Owning a modern wireless headset from the Chinese giant is comfort that is quickly becoming familiar. However, like any portable device, True Wireless headphones require regular recharging. The situation when music suddenly stops from the dead battery at the most inopportune moment is familiar to many users of the Mi Home ecosystem. Fortunately, the company's engineers have provided many ways to control power consumption, from simple light indicators to complex software widgets.
The verification method depends not only on the specific model of your gadget, whether it is Mi True Wireless Earbuds Basic 2 or the flagship Mi Air 2 Pro, but also on the smartphone operating system. Android device owners have a wider arsenal of tools thanks to deep integration with MIUI, while iOS users often have to resort to third-party solutions or rely on basic Bluetooth functions. Understanding these nuances will allow you to always stay informed about the state of the battery.
In this guide, we will take a look at all the existing ways of monitoring the battery, we will look at standard system notifications, the functionality of specialized applications and the visual signals of the case itself. The accuracy of data from different sources can vary, so it is important to know which indicator to trust the most in a critical situation.
Visual indication and LEDs on the case
The fastest and most reliable way to understand how much power is left is to look at the physical interface of the charging case.Virtually every model, from the budget Redmi Buds to the premium Mi Buds. 3T Pros, equipped with LED lights. LED-The lamp is located on the front panel or inside the headphone compartment. The color of the glow and the flashing mode carry a specific meaning load that must be correctly interpreted.
In most cases, the logic of the indicator is standardized, but there may be exceptions depending on the year of release of the device. For example, when you open the case cover, an LED lights up to show the charge of the case itself. If you pull out the headphones, the indicator can briefly display their current energy level.
Color indication decoding
To understand your device’s behavior accurately, you should refer to the specification of a particular model, and the following is a table with typical values for popular series:
| Model headphones | Location of the indicator | The meaning of red light | The meaning of white/green light |
|---|---|---|---|
| Mi True Wireless Earphones 2 Basic | Front of the case. | Charge < 20% | Charge > 20% |
| Redmi Buds 3 Lite | Inside the case | Mistake or discharge | Normal work. |
| Mi Air 2 SE | Front of the case. | Low charge. | Full charge. |
| Mi Buds 3T Pro | Front (hidden) | Critical level | Enough energy. |
If you put your headphones in your case, the light flashes red often, it could indicate a contact problem or a deep discharge that requires long-term recovery, and visual monitoring becomes the primary diagnostic tool.
Use of system widget in MIUI and HyperOS
Owners of Xiaomi, Redmi and POCO smartphones have a unique advantage - deep integration of accessories into the MIUI shell or the new HyperOS. To display the charge level directly on the desktop or in the notification curtain, you do not need to install additional software.
To activate this feature, you need to do a few simple things: first make sure the headphones are paired with the phone. Then on the desktop, look for the "Hearphones" or "Bluetooth" widget. In some versions of the firmware, it may be called "Mi True Wireless." After adding the widget to the screen, every time you open the case lid next to the phone, the widget will display the percentage of charge of the left and right earphone, as well as the case itself.
☑️ Customization of the widget MIUI
It is worth noting that for the widget to work correctly in the Bluetooth settings, the MIUI Pop-up Window or similar, depending on the firmware region (Global, Chinese, EEA) must be activated. If the widget shows snippets instead of numbers, try rebooting Bluetooth or reconnecting the device. The system widget is the most energy-efficient way to monitor, since it does not consume the CPU resources in the background.
Mi Wear and Xiaomi Earbuds apps
If a standard widget isn’t enough or you’re using a different brand smartphone (Samsung, Realme, Honor), specialized apps come to the rescue.The main tool for new models is Mi Wear (formerly known as Xiaomi Wear), and older or specific devices may require the Xiaomi Earbuds app. These programs provide detailed statistics not available in the standard Android interface.
Once installed and paired through the app, you get access to the full control menu, and it shows not only the current percentage of charge, but also the history of use, the time from the last charge and the approximate time to full discharge. To access this data, you open the application and go to the device management section. The interface usually shows three separate values: left channel, right channel and case.
💡
The Mi Wear app also allows you to update the firmware of the headphones, which often improves the accuracy of the charge display and optimizes power consumption.
It is important to consider that these applications require a wide range of permissions to work, including geolocation access and background work. Without these permissions, the background battery data update may not work, and you will only see current numbers when you actively open the application. In addition, some features may be limited if the headphones are not original or belong to regional versions other than the application version.
Checking the charge through the Android notification curtain
Modern versions of the Android operating system (starting with version 11) natively support the display of charge of connected Bluetooth devices. This feature is independent of the smartphone brand, whether it is Xiaomi or any other manufacturer. However, to see the percentages, the device must support the Battery Level Profile (BLP) profile, which is relevant for most modern Xiaomi models.
When the headphones are connected, at the top of the screen, in the status bar, a small battery icon may appear next to the Bluetooth icon. You can see more information by lowering the notification curtain down. There often shows a separate media player card or a block of connected devices, where the charge level is graphically or numbers are indicated. If the numbers are not displayed, try clicking on the gear in the curtain and check if the "Show Bluetooth Device Charge" item is activated.
In some cases, especially on custom firmware or stripped-down versions of Android Go, this feature can be hidden, and third-party widgets like Battery Widget Reborn or Battery Sound Notification come to the rescue, which can read data from the system’s Bluetooth stack and display it on the screen in a convenient format. Native support for Android is a versatile solution that does not require the installation of “heavy” applications from Xiaomi.
Voice notifications and audible signals
Many users forget about the built-in voice-activity feature, which can be extremely useful. Xiaomi headphones often feature a module that announces the connection status and charge level in English or Chinese. Phrases like "Power on", "Connected" or "Battery low" help navigate without having to reach the phone.
To activate or deactivate voice prompts, a sequence of touches is often required. For example, in the Mi True Wireless Earphones 2 Basic model, you need to quickly press the touch area of both headphones five times at the same time. In other models, such as the Mi Air 2, voice assistant and notifications are controlled through the Mi Buds app or Mi Wear in the "Voice prompts" section.
⚠️ Warning: Voice notifications consume battery power faster. If you are critical to maximum autonomy, it is recommended to turn off this feature after initial settings.
There are simple beeps, besides voice messages, a quiet beep or a series of tone signals can warn you of low charge, Bluetooth shutdown or out of range, and sound indications are the last line of defense, telling you that time for listening to music or talking is almost over.
Display problems and their solution
It's not uncommon for people to have a phone that's 100 percent charge and 10 minutes later, or the headphones are off, or the percentages are stuck, and this is a common problem of desynchronizing data between the headphone controller and the smartphone, often solved by simple calibration.
Calibration requires completely discharging the headphones before turning them off, then putting them in the case and charging them to 100% without removing them in the process. It is also useful to reset the headphones. This usually requires placing them in the case, opening the lid and clamping the reset button (or taps on the sensors) for 10-15 seconds before changing the color of the indicator. After re-pairing, the percentage of charge should be displayed correctly.
💡
If the percentage of charge is displayed incorrectly, perform a full discharge-charging cycle and reset the headphones to factory settings.
Another reason for the data being incorrect could be the background processes of the system that are stuck, which can be done by cleaning the cache of the Bluetooth application in the smartphone settings or simply restarting the phone itself, and if the problem persists on all devices that the headphones connect to, there may be battery wear, which requires contacting the service.
