Owners of the popular Xiaomi Mi True often wonder about the speed of energy recovery, especially when the gadget is discharged at the most inopportune moment. The time required for a full cycle directly affects the comfort of use and planning of the day of the modern user. On average, it takes 40 to 90 minutes to fully charge the headphones themselves, but this figure varies depending on the specific model and the capacity of the case.
The rate of charge recharge depends on many technical factors, including the condition of the lithium polymer battery and the power of the power supply unit used.
Understanding these processes helps avoid common mistakes that can lead to battery degradation after a year of active use.
In this article, we will discuss in detail the time intervals for different versions, the impact of the environment and the real indicators obtained during the testing.
Average charging time for different models
The Mi True Wireless Earbuds range spans multiple generations of devices, each with unique power consumption characteristics.
Basic models such as the Mi True Wireless Earbuds Basic typically take about 1.5 hours to fully recover the capacity of the liners themselves, while more advanced versions with active noise cancellation can charge longer due to complex electronics.
It is important to consider that case charging often has its own timeline, which can be anywhere from 2 to 3 hours when using a standard cable.
- ⏱️ Basic 1 series models and 2S: 1 hour 30 minutes for headphones, 2.5 hours for case.
- ⏱️ Pro-labeled versions: 60 to 90 minutes thanks to accelerated charging support.
- ⏱️ Flagship models with ANC: up to 2 hours at full discharge due to large battery capacity.
- ⏱️ Wireless charging of the case: increases the total time by 20-30% cable-wise.
⚠️ Note: Using cheap cables without data transmission support can significantly increase charging time or lead to unstable performance of indicators.
The time difference is due not only to capacity, but also to power management algorithms built into Bluetooth chip controllers.

Factors affecting the rate of energy recovery
The rate of charge recharge is affected by a variety of external and internal parameters, which are often ignored by users.
The ambient temperature plays a critical role: at low temperatures, the chemical reactions within the lithium-ion element slow down, which increases the charging time.
In addition, the condition USB-port on the charger and the quality of the cable itself can create resistance that reduces current strength.
If you charge headphones from a computer port, the process may take longer than a 1A or 2A network adapter.
Also, it is worth considering the residual capacity: the last 10-15% of the charge is always collected more slowly due to the operation of the balancing system of the cells.
This is necessary to prevent overheating and ensure maximum battery life.
Why do headphones warm up when charging?
A little heating (up to 40 degrees) is the norm for lithium batteries during an active chemical process. However, if the case becomes hot enough to be unpleasant to hold in your hand, this may indicate a faulty controller or the use of an unoriginal cable with the wrong resistance.> How to properly charge the case and headphones.To ensure the durability of the device, it is important to observe the correct sequence of actions when connecting to the network. First, it is recommended to place the headphones in the case and make sure that they are fixed by magnets, as indicated by a flashing indicator. ☑️ Correct charging algorithmPut headphones in the case before clickPlug cable to the casePlug USB Check the lighting of the indicator Completed: 0 / 4 Some users prefer to charge the case separately from the headphones, which is also permissible but less convenient for status control.The indicator on the front usually burns red during the process and changes color to white or blue when it reaches the end of the day. 100%. It is important not to remove the headphones from the case when there is an active charging process, so as not to disrupt the calibration cycles of the controller. Charging time Characteristics Table For ease of comparison of different modifications of the Xiaomi and Redmi headsets, we have compiled a composite table with averaged data. Note that the actual numbers may vary slightly depending on the wear and tear of the battery. Time to charge headphones Case Charging Type Mi True Wireless Basic connector ~90 mine ~150 Micro-USB Mi True Wireless 2 Basic ~60 mine ~120 Type-C Air mine 2 Pro ~60 mine ~120 Type-C Redmi Buds mine 3 Pro ~50 mine ~90 As you can see from the table, switching to the Type-C connector in new models has reduced latency by almost half, especially for users who value their time and can not afford to wait long. Understanding the LED light signals helps the user know exactly where the process is going. In most Xiaomi models, red represents the active charge phase, and white or green represents the completion. If the indicator flashes red even after a long connection, it may indicate a deep discharge or contact error. 🔴 Burning red: active charging is underway (0-95%). 🟢 Burning white/green: charge complete (100%). 🔴 Flashing: connection error, deep discharge or malfunction. ⚪ Not burning: cable is not connected or the case is discharged. ⚠️ Warning: If the indicator does not light up immediately after the cable is connected, try cleaning the contacts in the port with compressed air or a dry soft brush. In some cases, when the battery is completely dead, the indicator can only light up through the use of a dry soft brush. 5-10 It's normal for lithium polymer batteries to be in a deep discharge state, and charging problems and solutions are often encountered when the headphones stop charging or are extremely slow. One of the most common reasons is the oxidation of contacts on the headphones themselves or inside the case due to moisture or sweat. Regular cleaning of contact areas with an alcohol napkin helps to avoid problems with current transmission, and the problem can be hidden in a software failure, which is solved by resetting the headphones to the factory settings. 10-15 If software methods don't work, you might need to replace the battery that's exhausted. 💡90% Charging problems are solved by simply cleaning contacts or replacing them. USB-Tips for extending the life of the battery To ensure that your Mi True lasts as long as possible, you must adhere to certain rules of operation. 100%, Although modern controllers cut off current, micro-charge cycles still wear out the battery. It is also necessary to avoid storing the device in a completely discharged state, as this leads to irreversible chemical changes. 40-60%. If you plan to not use your headphones for several months, charge them half and turn them off (if there is such an option) or simply leave them in the case off. Avoid extreme temperatures: do not leave the gadget in the sun in the car or in the cold. ⚠️ Warning: High-power charging (e.g. from Quick Charge units) 3.0/4.0 for smartphones) is not always safe for small headphone batteries unless they have a controller. 1And-2A. Compliance with these simple rules will keep the battery capacity at a high level during the period of time. 2-3 years of active use. Remember, the battery life is limited to the number of cycles, and careful attitude is the only way to extend it. Frequently Asked Questions (FAQ) Why does the case charge longer than the headphones themselves? The case contains a battery of much larger capacity, since its task is to recharge the headphones in the field. In addition, the current charging the case is often limited by the port design and internal protection circuit. Can you use headphones while charging the case? No, in most Xiaomi Mi True models, it is impossible to use headphones while they are inside the charging case. You will have to remove them in the field, then the controller safely switch them on the night. However, to maximize battery life, it is best to remove them from charging immediately after the process is complete. What if one headphone is charging faster than the other? A small difference is acceptable, but if it is significant, try to clean the contacts of the slower-charged headphone. If this does not help, there may be wear and tear of one of the batteries or a malfunction of the contact group in the case.
