Tronsmart Earbuds Not Charging

Tronsmart earbuds are among the top choices in the market, offering a range of true wireless Bluetooth earbuds such as the Onyx Neo, Spunky Beat, and Onyx Ace models. They all excel in sound quality and performance.

However, issues arise when these earbuds stop charging. I encountered the same problem last week with my Tronsmart Onyx Apex earbuds.

Upon searching online for troubleshooting tips, I found no comprehensive guide. After reaching out to their support team, I managed to discover some simple fixes.

If you’re experiencing similar charging issues, follow this guide for easy solutions. I’ve compiled all the possible reasons and their respective fixes to help resolve your problem.

Why is Tronsmart Earbuds Not Charging?

There could be several reasons why your Tronsmart earbuds are not charging:

  • Dirty Charging Contacts
  • Faulty Charging Cable
  • Battery Issues
  • Charging Case Malfunction:
  • Software Glitch
  • Overheating
  • Moisture or Water Damage

These are some of the common reasons why your earbuds may not be charging.

Remember, it’s important to identify the reason behind your problem before attempting any fixes, as this can help you resolve the issue more quickly.

How to Fix Tronsmart Earbuds Not Charging?

Now that we’ve identified some of the common reasons, let’s move on to some easy fixes.

1. Clean the metal contacts:

Metal contacts, which are small, conductive metal points located on both the charging case and the earbuds, serve as points of electrical connection.

They facilitate the flow of electricity from the charging case to the earbuds for charging purposes.

However, over time, dust and debris can accumulate on these metal points. When the metal contacts become dirty, they may fail to establish proper contact with the corresponding contacts on the earbuds.

This impedes the flow of electricity required for charging. Therefore, regular cleaning of these metal contacts is essential to ensure efficient charging performance.

Here’s how to clean metal contacts: 

  • Power off both the earbuds and the case.
  • Remove the earbuds.
  • Wipe the metal contacts with a soft, dry cloth to remove dirt.
  • If needed, use a cotton swab dampened with isopropyl alcohol to clean stubborn stains.
  • Allow the contacts to air dry completely.
  • Reassemble the earbuds into the case.
  • Power on and test the earbuds to ensure proper functionality.

2. Faulty Charging Cable

Another major reason why your earbuds may not be charging could be a faulty charging cable.

A faulty charging cable could be physically damaged or have loose connections or compatibility issues. To resolve this problem, follow these steps:

  • Inspect the cable for visible damage like fraying, exposed wires, or bent connectors. If damaged, replace it.
  • Clean connectors to remove dirt or debris that may cause poor contact.
  • Test the cable with a different charger to determine if the issue is with the cable or charger.
  • Try the cable with another compatible device to see if it charges properly.
  • If none of the above steps fix the issue, replace the cable with a new one from a reputable manufacturer.

3. Ensure Proper Alignment of Earbuds: 

Improper alignment can also prevent the earbuds from charging effectively.

As discussed above, there are two metal contact points on both earbuds and charging case, which are the connection points for charging.

Ensure Proper Alignment of Earbuds

So when the earbuds are not properly aligned in the charging case, the metal contacts may not make full contact with each other, leading to an incomplete electrical circuit and preventing the flow of power needed for charging.

To fix this issue:

  • Check alignment: Ensure the earbuds are correctly placed in the charging case, aligning the metal charging contacts on the earbuds with those in the case.
  • Reposition: Adjust the earbuds within the charging case if they’re not aligned properly until you hear or feel a click, indicating they’re securely in place.
  • Remove obstructions: Check for and remove any debris blocking the alignment of the earbuds and the charging case.
  • Ensure snug fit: Make sure the earbuds sit securely in the charging case without wobbling. This ensures consistent alignment and reliable charging.

4. Reset the Earbuds:

If your earbuds are still not charging after attempting the fixes mentioned above, the next best and simplest solution is to perform a reset. 

Resetting Tronsmart earbuds can resolve charging issues by eliminating potential glitches or errors in the device’s system. 

This action essentially restores the earbuds to their default settings, which might fix any software-related issues that are stopping them from charging.

To reset Tronsmart earbuds, follow these steps:

  • Ensure that the earbuds are disconnected from any devices and turned off.
  • Place both earbuds into the charging case and close the lid.
  • Press and hold the button on the charging case for at least 10-15 seconds.
  • After holding the button for the specified time, release it.
  • Open the charging case lid and remove the earbuds.
  • Turn on the earbuds and try charging them again to see if the issue has been resolved.

5. Update Firmware:

Outdated firmware in Tronsmart earbuds can also cause charging issues due to various reasons.

One common issue is that the older firmware might not support efficient power management protocols, leading to inconsistencies in charging.

Additionally, outdated firmware might have bugs or glitches that interfere with the charging process.

To fix this issue, you can try the following steps:

  • Download Tronsmart App: If there’s a dedicated app for firmware updates, get it from the Google Play Store (for Android) or the Apple App Store (for iOS).
  • Pair Earbuds: Make sure your earbuds are connected to your device via Bluetooth.
  • Open Tronsmart App: Launch the Tronsmart app on your device.
  • Check for Updates: Look for the option to check for firmware updates within the app. It might be in the settings or a specific firmware update section.
  • Follow Instructions: If an update is available, follow the on-screen instructions to download and install the firmware update. Be patient as this process might take some time.
  • Complete Update: After the firmware update finishes, your earbuds may disconnect and reconnect automatically. Follow any additional instructions provided by the app to finalize the update.
  • Test Earbuds: Once the update is complete, test your earbuds to ensure they’re working properly. Check if any previous issues, like charging problems, have been resolved.

6. Fix Battery Issues:

Battery issues can indeed be a common culprit when Tronsmart earbuds fail to charge. Here are a few potential battery-related reasons and their corresponding fixes:

Battery Drain:

If the battery of your Tronsmart earbuds has completely drained, they may not charge immediately.

Allow them to sit in the charging case for at least 30 minutes to an hour to see if they start charging. If they still don’t charge, move on to the next steps.

Dirty Charging Contacts:

Dust, lint, or debris might accumulate on the charging contacts of both the earbuds and the charging case, preventing proper connection and charging.

Use a soft, dry brush or cloth to clean the charging contacts carefully. Be gentle to avoid damaging them.

Faulty Charging Case:

If the charging case itself is defective, it may not supply power to the earbuds effectively.

Try using a different charging cable and power source to rule out any issues with the power input.

If the problem persists, contact Tronsmart customer support for a possible replacement or repair.

Battery Degradation:

Over time, the battery capacity of the earbuds may degrade, leading to difficulty in holding a charge.

Unfortunately, there’s not much you can do to fix this issue apart from replacing the earbuds or their batteries if they’re replaceable.

7. Warranty Claim: 

If you’ve tried all the above-mentioned fixes and none have resolved the issue, the best course of action is to claim warranty support from Tronsmart.

Tronsmart offers an 18-month warranty period for their products. Simply email them at to contact their support team.

Provide your invoice along with a description of the issue you’re experiencing. With luck, you’ll be able to successfully claim warranty coverage.


I hope that by following these simple and effective fixes, you’ve managed to resolve the charging issue with your Tronsmart earbuds.

Follow each step carefully, and if you encounter any further issues, don’t hesitate to contact their support team for assistance.
