How to find out the percentage of charging on Xiaomi wireless headphones: all ways

Xiaomi wireless headphones have long been a popular accessory for a combination of price, sound quality and functionality. But many users face one problem: how to accurately determine the battery level? Unlike smartphones, where the percentage is displayed on the screen, this information is often hidden in headphones, especially for models without a display — AirDots Pro 2, Redmi Buds 4 or Xiaomi Buds 3T.

In this article, we’ll look at all the ways you can check your charge, from standard smartphone notifications to hidden voice assistant functions, how different the indicators are on different models, why the data isn’t displayed sometimes, and what to do if your headphones are running too fast, and a compatibility table for popular Xiaomi devices.

1. Standard Notifications on Smartphone (Android/iOS)

The easiest way is to use pop-up notifications on your phone, and when you connect Xiaomi headphones to your smartphone, it automatically shows the charge level of both the headphones and the case.

On Android (especially on Xiaomi/Redmi/POCO devices), the notification appears in the Quick Settings Panel when you open the case or remove the headphones. On iPhone, the information is displayed in the battery widget (swipe down from the upper right corner).

• 📱 Android: Open the case next to your smartphone → A pop-up window with interest will appear.
• 🍎 iOS: Connect your headphones → Swipe down for the battery widget (if supported).
• ⚡ Restriction: On certain firmware (for example, MIUI 12.5 and below) notifications are unstable.

If notifications do not appear, check:

1. Update the headphone firmware through the Mi Home or Xiaomi Wear app.
2. Reconnect the headphones to the phone (forget the device in Bluetooth settings and connect again).
3. Check if notifications are enabled for the Mi Bluetooth app (on Xiaomi smartphones).

Instructions for verification:

1. Install the Mi Home app (for older models) or Xiaomi Wear (for newer ones).
2. Connect the headphones to the phone via Bluetooth.
3. Open the app → find headphones in the list of devices → tap on them.
4. The charge level will be displayed on the main screen.

⚠️ Note: In some regions (e.g. Europe), the Mi Home app may not show charge percentage due to firmware limitations.

3. Voice Assistant (Google/Alice/Siri)

Few people know, but voice assistants can tell the charge level of the headphones, which doesn't work on all models, but it's worth trying if other methods aren't available.

For Android (Google Assistant):

1. Activate the voice assistant (long-term pressing of the Home button or voice command "OK, Google").
2. Say, “What is the battery level of my headphones?” or “How much battery does AirDots have?”
3. If the headphones support this function, the assistant will voice a percentage.

For iPhone (Siri):

Siri rarely supports third-party headphones, but you can try:

Hey, Siri, what's my headphone charge?

🔹 Which models do they support? These are usually new Qualcomm chips. QCC3040 And above (e.g. Xiaomi Buds 3 Pro or Redmi Buds 4 Active). Older models like AirDots Basic are not compatible.

💡

If the voice assistant does not recognize the headphones, try reconnecting them to the phone and repeat the request.

4. LED-Indicators on the case: decoding signals

If you don't have a smartphone, the lights on the case can help you determine the level of charge. Xiaomi has a standard signal system, but it differs depending on the model.

⚠️ Note: On some models (e.g. Redmi Buds 4 Lite), the indicator is lit white – in this case, blinking means low charge, and constant light is full.

To check the case charge:

1. Connect the case to the charger.
2. Press the button on the case (if any) – the indicator will show the current level.

5. Alternative applications (for advanced users)

If standard methods don't work, you can use side utility tools. They're suitable for models that don't display charge in the Mi Home.

• 📊 Battery Monitor for Bluetooth: Shows the charge of headphones in real time (requires Android 8.0)+).
• 🔍 nRF Connect: Advanced Bluetooth analysis utility (suitable for AirDots on Nordic chip).
• 📱 AccuBattery: Tracks the battery discharge of headphones when in use (not for all models).

How to use nRF Connect:

1. Install the app from Google Play.
2. Connect the headphones via Bluetooth.
3. Select the device in the list → Open the Battery Level tab.
4. If the headphones support the function, you will see a percentage.

⚠️ Note: Some applications require root rights or special permissions, such as nRF Connect, which may not show data if the manufacturer has blocked access to battery information.

The side of the app often doesn't work well. Before using, check the reviews for your headphone model.
