How to know exactly what Xiaomi headphones are charged: instructions with photos and videos

You put Xiaomi headphones in your case, plugged it into your charger -- but how do you know it's over? Some models signal with LED, some make sound, and some don't show any obvious signs at all. In this article, we'll look at all the ways to check the charge for different Xiaomi/Redmi headphone lines, including hidden features and typical user errors.

The thing about wireless headphones is that they have two parts: the battery of the case itself and the mini-battery in each headphone, and many people confuse the case indication with the charge of the headphones, and as a result, they go without sound at the most inopportune moment, and we will show you how to distinguish one from the other and why sometimes Xiaomi Buds do not charge to 100% even after hours on charging.

In the article you will find:

• 🔋 Visual signs of full charge (color indicators for each model)
• 📱 Software methods of verification through the application Mi Home/Xiaomi Wear
• 🔊 The sound signals that the headphones give when charging is completed
• ⚡ Hidden button combinations for forced battery level check
• ❌ Common errors that cause the headphones to not charge until the end

1. Indicators on the case: decoding of colors and blinks

The main way to determine the charge is to look at the LED indicator on the front of the case. However, Xiaomi does not have a single standard: the color scheme differs depending on the model and year of release. Below is the current table for popular lines (data for 2026).

Attention! In models older than 2020 (like the AirDots Basic), the indicator can only be turned on when connected to the power - if you turn off the cable, the LED will go out regardless of the charge level. This is normal behavior, not a breakdown.

Another nuance: headphones with a transparent case (for example, Xiaomi Buds 3T) inside you can see an additional indicator on each headphone. If it burns red, charging is going, green, charge is complete, but you can only see it in the dark or in bright light.

2. Sound and tactile signals: what do they mean

Many Xiaomi models not only glow, but also make sounds or vibrate when charging is finished. These signals are easy to miss if the headphones are in your bag or on a table in another room.

• 🔊 One short signal when connected to charging – the beginning of the process (all models).
• 🔊 Two short signals – headphones are 100% charged (Buds 4 Pro, FlipBuds Pro).
• 🔊 Long signal. + Case vibration – full charge of the case and headphones (Redmi Buds) 5A).
• 🔊 Voice Assistant (in Chinese/English): Battery full – Xiaomi-enabled models only AI.

⚠️ Attention: If the headphones emit intermittent signals (3 short – pause – 3 short), this means a charging error. Causes: damaged cable, dirt on the case contacts or a battery failure. Try to wipe the contacts with alcohol and use another cable.

Redmi AirDots 3 Pro and later have a hidden feature: if you tap the touchpad three times while charging, the voice assistant will tell you the current battery percentage. This option only works when you connect to a Xiaomi smartphone with MIUI 13+ firmware.

💡

If the headphones do not emit sounds when charging, check the settings in the Mi Home app: go to Device → Sound settings → Charging signals and turn on the option.

3.Verification through the app: Mi Home vs Xiaomi Wear

The most accurate way to know the charge level is to use the official app, but there are pitfalls here: not all models are supported in the Mi Home, and Xiaomi Wear sometimes displays incorrect data. Let's take a look at the steps.

Instructions for Mi Home (suitable for most models):

1. Open the app and make sure the headphones are connected to the phone.
2. Go to the Devices section → Headphones.
3. On the main screen of the device will be the indicator of the charge of the case and each headphone separately.
4. Click on the battery icon – detailed statistics will open (charging time, cycles, temperature).

Instructions for Xiaomi Wear (for new models):

• 📲 Go to My Devices and select Headphones.
• 🔋 Click on Battery Status – here is the real-time percentage of charge.
• ⚙️ You can enable full charge notifications (Battery Alert option).

⚠️ Note: If the app displays a charge of 100%, but the headphones discharge quickly - this is a sign of battery wear. Check the number of charging cycles in the statistics: if the value exceeds 500, it is time to change the battery.

4. Hidden Verification Methods: Button Combinations and Engineering Menu

If the indicators don't work and the app doesn't connect, you can use hidden commands, which are suitable for power users and require care.

Method 1: The combination of buttons on the case

For Redmi AirDots 2/3 and Xiaomi Buds 3 models:

1. Open the case and press the button on the back for 10 seconds.
2. The indicator will flash red-green-blue - this means that the case has switched to diagnostic mode.
3. Close the case and open again – now the indicator will show the real level of charge (color depends on the model).

Method 2: Engineering menu (for stitched models only)

If your headphones support ADB-commands (e.g. Xiaomi Buds 4 Pro), you can get data about the battery through the computer:

adb shell dumpsys battery

In the answer, look for the lines:

• Level: 100 is full charge.
• Status: 2 – Charging is complete.
• Health: 2 – The battery is in good condition.

5.Typical Mistakes: Why Headphones Don't Charge to 100%

Many users are faced with the fact that Xiaomi headphones do not reach 100% or quickly discharge after disconnection from the network.

Top.-5 causes of incomplete charging:

• 🔌 Unoriginal cable – cheap cables do not provide the right current (must be) ≥ 5V/1A).
• 🧲 Dirt on the contacts - oxidation or dust interrupts charging. Wipe the contacts with a cotton swab with alcohol.
• 🔋 Battery wear and tear - after 300-500 cycles, the capacity drops by 20-30.
• 📱 Background processes – if the headphones are connected to the phone while charging, they waste energy on synchronization.
• ❄️ Low temperature - at < +10°C Lithium polymer batteries charge more slowly.

💡

If the headphones only charge 80 to 90 percent and they discharge quickly, that's the controller's protective mode, which is activated when the battery wears out or overheats. Solution: let the headphones cool down for 30 minutes, then recharge.

How to check the charging current:

Use the Ampere (Android) or USB Meter (iOS) app:

1. Connect your headphones to the phone through OTG-cable.
2. Launch the application - it will show the charging current (normal: 300-500 mA).
3. If the current < 200 mA is a problem in the cable or power supply.

So for clarity, we've created a comparison table with video examples for popular models, and you can see the full charge time, which depends on the battery capacity and the firmware version.

Tip: If you often lose your case or forget about charging, set up notifications in Mi Home.

1. Open the app and select headphones.
2. Go to Settings. → Notifications.
3. Enable the option to Notify about low charge (threshold can be set to 20% or 30%).
