The situation when the loved ones TWS-The headphones suddenly stop showing signs of life, they always take you by surprise, and you take them out of the case, but the indicators are silent, and the smartphone can't see the device. In a panic, many users immediately look for a service center or plan to buy a new model, forgetting that in 80% of cases the problem is solved by a banal reset or cleaning contacts. Xiaomi gadgets, whether itβs budget Redmi Buds or flagship Mi True Wireless, are equipped with reliable electronics, but software failures or oxidation of connectors can temporarily disable them.
Before you despair, you need to make a thorough diagnosis to understand the nature of the malfunction. Most often, the βdeadβ state is caused by a deep battery discharge or a microcontroller hanging inside the case. The right sequence of actions will help bring devices back to life without financial costs and complex soldering. In this article, we will discuss all possible scenarios for restoring the health of your wireless headphones.
It's important to understand that resuscitation is a process that requires patience and attention to detail. Wrong actions can make things worse, so follow the instructions consistently. We'll look at methods from the simplest reboot to the more complex manipulation of contacts and software.
Diagnostics and initial inspection of the device
The first step in the recovery process is to visually inspect and check the physical condition of the accessories. Carefully examine the case and the headphones themselves for external damage, cracks, or traces of moisture. Even a microscopic drop of sweat or rain can cause the contacts to short-circuit or oxidize, which blocks charging. Make sure the LED lights on the case do not flash strange colors, which could indicate a critical battery error.
Then you need to check the charger and the cable. Use only serviceable USB Type-C or Micro-USB cables, and stable current adapters. Often the problem is not with the headphones themselves, but with the power supply that gives off insufficient voltage. Try connecting the case to the computer port or other adapter to prevent a malfunction of the power source.
β οΈ Warning: If you notice a bloating case or strong heating when connecting to a charge, immediately disconnect the device from the network.Operation of a damaged lithium polymer battery can lead to a fire.
Pay special attention to contact areas, which often accumulate earwax, dust and pile from pockets, creating an insulating layer. Use a cotton swab slightly soaked in isopropyl alcohol to clean. Gently wipe the golden contacts on the headphones and pins inside the case, removing all visible plaque.
Hard Reset (Hard Reset) Methods
If the look is perfect, but the devices are not working, there's probably a software failure, in which case the method is to perform a hardware reset, which is a process that returns factory settings and clears the microcontroller's memory of errors. For most Xiaomi models, such as the AirDots or Redmi Buds 3, the algorithm is standard, but there may be nuances.
Place both earbuds in the case and leave the lid open. Find a function button on the case body (usually round and located on the end or inside between compartments). Press and hold it for 15-30 seconds. The indicator should start flashing red and white or quickly light up in orange, which signals the start of the reset process.
- π Hold the button until the indicator blinks three times in a row.
- π If there is no button on the case, try touching the sensors on both headphones at the same time. 5-10 The second they are in the ears.
- π± After reset, remove the old pairing in the phone's Bluetooth menu before reconnecting.
In some models, such as the Mi True Wireless Earphones 2, you can reset through touch control. Place the headphones in the case, close the lid, then open it and press the sensors of both earphones simultaneously for 5 seconds. The indicators should light up, confirming the successful execution of the command. If standard methods do not help, try to βdischargeβ the case completely, leaving it open for a few days, and then charge it to 100%.
Problems with charging and battery
Lack of response to charging is one of the most common reasons users are looking for ways to reanimate headphones. If the indicator on the case does not light up when the cable is connected, the problem may be deep battery discharge. Lithium batteries tend to lose capacity during prolonged downtime, and the charging controller can block the current for safety reasons.
To rock the battery, try using the pulse charging method. Connect the case to the power source for 1-2 minutes, then turn it off for a minute. Repeat this cycle 5-10 times. Sometimes this allows you to raise the battery voltage to a level where the regular charging system will start working correctly again. You can also try charging the case from the computer's USB port, since the current is less there, and the controller may perceive this as a safe signal.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The indicator is not on. | Deep discharge or chain break | Pulse charging method |
| Blinks red. | Low charge or contact error | Cleaning contacts and long-term charging |
| Burning white all the time | Headphones not in the case or crash | Reconnect the power cable |
| Only one charger. | Pollution of the pin of one of the headphones | Thorough cleaning with alcohol |
If the case is charging, but the headphones inside are not gaining power, check the density of the fit. Sometimes the spring contacts inside the case will fail. Carefully, using a thin dielectric tool (for example, a toothpick), try to raise the spring-loaded pin a little bit so that it better contacts the earpiece. Don't put too much effort into not breaking the mechanism.
