How to know exactly that headphones Xiaomi charged up to 100%: all the ways

Xiaomi wireless headphones are some of the most popular gadgets, thanks to a combination of price, sound quality and battery life. But even experienced users sometimes face the problem of how to tell if a device is fully charged? Because it depends not only on the duration of listening to music, but also on the health of the battery. In this article, we will examine all possible ways to check the charge, from standard indicators to hidden functions in the mobile application.

The thing about Xiaomi headphones (be it Redmi AirDots>, Mi True Wireless Earbuds or Xiaomi Buds) is that they don't always clearly signal the end of charging. For example, some models just turn off the indicator, while others change color from red to white. If you plug your headphones into a case and forget about them for an hour or two, how do you know that the process is complete? Next, step-by-step instructions for each model, including the rare cases where charging is "hangling" by 99%.

1. Standard charging indicators on the headphone case

Most Xiaomi models are equipped with LED indicators that show the charging status, but their behavior differs depending on the series.

• 🔴 Red – Charging in the process (battery level below 80%).
• 🟡 Orange/Yellow – charge from 80% before 99% (It is used in Redmi AirDots models. 2/3).
• ⚪ White is full charge (100%) and on some headphones, the indicator goes off completely.
• 🔄 Flashing red – charging error (for example, poor contact or faulty cable).

Important: on headphones Xiaomi Buds 4 Pro and Xiaomi FlipBuds Pro, the indicator on the case may behave differently. For example, when connected to the power source, it flashes white 3 times, and after full charging it burns constantly. Always check the instructions for your model, as even within the same line there can be differences.

💡

If the light doesn't burn at all, try clearing the contacts on the headphones and in the case with a cotton swab dipped in alcohol, often the problem lies in the oxidation of metal plates.

2. Sound signals and voice alerts

Many users are unaware that Xiaomi headphones can sound when they reach 100% charge, depending on the firmware and model:

• 🎵 Short melodic sound – standard full charge alert (e.g. Redmi AirDots S).
• 🗣️ Voice assistant – models with support for Xiao AI (For example, Mi True Wireless Earbuds Basic 2 can say “charging is complete” (in Chinese or English).
• 🔕 No sound – budget models (e.g. Redmi Buds 3 Lite) may not have sound alerts.

To hear the signal, the headphones must be removed from the case at the time of completion of charging. If they are in a closed case, the sound will be muffled, and some users confuse the signal of full charge with the notification of low battery charge (usually it is intermittent squeak).

3. Checking the charge through the mobile application

The most reliable way is to use the official Mi Home or Xiaomi Wear app (depending on the model), which not only shows the current charge level, but also allows you to set up alerts.

1. Connect the headphones to the smartphone via Bluetooth.
2. Open the Mi Home app (or Xiaomi Wear for new models).
3. Find your headphones in the list of devices (usually under Smart Devices or Audio).
4. On the main screen of the device will display the percentage of charge of the case and each headphone separately.

In some firmware, the app shows the charging schedule and the time to full charge. For example, Xiaomi Buds 3T Pro has a Smart Charging feature that automatically turns off power when it reaches 100% so as not to overheat the battery. If the application displays Charging is complete, but the indicator on the case is still burning, this is normal.

4. Charging time: when to wait 100%

If you don't have an indicator or an app on hand, you can use standard charging times, depending on the model and the type of charger.

Note that if you use wireless charging (Qi-enabled models), the time can increase by 30-50%, and the quality of the cable and power supply also affects speed. For example, if you charge the Xiaomi Buds 4 Pro from a laptop (USB 2.0), it will take up to 3 hours to fully charge, instead of the declared 1 hour.

💡

If the headphones charge for more than 4 hours, it's a sign of a battery or charger malfunction. Try another cable and power supply.

5. Frequent Errors: Why Headphones Don't Charge to 100%

Sometimes users experience a charge that freezes by 99% or 80%, and here are the main reasons and ways to eliminate them:

• 🔌 Bad contact: Clean the metal contacts on the headphones and in the case of dust and oxidation. + isopropyl.
• 🔋 Worn-out battery – if the headphones are over 2 years old, the battery could degrade. Check the actual capacity through the AccuBattery app (for Android).
• 📱 Incompatible power supply - some models (e.g. Redmi AirDots) 3) require blockage 5V/1A. Powerful chargers (9V/2A) may cause error.
• 🤖 Firmware failure – reset the headphones to factory settings (press the button on the case for 10-15 seconds before the indicator blinks).

Critical information: If the Xiaomi Buds 3/3T Pro headphones don’t charge above 80% even after reset, this may indicate activation of the overcharging protection, in which case only a replacement of the battery in the service center will help.
