When one of Xiaomi’s or Redmi’s wireless headphones stops working and doesn’t turn on, it’s familiar to many users. Often it’s not because of a breakdown, but because the device has gone into a deep sleep or lost pairing with the main module. Finding such a “lost” component inside or outside the case is a task that requires understanding the logic of Bluetooth protocols and the specifics of charging docks.
Unlike active devices that can be tracked by GPS, a switched off or discharged earphone does not transmit signals. The main problem is oxidation of the contacts or software freeze of the power controller, you will have to conduct diagnostics to exclude mechanical damage and software errors.
In this guide, we will analyze the algorithms of actions for different models. TWS-We're going to look at hardware reset techniques, display features, and how to force sleep mode to be activated, and following the instructions carefully will help bring the device back to life in most cases.
Diagnosis of the state of the charging case
The first step is always to check the power supply, and if the case is discharged, it will not wake the headphones, even if their own batteries are charged, and the indicators on the dock case often flash red or do not light up at all, which can be misleading.
You need to check the integrity of the charging cable and the absence of contamination on the contacts inside the socket. Contact oxidation is a common reason why current does not flow to the headphone battery. Use a dry cotton swab to clean the metal areas carefully.
⚠️ Warning: Do not use wet wipes or alcohol to clean contacts unless you are sure that the case is completely tight.
Try leaving the case with the earbuds attached on charge for at least 30 to 60 minutes. Sometimes Li-Ion batteries go into deep discharge, and it takes time for them to start a chemical reaction. If the case indicator catches fire, then the power chain is restored.
Forced inclusion and discharge methods
If external charging doesn’t work, you should use a Hard Reset procedure, which eliminates software errors from a controller that may have blocked the device from turning on. The algorithm may differ from Xiaomi to Redmi.
Most often, you need to remove both headphones from the case and pinch the touch areas for 10-20 seconds. In some models, such as AirDots, you need to press the buttons on the headphones themselves while they are not in the case. In other cases, such as in Mi True Wireless Earbuds Basic 2, you need to press the button on the case with the covers open.
☑️ Algorithm of resetting headphones
A successful reset is usually accompanied by flashing the indicators in white or red, and then the device goes into pairing mode, and it is important to perform these actions quickly and consistently, since the timer for entering the setting mode is often limited to 5 seconds.
What if the reset didn't help?
Search for lost headphones through the Mi Home app
For modern models of the Xiaomi ecosystem, there is the ability to track location through the Mi Home or Xiaomi Earbuds app. However, this feature only works if the headphone is on and has a battery charge. If the device is turned off completely, digital search is impossible.
However, it's worth checking the connection history of a smartphone, and if the headphone is even briefly turned on and transmitted a signal, the map may show the last known dot, which is true for models that support the Find My Device protocol.
The app also has a headphone search feature that makes the device emit a loud beep, which is useful if you lost the earphone in the room, but it is still active. For a device that is turned off, this method, alas, will not work, but it is definitely worth checking the charging status through the application.
💡
Turn on the case discharge notification in the Mi Home app. This will let you know in advance when the charger will empty, and the headphones will not be left without power in the bag.
Compatibility table and indicators
Different headsets have different logics for how the indicators work, and understanding color coding helps diagnose the problem faster, and here is a summary of the popular series.
| Model | Case indicator (Discharged) | Indicator in case (charge) | Resetting action |
|---|---|---|---|
| Redmi AirDots | Red flashing | Red is burning. | Clip the buttons for 5 seconds. |
| Mi True 2 Basic | Orange | White flashing. | Case button 10 seconds. |
| Xiaomi Buds 3 | Red. | Green/White | Double-click on the case |
| Haylou GT1 | Red. | Blue/Red | Triple sensor press |
Note that in some models, the indicator inside the case only lights up when the lid is opened. If you close the lid, the LED can go out after 10 seconds to save energy, which does not mean that charging is stopped.
Contact group problems and mechanical malfunctions
Often the reason that the earphone does not turn on is the banal lack of contact between the charging pins of the case and the earpiece. Over time, oxide film forms on metal sites or earwax accumulates, which is a dielectric.
Mechanical cleaning should be done carefully, you can use a toothbrush with a minimum amount of isopropyl alcohol, but only if you are confident in your skills, after cleaning, you need to thoroughly dry the device.
⚠️ Warning: If you notice that one of the contact pins in the case is "dropped" or springs weaker than the other, do not press the headphone force.
It's also worth checking if the earphone fits tightly into the socket. In some budget models, the plastic case may have a backlash, which causes contact to disappear, in which case it helps to neatly lining a small piece of foam or paper under the headphone in a tight fit case.
💡
90% of problems with “non-inclusion” are solved by high-quality cleaning of contacts and long (more than an hour) charging with the original cable.
When a service center is needed
There are situations where self-repair is not possible. If after all the cleaning, reset and long-term charging procedures, the indicators are silent, the battery or charge controller is likely to fail. Lithium polymer batteries have a limited cycle life and can degrade in 2-3 years.
In addition, moisture entering the housing (even in models with IPX4) can cause corrosion of the board, visually it can manifest as a green plaque on the contacts, the restoration of such devices requires soldering and replacement of elements, which is only possible for specialists.
If the device is under warranty, do not attempt to open the case yourself. Breaking the seals is guaranteed to result in the denial of free repair.
