Owners of wireless headsets from the Chinese tech giant often face a situation where music is abruptly cut off due to a sudden discharge of the device.This is because standard display methods are not always obvious to beginners, especially given the variety of models, from budget Redmi Buds to flagship Mi True Wireless. Understanding exactly how your headset reports the state of the power system is a critical skill for comfortable use of the gadget throughout the day without unpleasant surprises.
There are many ways to get accurate data about the remaining battery capacity, and they depend not only on the model of the ears themselves, but also on the version of the operating system of your smartphone. In this article, we will examine in detail all available methods, from built-in system notifications to the use of specialized applications, you will learn how to quickly assess the life of the work and correctly interpret the signals of LEDs on the case.
First of all, it's worth noting that Xiaomi's ecosystem is designed to integrate accessories as much as possible into the smartphone, synchronization is almost instantaneous after pairing, but data visualization may differ. Some models display information in the status bar, others only when opening the charger lid next to the phone, and it's important to consider these nuances when choosing a control method.
Modern versions of the MIUI and HyperOS shells have advanced audio drivers, which allows you to transfer battery telemetry not only to the main module, but also to each headphone individually, as well as to the case itself. However, if you have a third-party phone or an older version of Android, the functionality may be limited to basic Bluetooth protocol metrics.
System Notifications and Android Status Bar
The easiest and most affordable way to check the remaining power is to look at the lock screen or the top panel of the smartphone. Once the headset is successfully connected, the Android system automatically requests battery data. On devices with a MIUI shell, a miniature picture of the case with a percentage of charge often appears next to the Bluetooth icon.
If you unlock the screen, the notification curtain can display a more detailed widget, which shows the charge level of the left and right earphone separately, which is extremely convenient for diagnosis. Sometimes the system only shows the total percentage, ignoring the difference between channels, which is standard behavior of the HFP (Hands-Free Profile) protocol.
⚠️ Warning: If the notification is missing after the phone restarts, try reopening the case lid next to the smartphone.
In some cases, especially on pure Android or third-party launchers, the detail may be missing, so that the status bar will only show the general icon of the headphone battery. To get accurate figures in such situations, you will need to go to the deep Bluetooth settings menu or use third-party utilities, which will be discussed below.
Indication by LED on the charging case
When the smartphone is far away or the screen is off, the main source of information is the charging case itself. Xiaomi and Redmi use the color coding of LEDs to convey status, usually located inside the case between the seats or on the front panel.
The color of the glow and the flashing mode have a well-defined value that is universal to most AirDots and FlipBuds. Understanding this Morse bar will allow you to not guess, but to know exactly the state of the device. For example, constant white light indicates full charge, while red signals a critical need to connect to the network.
| Color of indicator | Mode of work | Importance of status |
|---|---|---|
| White | It's burning all the time. | 100% charge or close to full charge |
| Orange | It's burning all the time. | Charging process is underway (less than 100%) |
| Red. | Migayette | Low charge, recharging required |
| White | Migayette | Conjugation mode or error |
It should be noted that in some budget models, such as Redmi AirDots, the indication can be simplified to one color. In such devices, the red light when removing the headphones means a critically low energy level, less than 10-15%.
💡
If the indicator does not light up when you open the lid, press and hold the reset button on the case for 1 second - this will forcefully activate the battery status check.
Use of the Xiaomi Earbuds app
For smartphone owners not only of the Xiaomi brand, but also Android and iOS devices, the company has developed a specialized application Xiaomi Earbuds. This software is the key to full control of the headset. It allows you not only to see the exact percentage of charge, but also to adjust the touch control, update the firmware and change the equalizer.
Once installed and first launched, the app will automatically detect the connected headphones, and the main interface displays a large graphical indication of the energy level for the left, right earphone and case, and this is the most detailed monitoring method available to the user.
In addition to visual monitoring, the app provides real-time usage history and battery status information. If you notice one headphone discharges faster than the other, this is where you can see the exact delta as a percentage, and you can activate Find the Device mode through the app, which is useful if you lose your earphone in the room.
☑️ Setup of the Xiaomi Earbuds app
Widgets and screen are always on (AOD)
MIUI and HyperOS shells offer advanced personalization tools that display connected audio devices on the desktop. Widgets allow you to see headphone charges without unlocking the phone or opening the notification curtain, which is especially convenient for models with transparent interface design.
AOD (Always On Display) can also display the status of the headset. If the headphones are connected and in the ears or the case is open next to the phone, the corresponding icons can appear on the screen off, but it is worth remembering that constant use of AOD increases the energy consumption of the smartphone itself.
To add a widget, you need to pinch the empty space on your desktop and select the Widgets menu. In the list, find the Bluetooth section or the specific name of your headphone model. Drag the item onto the screen and it will automatically update in the background, showing current battery data.
⚠️ Note: Widgets may not be updated in real time if the aggressively system optimizes background processes.Add the Xiaomi Earbuds app to the battery saving exception list.
Voice assistants and system commands
Interaction with the headset is possible not only visually, but also in voice. Built-in assistants such as Google Assistant or Xiao AI (in Chinese versions) can voice the status of the device. Although direct commands "how much charge" for third-party headsets may not be available, status is often available through the Quick Settings menu.
Some Mi True Wireless models support voice cues inside the headphones themselves. When extracted from a case or when charged low, a synthesized voice can say, "Battery low" or "Power on." This function depends on the regional version of the headphone firmware and can only be activated via the app.
For advanced users who use ADB (Android Debug Bridge, there is the option to request detailed information via the command line. bluetooth_manager, You can get raw data about connected devices, including signal and charge levels, although interpreting them is harder than looking at a beautiful interface.

Display problems and their solution
It's not uncommon for users to experience a situation where the phone is 100 percent charge and after 10 minutes the headphones are turned off, a phenomenon called "battery calibration," or controller desynchronization, and digital values can "lie" if the device has not been discharged to zero for a long time or if a non-original charger has been used.
To eliminate the display error, it is recommended to perform a full calibration procedure, discharging the headphones and case completely until they stop turning on, then placing them on the original cable and holding them up to 100% continuously without opening the lid.
Problems can also arise from contamination of contacts: oxidation or dust on metal patches inside the case prevents normal transmission of current and data; wipe contacts with a dry cotton swab or an alcohol wipe; often after cleaning, the indication begins to work correctly.
💡
Regular full discharge and charging (every 2-3 months) helps the battery controller recalibrate and show more accurate percentages.
