How to understand that Xiaomi wireless headphones are charging: a complete guide with photos and videos

Xiaomi's wireless headphones are some of the most popular gadgets in the brand's lineup, but their charging display system often raises questions from users. You put your headphones in your case, plugged in the cable, but how do you make sure that the process is really going? Charging errors can lead to battery discharge at the most inopportune moment, so it's important to be able to recognize all the signals of the device.

In this article, we will discuss all the official and hidden ways to check charging for models Redmi AirDots, Mi True Wireless, Buds and other lines. You will learn how to read light indicators on the case, what sound signals the headphones emit when connected to power, and how to check the charging status through the applications Mi Fit or Mi Home. We will also reveal typical errors that cause the case may not charge the headphones, and what to do in such cases.

1. Light indication on the case: decoding of all signals

The main way to determine whether Xiaomi headphones are charging is to look at the indicator on the case, but its behavior depends on the model and version of the firmware.

⚠️ Note: On Xiaomi Buds 3 Pro and later, the indicator can change color smoothly (gradient from red to green) – this is normal behavior. If the LED flashes red and green alternately, this indicates a charging error (see section 5).

To understand exactly whether the headphones are charging inside the case, do the following:

1. Open the case cover and look at the indicator.
2. If it flashes orange, the headphones charge.
3. If it's green, the headphones are already charged.
4. If the indicator is not responding, check the cable and power supply.

2. Sound signals: what do squeaks mean when charging

Many Xiaomi models emit audible signals at the start and end of charging, which are easily missed if the headphones are in a case next to noisy objects.

• 🔊 One short squeak when placing headphones in the case - the device recognized the connection to the charging contacts.
• 🔊 Two short squeaks after 5-10 seconds – the charging process began.
• 🔊 Long squeak (1-2 seconds) – headphones are fully charged.
• 🔊 Three short squeaks in a row – charging error (for example, contact oxidation or battery failure).

On Xiaomi Buds 4 and later, the audio signals are disabled by default to save energy. To turn them on, go to Settings → Sounds → Charging signals in the Mi Fit app.

If the headphones don't make any noise when charging, it doesn't always indicate a problem.

• 🔇 Sounds disabled in the app settings.
• 🎧 Headphones are discharged to 0% and can not reproduce the signal.
• 🔌 Case does not supply power to headphones (check contacts).

💡

If the headphones don’t make any noises when charging, try resetting them to factory settings: press and hold the touchpad on both headphones for 15 seconds until the indicator flashes red and white.

3. Check charging via the Mi Fit or Mi Home app

The most reliable way to control charging is to use the official Mi Fit or Mi Home apps, which show the exact percentage of charge of both the case and each earphone separately.

1. Connect the headphones to the smartphone via Bluetooth.
2. Open the Mi Fit app (or Mi Home for some models).
3. Go to the Devices section → [Your headphones].
4. The screen will display the level of charge of the case and each headphone.

If the annex shows:

• 🔋 "Charging next to the headphone - the process is normal.
• ⚡ "Connected to power" - the case is charged from the cable.
• ❌ "Not found – the headphones do not contact the case.

⚠️ Note: The Mi Fit app version below 5.6.0 may not have a charging indication for Xiaomi Buds 3 Pro headphones and later.Update the app via Google Play or App Store.

4. How to check charging without an indicator (for models without an LED)

Some Xiaomi models, such as the Redmi AirDots 3 Lite or Mi True Wireless SE, do not have a light indicator on the case.

1. Tactile check: When connecting the case to charging, it should vibrate slightly (on supported models).
2. Bluetooth test: Connect your headphones to your phone. Look at the charge level in the Bluetooth status bar (on Android 11+). If the percentage goes up, you charge.
3. Use of third-party apps: Utilities like Battery Monitor or AccuBattery can show the charging status of accessories.

5.Typical charging errors and their elimination

If Xiaomi headphones don’t charge, the reasons can be both software and hardware.

⚠️ Note: If the Xiaomi case stopped charging after falling or getting moisture, do not try to disassemble it yourself - lithium batteries are located inside, which can ignite if damaged.

🔧 Useful advice for models with Type-C:

💡

If the case is not charged via the original cable, try using a cable from a Xiaomi smartphone with Quick Charge support. Some case models require increased current (1.5A instead of 0.5A) to start charging.

6.How to speed up charging Xiaomi headphones

The standard charging time for Xiaomi headphones is 1 to 2 hours, but it can be reduced.

• ⚡ Use a charger with Quick Charge 3.0 support+ (For example, from Xiaomi or Anker).
• 🔌 Connect the case to USB-port 3.0 on a PC or laptop (they give more current than USB 2.0).
• 📵 Turn off Bluetooth headphones while charging (saves up to 15% of your time).
• 🌡️ Charge at room temperature (20–25)°C) - cold or heat slows down the process.

📊 Comparison of charging time:

⚠️ Note: Do not use chargers with output current more 2A, it could damage the power controller of the case: 5V/1.5A or 9V/1A (for models with support for fast charging).

💡

Using unoriginal low-quality cables can lead to unstable charging or even battery damage. Always check the cable certification (better with a USB-IF mark).
