How to check the charge level of headphones Xiaomi

Modern wireless headphones from Xiaomi and subsidiaries like Redmi have become an integral part of the daily lives of millions of users. Autonomy is one of the key parameters that you pay attention to when buying, but in the process of operation, you often need to quickly assess the remaining battery life.

Unlike wired models, TWS-Headsets (True Wireless Stereo) do not have direct physical contact with the power source during use, so rely solely on software and hardware indicators. The notification system for Xiaomi devices is implemented quite flexibly, but requires understanding the logic of the light indicators on the case and in the headphones themselves. The interpretation of diode blinking can vary significantly depending on the specific model and firmware version.

In this article, we will take a look at all the available energy monitoring methods, from visually evaluating LEDs to using specialized software, how to get the most accurate data on the state of the battery and extend the life of your device, and understanding these nuances will help you plan your music and conversations more efficiently.

Visual diagnosis through case indicators

The fastest and most affordable way to get an estimate of energy levels is to look at the LED light on the charging case. Most Xiaomi models, including the popular Mi True Wireless Earbuds and Redmi Buds series, use color coding. Usually green signals high charge (over 60-70%), yellow or orange indicates medium level, and red warns of the need for urgent recharging.

But don't just rely on color. It's important to pay attention to the mode of operation of the indicator: constant burning or blinking carry different semantic loads. For example, when you open the case cover, the indicator can flash a certain number of times, showing the remaining energy in the case itself, not in the headphones. The algorithm of the diode is often written in the firmware of the device and can be changed by the manufacturer in new revisions.

⚠️ Note: The color indication on the case often shows the charge only of the case itself, and not the headphones embedded in it. To get a full picture, you need to check each element separately or use a smartphone.

If you see a rapid flashing of the red light when the lid is closed, this may indicate a deep discharge or malfunction of one of the contacts. In such cases, it is recommended to wipe the contact pads with dry cloth and leave the case on charging for a long time. Sometimes the system needs a "push" to activate the charge controller after a long downtime.

Indication directly in the headphones

Many users forget that the headphones themselves also have built-in indicators that can provide more detailed information when removed from the case or turned on the device. LED-In some Xiaomi models, such as the Mi Air 2 Pro, the voice assistant can verbally report the charge level in English or Chinese immediately after connecting.

There are several standard scenarios for the behavior of indicators: Single flashing in white usually means a pairing readiness or a normal charge level. If you see a flashing in red inside the ear or on the body, this is a critical signal. The battery is less than 10% dead, and the device will soon shut down.

• 🔴 Red flashing – critically low charge, requires immediate installation in the case.
• 🟡 Orange glow - medium level, about 30-60% container.
• 🟢 Green glow - high charge level, the device is ready for long operation.
• ⚪ White flashing – pairing mode or normal operation at a high charge.

It is worth noting that in fully enclosed models, where there are no visible holes for diodes, the indication may be absent or hidden under the speaker grid. In such cases, relying on visual inspection of the headphones themselves is pointless, and the only sure way is to connect to a smartphone or observe the behavior of the case.

Use of Xiaomi Earbuds and Mi Wear app

The most accurate monitoring tool is the official software. For modern Xiaomi and Redmi headphones, the Xiaomi Earbuds app (formerly known as Mi True Wireless Earbuds) is developed. After connecting the headset to the smartphone and logging into the Mi Account, the app displays detailed statistics.

In the interface, you'll see not only the total percentage, but also the separate values for the left and right earbuds, and for the case, which allows you to identify possible imbalances in battery wear, and it's common for one earbud to run out faster than the other because of usage or cell defects.

And it also allows you to set up voice notifications, so you can activate a feature where the headphones will be able to voice the charge level every time you connect, and you have to go to the device settings inside the app and find the item that's associated with voice prompts, which is especially convenient because it eliminates the need to take out the phone every time you check.

Display of the widget on the smartphone screen

Owners of Xiaomi, Redmi and POCO smartphones running on the shell of MIUI or HyperOS have a unique advantage: the system automatically recognizes the connected headphones of the brand and displays a special widget with a charge level in the notification curtain or on the lock screen. This is a native feature that does not require the installation of additional applications.

To activate or check for a widget, just plug your headphones in and unlock the screen. If the widget doesn't appear automatically, it may be hidden in the interface settings. Go to Settings → Bluetooth, find the connected device, and make sure that the "Show Charge Level" option is active. In some firmware versions, the widget doesn't appear until the first case open next to the unlocked phone.

For users of pure Android devices (not Xiaomi), the widget may not be displayed systemically, in which case it is recommended to use third-party battery widgets or rely on the standard notification in the curtain, which appears immediately after pairing.

Checking the charge on the computer and other devices

If you use headphones to work on a computer, it can be harder to know the exact percentage of charge. Windows and macOS don't always correctly translate Bluetooth headset battery data, but there are ways to get that information.

In Windows 10 and 11, the charge level can be displayed in the Device widget in the control panel or in the quick action curtain, but this function is unstable. A more reliable way is to use third-party software such as Battery Monitor or similar utilities that read data from the Bluetooth HID (Human Interface Device) protocol.

⚠️ Note: When connected to a PC, headphones may not transmit left and right ear charge data separately, displaying only the overall value or charge of the case if it is open.

On Apple devices (MacBook, iMac), the situation is similar: the battery widget in the menu bar can show the level of charge, but for this, the headphones must be pre-coupled. If you switch between iPhone and Mac, the charge data is synchronized through iCloud, which makes the verification process instant and convenient.

Diagnostics of problems with displaying charge

There are situations where the headphones are working but the charge is not displayed or the data is incorrect (for example, 100% and abruptly shut down after a minute), this phenomenon is called the "memory effect" or desynchronization of the controller. The first step should always be to calibrate the battery.

To perform calibration, completely discharge the headphones and case before turning off. Then set them on charge and leave them for at least 3-4 hours, even if the indicator shows full charge earlier, this will allow the controller to re-read the real capacity of the cells.

If calibration didn't work, maybe the problem is the physical wear and tear of a lithium polymer battery, which has an average lifespan of 2-3 years of active use, and if your headphones are over three years old and discharge quickly, no software setup will restore their original autonomy.

💡

To extend the life of the battery, try not to keep the case with headphones permanently connected to the network after reaching 100% charge.
