How to charge headphones Xiaomi AirDots 2: full instruction with tips

Headphones Xiaomi AirDots 2 (aka Mi True Wireless Earphones 2 Basic) have become one of the most popular TWS-But even these simple gadgets have questions about how to use them, especially when it comes to charging. How to charge a case? How long does it take to fully charge the headphones? Why does one earphone discharge faster than another? These and other nuances we'll go through in detail.

Unlike wired headphones, wireless headphones require attention to two components: the headphones themselves and the charging case. Incorrect charging can lead to shorter battery life, unstable operation or even breakdown. In this article, you will find not only basic instructions, but also practical tips for extending the life of the battery, as well as solving typical problems.

Package and connectors: what goes into the box and how to connect

Before you charge, it’s important to make sure you have everything you need. The standard Xiaomi AirDots 2 comes with:

• 🎧 Two wireless headphones (left and right)
• 🔋 Charging case with built-in battery
• 🔌 Cable USB Type-C (in some versions, Micro-USB)
• 📄 Short instructions (often in several languages, including Russian)
• 🔄 Additional Ambusheries (depending on the region of supply)

And you can look at the type of case charger, and most of the time, this is the case. USB Type-C, but in early batches or regional versions, Micro-USB may have been encountered. If your cable does not fit, do not try to connect headphones through an adapter: this can damage the power controller.

Also check the charge indicator on the case. AirDots 2 has it in the front and can burn white (charging is going), red (low charge) or green (fully charged). If the indicator does not glow at all, the problem may be in the cable, port or case itself.

Step-by-step instructions: how to charge the case and headphones

The charging process is two-step: first, the case itself is charged, then the headphones inside the case, and let's look at both.

Charging a case from a network or power bank

To charge the case, perform the following actions:

1. Connect. USB-The cable to the case. The connector is on the back.
2. The other end of the cable is inserted into the charger (power supply from a smartphone, laptop or power bank).
3. The indicator on the case should light up red (if the battery is discharged) or white (if charging has begun).
4. Wait until the indicator turns green, which signals a 100% charge.

The full charge time of the case is about 1.5–2 hours, but may vary depending on the power of the charger. 5V/1A (standard USB-Laptop port) the process will take longer than the power supply 5V/2A.

Charging the case headphones

AirDots 2 headphones charge automatically when they are inside the case.

1. Place both earbuds in the nests of the case, and they should be securely fixed with magnets.
2. Close the case cover. The case indicator will flash white once if the headphones start charging.
3. After 10-15 seconds, the indicators on the headphones themselves will go out – this is normal.
4. Full charging of headphones takes about 1 hour.

The important thing is, if the case is discharged, the headphones won't charge, even if they're inside. First, charge the case to at least 20 to 30 percent, then put the headphones in it.

💡

If one of the headphones is not charging, try to clean the contacts (nests in the case and metal dots on the headphones) with a cotton swab dipped in alcohol, often the problem lies in oxidation or contamination.

How much charge AirDots 2: real tests and official data

According to the manufacturer, Xiaomi AirDots 2 provides:

• 🎵 Up to 4 hours of continuous music playback on a single headphone charge.
• 🔋 Up to 12 hours when using the case as a power bank (3 full cycles of charging headphones).
• ⏳ Time of full charge of the case: 1.5-2 hours.
• ⏳ Charging time of headphones from the case: about 1 hour.

But the real tests show slightly different numbers, like 70 to 80 percent loudness and heavy microphone use, and the time is reduced to 3 to 3.5 hours, and if you listen to music at maximum volume, the headphones can run out in 2.5 to 3 hours.

Critical feature of AirDots 2: if one earphone is completely discharged and the second is still working, the case may not recognize the discharged earphone when you put it back, in which case only a complete recharge of both earphones will help.

Typical Charging Problems and Their Solutions

Even when used properly, users face challenges. Let's look at the most common ones.

Case's not charging.

If the indicator does not light up when connecting the cable:

• 🔌 Check the cable and charger - try charging another gadget.
• 🧹 Clean the charging port on the case of dust and debris (use a toothpick or compressed air).
• 🔄 Try another one. USB-port (for example, on the back of the PC instead of the front panel).
• 🔋 If the case does not respond at all, the battery may have failed - repairs will be required.

Headphones don't charge in the case

Causes and solutions:

• 🧲 Check if the case cover is tightly closed – if not, charging will not start.
• 🔗 Clear contacts on headphones and in case nests (see tip above).
• 🔄 Reboot the headphones: Place them in the case, close the lid for 10 seconds, then pull out and insert again.
• 🔋 Make sure the case is charged (the indicator should be green or white when connected to the network).

