Why Xiaomi wireless headphones don’t charge in the case and how to fix it

You put Xiaomi AirDots, Redmi Buds or Xiaomi FlipBuds in your charging case, but the indicator doesn't burn and the battery level doesn't change? Case charging is one of the most common wireless headphone malfunctions, most often caused by contaminated contacts, unbalanced batteries or software failures. 80% of the time, you can fix the situation yourself without going to the service center.

In this article, we will look at all the possible reasons why Xiaomi headphones stopped charging in the case, from a banal lack of power to hardware breakdowns. You will get step-by-step instructions with photos, a table of case and headphone compatibility, and tips for prevention. If after checking it turns out that the problem is in the battery or controller, we will tell you how to minimize the cost of repairs.

1. Check the obvious: power and connection

Before you disassemble the case or reset the settings, make sure that the problem is not the basics.

• 🔋 Case Charge: Connect the case to the charger for 10-15 minutes. If the indicator does not light up, try another cable or power supply (preferably original from Xiaomi with Quick Charge support).
• 🔌 Quality of contact: Check if the headphones are sitting tightly in the nests of the case, sometimes they are displaced due to impacts or deformation of the body.
• 📱 Battery status: Open the Mi Home or Xiaomi Wear app and check the case's charge level.If it's below 5%, the headphones may not charge.

Pay special attention to the cable and the adapter. Cheap, unoriginal charges often don't provide enough current, and the case thinks it's not connected to the network. Try charging the case from the computer through the computer. USB-port – if the indicator lights up, the problem is in the power supply.

Contact cleanup: the main culprit of the problems

In 60 percent of cases, the headphones don't charge because of oxidized or contaminated contacts, and dust, sweat, cosmetics, and even ordinary moisture eventually form a plaque that prevents current transmission, and you need to clean carefully so that you don't damage the gilded coating.

You'll need:

• 🧴 Cotton swabs (preferably with a sharp end).
• 💧 Alcohol (isopropyl 90%+ ordinary medical).
• 🧲 Soft brush (for example, to draw or clean the keyboard).
• 🔍 Lupa (optional, for accurate cleaning).

Step-by-step:

1. Remove the headphones from the case and turn them off (press the button for 5-10 seconds, if any).
2. Wet the cotton swab in alcohol and gently wipe the contacts on the headphones (usually 3-4 gold dots).
3. Do the same with the contacts in the case - they are located in the recesses where the headphones lie.
4. Allow all the details to dry for 10-15 minutes (alcohol evaporates quickly, but it is better not to rush).
5. Blow the nests of the case with compressed air (you can use a canister to clean the equipment or just blow heavily).

Never use abrasive materials (sandpaper, needles, knives) to clean, which remove the protective coating of contacts, speeding up corrosion. If the plaque is not removed with alcohol, try a special contact fluid (such as Contact Cleaner).

3. Resetting headphones and case settings

If the cleanup didn't help, the problem could be a software glitch: Xiaomi's wireless headphones have a built-in controller that sometimes "hangs" by blocking charging, in which cases a full factory reset helps.

How to drop headphones:

1. Put both headphones in the case and close the lid.
2. Press and hold the button on the case (usually located on the side or bottom) for 15-20 seconds until the indicator flashes red and white.
3. Open the case cover - the headphones should automatically turn off and reset all settings.

How to drop the case:

• Connect the case to the charger.
• Press the reset button (if any) for 10 seconds. In some models (for example, Xiaomi AirDots Pro 2), you need to press the button 5 times in a row.
• After the case is discharged, it can discharge — that's normal. Let it charge for 1-2 hours.

After resetting, the headphones and the case will go back to factory settings, and you'll have to reconnect them to your phone via Bluetooth, but charging should be restored.

💡

If the headphones do not connect to the phone after reset, remove them from the list of conjugated devices in the Bluetooth settings and search again.

4. Checking the compatibility of headphones and case

Sometimes, users find that the headphones of one Xiaomi model do not charge in a case from another – even if they are externally identical, this is due to differences in charging protocols and the location of contacts.

The table below shows the compatibility of popular models:

If you're using a case from another model, try to return the original one, and also check if the headphone locks in the nests have deformed, because sometimes they break, and the headphones don't fully sit down.

5. Diagnostics of battery and charging controller

If none of the previous methods worked, the problem may lie in the hardware:

• 🔋 Battery wear (especially relevant for headphones older than 2 years).
• 🔌 Breakdown of the charging controller in the case or headphones.
• ⚡ Chain break due to falls or mechanical damage.

How to check the battery:

1. Put the headphones in the case and connect it to the charger.
2. If the case indicator is on, but the headphones do not charge - the problem is in their batteries.
3. If the indicator does not burn at all, the case (controller or its battery) is defective.

For accurate diagnosis, you can use a multimeter:

1. Put the multimeter in voltage measurement mode (DC 20V).
2. Connect the probes to the charging contacts in the case (plus and minus).
3. The voltage should be in the range of 4.8-5.2V. If it is below 4.5V or is absent, the case is faulty.

⚠️ Attention! If you don't have experience with multimeters, don't disassemble the case yourself - the risk of short circuit or damage to the board is very high.

Cost of repair:

• 🔧 Replacement of the battery in headphones: 800-1500 ₽ (model-wise).
• 🔧 Repair of the case controller: 1200–2000 ₽.
• 🔧 Full replacement of case board: 2500-3500 ₽ (Sometimes it’s cheaper to buy a new one).

6. Alternative charging methods (if the case breaks)

If the case is permanently out of order and the headphones are still working, you can try to charge them with workarounds, which is a temporary solution, but it will help to extend the life of the device until you buy a new case.

Ways:

• 🔌 Direct charging through tweezers: Carefully plug in the plus and minus from the power source (5V) You can only use it if you're confident in your actions.
• 🔋 Wireless charging (for supported models): Some Xiaomi cases (such as AirDots Pro 2) support Qi charging. Try putting the case on a wireless station.
• 🔄 Charging from another case: If you have a case from another model with the right contacts, you can temporarily use it (see compatibility table above).

For models with a Type-C connector (such as the Xiaomi FlipBuds Pro), you can try connecting the headphones directly to charging through an adapter, but this requires soldering or a special adapter.

💡

If the case is completely dead and the headphones are still working, the most reliable option is to buy the original case on AliExpress or in the official Xiaomi store. ₽, cheaper.

7. Prevention: how to prolong the life of headphones and case

To avoid future charging problems, follow simple rules:

• 🧼 Clean the contacts of headphones and case with alcohol once every 1-2 months.
• 🔋 Proper charging: Do not leave your headphones in a case on charging for more than 24 hours. Use the original cable and adapter. Avoid overheating (do not charge in direct sunlight).
• 🌡️ Storage conditions: Keep the case in a dry place (humidity) <60%). Avoid sudden temperature changes.
• 📱 Firmware Update: Check for updates in the Mi Home app – they often fix charging bugs.

If you use headphones every day, the battery will wear out in 1.5 to 2 years, and after that time, charging can become unstable, which is a normal process of degradation of lithium polymer batteries.

⚠️ Attention! Never disassemble a case or headphones yourself if they are warranty. Xiaomi will cancel the warranty if there are traces of an autopsy. If the device is warranty, contact the service center immediately.
