Oppo Enco W11 is a budget-friendly TWS that gives 5 hours of playback time. The music listening time is up to 20 hours with the charging case.
But, recently, I encountered a charging issue with my two years old Oppo Enco W11 right earbud.
Here I’ll share- what I did to fix that problem. If your Enco earbuds or case is not charging, follow the solutions I mentioned in this guide.
Why are my Oppo Enco W11 earbuds not charging?
The charging issue in wireless earbuds generally occurs because the metal contacts of earbuds do not connect with the metal pins of the charging case.
Wax stain build-up around the metal contacts also prevents the current flow, and as a result, one or both earbuds won’t charge.
In my case, the problem was wax stain build-up. I scratched the metal contacts with a toothpick and cleaned them with rubbing alcohol and a microfiber cloth.
After cleaning, the charging problem was resolved. You should also clean your Oppo Enco W11 earbuds with isopropyl alcohol and see if it starts charging or not.
In major cases, the charging problems resolve by cleaning the metal contacts. If it’s not resolved, try the other solutions mentioned below.

How To Fix Oppo Enco W11 Not Charging?
If one of your earbuds is not charging, it indicates the charging case functions perfectly. The problem is either with your earbuds, or the charging case has dust.
If both earbuds are not charging in the case, it means the problem is with the case, charging port, charging cable, or power adapter.
Here are easy troubleshooting methods-
1. Clean Your Charging Pins
There are two metal pins for each earbud. Over time, dust and moisture cover the charging pins. If you put your earbuds in the case, metal pins won’t connect.
The earbuds charges at 3 Volt, and only a thin dust layer can stop the current flow. As a result, neither of the earbuds won’t charge.
Clean your charging case with isopropyl alcohol and a toothbrush. Now, wipe out everything with a microfiber cloth.
Clean the metal contacts of your earbuds also. You can use a SIM ejector tool or toothpick to break wax stains and wipe them with isopropyl alcohol and microfiber.

3. Check Case Terminal Voltage
Oppo Enco W11 charging case has a 400 mAh rechargeable battery that charges your earbuds at 3 volts.
It will be a bit technical because you need a multimeter for this. Set the multimeter to 20V DC and check the voltage difference across both charging pins.
If the multimeter reading is close to 3 volts, means your case is functioning properly. If less, connect your case with a charger and check its reading.
If the voltage difference doesn’t increase, it indicates there are faults with your charging case, and you need to go for a replacement.
If the voltage reading increases, your case is charging, and you need to charge it for at least 2 hours.
