How to determine that headphones Xiaomi AirDots fully charged: all ways

Xiaomi AirDots wireless headphones (including the Pro, Pro 2, 3, SE and others) have become some of the most popular gadgets due to the combination of price and quality. However, many users face the problem of how to accurately tell if the headphones and case are fully charged? Standard instructions often keep silent about the nuances, and the indication can be confusing - especially for beginners.

In this article, we will discuss all possible ways to check the charge – from color signals. LED-You'll learn how long AirDots are charging across generations, how to tell the difference between headphones and case charges, and why the indicator sometimes lies. 30-40%.

If your headphones are discharged too quickly or the case does not hold the charge, at the end of the article there is a checklist for diagnosis and tips for restoring battery capacity.

1. Charge indicators on the case: decoding of colors and blinks

The main way to determine the status of charge is by the LED on the front of the case, but its behavior differs depending on the model and condition of the device. Here is the full decoding table for all versions of Xiaomi AirDots:

Important: AirDots 3 Pro and AirDots 4 models may have different lights, such as white only when the case is 100% charged, and orange only burns up to 99%. If your case flashes orange for longer than 1.5 hours, it is a sign of a battery or power supply malfunction.

To test the specific charge of the headphones, put them in the case and open the lid. The indicator will show the status of the headphones, not the case. If white is on, they are charged, if red, you need to recharge.

⚠️ Warning: If the indicator doesn’t burn at all, even when connected to charging, check the cable and port USB-C. In 60% of cases, the problem is in oxidized contacts or unoriginal cable with insufficient current strength.

2. Sound signals: what do squeaks mean when charging

In addition to light indications, Xiaomi AirDots emits audible signals that many users ignore, which duplicate information about the status of charge:

• 🔊 One short squeak when placing headphones in the case - the charging process has begun (the level of charge of the headphones) <80%).
• 🔊 Two short squeaks – headphones fully charged (100%).
• 🔊 Long squeak (1.5 sec) when connecting the case to charging - the case charging began (level <50%).
• 🔊 3 Note Melody – The Case is Fully Charged.

If there are no sounds at all, check:

1. Loudness on headphones (it may be set to a minimum).
2. The purity of contacts in the case – oxidation or dirt can block the connection.
3. Firmware version: In older versions, the sounds were turned off automatically after 5 charging cycles.

On the AirDots 3 Pro, you can turn off sounds in the Mi Home app settings (Notifications → Charging Signals). If you didn't do that and there are no sounds, that's a diagnostic reason.

3. Charging time: how much to wait to 100%

The charging speed depends on the model, the type of charger and the battery status. Here are the current data for popular versions:

Critical nuances:

• ⚡ Use of current charging <1A increases the charging time by 30-50%. Optimally — 5V/2A.
• 🔋 If the case is charged for longer than 3 hours, the battery has degraded (replacement is required).
• 🌡️ Charging at lower temperature +10°C or higher +35°C damages the battery.

💡

To speed up charging the AirDots 3 Pro case, use a Quick Charge 3.0+ charger (like the original from Xiaomi on 18W) that will reduce the time to 100% by 25-30%.

If the headphones are charged longer than the specified time, check:

1. The state of contacts in the case (clean with alcohol).
2. Cable used – non-original cables often do not provide the right current.
3. Firmware version: AirDots Pro 2 had a bug that slowed charging after 80 percent. Update the software via Mi Home.

4.Charge check through the Mi Home app

The official Mi Home app (available for Android and iOS) allows you to accurately track the charge levels of your headphones and case.

1. Connect the headphones to the phone via Bluetooth.
2. Open Mi Home and select Mi True Wireless Earphones (the name may vary depending on the model).
3. In the main menu of the device will appear charge indicator with a percentage ratio for the left earphone, right earphone and case.

Display example:

Left earphone: 100%




Right earphone: 95%




Case: 78%

If the application does not show charge:

• 📱 Update Mi Home to the latest version (older versions have limited support for AirDots).
• 🔄 Reconnect the headphones to the phone (forget the device) → re-synchronization).
• 🛠️ Reset the headphone settings (press the button on the case for 15 seconds before flashing red and white).

The AirDots 3 Pro and the newer Mi Home have detailed usage statistics, including the number of charging cycles and approximate battery life.

5.Typical errors: why headphones don't charge

If the indicators behave outside the box or charging does not go, the reasons may be as follows:

Check the cable and power supply (use original accessories)

Clean contacts in the case and on headphones with an alcohol napkin

Try another one. USB-port

Update the headphone firmware through Mi Home

Reset the headphone settings (press the button on the case for 15 seconds)

-->

Common symptoms and solutions:

⚠️ Warning: If after cleaning contacts and resetting the headphones still do not charge, do not try to disassemble the case yourself - in 90% of cases this leads to damage to the board.

In AirDots 3 Pro and later, there is an automatic power outage feature when overheating, so if the case heats up above 40°C, the charging stops before cooling down, which is normal behavior, not breakdown.

6 How to extend the life of the battery: 5 rules

The average battery life in Xiaomi AirDots is 300-500 charge cycles (about 2-3 years when used actively).

• 🔋 Don't keep your headphones on charge for more than 2 hours after reaching 100%. overcharging reduces battery life.
• 🌡️ Avoid charging at extreme temperatures (below 0)°C or higher than 35°C).
• 🔄 Once a month, conduct a full cycle of discharge-charging (discharge the headphones to 0%, then charge to 100%).
• 📵 Do not store headphones in a case with a charge level of 0% for longer than 2 weeks - this can lead to a deep discharge.
• ⚡ Use only original cables and power supplies with support for the right current.

In AirDots 3 Pro and later, there is an optimized charging function that automatically limits current after 80% to save the battery.

1. Open Mi Home.
2. Pick your headphones.
3. Go to Battery Settings → Optimized Charging.

💡

Storing headphones with a charge level of 40-60% in a cool place (15-25 ° C) slows down the degradation of the battery with prolonged downtime (for example, if you do not use them for several months).

If the battery capacity has dropped to 60-70% of the original (earphones keep a charge of less than 2 hours), consider replacing. In Xiaomi service centers, this service costs from 1,500 to 2,500 rubles depending on the model.
