Wireless speakers often face a situation where the case stops charging the headphones and the device discharges at the most inopportune moment.The problem can be both oxidation of contacts and software failure of the power controller. In this article, we will discuss all the nuances of the energy recovery process for the popular models of Xiaomi Airdots and Mi True Wireless Earbuds.
Modern. TWS-Xiaomi headsets require certain conditions to be met for the power system to work properly. If you notice that the indicators do not light up or the process is too slow, do not panic. In most cases, the fault can be eliminated independently without contacting the service center, if you follow the algorithm of actions accurately.
The key is to understand how the charging cycle works in your device. Different models of Xiaomi Airdots may differ in the display and logic of the controller, we will look at the universal methods that will suit most generations of these headphones, and also point out specific features.
Device of the power system and types of indication
To effectively manage the charge, you need to understand how the display system in the case works. Depending on the specific modification of the Xiaomi Airdots, the color scheme may differ. Usually, the LED on the front panel reports the status of the battery inside the box.
When you plug in the cable, the light turns red, signaling the start of the energy storage process. After the cycle is complete, the color changes to white or the indicator goes out, depending on the version of the controller's firmware. It's important not to confuse the case indication with the headphone indicators, which can flash when installed in the sockets.
⚠️ Note: If the indicator on the case flashes red immediately after the cable is connected, this may indicate a critically low charge level or malfunction of the lithium polymer element.
Some models, such as the Airdots Pro or Airdots 2, use a more complex system of three LEDs or more. OLED-Here, each light can correspond to about 33% of the charge, and the blink indicates a standby mode or an error in connecting with the headphones inside.
Exact value of indicators
Step-by-step instruction for case charging
The power recovery process in the Xiaomi Airdots box looks standard, but requires attention to connection details.First make sure you use a serviceable cable with the appropriate connector, usually a Micro-USB or Type-C.
Connect the cable to the port on the lower or lateral side of the case, and insert the other end into the power adapter. It is recommended to use a current source with a current of no more than 1A or 1.5A, so as not to damage the charge controller.
☑️ Connection check
If you use powerful fast-charging smartphones (Quick Charge, Power Delivery), the process may go wrong. handshake protocols may not align, and the case simply won't start taking power.
- 🔌 Use the standard. USB-computer port or simple 5 volt adapter.
- 🔋 Leave the device to charge for 1.5-2 hours before the white indicator lights up.
- 🚫 Avoid using damaged or too long cables that cause a voltage drop.
💡
Optimally charge the case from USB-port of the laptop or old adapter on 5V/1A – This extends the battery life.
What to do if the case does not charge the headphones
When the case is charged, but the headphones themselves do not receive energy, it is quite common. The first and most common cause is contamination of the contact areas. The golden patches eventually oxidize metal or accumulate earwax, preventing current from passing.
To fix the problem, gently wipe the contacts on the headphones and inside the case with a dry cotton swab. You can slightly moisten the wand in isopropyl alcohol, but be sure to let the moisture completely evaporate before installing the headset back.
It's also worth checking if the headphones are sitting tightly in their niches. Sometimes the magnets weaken and the device doesn't fully sink into the socket, which keeps the electrical circuit from closing. Try pressing the headphones with your fingers for a few seconds after installation.
⚠️ Note: Do not use metal objects (needles, paper clips) to clean contacts, as you can damage the protective coating or close the chain.
If mechanical cleaning didn’t help, it may be a software failure of the Xiaomi Airdots controller, which requires a forced reset procedure that often restores the normal logic of the power system.
Resetting and reconnection procedure
If you're not charging, try a full headphone reset, which returns factory settings and often eliminates battery status errors, and take the headphones from the case and make sure they're off.
On most Airdots and Airdots 2 models, you need to pinch the touch areas on both headphones simultaneously and hold for about 20 seconds. The indicators should blink several times, after which the device will go into pairing mode.
For models with a physical button on the case, such as the Airdots Pro, the algorithm is different: you need to place the headphones in the case, open the lid and hold the button on the case for about 15 seconds until the color of the indicator changes.
- 🔄 Remove old Bluetooth pairing in phone settings.
- 📱 Reset the headphones according to the instructions for your model.
- 🔗 Re-search and connect the device.
Compatibility and charging time table
Different generations TWS-Xiaomi headsets have different battery capacity and, accordingly, different full recovery times. Below are tentative data for popular models that will help you plan the use of the device.
| Model | Case capacity | Charging time. | Type of connector |
|---|---|---|---|
| Xiaomi Airdots | 300mAh | ~1.5 hours | Micro-USB |
| Airdots 2 | 300mAh | ~1.5 hours | Micro-USB |
| Airdots Pro | 470mAh | ~2.0 hours | Type-C |
| Airdots 3 | 420mAh | ~2.0 hours | Type-C |
It should be noted that these values are relevant when using a serviceable cable and a standard adapter. USB-Hubs) time can increase by one and a half to two times.
Diagnostics of battery failures
If the case charges very quickly (in 10-15 minutes) and discharges just as quickly, this is a sure sign of battery degradation.
Another symptom of a malfunction is the case heating during charging. Normal operating temperature is a slightly warm state. If the case gets hot, immediately disconnect the device from the mains to avoid battery bloating.
⚠️ Warning: A ballooning battery can damage the case case case and disable the electronics of the headphones.
In case of signs of bloating or unstable operation, the only safe solution is to replace the battery in the service center or self-replace with the appropriate skills and tools.
💡
The battery life of the case is on average 2-3 years of active use, after which the capacity is inevitably reduced.
