How to accurately check the charge of headphones Xiaomi Redmi: all ways

Xiaomi Redmi wireless headphones have become an integral part of everyday life: they accompany us on jogs, in transport and even during work calls. But suddenly a battery that runs out can ruin any moment. How to check the charge of headphones if the manufacturer does not always conveniently display this information? In this article, we will analyze all the current ways of 2026 – from standard to little-known life hacks that work even on older models.

The problem is that Redmi Buds, Redmi AirDots and other series often don't show the exact percentage of charge in the smartphone interface. Indicators on the case are limited to 1-4 LEDs, and in mobile OSes (especially on Android below version 12), data can be delayed or absent. But there are solutions! Next, you will find instructions for different scenarios, from quick check on the go to deep diagnosis through the engineering menu.

1. Standard method: Indicators on the case

The most obvious method is to look at the LEDs on the case of the charging case. Most Xiaomi Redmi models (e.g. Redmi Buds 4, Redmi AirDots 3 Pro) use the following logic:

• 🔴 1 flashing light, charge less than 25.
• 🟡 2-3 indicators: battery level from 25% to 75%, you can use another 1-2 days with moderate load.
• 🟢 4 lights -- 75 to 100 percent charge. Full power supply.
• 🔄 Blinking white/green – the headphones charge (if they are inside the case).

To activate the display, it is usually enough to open the case cover or press the button from the outside (if any). For example, in Redmi Buds 3 Lite, the button is located on the back panel - one short press will show the current level of charge.

⚠️ Attention: On the Redmi AirDots S (2020), the lights only burn when connected to charging. In offline mode, they are not active - this is not a breakage, but a feature of the firmware.

If the indicators do not respond at all, check:

• 🔌 Is the case connected to the food (maybe completely discharged).
• 🧹 Clean contacts on case and headphones – oxidation or dirt can block charge.
• 🔄 Try restarting your headphones (the method described in Section 5).

2. Checking through a smartphone (Android/iOS)

Modern smartphones Xiaomi, Redmi, POCO (based on MIUI 12+) automatically display the charge level of the connected headphones in the notification panel.

On Android:

1. Connect the headphones to the phone via Bluetooth.
2. Turn the notification bar (swipe down from the top edge of the screen).
3. Find the headphone icon – next to the percentage of charge (e.g. Redmi Buds 4: 87%).

On iPhone (iOS 14+):

1. Open Settings → Bluetooth.
2. Find your headphones in the list of devices.
3. Click on the i icon next to the name – the charge level of the case and each headphone will be displayed separately.

If the data does not appear:

• 📱 Update the firmware of the smartphone (in) MIUI 13+ Headphone support improved).
• 🔄 Reconnect the headphones: forget the device in Bluetooth settings and pair again.
• 🛠️ Install the Mi Earphones branded app (link in Section 3).

💡

On some models (such as the Redmi Buds 4 Pro), the charge level is displayed only when the sound is played actively.

3.Mi Earphones' branded app

The official Mi Earphones app (available for Android and iOS) provides advanced headphone information, including:

• 📊 The exact percentage of charge of each headphone and case.
• ⚙️ Equalizer and touch control settings.
• 🔋 History of battery discharge (useful for diagnosing "gluttony").
• 🎧 Microphone and speaker test.

How to use:

1. Download the app from Google Play or the App Store.
2. Put the headphones on the phone.
3. Open the application - the charge will be displayed on the main screen.

⚠️ Note: The app may not recognize clones or headphones with unofficial firmware. If after the connection there is an error "Device is not supported", check the originality of the device.

4. Voice Assistant (Alice, Google Assistant, Siri)

Few people know, but voice assistants can tell the level of charge on the headphones.

• 🤖 Google Assistant (Android).
• 🍎 Siri (iPhone).
• 🗣️ Alice (Yandex, for Android smartphones).

Instructions for Google Assistant:

1. Activate the assistant with your voice (OK, Google) or hold the Home button.
2. Say, “What’s my headphone charge?” or “Show me the battery level of the Redmi Buds.”
3. The assistant will voice the percentage of charge or show a card with data.

For Siri (iPhone):

1. Hold the side button (or say "Hi Siri").
2. Ask, “What is the charge of my Xiaomi headphones?”

Limitations:

• 📵 It only works if the headphones are connected to the phone at the moment.
• 🔕 On some models (for example, Redmi Buds 3 Youth) assistants see only the charge of the case, but not the headphones themselves.

Put your headphones on the phone.|Activate the voice assistant|Make sure the microphone is not covered.|Check your internet connection (for Alice)-->

5.Reset and reset headphones

If neither of these things worked, it's possible that the headphones are stuck and don't display the charge level correctly, and hard reset will help, and the instructions are universal for most Xiaomi Redmi models:

1. Put both headphones in the case and close the lid.
2. Press and hold the button on the case (usually 10-15 seconds) until the indicator flashes red and white.
3. Open the lid - the headphones will reboot and mate again.

After discharge:

• 🔄 Connect your headphones to your phone as a new device.
• 📱 Check the charge level through the notification panel or the Mi Earphones app.

⚠️ Attention: Reset removes all user settings (such as Xiaomi account binding or custom control gestures) and will have to be reset again.

6. Alternative methods (for advanced users)

If the standard methods do not work, you can try non-obvious solutions:

Method 1: Engineering menu (Android only)

Some Xiaomi Redmi models transmit charge data to the hidden menu of the smartphone.

1. Open the Phone app.
2. Enter the code: ##4636###.
3. Go to the section Information about the battery.
4. Find the charge level of the Bluetooth device.

Method 2: Third-party applications

If Mi Earphones doesn’t support your model, try:

• 📱 Battery Monitor for Bluetooth (Android) – shows the charge in real time.
• 🍎 Battery HD+ (iOS – supports some Xiaomi models.

Method 3: Connecting to a PC

USB-C-enabled headphones (such as Redmi Buds 4 Pro) can be connected to your computer via cable, and in the Device Manager (Windows) or System Information (macOS), they can be displayed as a "Battery Device" with a charge level.

💡

If neither method worked, the problem is likely to be with the hardware (charge controller or battery), in which case only repairing or replacing the headphones will help.
