Xiaomi Mi True Wireless Earbuds Basic 2: How long do the headphones and case charge?

Wireless headphones Xiaomi Mi True Wireless Earbuds Basic 2 has become one of the most popular budget solutions for music lovers and active users. Their compactness, high-quality sound and long life on a single charge attract attention, but many buyers are worried about the question: how long it takes to fully charge the headphones and case?

In this article, we will examine the official data from the manufacturer, real user tests and nuances that affect charging speed. You will learn how to properly charge the Mi True Wireless Earbuds Basic 2 to extend the battery life, what mistakes owners often make, and what to do if the headphones charge too long or do not charge at all. We will also compare charging time with competitors and give practical tips for optimizing the process.

Official data: charging time from Xiaomi

According to the manufacturer’s specifications, Xiaomi Mi True Wireless Earbuds Basic 2 has the following charging characteristics:

• 🔋 Charging time of headphones in case: about 1.5-2 hours from 0% to 100% (using the original cable and adapter).
• 🔌 Case Charging Time: Approximately 2-2.5 hours through the port USB Type-C.
• 🔄 Number of full case charges: up to 3-4 times (case battery capacity – 300 mA·h, headphones – 43 mA·h each).

It is important to keep in mind that these figures are relevant for ideal conditions: ambient temperature. 20–25°C, original charger with output 5V/1A and no background processes (e.g., active Bluetooth connection while charging) in reality, the time may differ from the time of the charge. 10–20% big-side.

The manufacturer also points out that 10 minutes of charging in a case is enough for 1.5-2 hours of listening to music, which is useful if you urgently need to use headphones, but they are out of order.

Real tests: how much are charged headphones in practice

Independent reviews and user tests show that the actual charging time of the Mi True Wireless Earbuds Basic 2 can vary.

The table shows that the power of the charger significantly affects speed, for example, an adapter with a 5V/2A output can reduce the charging time of the case by 10-15 minutes, but this will slightly speed up the charging of the headphones themselves, since their controller limits the current.

It’s also worth noting that the last 20% charge (80 to 100%) often takes up almost half of the total time, which is due to a battery protection algorithm that slows down charging in the final stage to extend the battery life.

⚠️ Note: If your headphones charge for more than 3 hours using the original cable, this may indicate a faulty battery or charging controller.

What affects charging speed: 5 key factors

At the time of charging Xiaomi Mi True Wireless Earbuds Basic 2 is affected by several parameters.

1. Power of charger. Output adapters 5V/1A or 5V/2A It will provide optimum speed. USB-port of the computer or weak adapter (5V/0.5A) extend the charging time by 30–50%.
2. Ambient temperature: The ideal range is 15–30°C. At temperatures below 10°C or above 35°C, charging may slow down or stop altogether to protect the battery.
3. Battery state: After 300 to 500 charging cycles, the battery capacity decreases, and the charging time can increase, and this is also affected by the depth of discharge: if the headphones are discharged to 0%, the first charge will take longer.
4. Cable quality: Non-original or damaged cables can have increased resistance, which reduces charging current, especially for cheap cables with thin wires.
5. Background: If the headphones are connected to the device via Bluetooth while charging, some of the energy is used to maintain the connection, which slightly increases the time.

Fun fact: some users have noted that the first charge after purchase can take 20-30 minutes longer than the next charge, which is due to the calibration of the battery controller.

Do you use the original cable and adapter?

Check the temperature of the headphones (they should not be hot)

Clean the contacts of the case and headphones from dust and oxidation

Try another one. USB-port

Update the headphone firmware (if available)-->

How to speed up charging: practical tips

If you need to charge Mi True Wireless Earbuds Basic 2 fast, use these tips:

• ⚡ Use the exit adapter 5V/2A. It is safe for headphones and will reduce the time of charging the case on the headphones. 10–15 minute.
• ❄️ Charge in a cool place. Avoid direct sunlight or heat sources (such as near a laptop).
• 🔌 Turn off Bluetooth. If the headphones aren't used while charging, disconnect them from the device via Bluetooth settings.
• 🔄 Try to recharge your headphones at 20 to 30 percent charge, which will prolong battery life and speed up the process.
• 🧹 Clean the contacts. Periodically wipe the metal contacts on the headphones and in the case with a cotton swab dipped in alcohol to remove oxidation.

Note that fast charging (technology like Quick Charge or Power Delivery) is not supported by these headphones. Using adapters with voltages higher than 5V will not speed up charging, but can damage the controller.

💡

If you need to use headphones urgently, but they are discharged, charge them in a case for 10-15 minutes. This will last for 1-1.5 hours of work, even if the total charge of the headphones does not exceed 20%.

Comparison with competitors: who is charging faster?

For objectivity, compare Xiaomi Mi True Wireless Earbuds Basic 2 with popular counterparts in the same price segment:

As you can see from the table, Mi True Wireless Earbuds Basic 2 are not leaders in charging speed, but also do not lag behind the main competitors in the budget segment. Huawei FreeBuds 4i and Samsung Galaxy Buds Live charge faster, but also cost much more. It is important to consider that the battery capacity of the case Xiaomi is comparable to its counterparts, and battery life (up to 5 hours on a single charge) is at an average level.

If you are critical to charging speed, look for models that support fast charging (for example, Xiaomi Buds 3 Pro or Redmi Buds 4 Pro), but be prepared to pay 1.5-2 times more for this.

Frequent problems and their solutions
