How to check the charging of Xiaomi headphones: all the ways from indicators to hidden commands

Xiaomi headphones are some of the most popular wireless gadgets on the market, but even they sometimes have problems with displaying the charge level. You take the headphones out of the case and they suddenly turn off after 10 minutes? Or the indicator on the case flashes green, but the sound is interrupted? In this article, we will analyze all possible ways to check charging, from standard to hidden, which are not described in the official instructions.

The problem is that different Xiaomi models (from the budget Redmi AirDots to the flagship Xiaomi Buds 4 Pro) use different methods of display. ADB-We've collected up-to-date data for 2026, including workarounds for devices without official support.

Important: if your headphones are running too fast, the problem may not be the display of charge, but the wear and tear of the battery. At the end of the article, there is a section on the diagnosis of such cases.

1. Standard indicators on the case and headphones

The most obvious way is to use built-in LEDs, which are located on the front of the case or inside most Xiaomi models (e.g. Xiaomi Buds 3T Pro).

  • 🟒 Green (permanent) – charge case and headphones 60-100%.
  • 🟑 Yellow/orange (permanent) – Case charge of 20-59%, headphones can be fully charged.
  • πŸ”΄ Red (permanent) – Case charge less than 20%, headphones discharged.
  • πŸ”„ Blinking white – headphones are connected to the device (not a charge indicator!).
  • ⚑ Flashing red – charging error (check contacts or cable).

Some models (such as the Redmi Buds 4 Active) have the indicator hidden inside the case and only visible when opened, sometimes you need to press the button on the case or take out the headphones to activate it.

⚠️ Warning: If the indicator flashes red for more than 10 seconds, it is a sign of a short circuit in the battery.

To accurately determine the level of charge on the indicator, use this table:
