Why it is important to correctly determine the charging of Xiaomi headphones
Xiaomi headphones are among the most popular wireless gadgets on the market due to the ratio of price to quality. However, many users face the problem: how to tell if the device is fully charged? Undercharging or overcharging the battery can significantly reduce battery life, and the wrong interpretation of indicators often leads to premature replacement of headphones.
In this article, we’ll look at all the different ways to check charging for different models, from the budget Redmi Buds to the premium Xiaomi FlipBuds Pro. You’ll learn how to read light signals, use a mobile app, and why headphones sometimes lie about the level of charge. And also a unique life hack for models with a hidden charging indicator, which is not written in the official instructions.
Method 1: Indicator on the case case case case - decoding colors and blinks
The most obvious way is to look at the LED light on the front of the charging case, but not everyone knows that Xiaomi has three types of display, depending on the model and year of release. Let's take a look at them in detail.
Most headphones (e.g. Redmi AirDots 2/3, Mi True Wireless Earbuds 2) use a single-color white/red indicator:
- 🔴 Red constant - charging is going, the battery level of the case is below 20%.
- 🟡 Yellow/orange constant (less often) – charging is going, level from 20% to 80%.
- 🟢 Green constant – charging completed (100%).
- 🔴 Red flashing – critically low case charge (less than 5%).
Newer models (Xiaomi Buds 4 Pro, FlipBuds Pro) have a multicolor RGB indicator and can display intermediate states:
- 🟠 Orange flashing – charging headphones inside the case (if the case is connected to the network).
- 🔵 Blue constant – the case is 100% charged, but the headphones are still charged.
- 🟣 Purple flashing – charging error (check contacts or cable).
⚠️ Note: If the indicator does not burn at all when connected to charging, the problem may be in the cable, port USB Try another cable and power supply before you go to the service.
Method 2: Sound signals – what do squeaks mean when charging
Many Xiaomi models emit audible signals when connected to a charge or reaching 100%, which is especially convenient if the case is in the bag or you can not see the indicator.
| Model headphones | Connection sound | Sound at 100% charge | Additional signals |
|---|---|---|---|
| Redmi AirDots (1-3) | Short double squeak | Long single signal | Three short squeaks - charging error |
| Xiaomi Mi True Wireless 2 | 3-note melody | Rising melody (4 notes) | Intermittent squeak - headphones are not in the case |
| FlipBuds Pro | Voice Charging (in Chinese/English) | Voice "Charging is complete" | — |
| Buds 4 Pro | The sound of the USB connection | Double high signal | Low horn - overheating of the case |
If there is no sound at all, check:
- 🔊 Volume level on headphones (sometimes signals are muted in the settings).
- 🔌 Quality of contacts between headphones and case – try reinstalling them.
- 📱 On some models, the sounds are turned off via the Mi Home app.
💡
If Xiaomi headphones do not emit sounds when charging, but the indicator is on, try resetting them to factory settings: press the button on the case for 10 seconds before flashing red and white.
Method 3: Mi Home App – Exact percentage of charge
The most reliable way to use the official Mi Home app (or Xiaomi Wear for new models) is to show the exact percentage of charge of both the case and each earphone separately.
Connect your headphones to your phone via Bluetooth|Open the Mi Home app → Devices|Choose your headphones from the list|Check the section "Battery status»-->
The annex shows:
- 📊 Case charge level (in percentage and graphically).
- 🎧 Charge of left and right earphone separately.
- ⚡ Charging status ("Charging" or "Charging completed»).
- ⏱️ Remaining charging time (for some models).
If the application does not show data:
- Update your Mi Home to the latest version.
- Reconnect the headphones to your phone (Bluetooth Settings → Forget the device).
- Check if your model supports this feature (e.g. Redmi AirDots 1 does not display percentages).
⚠️ Note: Some firmware Mi Home can show a case charge of 100%, when in fact it is charged by 90-95.
Method 4: Charging time – how much to wait up to 100%
If the indicators and sounds don’t work, you can focus on charging times, which depend on the model and type of charging. Here are the averages for popular Xiaomi headphones:
| Model | Case Charging Time (0→100%) | Time to charge headphones in the case | Type of charging |
|---|---|---|---|
| Redmi AirDots 2 | 1.5 hours to 2 hours | 1 hour | Micro-USB, 5W |
| Mi True Wireless 2 | 1 hour | 40 minutes. | USB-C, 10W |
| FlipBuds Pro | 1.5 hours | 30 minutes. | USB-C, 18W (Fast Charging) |
| Buds 4 Pro | 45 minutes. | 20 minutes. | USB-C, 20W + wireless charging |
It is important to consider:
- ⏳ If the case is completely discharged (<5%), first 10–15 The indicator may not burn for a minute, it is normal.
- ⚡ When using fast charging (from the 10W) The case is heating up - it's not a defect.
- 🔋 Headphones are charged in the case only when the case is connected to the network or has a sufficient charge (>10%).
What to do if the headphones are charged for too long?
Method 5: Hidden Functions – How to Check Charge Without an Indicator
Some Xiaomi models (such as the Redmi Buds 3 Lite) have a hidden charge indicator that is not described in the official instructions.
- Connect the case to the charger.
- Open the case lid.
- Press and hold the button on the case for 3 seconds.
- The indicator will flash red/green the number of times corresponding to the level of charge: 🔴 1 flashing - 0-25% 🟡 2 blinkings - 25-50% 🟢 3 blinks - 50-75% 🟢🟢 4 flashes - 75-100%
This method works for most budget models where there is no RGB-You can also use a voice assistant:
- Put the headphones on the phone.
- Activate the voice assistant (Google Assistant or Siri).
- Ask, “What is the charge level of the headphones?” (works for models with Fast Pair support).
💡
If your Xiaomi headphones don’t show charge in standard ways, try a combination of buttons or voice assistant – this often works even on older models.
Frequent Mistakes and How to Avoid Them
Many users misinterpret the headphone signals, which leads to premature battery wear. TOP-5 Mistakes and how to avoid them:
- Turn off charging with a green light — on some models, the green color appears at 90% charge. Wait for a constant green light (without blinking).
- Use of non-original cables – cheap cables may not provide the right current, which causes the case to only charge up to 80%. Use a cable from the kit or a certified USB-C/USB-A.
- Charging from a computer or power bank — USB-PC ports often give out less current (0.5A instead 1A–2A). Use a network adapter to fully charge.
- Storage of discharged headphones – if you leave the headphones in a discharged case for a month, the battery can fail. Charge the case to at least 30% before long storage.
- Ignoring overheating – if the case is hot to the touch, disconnect it from charging for 15-20 minutes. Overheating reduces battery life by 20-30%.
Also, you should remember about the calibration of the battery:
- Once every 2-3 months, completely discharge the case and headphones (until automatic shutdown).
- Then charge to 100% without interruption.
- This helps to reset the errors of the charge controller.
