How much are Xiaomi Mi True Wireless Earphones wireless headphones charged: the full guide

Xiaomi Mi True Wireless Earphones Charging Time: Key Facts

Xiaomi Mi True Wireless Earphones (also known as Mi AirDots or Redmi AirDots depending on version) have become one of the most popular headphones. TWS-But many users are faced with the question: how long does it take to fully charge the case and the headphones themselves? The answer depends on the model, the type of charger and the current state of the battery.

In this article, we will discuss in detail:

• ⏱️ Standard charging time for different versions of headphones (Basic, Pro, S, 3, etc.)
• 🔋 How does the type of charger affect (5W, 10W, 18W) speed
• 📉 Factors that can slow down the process (battery wear, temperature, cables)
• ⚡ Practical tips for accelerating charging and extending battery life

It's important to understand that the charging time of the case and the charging time of the headphones inside the case are two different processes, for example, a case can charge from the network for 1.5-2 hours, and the headphones inside it for only 40-60 minutes.

Standard charging time for different models Xiaomi Mi True Wireless

The Mi True Wireless Earphones range includes several modifications, each with its own battery characteristics, and below is a table with current data for popular versions (2026):

Note: Charging time can be increased by 20–30% when using non-original cables or low power adapters (less than the previous one). 5W). For example, if you connect the case to USB-port of the laptop (usually) 2.5W), process will take up to 3 hours.

It’s also worth considering that new models (such as the Mi True Wireless Earphones 3 Pro) support fast charging — headphones can recover up to 1 hour of playback in 10 minutes in a case, but this requires an 18W adapter.

How the type of charger affects speed

One of the key factors that determines charging time is the power of the charger, and even if the case supports fast charging, it won't work without the right adapter, and we'll look at how different power sources affect the process.

• 🔌 Standard adapter 5W (from the kit: the best option for most models: charging the case will take 1.5-2 hours, headphones inside - up to 1 hour.
• ⚡ adapter 10W–18W: It speeds up the charge of the case by 20 to 30 percent (up to 1 to 1.5 hours), and for headphones, the difference is minimal, because their battery is small.
• 💻 USB-laptop (2.5W): The slowest solution. Case will charge 2.5-3 hours, headphones up to 1.5 hours.
• 🔋 Power Bank: Depends on the power of the port (10W+) charge the case in 1.5-2 hours.

Important: some users mistakenly believe that wireless charging (if supported by a model) works faster; in fact, it is usually 10-15% slower than wired charging due to energy loss. For example, a case of Mi True Wireless Earphones 3 will charge wirelessly in 2.5 hours instead of 2.

💡

If you often charge headphones from a laptop, use USB-A hub with additional power – this will speed up the process by 15-20%.

Also worth mentioning is backward compatibility: new case models (such as Mi True Wireless Earphones 3) can be charged with older 5W adapters, but time will increase, while older cases (such as Basic) will not benefit from powerful 18W adapters – their electronics do not support high speed.

Factors that slow down charging: what to check

If your Xiaomi Mi True Wireless Earphones are charging longer than the specified time, the problem may lie in one of the following factors:

• 🔋 Battery wear: After 300 to 500 charging cycles, battery capacity decreases by 20 to 30 percent, which increases charging time).
• 🌡️ Ambient temperature: at lower temperatures +10°C or higher +35°C lithium-ion batteries charge more slowly. Optimum range — +15…+25°C.
• 🔌 Cable or adapter: non-original cables with thin wires or damaged insulation reduce current.
• 📱 Background processes: if the case is connected to the smartphone via Bluetooth while charging, it can slightly slow down the process (5-10%).
• 🧲 Magnetic interference: Do not place the case near powerful magnets (such as speakers) – this can disrupt the charging controller.

Special attention should be paid to the contacts of the case and headphones, which can become oxidized or contaminated over time, leading to poor contact. Use a cotton swab dipped in alcohol (at least 70%) to clean.

⚠️ Warning: If the case heats up higher +40°C while charging, turn it off immediately. Overheating can cause the battery to bloat or even catch fire.

How to speed up charging: practical tips

If you need to charge Xiaomi Mi True Wireless Earphones quickly, use these recommendations:

Use the original 10W+ adapter

Turn off Bluetooth on your smartphone while charging

Charge at room temperature (+20...+25°C)

Clear the contacts of the case and headphones

Do not use the case during charging (do not open the cover)

-->

One of the most effective ways is to charge a part, for example, if you need 1-2 hours of battery life, just hold the headphones in a case for 10-15 minutes (assuming the case is charged), which will save time and reduce battery wear.

It is also worth paying attention to charging modes:

• 🔄 Cyclical charging: If you frequently charge your headphones 10-20% instead of discharged to 0%, the battery will last longer.
• 🛑 Avoid full discharge: Lithium-ion batteries degrade faster if they are regularly discharged to 0%.
• ⚡ Use smart sockets: some models (for example, Xiaomi Mi Smart Socket) allow you to turn off power on the timer, preventing overcharging.

For models that support wireless charging (such as Mi True Wireless Earphones 3), you can use Xiaomi’s wireless charging stations to provide stable current and overheat protection. However, as mentioned earlier, the speed will be lower than with wired charging.

💡

The fastest way to charge headphones is to use the original 10W+ adapter and charge the case separately from the headphones (first the case to 100%, then insert the headphones).

Frequent User Mistakes and How to Avoid Them

Many Xiaomi Mi True Wireless Earphones owners make mistakes that shorten battery life or increase charging time.

⚠️ Note: Never use adapters with more power to charge a case 20W (This can damage the power controller, as most models require no more than that. 10W.

• 🔌 Using cheap cables: thin wires or no shielding causes voltage to drop.Buy certified cables USB-IF.
• 🌞 Charging in the sun or in the car: High temperatures accelerate battery degradation. avoid direct sunlight.
• 📵 Storage of discharged headphones: if you do not use headphones for more than a month, charge them up to 50% before storing them.
• 🔋 Using the case as a power bank: some people plug the case into a smartphone to charge it, which is extremely inefficient and harmful to the battery of the case.

Another common problem is the display problem, for example, the case shows 100% charge, but after 10 minutes of use, the headphones are discharged.

• Failure of the battery controller (solved by resetting settings through the Mi Home application).
• Battery wear (replacement required).
• Bad contact between the case and headphones (clean contacts).

If the charging indicator flashes red or does not burn at all, try resetting the case: press the button on the case for 10-15 seconds before resetting.

Comparison with competitors: who is charging faster?

For objectivity, compare the charging time of Xiaomi Mi True Wireless Earphones with popular analogues from other brands:

As you can see from the table, Xiaomi is not far behind the competition in charging speed, and in some cases (for example, Mi True Wireless Earphones 3) even ahead of them in terms of price and functionality.

It’s important to note that Xiaomi often optimizes its devices to work with proprietary adapters.For example, the case of Mi True Wireless Earphones 3 charges 15% faster with a Xiaomi adapter. 18W Fast Charge, rather than universal 10W-adapter from another brand.
