Reasons Your Jbl Speaker Keeps Turning Off

Battery Failure

JBL Bluetooth speakers have rechargeable batteries which must have adequate charge to operate optimally. JBL speakers use high-capacity Lithium-ion batteries. Although these batteries retain power for extended periods. They can only withstand 300 to 400 charge cycles before losing their ability to hold a charge.

Constant overcharging or exposure to extreme temperatures can significantly degrade the battery’s performance over time. Lithium-ion batteries have a short lifespan and might require replacements sooner. If the battery level is low, your speaker won’t stay on for long.

Auto-Off Feature

Most JBL speakers have an automatic turn-off feature that will shut down the speaker after a certain amount of inactivity. This is a feature that helps you save battery life for your music speaker. When you do not play music for a period of time, the speaker will automatically turn off. This may be uncomfortable for some people who don’t have their hands free to adjust music, for example making cakes or taking a bath.

Faulty Circuit Board

Its sturdy construction and ability to withstand water make the JBL Charge  4 a popular choice. However, if not handled with care, any product might develop flaws. Even if only a few droplets of water accidentally enter the machine, damage to the internal design may occur.

You should promptly take it to the company’s warranty or a reliable repair shop in such a circumstance. Use conventional ways like drying it in a drier or placing it in a jar of rice, but don’t leave it for too long. More severe issues with the gadget could be the result of this.

Outdated Firmware

JBL speaker uses firmware that needs to be updated occasionally. Since speakers are not as interactive of an electronic device as items such as phones and computers, not everyone realizes that they require updates to keep working properly. Using outdated firmware can cause issues with normal operations and possibly result in the speaker shutting down or turning off randomly.


One of the most common reasons why your JBL speaker is turning off is overheating. Using the speaker outdoors or in direct contact with the sun can cause the speaker to overheat. Many electronic devices can overheat quite easily and are designed to shut down when this happens to make sure nothing gets permanently damaged.

How To Fix a JBL Charge  4 Speaker That Keep Turning Off?

Update Firmware

If pressing the power button multiple times does the trick, it is most likely a firmware problem- Download the JBL app if you haven’t already downloaded it, connect to the internet, and then see if the “firmware update” bubble pops up. If it does, make sure to follow instructions and update it, and if it doesn’t, just ignore this.

Reset The Power

First, make sure your speaker is not connected to a power supply or charger. Next, hold down the power button for 30 seconds.

Due to a forced power cycle. A forced power cycle is when a device is turned off and then turned back on using the physical power button.

Replace The Battery

A faulty, old, or swollen battery will prevent the JBL Charge  4 from turning on or working properly. If you had your speaker for more than two (2) or three (3) years, there’s a high chance its battery has completed its charging cycles. The Lithium-ion polymer battery will also get damaged if you store the speaker improperly, expose it to high temperatures, or experience physical damage.

To fix this, you must replace the battery with a new one. Please pay attention to the replacement battery for the speaker, it must be genuine. Because if you use a battery that is not suitable for the device, the battery and device may not adapt and explode, causing danger to the user. Send the speaker to an authorized repair center (if you still have a warranty) or to a local electronic repair shop and they will replace it for you.

Button Combinations

#4. PlayPause + Vol.Up + Vol.Down -> hard reset (should simulate disconnecting the battery). This is often the best way to restore a bricked speaker, and will fix most issues, it has worked many times for me

#6. PlayPause + Vol.Up for 2 seconds -> factory settings (erases the history of paired devices).