One earphone is charging, the other is not.

This is one of the most common problems.

1. Change the headphones to the places in the case - the nest may be faulty.
2. Check whether the indicator on the problem headphone is lit when placed in the case.
3. If the indicator is not on, try to reset the headphones (see section below).
4. If nothing helps, contact the service - a malfunction of the power controller is possible.

⚠️ Warning: If your headphones don't connect to your phone after reset, try connecting your right earphone (the headphone) first, and then your left.

How to prolong the life of the battery: tips for operation

Batteries in TWS-Headphones wear out over time, but a few simple rules will help keep their capacity longer.

Optimal charge level

Try to avoid two extremes:

• 🔋 Deep discharge (when headphones or case discharge to 0%) – this reduces battery life.
• ⚡ Constant charging up to 100% – if the case is always connected to the network, the battery degrades faster.

The ideal range is 20 to 80 percent, and of course, with headphones, it's hard to control, but at least don't let them run out for long.

Temperature regime

The lithium polymer batteries used in AirDots 2 are temperature sensitive:

• ❄️ Avoid charging at a temperature below +5°C.
• 🔥 Do not leave headphones or case under direct sunlight (for example, on a car torpedo).
• 🚗 Optimal operating temperature: from +10°C +35°C.

Headphone storage

If you don’t plan to use AirDots 2 for a long time (for example, a few months):

1. Charge the case and headphones to 40-50%.
2. Store in a dry place at room temperature.
3. Once every 1-2 months, take out the headphones, turn them on for 10-15 minutes and put them back in the case.

⚠️ Attention: if you leave the headphones discharged for six months or more, their battery may completely fail and not recover even after charging.

💡

Regular use and maintenance of charge at the level of 30-70% is the key to a long battery life in the world. TWS-headphones.

Alternative charging methods: what to do if there is no original cable

So there are different situations, like a cable is lost, a connector is broken, or a charger is not on hand, and we'll look at all the options.

Use of non-original cable

If you have a cable with a suitable connector (Type-C or Micro-USB), but not from Xiaomi:

• 🔌 You can use a cable from another device, but it must support data transfer (not all charging cables are suitable).
• ⚡ The power of the charger must be 5V/1A or 5V/2A. Voltage power supplies 9V, 12V and above may damage the controller.
• 🛡️ Avoid cheap no-name cables – they can cause short circuits.

Charging from a power bank or laptop

If there is no socket, the case can be charged:

• 🔋 From Power Bank (External Battery) with Exit 5V/1A or 5V/2A.
• 💻 From USB-port of the laptop (usually issued) 5V/0.5A, charging will be slower).
• 📱 From the smartphone charger (if it supports Quick Charge, the case will still charge in standard mode).

Wireless charging

Xiaomi AirDots 2 does not support wireless charging according to the Qi standard. If you see cases with this feature on sale, it is either a fake or a modified version (which does not guarantee stable operation).

The only safe way to do this is to use wired charging, and if the connector on the case is damaged, it's better to take it to a service center to replace the port than to experiment with alternative methods.

How to check the level of charge of headphones and case

Unlike smartphones, TWS-The headphones don't show the exact percentage of charge, but there are a few ways to estimate the remaining capacity.

Case indicators

On the front panel of the case there is an LED that signals status:

• 🔴 Red - charge less than 20%.
• 🟢 Green – charge over 80% (or full charge).
• ⚪ White -- charging is going on.
• 🔄 Flashes white - headphones charge inside the case.

Notifications on a smartphone

On devices running Android 8.0+ iOS 13+ When connecting AirDots 2, a charge level notification may appear:

• On Android: Open the notification panel → Find the headphone icon → press it.
• On iPhone: Open Settings → Bluetooth → Find AirDots 2 in the list of devices (the percentage of charge may be displayed next to it).

If there are no notifications, try installing the official Mi Home app (although it doesn’t always correctly display charge for that model).

Sound signals

AirDots 2 headphones provide voice notifications in Chinese (in some firmware, in English).

• 🔋 "Di di (short double signal) – headphone charge is high.
• 🔴 "Di" (one long signal) - charge critically low (less than 10%).
• 🛑 No sound when pressing the button – headphones are discharged.

💡

To headphones reported the level of charge in Russian, you can reflash them using applications like TWS Toolbox, but it’s risky and can lead to loss of functionality.
