When your favorite gadget suddenly refuses to work, it always takes you by surprise. If your Xiaomi earphone stops turning on, it doesn't always mean a fatal failure. Most of the time, the problem is oxidation of contacts, software failure or deep battery discharge, which is easily fixed at home without going to the service center.
Modern wireless models, such as Redmi Buds or Mi True Wireless Earbuds, are complex microcomputers that may be triggered by a system lock or sensor malfunction, and require initial diagnosis of the device and the charging case before panicking.
In this article, we will take a closer look at all the possible reasons why Xiaomi earbuds don’t turn on, and provide a step-by-step algorithm for how to reset your settings, clear your contacts, and determine when self-repair is already powerless.
Diagnostics of charging case and contacts
The most common reason a wireless earphone doesn't turn on is because it doesn't have a charge, but it's not always because you forgot to put the case on the charger, and often the problem is that there's poor contact between the pins on the earphone itself and the contact areas inside the charger case.
Look carefully at the inside of the case, and at the bottom of the headphone indentations, there are spring-loaded contacts or magnetic pins, and over time, they can accumulate oxide plaque, dust, or earwax, which blocks the transmission of current, and a cotton swab, slightly dipped in isopropyl alcohol or dry alcohol, is ideal for cleaning.
⚠️ Warning: Never use water or wet wipes to clean contacts inside the case. Moisture entering the electronics can short circuit and permanently disable the device.
If the indicator on the case does not light up when connecting the cable, the problem may be in the charging cable or the power supply. Try using another USB-C or Micro-USB wire and an adapter with a current of at least 1 Amp.
Make sure the earpiece is properly fitted in the case, the magnets should be tightly attracted, and the LED indicator on the case (or on the earpiece itself, depending on the model) should light up, signaling the start of charging. If the indicator flashes red or does not light up at all, it is possible that the battery has gone into deep discharge.
The forced reset procedure (Hard Reset)
If the charging is fine but the headphone is still unresponsive, there may have been a software failure, in which case you need to perform Hard Reset, a procedure that returns the device to factory settings and often revives the "hung" gadgets.
For most Xiaomi and Redmi TWS models, the reset procedure is as follows: Place both headphones in the charge case and leave the lid open. Find the function button on the case (usually located between the headphone compartments or on the back).
Press and hold this button for 10-15 seconds. The indicator should start flashing white or orange, which signals a successful reset. If there is no physical button on the case, try pinching the touch zones on the headphones themselves while they are in the case, although this method works less often.
☑️ Algorithm of resetting headphones
Once reset, you need to pair your phone again. Go to your Bluetooth settings on your smartphone, find the old device in the list, and select "Forget the device" or "Delete." Only then turn on your headphones to search.

Battery problems and deep discharge
Lithium polymer batteries used in TWS-If the device was lying idle for several months, the voltage on the battery could fall below the critical threshold, and standard charging it does not "see".
To reanimate the battery, try the push charging method. Connect the case with headphones to a powerful power source (for example, from a computer or an adapter with 2A current) for a short time - 1-2 minutes, then turn it off and reconnect. Repeat the cycle several times. This can help raise the voltage to the level when the charging controller starts working normally.
| Status of the indicator | Probable cause | Action. |
|---|---|---|
| It's not burning. | Deep discharge or oxidation | Cleaning contacts, long-loading |
| Blinks red. | Critically low charge | Leave on charging for 1 hour |
| Flashing white/blue | Interconnection or failure | Perform reset (Reset) |
| It's burning all the time. | Charging completed or error | Check the earphone. |
It's important to understand that the battery life is limited, if the headphones are more than enough. 3-4 And in the years that followed, and they were long in the dead, the chemical degradation of the battery could be irreversible, and then it would be economically inefficient to replace the battery.
💡
Leave your headphones on charge at least once every 2-3 months, even if you don’t use them, which will prevent deep discharge and prolong battery life.
Mechanical damage and moisture intrusion
Xiaomi headphones are often used during training, which increases the risk of sweat or rain moisture getting inside the case. Even if the model has IPX4 protection, it only protects against splashes, but not from immersion or steam.
When moisture is placed on the board, it causes contacts to corrosion and short circuits. If the earphone falls into the water, it must be removed immediately, removed from the case (to avoid closing the contacts of the case), and put to dry in a dry place with good air circulation. Using a hair dryer or rice is not recommended, since rice dust can clog speakers and hot air damage the glue.
⚠️ Warning: Don't try to turn on a wet earphone or put it on charge! this is guaranteed to lead to electrolysis and final breakage of the board.
It can also be caused by mechanical impact, which could be a driver's plume or battery soldering that could be lost if you fall inside the body. TWS-The models often mean the destruction of.
If you notice cracks in the case or dynamic grid, the tightness is broken, and in the future, this earphone will be extremely vulnerable to dust and moisture, which will accelerate its failure.
Software conflicts and firmware updates
Sometimes the problem is not hardware, but software. Outdated headphone firmware can conflict with a new version of Android or iOS on your smartphone. Use the official Xiaomi Earbuds or Mi Home app to diagnose and update.
Connect your headphones to your phone and open the app. If your device is determined, check the firmware Update section. If a new version is available, install it by putting your headphones in your case and ensuring a stable Internet connection.
Path to Upgrade: Mi Home/Xiaomi Earbuds Application → Device Selection → Three Points (Menu) → Update CheckIn rare cases, the Bluetooth cache on the smartphone itself conflicts. Try clearing the Bluetooth cache in your phone settings: go to Settings → Apps → Show system → Bluetooth → Memory → Clear the cache. After that, restart the phone.
💡
Regularly updating the firmware of the headphones through the application fixes bugs and improves the stability of the connection.
When professional repairs are needed
If none of the above methods worked and the Xiaomi headphone still doesn't turn on, there's probably a hardware breakdown.It could be a power controller failure, a circuit break inside the battery, or a speaker damage.
Self-repair TWS-It's very difficult to have headphones, and they're adhesively assembled, and it's almost impossible to open without damaging the body, and replacing the battery requires soldering microscopic contacts and special equipment.
The cost of professional repairs is often 70-80% of the price of a new device, so if the warranty is already over, it is often more rational to buy a new model than to restore the old one.
