How to watch the charge of headphones Xiaomi AirDots 2: all ways with explanations

The Charge Definition Problem: Why It Matters for AirDots 2

Xiaomi AirDots 2 wireless headphones (aka Redmi AirDots 2 or Mi True Wireless Earbuds 2 Basic) have been a hit thanks to the price-performance ratio. But even these popular gadgets have a weak spot: an unobvious charge display system. Unlike flagship models (like AirDots Pro 2), there is no case-based display, and standard notifications on a smartphone don’t always work.

Why is it critical? Imagine if you were on a trip, put your headphones in your case, and an hour later they were dead because the case was almost empty. Or vice versa, the headphones show 100% charge, but after 10 minutes they turn off. These are not uncommon, and this is due to incorrect synchronization of data between devices. In this article, we will discuss all the working methods of checking the charge, from basic to little-known.

Let's just warn you, the methods vary depending on the firmware of the headphones, the version of the MIUI on the phone, and even the model of the smartphone. For example, Xiaomi or Redmi with MIUI 12+ displays detailed information, and on iPhones or phones with pure Android - only approximate data. But about everything in order.

Method 1: Standard Notification on a Smartphone (Android/iOS)

The easiest method is to use the operating system's built-in notifications, which works on most devices, but there are nuances.

On Android (especially with MIUI):

1. Open the AirDots 2 case cover next to your smartphone.
2. Wait for the appearance of a pop-up window with the level of charge of headphones and case.
3. If the notification doesn’t appear, check if Bluetooth is enabled and if the headphones are connected to the phone earlier.

On the iPhone (iOS):

• 📱 Notification will appear only at the first connection or after resetting the headphone settings.
• 🔋 Shows only the charge of headphones, the level of the case is not always displayed.
• 🔄 If the headphones were already paired with the phone, try forgetting the device in the Bluetooth settings and connecting again.

Important note: on some firmware (e.g. MIUI 11 and below), the notification may not show the charge of the case.

💡

If the notification does not appear, try rebooting the phone’s Bluetooth module: turn off and turn on Bluetooth in the control panel or restart the smartphone.

Method 2: Voice Assistant (Google Assistant)

Few people know, but voice assistants can show the level of charge of connected devices, which is unstable, but sometimes saves when other methods are not available.

For Google Assistant (Android):

1. Activate the assistant with your voice (OK, Google) or hold the Home button.
2. Say, “Show me the charge of the headphones” or “What charge is AirDots”.
3. If the assistant doesn’t understand, specify: “Show the charge of Bluetooth devices.”

For Siri (iPhone):

• 🎙️ Say, Hey Siri, what a charge my headphones have?»
• 🔋 It only works if the headphones are currently connected.
• ⚠️ Often shows data with a delay of up to 5-10 minutes.

This method does not show the charge of the case, only the headphones themselves, and it may not work if the headphones are connected to another device (for example, a laptop).

Method 3: Indicators on the case - decoding blinking

The Xiaomi AirDots 2 case is equipped with an LED that signals the status of charge, but its behavior depends on whether the headphones are connected to the phone and whether the case is closed.

AirDots 2: Case indicator shows the charge only when charging, and if the case is not connected to the network, the LED does not burn at all, even if the charge is running out, which often leads users astray.

To check the charge of headphones through the indicator:

Get both earphones out of the case.|Close the case lid.|Press and hold the button on the case for 3 seconds.|Count the number of flashings (1 blinking) = 30% charge)-->

⚠️ Warning: If the indicator flashes red 5 times in a row, it is a signal of a critically low case charge (less than 5%), in which case the headphones may not charge even when connected to the network.

Method 4: Monitoring applications (Mi Fit, Mi Home, third-party utilities)

The official applications from Xiaomi should theoretically show the charge of headphones, but in practice this does not always work.

1. Mi Fit/Zepp Life (for Android/iOS):

• 📲 Supports AirDots 2, but only if connected to your phone via Bluetooth.
• 🔋 It shows the charge only headphones, the case - no.
• ⚙️ Path: Open the app → Profile → Devices → AirDots 2.

2. Mi Home (Android only):

• 🏠 It works unstable, often does not see headphones.
• 🔄 Requires a link to a Xiaomi account (Chinese or global version).
• 📊 If the headphones are displayed, the charge is shown in percentage.

Third-party utilities:

• 🛠️ Battery Monitor for Bluetooth (Android) – shows the charge in real time.
• 📊 AirBattery (iOS) – an alternative to iPhone, but requires a paid subscription.
• ⚠️ Risk: Some apps request access to personal data. check reviews before installing.

Important: official Xiaomi apps often conflict with each other. If the Mi Fit and Mi Home are installed simultaneously, the headphones can only appear in one of them.

💡

Third-party apps can show more accurate data than standard notifications, but require a constant Bluetooth connection and drain the phone’s battery.

Method 5: Alternative methods (for power users)

If none of these things work, there are some other solutions that are out of the box, and they require additional action, but sometimes they are the only way out.

1. Connection to a PC or Mac:

• 💻 Headphones are displayed as a Bluetooth device in Device Manager (Windows) or System Information (Mac).
• 🔋 Some utilities (such as Bluetooth Battery Monitor for Windows) can read the charge level.
• ⚠️ It doesn’t work on all versions of headphones.

Resetting headphone settings:

If the charge data is not displayed correctly (for example, always 100%), the reset will help:

1. Put both earphones in the case.
2. Press and hold the button on the case for 15 seconds until the indicator flashes red and white.
3. Connect the headphones to the phone again.

3. Check through the engineering menu (Android only):

On some Xiaomi smartphones, you can see technical information about connected devices:

#4636## → Information about the battery → Bluetooth devices

⚠️ This method does not guarantee accuracy and may not work on newer versions. MIUI.

Comparison of methods: which one to choose?

To make it easier for you to navigate, we have compiled a comparative table of all methods with an indication of their pros and cons:

Recommendation: for everyday use, a combination of standard notification (for headphones) and case indicator (for checking the charge level of the case) is enough. If you want maximum accuracy, use third-party applications.

⚠️ Note: If no method shows charge, it may indicate a malfunction of the battery controller in the headphones or case.
