Which Xiaomi models support wireless charging?
Not all Xiaomi headphones can be charged wirelessly — this feature is only available in premium and some mid-budget models. Here is the current list for 2026:
- 🎧 Xiaomi Buds 4 Pro – support for Qi-standard (10 W), charging from any wireless device.
- 🎧 Xiaomi Buds 3T Pro – wireless charging (5 W), compatibility with charging pads Xiaomi and third-party brands.
- 🎧 Redmi Buds 4 Pro – limited support (only with Xiaomi’s 7.5W branded charging).
- 🎧 Xiaomi Air 2S — wireless charging (up to 2 watts), slower wired.
Note that even if your model supports wireless charging, the speed will be lower than when connected via cable. For example, Buds 4 Pro charge in 1 hour over the wire and 1.5-2 hours wirelessly. Also, some models (for example, Redmi Buds 3 Lite) require a firmware update to activate the feature - check this in the Mi Home or Xiaomi Wear app.
If you're not sure if your model supports wireless charging, look at the box or the specs on the official website, usually marked with a Qi icon or a Wireless Charging label.
Charging methods: wired vs. wireless
There are two main ways to recharge Xiaomi headphones — cable and wireless. Let's take a look at the pros and cons of each.
| Parameter | Wire-based charging | Wireless charging |
|---|---|---|
| Speed. | ⚡ Fast (1-1.5 hours) | 🐢 Slower (1.5-3 hours) |
| Convenience | ❌ We need to plug in the cable. | ✅ Just put it on the playground. |
| Compatibility | 🔌 Anybody. USB-C cable | 🔄 Only Qi-platforms (5-10 W) |
| Battery wear and tear | 🔋 Medium. | 🔋 A little higher because of the heat. |
Wireless charging is the most reliable and fastest way.
- Connect the cable. USB-C (Micro-USB for older models.
- Insert the other end in the power adapter (recommended) 5V/1A or the original block from Xiaomi).
- The indicator on the case should light up red (charging) or white (full charge).
Wireless charging is convenient, but has nuances:
- 🔄 Use only certified Qi sites (cheap ones can damage your battery).
- 📍 Position the case correctly - the center should coincide with the center of the site.
- ❄️ Remove the case from charging immediately after 100% to avoid overheating.
💡
If the Xiaomi Buds 4 Pro headphones don’t charge wirelessly, try updating the firmware through the Xiaomi Wear app. Up to 1.4.3 versions had a compatibility error with some Qi platforms.
Step-by-step: how to charge Xiaomi headphones for the first time
The first charge is a critical step that affects battery life. Follow this instruction to avoid errors:
Wait for the full discharge of the case (the indicator flashes red)
Use the original cable and adapter
Charge to 100% without interruptions (at least 2 hours)
Do not use headphones during the first charge.
After 100%, give "rest" 10-15 minutes before use-->
1. Discharge the case completely. If the headphones are new, wait for the indicator on the case to flash red (usually 5-10% charge), which calibrates the battery controller.
2. Connect the original cable. Use the complete cable. USB-C (Micro-USB for older models and power adapter 5V/1A. Cheap cables may not provide stable voltage, which will shorten battery life.
3. Charge without interruption. The first 3 charge cycles must be full (0% → 100%) without turning off. This forms the battery memory. Charging time for most models:
- 🎧 Redmi AirDots 3 - 1.5 hours
- 🎧 Xiaomi Buds 4 Pro – 1 hour (wireless), 1.5 hours (wireless)
- 🎧 Redmi Buds 4 Lite - 2 hours
4. Don't use headphones while charging. This puts additional stress on the battery and can cause overheating (ANC).
⚠️ Warning: If the headphones are discharged too quickly after the first charge (less than 3 hours of operation), the battery may not be calibrated. Repeat the discharge-charging cycle 1-2 times more.
How to check the charge level without a phone
Many users are unaware that the charge level of the case and headphones can be checked without connecting to a smartphone.
1.By the indicator on the case
- 🔴 Flashing red - less than 10% (urgent charging is needed).
- 🟡 Burning yellow/orange – 10–50%.
- 🟢 Burning green/white – 50–100%.
- 🔄 Flashing white – charging error (check cable or pad).
By sound signal (does not work on all models):
- 🔊 When opening the case: one signal – charge above 50%, two signals – below 50%.
- 🔊 When connected to the ears: the voice assistant reports the charge level (configured in the application).
3. Through a button combination (for advanced models):
- Press and hold the button on the case for 5 seconds - the indicator will flash a certain color (see the instructions for the model).
- For Xiaomi Buds 3 Pro: three times press the button on the case – voice assistant will voice the percentage of charge.
If the indicator behaves outside the box (e.g. flashing blue), this may indicate a faulty charging controller, in which case try to reset the headphones to factory settings through the Mi Home app.
