However, like any electronic device, users may occasionally encounter issues, one of which is the frustrating problem of the Oppo Enco W11 not charging. This issue can be a significant hindrance to enjoying your music or taking calls wirelessly, and understanding its potential causes and solutions is essential to keep these earbuds functioning at their best. In this article, we will delve into the common reasons behind this problem and provide practical troubleshooting steps to help you get your Oppo Enco W11 earbuds charging again.

The Oppo Enco W11 is known for its budget-friendly price tag and the ability to deliver up to 5 hours of playback time on a single charge. With the help of its charging case, users can extend their music-listening experience to a remarkable 20 hours. However, if you happen to own a two-year-old pair and are facing charging issues, you’re not alone. Recently, I encountered a problem with my right earbud, and I want to share the solutions I found to resolve it. In this guide, I’ll provide step-by-step instructions on how to fix charging problems with your Enco earbuds or charging case, ensuring you can continue enjoying your wireless audio experience.

Why are my Oppo Enco W11 earbuds not charging?

Charging problems in wireless earbuds are often attributed to a common issue – poor connectivity between the metal contacts of the earbuds and the metal pins in the charging case. Additionally, the accumulation of wax stains around these metal contacts can disrupt the flow of current, leading to a situation where one or both earbuds fail to charge.

In my particular case, I discovered that the root cause of the problem was indeed wax stain build-up. To resolve this issue, I carefully used a toothpick to gently scrape away the wax from the metal contacts. Following this, I cleaned the contacts thoroughly using rubbing alcohol and a microfiber cloth. This simple maintenance step proved effective in restoring the charging functionality of my earbuds.

Upon cleaning the earbuds, the charging issue I encountered was successfully resolved. I would recommend attempting the same solution by cleaning your Oppo Enco W11 earbuds with isopropyl alcohol to see if it restores their charging functionality.

In many instances, charging problems can indeed be resolved by addressing issues with the metal contacts. However, if this initial solution doesn’t work, don’t worry. There are additional troubleshooting steps and solutions mentioned below that you can try to rectify the problem.

How To Fix Oppo Enco W11 Not Charging?

When you encounter a situation where one of your earbuds isn’t charging, it’s a clear indication that the charging case is functioning correctly. In this scenario, the issue likely lies either with the earbud itself or with the presence of dust or debris in the charging case.

However, if you find that both earbuds are failing to charge within the case, it suggests that the problem could be attributed to issues with the case itself, the charging port, the charging cable, or the power adapter. Fortunately, there are straightforward troubleshooting methods available to help you pinpoint and address these problems.

1. Clean Your Charging Pins

Each earbud is equipped with two metal pins designed for charging. Over time, these pins can become obscured by the accumulation of dust and moisture. When you place your earbuds in the case, these metal pins may fail to make proper contact, leading to charging issues.

Given that the earbuds operate on a 3 Volt charging system, even a thin layer of dust can obstruct the flow of current, preventing both earbuds from charging effectively.

To address this issue, it’s advisable to clean your charging case meticulously using isopropyl alcohol and a toothbrush. This cleaning process should be thorough, ensuring that all residues are removed. Finish by wiping everything down with a microfiber cloth to maintain optimal charging performance.

Don’t forget to clean the metal contacts on your earbuds as well. You can employ a SIM ejector tool or a toothpick to gently remove any wax stains that may have accumulated. Follow this up by wiping the metal contacts with isopropyl alcohol and a microfiber cloth to ensure they are spotless and ready for efficient charging.

2. Reset Your Earbuds

Typically, charging problems with earbuds can be resolved by cleaning the metal contacts. However, it’s worth noting that occasionally, issues can also arise from software glitches.

To address pairing or charging problems with your Oppo Enco W11 earbuds, you can perform a reset. Follow these steps to reset your Enco earbuds:

  • Access your smartphone’s Bluetooth settings.
  • Unpair and remove the Oppo Earbuds from the list of connected devices.
  • Place both earbuds into the charging case while keeping the case lid open.
  • Next, press and hold the right earbud for approximately 13 seconds until the case’s LED indicator starts flashing red and green.
  • Close the lid of the case and then open it once more.

That’s all there is to it! Your Oppo Enco W11 earbuds have now been successfully reset and are ready to be paired with any smartphone.

3. Check Case Terminal Voltage

The charging case of the Oppo Enco W11 is equipped with a 400 mAh rechargeable battery designed to provide a 3-volt charge to your earbuds.

For those comfortable with technical troubleshooting, a multimeter can be a valuable tool in diagnosing potential issues. To begin, set your multimeter to the 20V DC setting and measure the voltage difference across both charging pins.

If the multimeter reading is in close proximity to 3 volts, this indicates that your case is functioning as intended. However, if the reading is lower, connect your case to a charger and monitor the voltage reading.

If the voltage difference fails to increase, it may signify underlying faults with your charging case, necessitating a replacement.

On the other hand, if the voltage reading does increase, it confirms that your case is indeed charging. In this case, allow it to charge for a minimum of 2 hours to ensure it reaches an optimal charge level.

4. Contact Customer Support

If you’ve exhausted all the aforementioned troubleshooting methods and your issues persist, it’s crucial to consider the possibility of a hardware fault. In such cases, it’s advisable to seek professional assistance.

You can initiate this process by reaching out to Oppo’s Customer Support. Be prepared to provide them with essential information, including the product’s serial number and the original warranty claim invoice. This will help expedite the diagnosis and resolution of any potential hardware issues with your Oppo Enco W11 earbuds or charging case.


The Oppo Enco W11 earbuds are equipped with 40 mAh batteries, and they typically require about 1.5 hours to charge when placed inside the case. To ensure a full charge, connect the charger and leave it plugged in until the case is fully charged. If the charging issue persists despite following these steps, consider resetting your Oppo Enco W11 by tapping and holding on the right earbud, as this can sometimes help resolve problems related to connectivity and charging.
