Charging indicators: what do colors and flashes mean

The display system on Xiaomi headphones is intuitive, but different models can have nuances. Let's understand what the colors and flashing modes of indicators on the case and headphones mean.

Colors of the indicator on the case

• 🔴 Red (burns constantly) - case discharged (0-20%), charger.
• 🟠 Orange (burns constantly) - there is a charge case.
• 🟢 Green (burning constantly) – the case is fully charged.
• ⚪ White (flashing) - there is a charge of headphones inside the case.

Headphone indicators

Some models (such as Xiaomi AirDots 3 Pro) have small LEDs on the headphones themselves that signal status:

• 🔴 Red (blinks when extracted from the case) – low charge (less than 10%), charging is required.
• ⚪ White (Blinking) - Headphones ready to pair.
• 🟢 Green (blinks) – High charge level (more than 60%).

If the indicator on the case flashes red and green alternately, it indicates a charging error.

• Poor contact between headphones and the case;
• Failure of the battery of one of the headphones;
• Software failure of the power controller.

In such cases, try:

1. Remove and re-insert headphones in the case;
2. Clean the contacts with an alcohol napkin;
3. Reset the headphone settings (for some models, hold the button on the case for 10 seconds).

Frequent charging errors and how to avoid them

Even experienced users sometimes make mistakes that shorten the life of the headphone battery, and here are the most common ones and ways to prevent them.
