How to know the exact charge level on Xiaomi wireless headphones: all ways

Why it is important to track the charge of wireless headphones

Xiaomi’s wireless headphones are not just an accessory, but a full-fledged device with its own battery that requires attention. Controlling the charge level helps avoid suddenly turning off the sound at the most inopportune time: during an important call, training or listening to a podcast. But if wired headphones are enough to look at the screen of the smartphone, then with TWS-models (True Wireless Stereo) is more complex: they have two power sources – the headphones themselves and the charging case.

The manufacturer doesn't always make the indication obvious. For example, the budget models of Redmi AirDots or Mi True Wireless Earbuds Basic 2 do not have a display on the case, and LEDs flash mysterious combinations. In the premium series of Xiaomi FlipBuds Pro or Buddy Bracelet, the situation is better — there are voice prompts and support through the app. But even here users face the non-obvious nuances: why one earphone discharges faster than another or how to distinguish 100% charge from 80% by color of the indicator.

In this article, we will analyze all available methods of checking the charge - from the standard (via the Mi application). Fit/Xiaomi Wear to hidden (or Android or iOS commands, voice queries) and why headphones can show the wrong battery level and how to fix it.

Method 1: Indicators on the case - decoding colors and blinks

The fastest way to estimate charge is to look at the LEDs on the charging case. Xiaomi uses a color scheme, but it differs depending on the model. For example, in Redmi AirDots 3 Pro, white means full charge, and in Mi True Wireless Earbuds 2 it means orange. To avoid confusion, we made a table:

⚠️ Note: If the indicator on the case does not burn at all, this may mean:

• 🔋 Case battery discharged (you need to connect to a power source).
• 🔌 A faulty cable or port USB-C/Micro-USB.
• 💧 Moisture got into the contacts (relevant for models without protection) IP54).
• 🛠️ Charging controller failure (reboot of headphones required).

Method 2: Application Mi Fit/Xiaomi Wear - exact percentages

Xiaomi’s official apps show the charge level of each headphone and case separately, which is the most reliable method, but it doesn’t work with all models, for example, the Redmi AirDots of the first version in Mi Fit are displayed as “battery-free device”, and FlipBuds Pro show detailed statistics, including battery life.

Instructions for setting:

1. Install the app: 📱 For Android: Mi Fit or Xiaomi Wear (depending on the model). 🍎 For iOS: Mi Fit (support limited).

Bluetooth

Battery

Charge.

Update Mi Fit/Xiaomi Wear to the latest version

Reconnect the headphones in Bluetooth settings

Reset the headphones to factory settings (click the button on the case for 10 seconds)

Check model compatibility with the application (see table below)-->

🔍 Compatibility of models with applications:

• ✅ Full support: FlipBuds Pro, Buddy Bracelet, Redmi Buds 4 Pro.
• ⚠️ Partial: Mi True Wireless Earbuds 2 (case level only).
• ❌ Unsupported: Redmi AirDots (1 gen), Mi Basic 2 (Indicators only).

💡

If the headphones are connected but the charge is not displayed, try turning off battery saving for the Mi Fit app in your smartphone settings. On Android, this is done in the Settings section. → Annexes → Mi Fit → Battery → No restrictions.

Method 3: Voice Assistant (Alice, Google Assistant, Siri)

If you don't have an app on hand, you can tell the charge using voice commands, which works on Android and iOS, but requires pre-setting.

For Android (Google Assistant):

1. Activate the assistant with your voice or hold the Home button.
2. Say, “What’s the charge on my Xiaomi headphones?” or “Show me the battery level of the Redmi Buds.”
3. If the assistant doesn’t recognize the device, check if the headphones are connected via Bluetooth and if the option to Show Battery Notifications in Mi Fit settings is enabled.

For iPhone (Siri):

• 🍏 Siri only supports headphones with a chip W1/H1 (For Xiaomi, this method doesn't work directly, but you can use a workaround:
• Install the Battery Bot app or Bluetooth Battery Monitor from the App Store.
• Connect the headphones and open the application - it will show the level of charge in the widget.

For Alice (Yandex):

Alice can only show charge for devices that support Yandex IoT. Xiaomi headphones are not on this list, but if you have a smart speaker Yandex, you can say:

Alice, ask Mi Fit what my headphones are.

To do this, you need to pre-link Xiaomi and Yandex accounts in the Mi Fit settings.

Method 4: Widgets and notifications on a smartphone

On Android, the headphone charge level can be displayed directly in the notification bar or through widgets.

• 📲 The headphones support Bluetooth Low Energy protocol (BLE).
• 🔄 Synchronization with Mi Fit enabled.
• 📱 The smartphone runs on Android 8.0+ (iOS requires third-party applications).

How to configure the display of charge in notifications:

1. Open Settings → Connected devices → Bluetooth.
2. Find your headphones in the list and tap the gear (⚙️) near-name.
3. Enable the option to Show battery level (name may vary).

If this option is not available, install the widget:

1. Long press on the main screen → Widgets.
2. Find the Mi Fit widget or Devices (at MIUI).
3. Drag it on the screen and select your headphones.

Method 5: Hidden commands for Android (ADB and engineering menu)

For advanced users, there is a way to get data about the battery directly through the ADB (Android Debug Bridge.This is true if the headphones don't display charge in the app but are connected to a smartphone.

Instructions:

1. Enable Developer Mode on Smartphone: Go to Settings → About the phone, tap 7 times on the version MIUI (or the assembly number on other firmware).

Settings → Additional → For Developers

USB debugging

ADB Tools

adb shell dumpsys battery

In the output, find the lines with the level and the device. If the headphones support data transfer, there will be information about them.

⚠️ Attention: This method requires technical knowledge. Wrong commands ADB This can cause your smartphone to malfunction. Don't use it unless you're sure you're doing it.

💡

Method ADB It is suitable only for diagnosis – it will not show the charge of the headphones in real time, but only confirm whether they transmit data about the battery to the smartphone.

Method 6: Sound prompts and voice notifications

Some Xiaomi models voice the charge level when connected or removed from the case, for example, FlipBuds Pro says, “Hearphone battery – 70 percent”, and Redmi Buds 4 Pro emits different number of audio signals:

• 🔔 1 signal - charge 0-30%.
• 🔔🔔 2 signals - 30-70%.
• 🔔🔔🔔 3 signals - 70-100%.

🔊 How to turn on voice prompts:

1. Open the Mi app Fit/Xiaomi Wear.
2. Choose your headphones. → Settings → Voice prompts.
3. Turn on the battery level option.

If the clues don't work:

• Check the language of the voice assistant (should match the system).
• Update the headphone firmware through the app.
• Reset the headphone settings (press the button on the case for 15 seconds).

Method 7: External chargers with display

If none of the above methods work, you can use external methods. USB-These are the devices that show the current, voltage and battery capacity when you charge:

• 🔌 Xiaomi USB Tester (shows mAh and V).
• 🔋 Baseus Digital Display Charger (with support) USB-C).
• ⚡ ORICO USB Tester (with the function of recording statistics).

How to use:

1. Connect the tester to a power source (charging or power bank).
2. Put the tester in with the headphone case.
3. The screen will show the current charging current. Multiply it by time (in hours) and get an approximate capacity in mAh.

⚠️ Attention: Testers show charging current, not battery level. To know the percentage, you need to know the initial capacity of the battery case (for example, 400 mAh in Redmi AirDots 3:

(Charging Current in mA × Time in Watch) / Battery Capacity × 100% = Charge Level

Frequent problems and their solutions

Sometimes the headphones are not showing the right level of charge or they are quickly discharged, and here are the most common reasons and ways to eliminate them:

If none of these methods worked, there might be a problem with the hardware.

1. Contact the Xiaomi Service Center (check the warranty).
2. Try replacing the battery (for models with removable battery).
3. Buy a new case (they are often sold separately).
