Are you encountering the frustrating issue of rapid battery drain with your JBL Tune 120TWS wireless earbuds? Rest assured, you’re not alone. While these earbuds are renowned for their excellent audio experience, some users have experienced battery drain problems.

In this article, we will explore the common causes of jbl tune 120tws battery draining fast issue and provide you with twelve effective solutions to optimize the battery performance of your JBL Tune 120TWS earbuds.

Causes and Fixes for JBL 120TWS Battery Draining Fast:

Excessive Bluetooth Connectivity:

Continuous Bluetooth connection between your earbuds and device can drain the battery, even when not actively playing audio.


To minimize unnecessary battery drain, disconnect or disable the Bluetooth connection when the earbuds are not in use. Disable the automatic connection feature in both your device and earbuds' settings, and manually reconnect them when needed.

Intensive EQ Settings:

Using intensive equalizer (EQ) settings on your device or earbuds can contribute to faster battery drain. These settings modify the audio output, requiring more power from the earbuds.


Consider adjusting the EQ settings to a more moderate level or using preset EQ profiles that are optimized for a balanced audio experience. By reducing the intensity of EQ settings, you can help conserve battery power.

Background Voice Assistant Activation:

Having voice assistants, such as Siri or Google Assistant, constantly listening for voice commands in the background can lead to increased battery drain. These assistants remain active and consume power even when not in use.


Disable or limit the background activation of voice assistants on your device. Configure the settings to require manual activation or adjust the sensitivity to reduce unnecessary power consumption. This helps optimize the battery life of your JBL Tune 120TWS earbuds.

Prolonged Listening Sessions:

Extended usage of the JBL Tune 120TWS leads to faster battery depletion, as the earbuds are designed for a specific playtime duration.


Improve battery life by taking regular breaks between listening sessions. Allow the earbuds to rest and recharge. Additionally, consider lowering the volume level or using the mono mode (using a single earbud) to conserve battery power.

High Volume Levels:

Listening to audio at high volume requires more power, resulting in faster battery drain.


Optimize battery usage by reducing the volume to a comfortable level that still allows you to enjoy your audio content.

This conserves battery life and safeguards your hearing. Experiment with different volume levels to find a balance between audio quality and battery conservation.

Inadequate Charging Practices:

Inconsistent or improper charging practices negatively affect the battery life and performance of the JBL Tune 120TWS.


Use the provided charging cable and ensure a secure connection between the earbuds and a reliable power source.

Avoid excessively long charging periods or leaving them plugged in overnight. Disconnect the charging cable promptly once the earbuds are fully charged to prevent overcharging.

Background Apps and Notifications:

Background apps, notifications, or excessive app usage on your connected device drain the battery life of the JBL Tune 120TWS through the Bluetooth connection.


Optimize battery performance by closing unnecessary apps, disabling or reducing notifications on your device, and minimizing background processes.

These steps conserve power and improve overall battery life, indirectly enhancing the battery performance of the JBL Tune 120TWS.

Firmware Issues:

Outdated or faulty firmware contributes to battery drain issues in the JBL Tune 120TWS.


Regularly check for firmware updates specifically for your JBL Tune 120TWS earbuds. Visit the official JBL website or use the manufacturer’s companion app, if available, to download and install the latest firmware version.

Keeping the firmware up to date resolves potential battery-related bugs and improves overall performance.

Environmental Factors:

Extreme temperatures, whether hot or cold, affect battery performance and lead to faster drain rates.


Adhere to the recommended temperature range provided in the user manual when storing and using the earbuds. Avoid exposing them to direct sunlight, extreme heat, or freezing conditions. Maintaining an optimal environment preserves their battery life.

Faulty Charging Case:

A defective charging case significantly impacts the battery life of the JBL Tune 120TWS, resulting in faster battery drain.


Report the issue with the charging case to JBL customer support or the retailer from whom you purchased the earbuds. Request a replacement and ensure you use the original charging case provided with the JBL Tune 120TWS for optimal performance.

Background Noise Reduction Feature:

The active background noise reduction feature consumes additional power and leads to faster battery drain when unnecessarily enabled.


Disable the background noise reduction feature when not in a noisy environment. Access the settings or companion app of the earbuds, if available, to turn off this feature. Disabling it when not needed conserves battery power.

Battery Degradation over Time:

Rechargeable batteries, including those in the JBL Tune 120TWS, experience degradation over time due to repeated charging cycles.


If you have been using the JBL Tune 120TWS for an extended period, consider replacing the earbuds' battery. Contact JBL customer support or consult a professional repair service to inquire about battery replacement options.


In addition to the previously mentioned causes and solutions, it’s important to be mindful of intensive EQ settings and background voice assistant activation as they can contribute to fast battery drain.

By adjusting EQ settings and limiting background voice assistant activation, you can further optimize the battery performance of your JBL Tune 120TWS earbuds.

Remember, implementing these solutions collectively will help ensure longer-lasting battery life, allowing you to enjoy uninterrupted audio experiences.
