How to check the charge of the case of Xiaomi headphones: from indicators to hidden functions MIUI

Charging the Xiaomi wireless headphone case is one of those little things that can ruin the day at the most inopportune moment: You take out your headphones to listen to music on the subway or on a run, and they're discharged because the case is sitting in the backpack. Or vice versa: you plug your headphones into your phone, and the warning on the screen about the low battery level of the case, even though you were sure you charged it yesterday.

The problem is that the manufacturer doesn’t always make the charge indication obvious. Depending on the headphone model (Redmi AirDots, Xiaomi Buds, FlipBuds, etc.), the methods of checking can be radically different: Somewhere you have an LED indicator, someplace you need to use a proprietary app, and in some cases you have to puzzle over voice prompts. In this article, we will discuss all the current methods for checking the charge of the case for Xiaomi headphones, including little-known chips. MIUI and workarounds for old models.

Important: If your headphones don't hold a charge or your case is discharged too quickly, the problem may not be the software, but the hardware. At the end of the article, there's a section with typical malfunctions and how to diagnose them.

Indicators on the case: what do flashing lights mean

The most obvious way is to look at the LED lights on the front of the case, but there are a few nuances.

  • πŸ”΄ Red is a case charge below 20%. On some models (Redmi AirDots 2, Xiaomi Buds 4 Lite), the red indicator flashes when connected to charging, signaling the beginning of the process.
  • 🟑 Yellow/orange – 20% to 50% charge, rarely seen, usually only on flagship models (Xiaomi Buds 4 Pro).
  • 🟒 Green: charge above 50%. Redmi AirDots 3 Pro uses a green light that burns at full charge (100%).
  • πŸ”„ Blinking white – case in pairing mode (does not show charge!). A common mistake of users is to confuse this indicator with the battery level.

On most budget models (Redmi AirDots S, Xiaomi Haylou) GT1) There's only one indicator, and it only displays the charge of the case when you plug it into the charger, so if you just open the case, the light won't light up. This is done to save energy, but it's uncomfortable.

⚠️ Attention: On Xiaomi Buds models 3T And the newer case charge indicator can go off 5 seconds after the lid is opened. If the light goes out too quickly, try closing and reopening the case.

If the indicator does not burn at all, check:

  1. Is the case connected to charging (in some models, the indicator is activated only when charging).
  2. Is the Type-C connector or wireless charging contacts contaminated (on Xiaomi Buds 3 Pro).
  3. Have you lost your settings after the firmware update (relevant to Redmi Buds 4 Active)?

2.Charge check via Mi Fitness/Xiaomi Wear app

Xiaomi's proprietary apps are the most reliable way to know the exact percentage of the case charge, but there are pitfalls:

  • πŸ“± Mi Fitness – supports most models (Redmi AirDots, Xiaomi Buds), but may not show the charge of the case on older versions (update the application!).
  • βš™οΈ Xiaomi Wear is a more modern app, but only works with new headphones (Buds 4 Pro, FlipBuds Pro).
  • πŸ”„ Data reset – if the application does not see the case, try to remove the headphones from the list of devices and connect again.

The following steps are taken for Mi Fitness:

Open the Mi Fitness app on your smartphone

Go to the Devices tab (bottom of the screen)

Choose your headphones from the list

On the main screen of the device, find the Battery Status section

Slip on the case icon - the percentage of charge will be displayed

If the application does not show the charge of the case, but the headphones are connected:

  1. Check if your model supports this feature (see the compatibility table below).
  2. Update the headphone firmware through Settings β†’ Update of the Software in the same annex.
  3. Reboot your smartphone – sometimes helps with Bluetooth glitch.

⚠️ Attention: On Android 12+ The Mi Fitness app may require additional permissions to display the charge level. β†’ Annexes β†’ Mi Fitness β†’ Permissions and enable Bluetooth access and Notifications.

3.Voice hints: how to hear percentage charge

Many Xiaomi headphones can voice the charge level of the case when connected to the phone, but this function does not always work and depends on:

  • πŸ“± Smartphone models (on Xiaomi/Redmi/Poco s MIUI works more stable).
  • πŸ”Š Versions of the firmware headphones (on older versions may not be available).
  • 🎧 Headphone models (on Redmi AirDots 3 Pro only the charge of the headphones themselves, not the case is voiced).

How to turn on voice prompts:

  1. Put the headphones on the phone.
  2. Open the case cover (the headphones should stay inside!).
  3. On some models (Xiaomi Buds 4 Pro) you need to tap twice on the touch panel of the case.
  4. The voice assistant will say, β€œCase charge level is 70 percent” (example for the case). MIUI 14).

If the voice prompts don't work:

  • πŸ”„ Update the headphone firmware through Mi Fitness.
  • πŸ“² Check the voice settings in Settings β†’ Sound. β†’ Voice assistant on a smartphone.
  • πŸŽ›οΈ Reset the headphones to factory settings (press the button on the case for 10 seconds).

πŸ’‘

On Xiaomi Buds. 3T And newer voice prompts work only when connected to smartphones on MIUI 13+. If you have a different brand (Samsung, iPhone), this method may not work.

4. Hidden functions MIUI: How to see the charge of the case in the notification curtain

If you have a Xiaomi, Redmi or Poco smartphone MIUI 12+, There's a way to see the case charge right in the notification curtain, and it doesn't work on all headphone models, but it's worth a try:

  1. Put the headphones on the phone.
  2. Open the Notification Curtain (swipe down from the top edge of the screen).
  3. Find a tile with an earphone icon (like Redmi Buds 4).
  4. Slip on the tile - a mini-panel with the level of charge of headphones and case will open.

If there is no tiles:

  • πŸ”§ Go to Settings. β†’ Notifications β†’ Control panel.
  • πŸ” Find your headphones in the list and add them to active tiles.
  • πŸ”„ Restart your phone if the tile doesn’t appear after adding.

Android 13.+ (including MIUI 14) this feature may not work as well due to Google's restrictions on accessing Bluetooth data, in which case only the proprietary Xiaomi Wear app will help.

Why? MIUI It doesn't always show the charge of the case?
Starting with Android 12, Google tightened the rules for apps to access Bluetooth data. MIUI It can't directly read the charge level of the case without proprietary software, so only the headphones themselves can be displayed in the notification curtain. To see the charge of the case, you need to use Mi Fitness or Xiaomi Wear, which have special permissions from the manufacturer.

5. Alternative methods: from widgets to third-party applications

If none of the above methods worked, you can try workarounds:

  • πŸ“² Android widgets – apps like Battery Widget Reborn or Bluetooth Battery Monitor can show the charge of the case, but require manual adjustment and are not always accurate.
  • πŸ”Œ Charger with display - some powerbanks (e.g. Xiaomi Power Bank 3 Pro) show the current consumed. If you plug in a case, you can estimate the charge level by the charging speed roughly.
  • ⚑ Tester USB-Ports are a cheap device for measuring voltage. When fully charged, the case consumes ~0.1A, when discharged, until 0.5A.

Instructions for Bluetooth Battery Monitor:

  1. Download the app from Google Play.
  2. Put the headphones on the phone.
  3. Open the app and select your headphones from the device list.
  4. Press Refresh – if the case supports charge data transfer, it will appear as a percentage.

⚠️ Note: Third-party applications may not read data from Xiaomi cases due to proprietary communication protocols. Do not rely on them in critical situations (for example, before a long flight).

For iPhone owners, the situation is even more complicated: Apple restricts access to Bluetooth data, so no third-party application will be able to show the charge of the Xiaomi case, the only way out is to use the indicator on the case itself or voice prompts (if supported).

