How to know that wireless headphones Xiaomi AirDots charged: a full guide with photos and videos

Xiaomi AirDots wireless headphones (including AirDots Pro 2, AirDots 3 and Redmi AirDots) have become some of the most popular gadgets in the Mi Ecosystem line. But despite the ease of use, many users are faced with the problem of how to accurately determine if the headphones are fully charged?

In this article, we'll look at all the ways you can check charging, from the standard case indicators to the hidden features in your app, how to tell a full charge from a partial charge, what to do if the light isn't on, and how to avoid typical charging errors, and at the end, you'll find an FAQ with answers to the most common questions.

1. Standard charging indicators on the case

The most obvious way is to look at the LEDs on the front of the charging case. All Xiaomi AirDots models (except the AirDots 3 Pro) use a single-color or two-color indicator that signals charging status:

• 🔴 Red (blinks or burns constantly) – headphones charge (charge level below 80%).
• 🟢 Green/white (burning constantly) – charging completed (100%).
• 🔴🟢 Red. + green (blinking alternately) – charging error (e.g., poor contact).
• ⚪ White flashing (only AirDots 3) – headphones connected to the case, but not charged.

It's important to consider that different models may have different display logic, like Redmi AirDots, which turns green at 90 percent charge, and AirDots Pro 2 only at 100 percent. To make sure you're not mistaken, check the table below.

⚠️ Note: If the indicator on the case does not burn at all, check the cable and power supply. Xiaomi AirDots do not support charging from the device. USB-port 0.5A — Use the original adapter or port USB 2.0 on PC.

2. Sound signals: what do squeaks mean when charging

Many users are unaware that Xiaomi AirDots emits audible signals when you connect to the case and complete charging, which help determine the status without looking at the indicator:

• 🔊 Short high squeak - the headphone connected to the case and began to charge.
• 🔇 Double squeak - charging completed (100%).
• 🔊🔇 Repetitive signal – charging error (e.g. dirt on contacts).

The AirDots 3 Pro and AirDots Pro 2 have more melodic sounds, while the Redmi AirDots have sharper and shorter sounds, and if the headphones don't make any sounds at all, it could mean:

• 🔋 Discharged battery case (less than 5%).
• 🎧 Damaged speakers (check the sound when playing music).
• 🔌 Poor contact between the headphone and the case.

💡

If the charging sounds are annoying, you can turn them off, put the headphones in the case, close the lid, and hold the touchpad on both earphones for 10 seconds, and after you squeak the sounds are deactivated.

3. Charge check via Mi Home/Mi Fit app

The Mi Home and Mi Fit apps (for some models) allow you to track the charge level of the headphones and case in real time, which is especially useful if the indicator on the case broke or its logic is unclear.

To check the charge through the application:

1. Open Mi Home (or Mi Fit for AirDots 3)
2. Go to the Devices section → Headphones.
3. Click on the icon of your AirDots model.
4. In the window that opens, you will see the percentage of charge of the left, right earphone and case.

If the application does not show the charge level:

• 📱 Update the application to the latest version.
• 🔄 Reconnect your headphones via Bluetooth Settings.
• 🔋 Make sure that the case is at least 10% charged (with a lower charge, data may not be transmitted).

⚠️ Note: The Mi Home app updates the charge data with a delay of up to 1 minute. If you just put your headphones in the case, wait 30 to 60 seconds before checking.

4. Visual inspection: how to understand the behavior of headphones

If the indicator does not work, and the application does not connect, you can determine the charging by indirect signs:

• 🔋 The headphones don't turn on when you're extracting from the case, it's under 5.
• 🎵 Sound is interrupted or distorted – charge at 10-20%.
• 🔊 Voice assistant reports low charge (only AirDots 3 Pro).
• 🔄 Headphones spontaneously turn off - critically low charge (less than 3%).

Also, pay attention to the charging time:

• ⏱️ 0-30 minutes charge up to 50%.
• ⏱️ 30-60 minutes charge 50-80%.
• ⏱️ 60-90 minutes – full charge (100%).

In models with support for fast charging (AirDots 3, AirDots Pro 2) 10 minutes in the case give up to 1 hour of battery life.

5 Hidden Features: How to Find Charges Through Bluetooth Settings

On iOS:
