How to determine that Xiaomi headphones are fully charged: all the ways for different models

Xiaomi’s wireless headphones are some of the most popular on the market, thanks to a combination of price, sound quality and battery life. But even for power users, there is sometimes confusion: how do you know for sure that a device is 100% charged? Especially if you’re looking at models with minimalist designs that don’t have a traditional LED battery level indicator.

In this article, we’ll look at all the different ways you can test your charge, from standard indicators to hidden features in your apps, how Redmi AirDots, Mi True Wireless Earphones and other lines differ, why headphones sometimes lie about 100% charge, and what to do if the indication doesn’t work properly, and what to do if the 2023+ model’s unique life hack is not described in the official documentation.

1. Standard charge indicators: what do colors and blinks mean

Most Xiaomi headphones use LED lights to display charge status, but their logic may vary depending on the model and year of release.

• 🔴 Red constant light – charge less than 20%, requires a connection to a power source.
• 🟠 Orange/yellow light – battery level from 20% to 80% (on some models – up to 60%).
• 🟢 Green constant light is 80 to 100 percent charge. On the Redmi Buds 4 Pro and later, it can mean 100%.
• 🔄 Blinking white/blue headphones in pairing mode (not to be confused with charge!).
• ⚡ Blinking red – critical battery level (less than 5%) or charging error.

Importantly, the Mi True Wireless Earphones 2 and Redmi AirDots 2 have a green light at 90% charge, not 100%, to speed up the process, the last 10% can charge longer because of battery protection, and you'll need a mobile app to know the percentages.

Also pay attention to the behavior of the indicator when connecting to charging:

• 🔋 If the LED does not burn at all, check the cable, port USB Maybe the voltage isn't enough (at least) 5V/1A).
• ⚡ If the indicator flashes red 3 times and goes out, it's a signal of a short circuit in the battery.

⚠️ Note: Xiaomi Mi Earphones Basic headphones (wired) do not have an LED on the body. Their charge can only be checked through a notification on the smartphone when connected.

2. Sound signals: what do squeaks and melodies mean

In addition to visual indicators, many Xiaomi models use audio signals to alert them about their charge status, and here is the full list of transcripts (current for firmware 2021-2026):

On Redmi Buds 4 Active and later, you can turn off the audio signals in the Mi Earphones app settings. If you do, focus only on the LED or smartphone notifications.

Interesting fact: in headphones Xiaomi FlipBuds Pro at full charge sounds a unique tune that can not be turned off. It signals 100% charge of both the case and the headphones inside.

💡

If the sound signals are quieter or distorted, clean the earphone speakers with a cotton swab dipped in alcohol, which may not be a charge problem, but a clogging membrane.

3. Checking the charge through the mobile application

The most accurate way to know the battery level is to use the official Mi Earphones app (for Android) or Xiaomi Wear (for iOS), which shows the percentage of charge of each headphone and case separately, as well as battery life.

Instructions for verification:

1. Connect the headphones to the smartphone via Bluetooth.
2. Open the Mi Earphones app (you can download it from Google Play or the App Store).
3. On the home screen, you will see two circles: the left earpiece, the right earpiece and the case (if supported).
4. If percentages are not displayed, update the headphone firmware through the Settings → Software Update section.

An example of the interface for Redmi Buds 4 Pro:

⚠️ Note: On iPhone, the Xiaomi Wear app can show charge with a delay of up to 5 minutes. To update the data, open the case cover or remove / insert the headphones back.

If the app doesn't see the headphones:

• 📱 Make sure Bluetooth is on and the headphones are paired.
• 🔄 Reset the headphones: press the button on the case for 10 seconds (before flashing white).
• 📲 Update the application to the latest version.
• 🔌 Connect your headphones to charge for 5 minutes – sometimes it “wakes up” the Bluetooth module.

4. Hidden functions: how to find out the charge without the application

Not everyone knows, but some Xiaomi models have hidden button combinations that allow you to check the charge without a smartphone, which are not documented, but work on most devices from 2020-2026.

Methods of activation:

• 🎧 For Redmi AirDots 3/Pro: Press the touchpad on both headphones at the same time on 3 The voice assistant will report the level of charge (e.g., "Battery level eighty percent»).
• 🔋 For Mi True Wireless 2: Press the button on the case three times quickly. The indicator will flash green as many times as tens of percent of the charge (for example, 4 blinks) = 40%).
• 📶 For Buds 4 Lite: Hold your headphones to your ear and pinch the sensor for 5 seconds - hear a voice message about the charge.

Unique lifehack for 2023+ models: if you connect your headphones to your PC via Bluetooth, the device properties (control panel → Devices and printers) will display battery levels as a percentage. This works even without special drivers.

Another little-known way to use a voice assistant is to use:

1. Activate Google Assistant or Siri.
2. Say, "What's the charge on my headphones?"
3. If the headphones are connected, the assistant will voice the current percentage.

5.Typical errors: why headphones don't show charge

Sometimes the charge indicators don't work properly, and here are the most common reasons and ways to eliminate them:

If none of the methods helped, try resetting the headphone settings:

1. Put the headphones in the case.
2. Press the button on the case for 15 seconds (before flashing red and white).
3. Wait 1 minute, then reconnect the headphones.

⚠️ Note: After reset, Xiaomi headphones may lose touch with previously paired devices, you will have to reconnect them as when you first use them.

6.How to extend the life of the battery: tips from Xiaomi engineers

To ensure that the charge indicators always show up-to-date information, and the battery lasts longer, follow these recommendations:

• 🔌 Don't keep your headphones on charge for more than 2 hours after reaching 100.
• 🌡️ Avoid overheating: Do not charge headphones at temperatures above 35°C (for example, in the sun or near a heater).
• 🔋 Keep 40-60% charge if you don’t use headphones for longer than a week.
• 📵 Turn off Bluetooth when the headphones are in the case – this reduces background battery consumption.
• 🔄 Calibrate the battery once every 3 months: completely discharge and charge the headphones without interruptions.

Xiaomi engineers also recommend using original cables and power supplies with Quick Charge 3.0 support. Cheap chargers can deliver unstable voltage, leading to battery bloating or false charge rates.

💡

Optimal charging mode for battery life: connect headphones at 20-30% charge and turn off at 80-90%, which reduces the load on the battery and extends its life by 30-40%.