Typical problems and their solutions

If the case discharges too quickly or does not show the level of charge, the reasons may be as follows:

Problem.Possible causeDecision
Case discharges overnightFailure of the battery or charge controllerCheck the case with a tester, replace the battery if necessary.
The indicator does not burn when chargingContact contamination or faulty cableClean the Type-C connector with alcohol, try another cable
The app doesn't show the case chargeOutdated headphone firmwareUpdate the software with Mi Fitness or Xiaomi Wear
Voice prompts are silentVoice assistant disabled in MIUIEnable in Settings β†’ Sound. β†’ Voice assistant
Case doesn't charge headphones.Wear of contacts inside the caseContact the service center to replace the spring contacts

If the case does not hold the charge at all (discharges for the case) 1-2 The problem is probably the battery. Most Xiaomi models have a case battery that is designed to be used for the battery. 300-500 And then the capacity drops down. 30-50%, And the case has to be charged every day.

How to check the wear of the battery:

  • πŸ”‹ Use the AccuBattery application (if the case supports data transfer).
  • βš–οΈ Weigh the case on a precise scale - the difference between a new and worn-out battery can reach 2-3 gram.
  • πŸ”Œ Connect the case to the charger and record the full charge time if it's increased at 2.+ Once, the battery degraded.

πŸ’‘

If the case Xiaomi discharges for 1-2 The day is not used, and the headphones are not charged until 100% β€” This is a sure sign of battery wear, and in this case, only a replacement battery at the service center will help.

7.How to extend the life of a case battery: operating tips

To make the case last longer, follow these recommendations:

  • πŸ”Œ Do not leave the case on charging for more than 24 hours - this accelerates the degradation of the lithium polymer battery.
  • 🌑️ Avoid extreme temperatures – do not store the case in the sun or near the heating battery.
  • πŸ”‹ Charge the case to 80-90%, If you do not plan to use it for a long time (the best level for storage).
  • 🧹 Clean contacts inside the case and on headphones with a soft brush once a month.
  • πŸ”„ Update the firmware of headphones – new versions often optimize power consumption.

For models with wireless charging (Xiaomi Buds 3 Pro, FlipBuds Pro):

  • πŸ“΅ Do not put the case on the charging station if it is already 100% charged - this leads to overheating.
  • πŸ”„ Use only certified Qi chargers (no more power) 10W).

If you use the case intensively (for example, listen to music on the Internet). 5-6 Every day, try once in a while. 3 discharge it 0% load up 100%. This helps calibrate the battery controller and prolongs its life.

FAQ: Frequent questions about the charge of the Xiaomi case

πŸ”‹ Why the case is discharged, even if the headphones are not used?
The case consumes energy to maintain Bluetooth communication (if the lid is open) and to power internal circuits. In sleep mode (the lid is closed), the flow is minimal, but if the case lies for months without recharging, it can run out, and the cause may be a faulty power controller or a worn-out battery.
πŸ“± Can I check the charge of the case on the iPhone?
There is no standard way to see the charge of the Xiaomi case on the iPhone. The only options are: Use the indicator on the case itself. Listen to voice prompts (if supported by your model); Install the Mi Fitness app, but it works unstable on iOS. Apple restricts access to Bluetooth data, so third-party apps won't help either.
⚑ How long should the case be charged?
Charging time depends on the model: Redmi AirDots, Xiaomi Buds 4 Lite β€” 1.5-2 hourly 0 before 100%). Xiaomi Buds 4 Pro, FlipBuds Pro β€” 1 Older models (Redmi AirDots S) - up to 3 If the case charges longer 4 Check the cable, power supply and clean Type-C connector.
πŸ”„ How to Reset Charge Data if Case Shows Wrong Percentage?
If the case suddenly began to show 0% or 100% for no reason, calibration will help: Discharge the case until it is completely turned off (do not open the lid until it sits). Connect to the original charger and charge to 100% Turn it off and reconnect the case, the controller will recalibrate. If that doesn't work, reset the headphones to the factory settings (press the button on the case on the case). 10-15 seconds).
πŸ› οΈ Can I replace the battery in the case by myself?
Theoretically, yes, but in practice, it is risky: πŸ”§ You will need a soldering iron and experience with small electronics. πŸ”‹ The new battery must be an exact copy of the original (in terms of capacity and size). ⚠️ If you do not replace the case can stop charging headphones or even burn. If you are not sure of your skills, it is better to contact the service center. The cost of replacing the battery case in official Xiaomi services is from 800 to 1500 rubles (depending on the model).
