Modern wireless headphones from Xiaomi have become an integral part of the lives of millions of users, offering high-quality sound and usability. TWS-The headset has been a stable work for many years, and it is necessary to approach the energy recovery process correctly. Many owners make mistakes that can shorten the battery life or lead to a break in the charging case.
In this article, we will take a look at all aspects of charging, from the choice of cable to the nuances of working with indicators, you will learn why lithium-ion batteries require special attention and how to avoid common problems with connection to the network.
Before we go into specific models, it's important to understand the basic principle of operation: charging takes place in two stages: first, energy goes to the case itself, and then it is transferred to the headphones when they are inside, and breaking this logical chain often raises questions for users who are faced with the fact that the indicators do not light up.
Main types of connectors and compatibility of cables
The first thing that a user encounters when buying is choosing the right cable. Most modern Redmi AirDots and Mi True Wireless models come with a Micro-USB port or a more modern Type-C. It is important to carefully inspect the bottom of the case so as not to damage the connector by trying to insert the cable on the wrong side.
Using the original cable is not just a whim of the manufacturer, but a necessity. Cheap analogues may not meet current standards, which will lead to overheating or extremely slow charging. If the original wire is lost, choose cables from proven brands with support for fast data transfer.
⚠️ Warning: Never use damaged cables with broken insulation. Power surges can disable the power controller inside the case, after which it will be impossible to restore the device.
For models with a Type-C port, it is permissible to use powerful power supplies from smartphones, since the controller independently regulates the current. However, with Micro-USB ports, it is better to reinsure yourself and use units with a capacity of no more than 1 Ampere to avoid overheating.
Step-by-step instructions: how to charge the case and headphones
The charging process looks simple, but it has its own technical nuances that are worth considering: first, you need to place both earphones inside the charging case before the characteristic click of the magnets, only after that you can connect the cable to the port on the case.
The process is usually indicated through LEDs. When you charge a case, the indicator is lit in red or orange, and after the battery is full, it changes color to white or green. If the indicators on the headphones inside the case do not burn, this is normal, they are activated only when removed.
☑️ Checklist for proper charging
Full charging time varies from 1 to 2 hours depending on the battery capacity of a particular model. It is not recommended to leave the device connected to the network for the whole night, although modern controllers are able to cut off current, you should not risk the battery life.

Indication and status of LEDs
Understanding LED signals helps to quickly diagnose the condition of the device. Unlike smartphones, there is no screen, and all information is transmitted through the blinking of light bulbs of different colors. Red almost always means the charging process or critically low charge level.
If the indicator flashes red and white alternately, this can signal a contact problem or an error (conjugation), in this situation, you should wipe the contacts with an alcohol wipe and try again.
💡
A green or white light indicates that charging is complete and the cable can be turned off.
Below is a table that deciphers the main signals for most AirDots and Earbuds models:
| Color of indicator | Mode of work | User action |
|---|---|---|
| Red is burning. | Charging is in progress (less than 50%) | Leave it connected. |
| White/green burning | Charge complete (100%) | Shut off the network. |
| Blinks red | Low case charge | I need you to charge. |
| Blinking white | Interconnection mode | Search for the device in Bluetooth |
Wireless charging for advanced models
Flagship models such as Xiaomi Buds 3 Pro or Mi True Wireless Earphones 2 Pro support Qi wireless charging technology.This allows you to replenish energy by simply putting the case on the charging pad of a smartphone or a powerbank.
To activate this mode, you need to center the case strictly in the center of the charger coil. Shifting even a few millimeters can interrupt contact, and the process will not begin.
The efficiency of wireless charging is lower than wired charging, so the energy replenishment time increases by about 20-30%, and the case can heat up more than usual, which is a normal physical process in inductive energy transfer.
💡
Use wireless charging to maintain your charge levels throughout the day, and at night or full discharge prefer cable for faster and more efficient operation.
Charging time and autonomy of operation
The average time of the headphones themselves from one charge is from 4 to 6 hours of active listening to music. The charge case is able to replenish the headphone battery 2-4 times depending on the model. Full charging of the case takes about 1.5 hours.
It is important to consider that when using the active noise reduction (ANC) function, battery life is reduced by 20-30%, and this should be remembered when planning long trips without access to the outlet.
If you notice that the headphones discharge faster than the manufacturer's stated time, try resetting the Bluetooth settings on the phone and perform a re-entry of the device. Sometimes software failures lead to incorrect display of the percentage of charge.
Frequent problems and methods of their solution
One of the most common problems is when the case is charging and the headphones inside are not, most often it is oxidation or contamination of the contact areas, and regular cleaning with a dry cotton swab or stick with minimal alcohol solves this problem.
⚠️ Warning: Do not use metal objects to clean the contacts.This may short-circuit or mechanical damage to the gilded areas.
Another problem is that the battery is dead after a long period of downtime, and if the headphones have been empty for months, they can go into a deep discharge, so leave them on charge for 30-60 minutes, even if the indicator doesn't respond immediately.
If neither method works, the battery inside the case or the headphones themselves may have failed, and this requires a call to a service center to diagnose and replace the battery.

Tips for extending battery life
To yours. TWS-headphones lasted as long as possible, try not to allow a full discharge to zero. Lithium-polymer batteries feel best at the level of charge from the battery. 20% before 80%. Regular cycles 0-100% Faster use of the chemical composition of the battery.
Store the device at room temperature. Extreme cold or heat (such as leaving the car in the summer) can irreversibly damage the battery, reducing its capacity forever. Avoid moisture, as most models do not have full moisture protection.
💡
Regular use of headphones (at least once a month) prevents battery degradation during long-term storage.
Compliance with these simple rules of operation will allow you to enjoy the quality sound of your device throughout its life, remember that the right charging is the foundation of a long life of any portable electronics.
