How to find out the charge of Xiaomi wireless headphones: all the ways from indicators to hidden functions

Xiaomi wireless headphones are some of the most popular gadgets on the market, thanks to a combination of price, sound quality and functionality. But even experienced users have a question: how to accurately determine the battery level, especially when the indicators on the case flash in an unobvious way. Unlike smartphones, where the percentage of the battery is always in sight, with headphones it is increasingly difficult: the manufacturer often hides this information in the non-obvious menus or does not display it at all.

In this article, we will look at all the available ways to check the charge, from the standard (via the mobile app and voice assistant) to the little-known (hidden codes and engineering menus). You will learn how the indicators differ from the models of Redmi Buds 4 Pro, Xiaomi Buds 5 and older versions, why sometimes the data is not displayed, and what to do if the headphones are discharged at the most inopportune moment.

1. Standard method: indicators on the cover

The most obvious method is to look at the LEDs on the front of the charging case, but there are a few pitfalls here:

• 🔴 One flashing indicator – case charge below 20%, headphones may not charge.
• 🟡 Two indicators - level of 20% before 50%. Enough for you. 1-2 headphone-load.
• 🟢 Three or four indicators, charge above 50 percent. You don't have to worry about recharging.
• ⚪ White flashing light – headphones are connected to the case and charged (at models Xiaomi Buds) 3T Pro and newer).

It is important to note that different models have different indicators and their logic, for example, Redmi AirDots 3 has only two LEDs (red and green), and Xiaomi FlipBuds Pro has four, and they display charge in increments of 25%.

⚠️ Note: If the indicators on the case do not burn at all, this can mean not only complete discharge, but also sticking contacts (a common problem after moisture is ingested.

2.Mi Home / Xiaomi Wear app: exact percentage of charge

The official Mi Home app (or Xiaomi Wear for new models) is the most reliable way to know the exact charge level.

1. Connect the headphones to the smartphone via Bluetooth.
2. Open Mi Home → go to Devices → select your headphones.
3. On the main screen of the device will appear indicator charge case and each headphone separately (if the model supports this function).

Older models (e.g. Redmi AirDots) can only display the case charge in the app, in which case try an alternative method:

Update the application to the latest version|Reconnect the headphones to the phone|Check if the Bluetooth settings have enabled the “Show Charge Level” function"|Reset the headphones to factory settings (press the button on the case for 10 seconds)-->

⚠️ Note: In the Xiaomi Wear app (for 2023 models)+ The charge data can be updated up to 5 minutes late. If you just put your headphones in your case, wait or manually update the device page by pulling the screen down.

3. Voice assistant: a fast way without apps

If you have a Xiaomi, Redmi or POCO smartphone with MIUI firmware, you can use the XiaoAI voice assistant (or Google Assistant on other Android devices):

1. Activate the assistant with a voice command or hold the Home button.
2. Say, “What’s my headphone charge?” or “Show me the battery level of Xiaomi Buds.”
3. The system will give data on the charge of the case and headphones (if they are connected).

This method only works for models that support the FASTPAIR protocol (e.g. Xiaomi Buds 4 Pro, Redmi Buds 5). If the assistant answers that "cannot identify the device", then your model is not compatible.

💡

On Xiaomi smartphones with MIUI 14+, you can add the headphone charge level widget to the home screen. To do this, hold your finger in the free space of the screen → “Widgets” → find the “Bluetooth devices” section.

4. Hidden codes and engineering menu (for advanced)

Few people know, but some Xiaomi headphones have a hidden engineering menu where you can see detailed information about the battery, which is suitable for models on a Qualcomm chip (for example, Xiaomi Buds 3 Pro, FlipBuds Pro).

Instructions:

1. Connect the headphones to your smartphone.
2. Open the dialing app (as if you were calling).
3. Enter the code: ##3644633## (for models on Qualcomm) or ##4636## (universal).
4. In the menu, select Battery Information.

Here you'll see:

• 🔋 Level - current level of charge in percentage.
• 🔌 Voltage - battery voltage (normal: 3.7–4.2V).
• 🔄 Temperature: Battery temperature (critical value: above 45)°C).

⚠️ Warning: Do not change any settings in the engineering menu unless you are sure of their purpose! Incorrect settings can lead to rapid discharge or even damage to the battery.

Third-party applications: alternative for all models

If the standard methods don't work, you can use third-party utilities.

• 📱 Battery Bot Pro – shows the charge of headphones in the status bar (requires Android 8.0)+).
• 🔍 AirBattery - specialized on wireless headphones (supported by Xiaomi, Redmi, Haylou).
• 🛠️ MaterialPods – for models with a chip BES2000 (For example, Redmi Buds 3 Lite).

Example of working with AirBattery:

1. Download the app from Google Play.
2. Connect the headphones via Bluetooth.
3. Open the application - on the main screen will appear the percentage of charge of the case and each headphone.

⚠️ Note: Some apps (such as Battery Monitor) require special permissions to be enabled in Android settings: → Annexes → Special access → Display over other windows.

6. How to check the charge without a smartphone (emergency situations)

If you do not have a phone at hand, but you need to find out the charge level urgently, use these methods:

• 🔊 Audio signal: most Xiaomi models, when connected to the case, receive a voice message in Chinese or English: “Battery low” (charge is low) or “Battery full” (fully charged).
• 🔄 Discharge test: Turn on your headphones and leave them to work at maximum volume. 10-15 minutes - charge critically low.
• 🔋 Weight of the case: a fully discharged case weighs on 1-2 less than a gram charged (can be checked on kitchen scales).

For models with wired charging (for example, Redmi AirDots), you can use a multimeter:

1. Put the multimeter in voltage measurement mode (DC, 20V).
2. Connect the probes to the case contacts (polarity is not important).
3. Voltage 3.7-4.2V means full charge, below 3.4V - discharged.

💡

If Xiaomi headphones do not hold a charge for more than 2-3 hours, this is a sign of battery wear.The average battery life in wireless headphones is 2-3 years (300-500 charging cycles).

7. Frequent problems and their solutions

Sometimes the charge data is not displayed correctly or not at all.

If none of the methods worked, there may be a problem with the hardware, in which case, contact the Xiaomi service center - replacing the battery in the case or headphones will cost 800-1500 rubles (depending on the model).
