When Xiaomi’s favorite Redmi Buds or Mi True Wireless suddenly stop responding to commands, it always takes you by surprise: You take them out of your pocket, open your case, but no indicator lights up, and no connection to your phone is available. This is a common problem faced by owners of both the Chinese giant’s budget and flagship wireless acoustics models. Often, panic causes users to immediately look for a service center, although in most cases the device can be reanimated on their own in minutes.
The reasons for this behavior of the gadget can range from the banal deep discharge of the lithium-ion battery to software failures of the microcontroller. TWS-Headphones are complex computerized devices that need the right trigger algorithm. Before you write them off, you need to eliminate simple operational errors and try soft resuscitation methods.
In this article, we will look at all possible scenarios for failure of the equipment, we will look at mechanical malfunctions, problems with charging contacts and software freezes. Competent diagnostics will help you save time and money by bringing the device back to life without the intervention of specialists.
Primary diagnostics and visual examination
The first step is always to have a thorough external inspection. Often the problem is in little things that are not visible when you look at them. Carefully examine the case and the headphones themselves for chips, cracks, or traces of moisture. If the device has recently fallen or come into contact with water, the likelihood of mechanical damage to the internal components increases many times.
Pay special attention to contact areas, which often accumulate earwax, dust and oxides that block the transmission of current. Dry cleaning with a cotton swab can instantly solve the problem if the headphones simply did not receive a charge due to poor contact. Also check the integrity of the charging cable and power supply, trying to charge another device from them.
Sometimes users confuse the lack of reaction with a discharged state: if the headphones were lying idle for a long time, their battery could go into a deep discharge, in this state, the indicators may not light up immediately after connecting to the network, you need to leave the case with headphones on charge for at least 30-60 minutes, even if there are no signs of life.
Make sure you use a proper power source. USB-Computer ports or original fast-charging units may not be safe for small electronics. USB 1A or special adapter for low-power devices.
💡
Use a soft dry cloth or cotton swab lightly moistened with isopropyl alcohol to clean the contacts. Avoid getting liquid inside the case.
Problems with charging and battery
The most common reason Xiaomi earphones don't turn on is because of the power supply system. Lithium-ion batteries are sensitive to storage and operating conditions. If the device has been left out for a long time, the voltage on the battery may have dropped below the threshold needed to activate the charge controller, in which case the standard indication may not work.
You need to check if the current is coming in, plug in the charging cable, and look at the LED light on the charger case, and if it's not burning or flashing in a strange way, the problem could be in the case or the cable, and try replacing the cord and the power supply with something that's obviously good.
If the case is charging but the headphones inside are not responding, there may be a disruption in the contact between the pins in the case and the contacts on the headphones. Try to gently move the headphones in the sockets or wipe the contacts. Sometimes it helps to temporarily remove the headphones and re-set with little effort (no fanaticism) to improve the connection.
In rare cases, the battery degrades, and if the device is several years old and has been in active use, the battery capacity may have dropped to a critical minimum, in which case the headphones can show charge, but immediately turn off when you try to play the sound or turn on.
- 🔋 Leave the case with headphones on charging on 2-3 Hours to "spin" a deeply discharged battery.
- 🧹 Carefully wipe the contact areas on headphones and inside the case with a dry cotton swab.
- 🔌 Try using another one. USB-cable and power adapter with less current (5V 1A).
- 🌡️ Check the temperature of the device: cold battery may not charge, warm it in your hands.
Hard Reset (Hard Reset) Methods
If the charging is fine but the headphones are still off, there's probably a software glitch. The device's microcontroller may have been stuck in an error cycle. In these cases, a forced reboot, similar to the battery extraction in older phones, helps. The algorithm may differ for different Xiaomi and Redmi models.
The most common method for TWS-You need to put the headphones in the case, open the lid, and pinch the touch zones on both headphones simultaneously, and hold them for a long time, from 10 to 30 seconds, until the indicators flash a certain color (usually red or white).
For some models, such as the Mi True Wireless Earbuds Basic 2, the reset is done by quickly pressing the touch panels five times. Others require pressing the button on the case itself (if any) for 10-15 seconds, and it is important to do this while the headphones are in the case or connected to the charger.
After a successful reboot, the headphones must go into pairing mode. On the phone, you need to remove the old device from the Bluetooth list and search again. If after reset, the headphones turn on, but there is no sound or only one one, the procedure is worth repeating.

Table of indication codes and their meaning
Understanding light signals is key to quick diagnosis: different colors and flashing modes tell the user about the specific state of the device. Below is a transcript of the most common signals for Xiaomi products.
| Indication | Colour | Regime. | Meaning |
|---|---|---|---|
| Case indicator | Red. | Permanent. | Charging a case or headphones. |
| Case indicator | Green. | Permanent. | Charging complete (100%) |
| Headphone indicator | Red. | Slow blinking | Low battery charge level |
| Headphone indicator | White/Blue | Fast blinking. | The mode of pairing (Pairing Mode) |
| Headphone indicator | Red. | 3 short flashes | Connection error or discharge |
If you see behavior that isn't described in the manual, it could indicate a hardware malfunction, for example, if the indicator burns red indefinitely and doesn't go green, it could be that the battery is malfunctioning or bloated, and in such cases, further operation can be dangerous.
Program conflicts and Bluetooth settings
Sometimes the problem isn't with the headphones themselves, but with the smartphone or tablet they're connecting to. Bluetooth cached data, profile conflicts, or outdated software can block the proper functioning of the accessories. Before you carry the headphones for repair, it's worth checking the phone's settings.
Try connecting to another device, and if you have a different phone or laptop, the headphones are on and working, it's a problem with the settings of the main gadget, and then cleaning the list of associated devices and resetting the network settings on the smartphone will help.
Also worth checking is the Mi Home app or Xiaomi Earbuds. Sometimes you need to update the firmware of the headphones themselves, which can only be done through the official app. If the headphones don't turn on at all, this method won't work, but if they flash, but don't connect, this is a solution.

When professional repairs are needed
Unfortunately, not all problems are solved at home. If none of the above methods worked, there was probably serious damage to the components. Battery bloating is one of the most dangerous problems. If you notice that the headphones or case has deformed, or there is a foreign smell, immediately stop trying to charge.
Moisture is another critical factor, and even if the headphones are labeled with waterproofing, they're designed for sweat and splashing, but not for immersion or steam. Contact corrosion may not occur immediately, but after an incident, requiring professional cleaning in an ultrasonic bath and replacement of the elements.
Also, the plumes, speakers or boards are to be repaired in mechanical shocks. TWS-The monolithic structure of the body and the use of glue make it extremely difficult to open the body without special means, and in 90% of cases, it causes permanent damage to the plastic and loss of leakage.
If the device is under warranty, it is better not to experiment with disassembly and immediately contact an authorized service center.
💡
If the headphones were exposed to water or have a bloated body, self-repair is dangerous - contact the service.
Prevention and proper storage
To avoid future problems with turning on, you need to follow the rules of operation of lithium batteries. Do not allow a full discharge to zero on a regular basis. If you plan not to use headphones for a long time, charge them up to 50-60% and store them for storage.
Temperature is also important: Do not leave the case with headphones in the sun, on the dashboard of the car in winter or summer. Extreme temperatures destroy the chemical structure of the battery, which leads to loss of capacity and inability to turn on.
Regularly clean the case of dust and pile, which can clog charging contacts. Use protective cases (silicone or leather), which cushion the impacts when falling, but do not interfere with ventilation. Careful attitude will prolong the life of your Xiaomi gadgets.
