Modern wireless headphones have become an integral part of the digital lifestyle, and the Xiaomi Mi True Wireless Earbuds Basic 2 is one of the most popular budget solutions on the market. However, like any portable device, they require regular power supply maintenance for stable operation. Many users face difficulties when charging for the first time or do not understand the signals that the charging case gives with its indicators.
In this article, we will take a look at all aspects of power consumption and recharge for this model, and you will learn not only about the basic rules of connection to the grid, but also about the nuances that will help to extend the life of a lithium polymer battery. Proper operation from the first days of use is the guarantee that the gadget will last you for many years without losing capacity.
It is worth noting that the charging process here has its own characteristics, different from charging smartphones or other accessories Xiaomi. improper contact handling or use of poor-quality cables can lead to irreversible consequences.
Package and necessary accessories
Before you start charging, you need to make sure that you have all the necessary components. The standard Mi True Wireless Earbuds Basic 2 headphone box includes the case itself, two headphones, a Micro-USB charging cable and a set of interchangeable earpieces. The absence of any of these elements, except for the earpieces, can be a problem.
Special attention should be paid to the cable. The kit usually comes with a short cable about the length of the cable. 10-15 centimeters, which is designed exclusively for charging the device from USB-It's not a data port or adapter, and it has a specific connector design.
- 🔌 Micro-USB cable (included in the package)
- 🔋 Power adapter 5V/1A (often missing from the kit, used from a smartphone)
- 📦 Charging case with built-in battery
- 🎧 Headphones with individual batteries
If the original cable is lost, you can use any other quality cable with a Micro-USB connector that supports a current of at least 1 Amp. Using cheap analogues can lead to overheating and slow charging, which will negatively affect the chemistry of the battery.
⚠️ Warning: Do not try to charge the headphones directly by inserting the cable into the headphones themselves. The charging socket is located only on the case case case body, not on individual modules.
Step-by-step instructions for charging the case
The process of replenishing the energy in the charging case is the primary step, since it is the case that charges the headphones themselves. First, connect the smaller end of the Micro-USB cable to the corresponding port located on the lower or lateral face of the case. It is important to be careful not to damage the internal contacts of the connector.
Second end of the cable (USB Type-A needs to be connected to a power source. USB-A port of a computer, laptop, car charger or network adapter, and when connected, a red indicator will light up on the front of the case, signaling the beginning of the process.
☑️ Pre-charging check
The full charge time of the case from zero to 100% is about 1.5-2 hours. When the battery is fully full, the red LED will go out or change color, depending on the version of the power controller firmware, and then the device is ready to go and can charge the headphones several times.
If the indicator on the case flashes red when placing the headphones inside, this means a low charge of the case itself, and it must be urgently connected to the network.
How to charge the headphones inside the case
The most common mistake for beginners is waiting for a separate charge for each headphone. Xiaomi Mi True Wireless Earbuds Basic 2 has an automatic charge on contact. Once you put the headphones inside the case and close the lid, the power transfer process begins.
To successfully charge, you need to ensure that the metal areas on the headphones are in close contact with the response pins inside the case. If the headphones are installed incorrectly or dust has accumulated in the connectors, charging may not begin.
- 👂 Place the headphones in the case's nests
- 🔒 Close the cover tightly until a characteristic click.
- 💡 Check that the case indicator has caught fire (usually red when charging)
- ⏳ Leave the device for 1.5 hours for a full cycle
The full charge time of the headphones inside the case is about 1.5 hours, at which time it is not recommended to open the lid often, so as not to interrupt the calibration cycle of the controller. Once the process is complete, the indicator on the case will go out, signaling the readiness of the gadget to listen to music.
Why is the indicator flashing?
Indication and status of LEDs
Understanding color is key to controlling the device. The Mi True Wireless Earbuds Basic 2 uses a simple but informative LED light on the front of the case, and the color and burn mode inform the user of the current state of the system.
When the case is charged, the light is a straight red light, which means that the current is fed into the battery of the case, and if the case is fully charged, the light may go out or, in some revisions, turn white for a short time.
| Status of the device | Color of indicator | Rey's work. | User action |
|---|---|---|---|
| Charging the case | Red. | Permanent. | Waiting for completion |
| Case loaded. | Missing/White | Pogasus/Gorite | You can turn it off. |
| Charging headphones | Red. | Permanent. | Wait 1.5 hours |
| Contact error | White | Migayette | Check the installation |
| Pairing. | White | Frequent flashing | Search in Bluetooth. |
And I'm going to mention the pairing mode, which is that if you take the headphones out of the case and they flash white quickly, it means they're ready to connect to the smartphone, and in this mode, the battery consumption is high, so don't keep them in search mode too long unnecessarily.
💡
To keep the battery in charge when stored, keep the headphones in a case with the lid closed, which means they go into deep sleep and use almost no energy.
Autonomous life and charging speed
One of the main characteristics that users are interested in is the duration of work on a single charge. For the Xiaomi Mi True Wireless Earbuds Basic 2 model, the claimed time for listening to music is up to 4-5 hours at medium volume, which is a standard indicator for devices in this price segment.
The charge case is capable of fully charging the headphones about 2-3 times, so the total battery life, taking into account the recharges from the case, can reach 12-15 hours, this is enough for active use throughout the day, including travel and training.
Charging speeds are not record high, as they use a standard charging protocol without Quick Charge fast charging technology, but current stability ensures safety and prevents overheating, which is more important for compact devices with a dense layout.
⚠️ Warning: Do not leave your headphones in a case on charge for more than 24 hours after full charge. Although the controllers must cut off the current, prolonged exposure to voltage can accelerate the degradation of lithium cells.
Typical problems and methods of their solution
Even when properly operated, users can experience situations where the headphones stop charging, most often the problem is oxidation of the contacts, metal pins on the headphones and inside the case eventually become covered with a layer of oxide or contaminated with earwax.
To solve this problem, take a dry cotton swab or soft cloth slightly moistened with alcohol and gently wipe the contacts. After cleaning, let them dry for 5 minutes and put the headphones back in the case. In most cases, this restores normal charging.
Another common problem is the battery's "sleep mode" if the device has been lying unused for a long time. If the indicator does not light up immediately after connecting to the network, leave the case with headphones on charging for 30-60 minutes. Sometimes it takes time to "rock" the deeply discharged battery.
Operational rules for extension of service life
To make your Mi True Wireless Earbuds Basic 2 last as long as possible, you should stick to a few simple rules: Lithium polymer batteries do not like extreme temperatures. Do not leave the case in direct sunlight, on the dashboard of the car in summer or in the cold in winter.
Also, try not to discharge the device to zero regularly. The optimal range for lithium batteries is from 20% to 80%. If you plan not to use headphones for a long time, charge the case to about 60% and turn off the device (if you have such an option) or just leave it closed.
- 🌡️ Avoid temperatures higher +45°C and below 0°C
- 💧 Keep the device from moisture and sweat
- 🧹 Clean your contacts regularly from contamination
- 🔌 Use only good cables and adapters
Compliance with these recommendations will keep the battery capacity at a high level even after a year of active use. Remember that replacing the battery in such compact devices is often not economically feasible, so taking care from the start is the best investment.
💡
Regularly cleaning contacts and avoiding deep discharge are two of the main factors determining the longevity of your Xiaomi headphones.
