Xiaomi Mi Airdots wireless headphones (including the Basic, Pro, Pro 2 and SE models) have become some of the most popular gadgets due to the combination of price and quality. However, their compact design and minimalist case often pose the question: how do you know if the headphones are fully charged? Unlike wired counterparts, there is no usual connector with a burning indicator, only concise LEDs and sound signals.
In this article, we will discuss all the official and hidden ways of checking the charge - from decrypting the flashing of indicators to using the proprietary application Mi Home. You will learn how to distinguish the charge of the case from the charge of the headphones themselves, what the different colors of LEDs mean, and why sometimes headphones can show 100% charge, but discharge in 10 minutes. And also - typical user errors that reduce the battery life by 2 times.
1. Indicators on the case: decoding of colors and blinks
The main way to check the charge is by the LED on the front of the case, and its behavior depends on the headphone model and current status, and here's the full table of values for all Mi Airdots versions:
| Color of indicator | Blinking mode | Case value | Importance for headphones |
|---|---|---|---|
| White | It's burning all the time. | Case charge 80-100% | Headphones fully charged (in case) |
| Orange | It's burning all the time. | Case charge 30-79% | Headphones charge (in case) |
| Red. | It's burning all the time. | Case charge <30% (recharge required) | Headphones are discharged (charge required) |
| White/orange | Blink 1 time in 3 seconds | Case is on charge. | Headphones in the process of charging |
| Red. | Frequent blinking (2 times per second) | Charging error (check cable/connector) | Critical discharge of headphones (<5%) |
β οΈ Note: Mi Airdots Pro 2 and SE Case indicator can automatically turn off after 10 seconds after connecting to the charger. To check the current status, briefly press the button on the case - the indicator will light up for 3 seconds.
If the indicator does not burn at all, it can mean:
- π The case is completely discharged (it takes at least 5 minutes to charge the indicator to appear).
- π Core or connector malfunctioning USB-C/Micro-USB (Try another cable).
- π‘ Burned LED (earphones can be charged, but visually it is not displayed).
2.Audible cues: What voice cues mean
Mi Airdots (except Basic) are equipped with voice cues in Chinese or English, which are heard when you plug into a case and report the status of the charge.
- π "Battery Low (Low Charge) - Remains <20% energy.
- π "Battery very low (very low charge) <5%, earphones will soon be out.
- π "Power on" (enabled) + melody--headphone charge >50%.
- π "Power off (off) - charge <5% or headphones placed in a case.
- π "Connected β Headphones connected to the device (not connected to charge).
β οΈ Attention: Mi Airdots Basic models don't have audio cues - focus on the case indicator only. If you hear extraneous clicks or crackles when you connect to the case, this may indicate contact oxidation (needs to be cleaned with alcohol).
To check the charge of headphones without a case:
- Take the headphones out of the case - they will automatically turn on.
- Double tapping on the touch panel of any headphone will cause a voice message about the charge.
- If there is no sound, the headphones are discharged (<5%).
π‘
If voice prompts interfere, they can be disabled in the Mi Home app (section "Hearphone settings β Voice prompts").
3. Check the charge through the Mi Home app
The most accurate way is to use the official Mi Home app (available for Android and iOS), which shows the separate charge of the case and each headphone in percentage.
- Download Mi Home from Google Play or App Store.
- Sign in or sign in through your Xiaomi/Mi Account.
- Click Add Device (+) β Select Headphones β Mi True Wireless Earphones.
- Follow the instructions on the screen (earphones must be on and not connected to other devices).
After the connection, the control panel will open with information:
- π Left/right headphone charge (in %).
- π¦ Case charge (in %).
- π Working hours (residue in hours).
- π Volume level and active sound profile.
β οΈ Note: If the app displays a 100% charge but the headphones are quickly discharged, this is a sign of battery wear.Try resetting the headphone settings (press the button on the case for 15 seconds before flashing red and white).

4. How to distinguish the charge of the case from the charge of headphones
Many users confuse the charge of the case (which powers the headphones) and the charge of the headphones themselves.
