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

Why Xiaomi owners are often confused with headphone charging

Xiaomi's wireless headphones are some of the most popular on the market, thanks to their combination of price and quality, but even experienced users have difficulty determining their charge levels. TWS-There is no display, the manufacturer uses a combination of lights, sound signals and program notifications — and it’s not always easy to figure them out.

Complicating the problem is that different models (Redmi AirDots, Mi True Wireless Earphones, Buds 3/4 Pro) have excellent display systems. For example, in AirDots 2, the LED flashes red when discharged and goes out when fully charged, and in Buds 4 Pro, color gradient lighting is used.

In this article, we’ll look at all the ways to test your charge, from basic (visual indicators) to advanced (Mi Home app, hidden voice prompts), and why sometimes headphones show 100% charge in a case, but discharge in 10 minutes of use – and how to avoid this.

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

The main way to determine the charge is to look at the LED light on the front of the case. Xiaomi uses a standard color scheme, but it may vary depending on the model. Here's the universal table for most devices:

⚠️ Attention: In Mi True Wireless Earphones 2 Basic and Redmi AirDots S, the indicator goes out completely when the case reaches 100% charge. This is often confusing - users think the device has broken. In fact, the lack of backlight in this case means the successful completion of the charge.

To check the charge of the headphones themselves (not the case), take them out of the case. If the headphone indicator lights up white for 1-2 seconds and goes out, they are charged. If it flashes red, the battery level is below 20%.

2. Sound signals: what do squeaks mean when charging

In addition to lights, Xiaomi headphones use audio cues that turn on automatically when connected to a briefcase or power source.

• 🔊 One short squeak when placing headphones in the case - charging has begun (battery level) < 80%).
• 🔊 Two short squeaks – headphones are 100% charged (in the case).
• 🔊 Long squeak (1-2 seconds) when connecting the case to charging - the process of charging the case began.
• 🔊 Three short squeaks when removing headphones - the case battery is discharged below 10%.

⚠️ Note: In Buds 4 Pro and later, you can turn off the audio signals in the Mi Home app settings. If the squeaks suddenly disappear, check the Settings section. → Sounds and vibrations → Charging signals.

One important thing is that the sounds only work when you first connect the headphones to the case after you remove them, and if you take them out several times and put them back on, the signals may not play back, which is normal.

💡

If the headphones do not emit sounds when charging, try to reset them to the factory settings: press the button on the case for 10 seconds (before flashing red and white).

3. Check the charge through the Mi Home app

The most accurate way to know the percentage of charge is to use the official Mi Home app (available for Android and iOS), which shows separately the battery level of the left earbud, right earbud and case.

1. Install Mi Home from Google Play or App Store.
2. Sign up or sign in to your Xiaomi account.
3. Click Add Device (+) → select Headphones category.
4. Follow the instructions on the screen (usually you need to open the case cover and hold the sync button for 3-5 seconds).

Once connected, a charge-indicator card will appear on the home screen.

• 📊 View battery life in hours (calculated based on current charge level).
• 🔄 Update the headphone firmware (if a new version is available).
• 🔇 Set up charging sound signals.
• 🎧 Check the status of the connection (codec) AAC/SBC).

⚠️ Note: In some regions (e.g. Europe), the app can display a charge with a delay of up to 5 minutes. If you just put your headphones in the case and the percentage has not changed, wait or update the data manually (pull the screen down).

4. Hidden ways: voice assistant and smartphone notifications

Few people know, but Xiaomi headphones (starting with AirDots 3 Pro) support voice notifications about the charge level.

1. Connect the headphones to your smartphone.
2. Open Mi Home → Select headphones → Voice settings
3. Enable the Battery Notification option.

Now, when connected to a case or power source, the voice assistant will say, “charge level – 100 percent” or “charging is complete.”

Another life hack is notifications on a smartphone, and on Android (version 10+), when you plug in the headphones, you get a pop-up window with a percentage of charge in the status bar, so that it shows up:

• 📱 Go to Settings. → Connected devices → Headphones.
• 🔧 Enable the option to Show the charge level.
• 🔔 Allow notifications for the Bluetooth app.

On the iPhone, a similar feature works through the Battery widget (add it to the home screen).However, Apple restricts access to detailed information about the charge of accessories, so you will only see the total percentage without dividing into case and headphones.

Connect your headphones to Bluetooth

Open Mi Home or Bluetooth settings

Check the battery level notification

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

Sometimes users are faced with the fact that Xiaomi headphones charge only up to 80-90%, and then the process stops.

⚠️ Note: If Buds 3 Pro or newer headphones charge slowly (more than 2 hours to 100%), check the power supply.These models support fast charging (up to 50% in 15 minutes), but only when using an adapter with power. 18W+. Charging from USB-port (5W) It will take 3-4 times longer.

Another common mistake is using unoriginal cables, cheap wires may not provide stable voltage, which makes Xiaomi's charge controller artificially limit current. Always use a kit cable or a certified USB-C labeled 5A.

1. The state of contacts in the case (cleanliness, no damage).

2 Power supply (for fast charging requires 18W+).

3. firmware version (update via Mi Home).

If it doesn’t help, just contact the service.-->

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

Xiaomi Support Staff Share Recommendations for Battery Care TWS-Headphones (source – official forum Mi Community):

• 🔋 Avoid full discharge. Optimal range is 20-80%. Constant discharges to 0% reduce battery life by 30%.
• 🔥 Do not charge at high temperatures. If the case is heated (for example, lying in the sun), let it cool to room temperature.
• ⚡ Use the original cable. Uncertified wires can produce unstable voltages, leading to degradation of the elements.
• 🔄 Once a month, perform a full cycle (discharge-charge up to 100%) to calibrate the controller.
• 🚫 Don't keep your headphones empty. If you haven't used them for more than a week, charge them up to 50% and turn them off.

You pay special attention to storage, and if you leave your headphones in your case for six months without recharging, the battery can fail.

• Temperature: 10-25°C.
• Humidity: up to 60%.
• Storage charge level: 40-60%.

⚠️ Note: Xiaomi earphones use lithium polymer batteries that degrade even without use. The average lifespan is 3-4 years (or 500 charging cycles), after which the capacity is reduced by 20-30%, and the headphones will have to be charged more often.
