The situation when the loved ones TWS-The headphones suddenly stop responding to commands, always catches you by surprise. You open the case, but the indicators don't light up, and the smartphone doesn't see the device on the list of available devices for connection. Panic at this point is not worth it, because in 90% of cases the problem lies in the banal nuances of battery operation or software failure, which is easy to fix.
In this article, we will take a closer look at all the possible causes of a device’s failure and provide a step-by-step algorithm for restoring functionality. Diagnosis begins with the simplest steps that are often overlooked, and ends with more complex manipulations of hardware and software.
Before you carry your gadget to a service center or require warranty repairs, try to perform a series of checks yourself, which will save you time and nerves, and help you understand the real nature of the malfunction.
Primary diagnosis: checking the charging case
The most common reason Xiaomi earbuds don't turn on is because they don't have a charge at all. Many users forget that the autonomy of the plugs themselves depends on the capacity of the case. If the case is discharged, it can't physically transfer power to the headphone contacts, even if they're lying inside for a long time.
Check the indicator on the charging case. When you connect a USB-C or Micro-USB cable, the LED should light up, signaling the start of the charging process. If the indicator is silent, try replacing the cable or power supply. Often the problem lies in a damaged wire that does not transmit enough current.
Also worth paying attention to the state of the charging contacts. Over time, the metal pens inside the case and on the legs of the headphones can accumulate oxide film, dust or earwax, which creates high resistance, which prevents charging.
⚠️ Note: Do not use metal objects (needles, pins) to clean the contacts inside the case, so as not to close the chain or damage the spring mechanism.
Clean the contacts with soft cloth without pile. Make sure the headphones fit tightly to the magnets and are properly positioned in the sockets. If the magnets hold weakly, there may be mechanical damage to the case case case case case case case case case.
Complete Reset (Hard Reset) procedure
If the charge is fine but the device is still dead, there may have been a software failure on the Bluetooth controller's firmware, in which case a forced factory reset helps, which deletes all temporary files and resets the error logs.
To perform a reset on most models, such as Mi True Wireless Earbuds or Redmi Buds, you need to place the headphones in the case and leave the lid open. Find the functional button on the case case (usually located on the end or between the compartments).
- 🔘 Press and hold the reset button during 10-15 seconds.
- 🔘 Watch for the LED light: it should start flashing red or change the pattern of blinking.
- 🔘 Release the button only after the indicator goes out or lights up in white/green, signaling success.
Then remove the old pairing in your smartphone's Bluetooth settings. Find the device in the list, click "Forget the device" or "Unpair the pairing." Only then re-initiate the search and connection.
☑️ Algorithm of resetting headphones
For some versions that do not have a physical button, the reset is performed by simultaneously touching the touch zones on both headphones for 5-10 seconds while they are in the ears or in the case.
Contact group problems and oxidation
Even if the headphones appear to be charging, a microscopic layer of dirt can block the current transmission, moisture, sweat and cosmetics gradually destroy the contact coating, which is especially true for models without high-level moisture protection.
Carefully inspect the golden or silvery areas. If you notice black plaque or darkening of the metal, you need careful cleaning. Use a cotton swab dipped in isopropyl alcohol. Movement should be light, without strong pressure.
If the problem persists after cleaning, try bending the contacts inside the case up slightly (literally by a millimeter) to ensure a tighter press, but this should be done with extreme care so as not to break the plastic base.
| Symptoms. | Possible cause | Method of decision |
|---|---|---|
| Case indicator doesn't burn. | Failed cable or charging port | Replace the cable, clean the port |
| Headphones flash but don't turn on | Critically low battery charge | Leave in the case for 30-60 minutes |
| Only one headphone works. | channel-synchronization | Execute Hard Reset of both devices |
| Quiet sound or wheezing | Sound grid contamination | Clean carefully with a brush |
Regular preventive cleaning of contacts once a month will prolong the life of your device and prevent situations when the headphones stop turning on due to a banal lack of power.
Deep battery discharge
Lithium polymer batteries used in TWS-In the case of a device that has been unused for several months, the voltage in the batteries may have dropped below a critical threshold, in which case the power controller blocks charging for safety reasons.
To rock this battery, you need to leave the headphones in the connected case for a long time - from 2 to 4 hours. Do not try to turn them on in the first 30 minutes, even if the indicator lights up.