- π Case Charge: Shows the indicator on the front panel of the case, determines how many times the case can fully charge the headphones (usually). 3β4 Charged from the socket / power bank via USB-C/Micro-USB.
- π§ Headphone charge: Shows the indicator inside the case (with the lid open). Determines battery life (4-5 hours for Basic, 6-7 for Pro 2). Charged from the case when placed inside.
π Lifehack: To check the charge of headphones without the application, follow the following steps:
- Open the case cover - the indicator inside will show the charge of the headphones.
- Close the lid and press the button on the case - the indicator will show the charge of the case.
If the indicator inside the case:
- π’ Burning green/white β headphones charged 60-100%.
- π‘ Burning orange - charge 30-59%.
- π΄ Burning red - charge <30%.
- π₯ Not burning β headphones are discharged or contacts are oxidized.
Why is the case charged and the headphones not?
Typical problems and their solutions
Even with proper charging, users are experiencing problems, and here are the most common ways to fix them:
| Problem. | Possible cause | Decision |
|---|---|---|
| Case indicator does not burn when charging | Faulty cable/power supply | Try another cable and socket. Use a 5V/1A power supply. |
| Headphones discharge in 1-2 hours | Battery wear or background processes | Reset the settings (press the case button for 15 seconds). Update the firmware through Mi Home. |
| The case is charged only in a certain position. | Poor contact in the USB-C connector | Clean the dust connector with a toothpick, check the cable for damage. |
| The indicator flashes red and white alternately | Firmware failure or connection conflict | Reset the headphones to factory settings (see instructions above). |
| Headphones don't charge in the case | Oxidation of contacts or imbalance of cells | Clean the contacts with alcohol. If it doesn't work, replace the battery. |
β οΈ Warning: If after resetting the headphones stopped connecting to the phone, remove them from the list of conjugated devices in the Bluetooth settings and reconnect (press the button on the case for 5 seconds before flashing white).
π§ Council for extending the life of the battery:
- π Donβt keep your headphones on charge for more than 24 hours β this reduces battery life.
- π‘οΈ Avoid charging at a temperature below +5Β°C or higher +35Β°C.
- π Once every 3 months, discharge the headphones to 0% and charge to 100% for controller calibration.
6. Alternative methods of charge checking
If standard methods donβt work, try these options:
- π± Through Bluetooth settings on your smartphone: Connect your headphones to your phone. Open your settings. β Bluetooth. Click on the headphone name (Mi Airdots...). Some smartphone models (e.g. Xiaomi, Samsung) will display the charge level.
Through third-party applications:
Apps like Battery Widget Reborn or AccuBattery can show the power of Bluetooth devices, which is less accurate than Mi Home, but it is an option if the proprietary software does not connect.
Through a USB tester:
If you have USB-Tester (e.g. Xiaomi) USB Tester, connect the case to it. Tester will show the charging current: if he <100 mA, contacts are contaminated or battery is worn out.
π‘ Lifehack for Mi Airdots Pro 2: These headphones support fast charging. If you plug the case into a Quick Charge 3.0 power source, the charge from 0% to 100% will take up. ~1 hour (instead of the standard 1.5-2 hours).
π‘
The most reliable way to check the charge is the Mi Home app, which shows the exact percentages for the case and each headphone separately, and also warns of a critical charge level.
7.How to extend the life of the battery: tips from Xiaomi engineers
The average battery life in Mi Airdots is 2-3 years (300-500 charge cycles).
- π Avoid full discharge: Optimal range 20-80%, full discharge to 0% and charge to 100% accelerate degradation.
- π‘οΈ Keep it in a cool place: At a temperature higher +30Β°The battery loses up to 20% of its capacity per year.
- β‘ Use the original cable: Cheap cables can deliver unstable voltage, which harms the charging controller.
- π Regularly update firmware: New versions optimize power consumption. Check for updates in Mi Home.
- π§Ή Clean contacts: Oxidation increases resistance, leading to overheating and rapid discharge.
β οΈ Warning: If the headphones heat up during charging (case temperature is higher) +40Β°C, turn them off the power immediately:
- Faulty battery (risk of swelling).
- Short circuit in the charging circuit.
- Use of an uncertified power supply unit.
