How to find out the charge of wireless headphones Xiaomi: 7 proven ways

Xiaomi wireless headphones have long become the standard for millions of users - from the budget Redmi Buds 3 Lite to the premium Xiaomi FlipBuds Pro. But even with the most advanced models, the same problem arises: how to quickly check the charge level of headphones and case without connecting them to a smartphone? This is especially important on the road when you need to urgently assess whether there is enough charge for a long flight or training.

In this article, we'll look at all the different ways you can test your charge, from the standard (via smartphone notifications) to the little-known (hidden voice commands and engineering menus), and also why it sometimes doesn't work properly and how to fix it, and if your headphones don't show percentage of charge, you'll find a solution here.

1. Standard method: notification on a smartphone

The most obvious method is to look at the charge level in the notification that appears when you connect your headphones to your phone.Works on all Xiaomi/Redmi models with a Bluetooth 5.0 chip and higher.

How to do this:

• 📱 Open the notification curtain on your smartphone (swipe down from the top edge of the screen).
• 🔗 Connect your headphones to your phone (if they are not already connected).
• 🔋 Find a notification with your model name (e.g., "Redmi Buds 4 Active Connected"(). The device name will display the percentage of charge of each earbud and case (if it supports this feature).

⚠️ Note: On Android below version 8.0, the notification may not show percentages - only the battery icon without numbers.

2. via Mi Fit/Xiaomi Wear app

The official Mi Fit (older models) and Xiaomi Wear (newer ones) apps not only track activity, but also provide detailed information about the charge of the headphones, which is especially useful if the notifications on the phone are not working.

Instructions for Xiaomi Wear:

1. 📲 Install the app from Google Play or App Store.
2. 🔗 Connect your headphones to your phone via Bluetooth.
3. 🔍 Open Xiaomi Wear, find the Device tab → Choose your headphones.
4. 🔋 The main screen will display the charge of the left and right headphone, as well as the case (if supported).

For Mi Fit, the algorithm is similar, but the interface may be different.

• 🔄 Reboot Bluetooth on your phone (Settings) → Bluetooth → switch off).
• 📦 Remove the headphones from the list of associated devices and connect again.
• 🔄 Update the firmware of the headphones (instructions in the section "Update firmware").

3. Voice assistant (for models with AI support)

Some Xiaomi models (like the FlipBuds Pro or AirDots 3 Pro) support voice commands to check the charge.This is convenient when the phone is not available (for example, while jogging).

How to activate:

1. 🎧 Put on your headphones and make sure they are connected to your phone.
2. 🗣️ Tell the command, “Hey Mi, what is the charge level?” or “How many batteries are left?” AI, battery level?").
3. 🔊 Voice assistant will voice the percentage of charge of each headphone and case (if supported).

⚠️ Note: The function only works on headphones with a Qualcomm chip QCC3040 This is not available for budget models (Redmi Buds 3 Lite.

Indicators on the case: what do flashing lights mean

If you don't have a phone, you can tell the charge level from the lights on the case. Xiaomi uses a standard color scheme, but it can vary depending on the model.

💡 Tip: To know the percentage of charge on the indicator, click the button on the case (if any). For example, in Redmi Buds 4 Active, one click shows the charge of the case, and double - the charge of the headphones.

💡

If the indicator on the case flashes red and white alternately, this is a sign of a malfunction of the battery. Try to reset the headphones (press the button on the case for 10 seconds) or contact the service.

5. Hidden engineering teams (for advanced users)

Few people know, but some Xiaomi models have a hidden engineering menu through which you can get advanced information about the battery, which is suitable for AirDots 3 Pro, FlipBuds Pro and other models on the Qualcomm chip.

How to open the engineering menu:

1. 📱 Put your headphones on the phone.
2. 🔤 In any messenger or notebook, type the command ##36446337## and copy it.
3. 📞 Open the phone keyboard, insert the command and press the call.
4. 🔧 In the menu, find Battery Info or Headset Battery.

📊 You'll see here:

• 🔋 The exact percentage of charge of each headphone and case.
• 📉 Discharge schedule for the last day.
• 🔄 Number of charging cycles (useful for diagnosing battery wear).

⚠️ Warning: Do not change other settings in the engineering menu - this can lead to resetting headphones or loss of communication with the phone.

6. Update of firmware for correct charge indication

If the headphones stopped showing charge levels, the problem could be with outdated firmware. Xiaomi regularly releases updates to correct battery indication errors.

How to update firmware:

1. 📲 Open the Xiaomi Wear or Mi Fit app.
2. 🔍 Go to the section of your headphones. → Settings → Firmware update.
3. 🔄 If a new version is available, click Update and wait until it is completed (don’t turn off the headphones!).

🔧 After updating:

• 🔋 Reboot the headphones (put in the case for 10 seconds, then pull out).
• 📱 Remove them from the list of Bluetooth devices and connect again.

💡

Updating the firmware solves 80% of problems with incorrect charge indication. If after the update the problem remains, check the headphones on another phone to rule out a Bluetooth module error.

7. Alternative methods (if nothing works)

If standard methods don’t work, try these options:

Method 1: Third-party applications

• 📊 Battery Monitor for Bluetooth (Google Play) – shows the charge of any Bluetooth device.
• 🔍 nRF Connect (for advanced users) – allows you to read the technical data of headphones.

Method 2: Connecting to a PC

Some models (such as AirDots Pro 2) can be connected to a computer via Bluetooth and checked in the Device Manager (Bluetooth → device properties section).

Method 3: Calling the headphones

Call the second phone to the connected headphones, and when you call, some models will voice their charge levels (e.g., "70 percent battery").
