JBL, a big-name brand in the industry, is known for its quality audio systems and reliability. Yet, no company, not even one with seven decades of manufacturing top-quality speakers and sound systems, is exempt from malfunctions.

You’re in the right place. I sought to find out the several reasons behind these malfunctions and how to solve this problem.



Turning off doesn’t have to be the end of your JBL speaker’s story. This guide explores various troubleshooting methods. From power issues to software glitches.

Reasons-Why JBL Speaker Keeps Turning Off?

With different speakers, particularly JBL models in home studios and home theaters,

I’ve encountered the problem of the JBL speaker turning off unexpectedly.

Through troubleshooting, I’ve identified a few reasons: outdated firmware, overheating, an overly sensitive auto-off function, or a broken charger port or outdated firmware .

Each of these issues has its own easy fix.

How To Fix-JBL Speaker Keeps Turning Off

This post aims to highlight these common issues and offer practical advice to keep your JBL speaker functioning smoothly.

Auto-Off Feature

A common reason for a JBL speaker turning off could be its automatic turn-off feature. This feature is designed to shut down the speaker during periods of inactivity.

If no music or audio is being played, this is a likely cause of your frustrating issue.

Although this is a battery-saving feature allowing for longer use, it can be a nuisance if you forget it’s there and the speaker automatically turns off.

To fix this issue and prevent your speaker from turning off while audio is playing, you need to interact with it more frequently.

This can be as simple as pressing play periodically to ensure it stays on and doesn’t activate the auto-off feature when it’s actually in use.


Overheating is a common reason why a JBL speaker might turn off.

Like most electronic devices, speakers can overheat and shut down to avoid being permanently damaged.

This is especially likely if the speaker is used outdoors in the sun, or indoors in a hot room, or if it’s covered by items like clothes or a blanket, impeding cooling down.

These issues can cause your speaker to stop working and suddenly shut off.

To fix this, let your speaker cool down to make it work again. If it’s really hot, move it from outdoors or away from a fan.

Turn on the speaker, and ensure to remove any items on top or around it to help it stay cool, letting it overheat less during normal use.

Placing it in the shade and away from direct sunlight for about 30 minutes or less can also help.

Outdated Firmware

Another issue is Outdated Firmware. Electronics, including the JBL speaker, rely on firmware being updated regularly.

Outdated firmware can cause issues in normal operations, like shutting down or turning off randomly.

This is similar to other interactive electronic devices like phones or computers which require regular updates to keep working properly.

This is true even for wireless speakers, as opposed to older, bookshelf-style speakers that connect with standard speaker wires.

How to Fix It:

The fix for this is simple: updating the firmware.

This quick fix involves connecting your JBL speaker to a computer using a USB cable, visiting the JBL website, and downloading the update.

You might also update wirelessly via your phone, using the JBL app. Just search for your speaker model and look for a firmware update in the owner’s manual or app.

Dirty or Damaged Charging Port

A Dirty or Damaged Charging Port can cause problems with your JBL speaker.

When trying to diagnose, it’s easy to see how an unnoticed dirty charging port can prevent your charging cable from working properly.

The direct contact between the charging points and the cable can be hindered by everyday use, leading to a build up of gunk.

Similarly, a damaged port, filled with dust and debris or with pins that are bent and don’t fit or look normal, could be broken.

Fixing a Dirty or Damaged Charging Port can be easy.

For a dirty port, using a toothpick or a cotton swab to loosen any gunk and grime, then scraping it out in a gentle sliding motion and blowing away the dirt and debris with compressed air or your own breath can work wonders.

However, if the charging port is severely damaged, it might be beyond an easy fix.

In such cases, considering a new speaker or checking if your warranty covers a replacement option can be the best course of action.

Random Glitch

A Random Glitch between your speaker and phone can lead to problems without any exact explanation.

Such glitches are a part of dealing with electronic devices and can randomly cause your speaker to turn off.

Fixing this involves Resetting your JBL speaker and phone. This can often iron out any glitches or problems.

To reset the speaker, press the Play and Volume Up buttons simultaneously for a few seconds until the speaker powers down and then turn on again. This should get it working properly.

The same resetting process applies to your phone – simply turning off and then back on.

Low or No Charge

The most obvious yet often overlooked issue is Low or No Charge. It’s one of those simple things that can cause a lot of frustration.

Your JBL speaker may have a low charge or no charge at all, leading it to turn off.

Sometimes, a battery warning with a beep or a voice notification indicates that the battery is running low.

But if it’s not plugged in, it will shut down and won’t turn on or work for more than a few seconds or minutes.


The fix for this simple problem is a simple fix.

Just Plug your speaker in to charge. This will resolve any issues if the battery is dead.

Make sure it’s properly plugged in and give it some time to operate as usual.

Battery Failure

Battery failure in JBL speakers is a common issue.

These devices use high-capacity Lithium-ion batteries designed to retain power for extended periods.

However, they have a relatively short lifespan, typically lasting 300 to 500 charge cycles. Over time, they start losing the ability to hold a charge.

Damaged Circuit Board

A damaged circuit board could be the reason your JBL speaker abruptly turns off.

The board’s inability to effectively manage current flow disrupts the functionality, leading to unexpected shutdowns.

Addressing this issue is complex and typically beyond a typical user’s technical skills.

Therefore, seeking assistance from a qualified electrician or consulting JBL for an authorized service center is advisable.

If the circuit board is irreparably damaged, the only remaining option might be to replace the entire JBL speaker.



Outdated Firmware

To maintain peak performance, JBL speakers need frequent updates.

These updates are essential for rectifying glitches and enhancing your speaker’s functionalities.

When the firmware becomes outdated, it can lead to your JBL speaker shutting down unpredictably.

Ensuring your speaker is up-to-date with the latest software is key to optimizing its usage.

Follow these steps for updates:

  1. Install the JBL Portable app on your smartphone (available for Android/iOS).
  2. Connect your speaker to your device using Bluetooth.
  3. Launch the JBL Portable app.
  4. Navigate to the Settings.
  5. Look for any available software updates.
  6. If updates are available, select them to start the installation process.
  7. After updating, restart your speaker to see if the issue is resolved.
