The first charge is critical to battery durability. The manufacturer recommends completely discharge the headphones before first connecting to the network, however, this rule is only true for nickel-metal hydride batteries. Mi True Wireless Earbuds Basic 2 has lithium-polymer batteries that do not require "training".

1. Connect the case to the power source using the original cable USB Type-C.
2. Wait for full charging (the indicator on the case will stop flashing and will light up solid white).
3. Remove the headphones and use them until full discharge (until a low charge warning starts sounding).
4. Repeat the charging-discharge cycle 2-3 times to calibrate the power controller.

⚠️ Note: Do not use fast chargers with higher power for the first charge. 5V/1A. High current can damage the case power controller, which will lead to unstable operation in the future.

Ways to charge the case and headphones

The Mi True Wireless Earbuds Basic 2 supports two main ways to recharge energy: via cable. USB Type-C and wireless charging (in Qi-enabled models) and consider each in detail.

Charging via cable USB Type-C

It's the basic and most reliable way to charge.

1. Connect the cable. USB Type-C to the case (connector located on the back panel).
2. The other end of the cable is inserted into the power adapter or USB-laptop.
3. The indicator on the case will start flashing red (charging is going) or burning white (charging is completed).

The full time of the case is 1.5–2 One hour with an output adapter 5V/1A. If you connect the case to the port USB 3.0 computer, the time may increase to 3 chronological.

Wireless charging (for supported models)

Some versions of the Mi True Wireless Earbuds Basic 2 are equipped with a Qi module, which allows you to charge the case at wireless stations.

1. Place the case on the Qi charging pad (the center of the case should coincide with the center of the site).
2. Wait for the indication to appear (blinking orange light).
3. Charging will take 2-2.5 hours – longer than cable.

Important: Wireless charging is less efficient and generates more heat, which can negatively affect battery life when used regularly.

Charging Indicators: What Colors Mean

The Mi True Wireless Earbuds Basic 2 case is equipped with an LED indicator that signals the charging status.

If the indicator flashes white 3 times in a row, it indicates a malfunction.

• 🔌 Check the cable and connector for damage.
• 🔄 Try another power adapter.
• 🧹 Clean the case contacts of dust or dirt (use a dry cotton swab).
• 📱 Update the headphone firmware through the Mi Home app (if available).

⚠️ Warning: If the indicator does not light up at all, this may indicate a deep discharge of the case battery. In this case, leave the case on charging for 10-15 minutes - if the indicator does not appear, contact the service center.

Charging time and autonomy

The official specifications of Xiaomi Mi True Wireless Earbuds Basic 2 promise up to 4 hours of continuous music playback on a single charge of headphones and up to 12 hours, taking into account the recharging from the case.

• 🔊 Reproduction volume (at maximum volume, the operating time is reduced by 30-40%).
• 📶 Bluetooth connection quality (unstable signal increases power consumption).
• 🎵 Codec used (SBC less energy-consuming than AAC).
• 🌡️ Ambient temperature (at a temperature below 0)°The battery capacity is temporarily reduced).

Critical information: Full charge of the headphones inside the case takes 1.5 hours, and the case from the network – 2 hours. However, if you charge the headphones and the case at the same time (for example, connecting the case to the network with earphones placed inside), the total time can increase to 2.5-3 hours due to current restriction.

To optimize charging time:

• 🔋 First charge the case to 100%, then place the headphones in it.
• ⚡ Use the exit adapter 5V/2A Accelerated charging (but do not exceed this threshold!).
• 📵 Disconnect the headphones from the device while charging (this will reduce power consumption).

💡

If you often listen to music in the gym, charge your headphones at a temperature of 10–25°C. Overheating or hypothermia during charging reduces battery life by 20-30%.

Typical charging errors and how to avoid them

Many users make mistakes that lead to premature battery wear or unstable headphones, and consider the most common of them:

1. Use of non-original cables and adapters

Low quality cables may have improper contact brazing or insufficient wire cross section, resulting in:

• 🔥 Overheating of the connector USB Type-C.
• ⚡ Unstable charging current (case may be disconnected or fail to recognize connection).
• 📉 Rapid wear of the battery due to voltage surges.

Solution: Use only certified labeled cables USB-IF and adapters that support Quick Charge 3.0 or USB-PD.

Charging at extreme temperatures

Lithium polymer batteries are temperature sensitive.

• 🌡️ <0°C – leads to incomplete charge and risk of short circuit.
• 🔥 >40°C – accelerates battery degradation (capacity loss up to 50% in 6 months).

Solution: Charge your headphones indoors at room temperature. If the case overheats (for example, after being in direct sunlight), let it cool before connecting to the network.

3. Storage of discharged case

If the case is left empty for a long time (more than 2 weeks), the battery can enter a deep discharge state, after which recovery is impossible, the optimal charge level for storage is 40-60%.

⚠️ Warning: If you haven't used your headphones for more than a month, remove them from the case and store them separately.The built-in case controller continues to consume power even when it's off, which can result in a complete discharge.

How to extend the battery life

The average battery life of wireless headphones is 300 to 500 charge-discharge cycles, but if you use it properly, that number can be increased to 800.+ Here are the key recommendations:

1. Avoid full discharge and recharge

The optimal charge range for lithium polymer batteries is 20-80%.

• 🔋 Less than 5% (this increases internal battery resistance).
• ⚡ Charging above 95% (accelerates electrode oxidation).

Exception: 1 time in 2-3 months, it is recommended to conduct a full discharge-charging cycle for calibration of the controller.

2.Use smart sockets with a timer

If you charge your headphones at night, plug the adapter into a smart socket (like the Xiaomi Mi Smart Plug) and set up an automatic shutdown after 2 hours.

3. Update firmware

The manufacturer regularly releases updates that optimize energy consumption to check the relevance of the firmware:

1. Connect the headphones to the smartphone via Bluetooth.
2. Open the Mi Home app.
3. Go to the Devices section → Mi True Wireless Earbuds Basic 2 → Settings → Firmware update.

If an update is available, install it at a case charge level of at least 50%.

💡

Regularly charging in small portions (10-20%) is less harmful to the battery than the rare full cycles. Try to recharge your headphones every day, not once a week.

Troubleshooting during charging

If the Mi True Wireless Earbuds Basic 2 headphones or case are not charging, follow the diagnostic algorithm:

If the headphones are not recognized by the case when placed inside:

1. Make sure the headphones are properly installed (magnets must work with a characteristic click).
2. Check if the headphones are on fire when extracted from the case (if not, the contact problem).
3. Reset the headphones: Place them in the case, then press and hold the touchpads on both headphones for 15 seconds (until double beep).

If none of the methods worked, use the warranty (12 months from the date of purchase) or contact an authorized Xiaomi service center.
