for a long time, but rather that they never fully charge no matter how long they are plugged into an electrical outlet.

The good news is that all of the solutions we have listed for fixing a Bluetooth speaker that won’t charge apply equally to resolving this issue.

Some of the main reasons why your gadget prevents the battery from being fully charged include:

  • Obstructed by dust or debris charging port
  • Bent micro USB cable connectors
  • Faulty USB cord
  • Loose charging port

Other Things To Consider

Once you are done fixing your problem, it is important to take good care of your favorite speakers to resist the faults. In this section, we will like to mention the things related to charging, that you need to consider while using a portable Bluetooth speaker. Charging duration typically varies depending upon different situations of use of the battery. Always charge your Bluetooth speaker in ambient temperature conditions, for example, between 41 to 95 degrees Fahrenheit.

The Speakers will get warm during or after charging. This is not a signal of malfunction. So don’t unplug the charger before the device gets fully charged. Even if you don’t use your Bluetooth speakers for a long time, charge the battery to its fullest capacity at least once every six months. Doing this can maintain the better performance of your portable Bluetooth speakers.

It is a fact that if you don’t use your speakers for a long time, then it may take a long time to charge the battery. This is because it is always preferred to use your gadgets often. It is necessary to keep those in good condition and increase their lifetime, especially the ones with charging batteries.

Try your best to avoid external exposures. The external pressures include extreme temperature conditions, direct exposure to sunlight or ultraviolet rays, high moisture content, sand, mechanical shocks, or dust particles. Never leave your Bluetooth speakers in your car if it is parked in the sun.

Lastly, in case even after doing everything you can’t fix the problem, then it’s the right time to buy a new Bluetooth speaker for under 100 dollars.