π‘
Use magnets to check the operation of the case: if the headphones are not magnetized tightly, it is possible that metal shavings or dirt have accumulated in the holes of the case.
Working with the application and reconnecting
Modern Xiaomi headphones are closely integrated with the ecosystem through the Xiaomi Earbuds or Mi Wear app. Sometimes a software conflict in the smartphone operating system interferes with the correct operation of accessories. In this case, you need to completely clean the connection profiles. Go to the Bluetooth settings, find your headphones in the list of associated devices and select βForget the deviceβ or βUnpairβ.
Once you delete the device, reboot your smartphone, which will clear the Bluetooth cache and reset the temporary driver errors, then open the headphone management app and try to find them again. If the app doesnβt see the device, make sure that geolocation is enabled, as itβs a must-see requirement for Android search. BLE-device.
β οΈ Warning: Do not try to connect the headphones to the phone while they are in the process of reset (flashing the indicator.
In the app, check for firmware updates. Manufacturers often release patches that fix battery discharge or connection stability issues. If the update freezes, interrupt the process, put the headphones in the case, close the lid, and try to re-start the update in 10 minutes.
Specificity of recovery of different models
Xiaomi's various headphone lines have their own design and control features. For example, the first-generation Redmi AirDots often featured left- and right-channel desynchronization. Resuscitation requires resetting each headphone individually, removing the second from the case. Newer models, such as the Mi True Wireless Earphones 2 Pro, use low-latency technology, and failures are more often associated with codecs.
The Gaming Edition games have a low latency mode that can conflict with some smartphones. If the headphones are working but the sound is interrupted or missing in one channel, try turning off the low latency mode in the app. In active noise cancellation (ANC) models, the failure can cause a buzz or whistle, in which case switching the noise reduction modes several times in a row helps.
- π§ Redmi Buds 3 Lite: Reset is done by triple touching the sensor when in the case.
- π§ Mi Air 2: Requires a long-term hold on the case button (about 20 seconds).
- π§ Haylou (sub-brand): Often require clearing Bluetooth history on your phone before re-matching.
If you have a specific model that is not on the list, look for the exact button combination instructions for your article. There is no one-size-fits-all method for all devices, although the electronics work the same way. In difficult cases, it helps to search the exact code of the model on the back of the case.
Secret Diagnostic Regime
When professional repairs are needed
Despite all efforts, there are situations where software methods and cleaning do not help: if the case battery is swollen, the smell of burning from the device or the transformer hums, further operation is dangerous, and the sign of hardware failure is the lack of response to charging after a day of connection to a good power source and performing all the discharge procedures.
Inside headphones, lithium batteries can fail, which eventually lose their ability to hold charge. Replacing them requires the skills of soldering small electronics and the availability of special equipment. It is extremely difficult to open the sealed headphone case of Xiaomi without damaging plastic latches and membranes.
If the device is under warranty, do not attempt to repair it yourself, as this will lead to loss of warranty obligations. Contact an authorized service center. For devices without warranty, repair may not be economically feasible if the cost of work exceeds 50% of the price of a new device.
βοΈ Checklist before going to the service
Prevention and proper care
To avoid the need for resuscitation in the future, it is important to follow the rules of operation: do not allow the battery to be completely discharged "to zero" for long periods. If you do not plan to use headphones for a long time, charge the case to 60-70% and leave it in a cool place, periodically (every 2-3 months) recharge.
Regular hygiene is key to long-term contacts. Wash your headphones with a dry wipe after every workout or use outside. Moisture and salts in sweat are the main enemies of electronics. Store your devices in a dry place, away from direct sunlight and heat sources.
