The problem with determining the status of charging the Xiaomi Mi True Wireless Earphones case is familiar to many owners: the manufacturer does not always describe the nuances of the display in detail. As a result, users wonder whether the case is 100% charged or the process is still underway, especially for Mi True Wireless Earphones 2, Mi True Wireless Earphones Basic 2 and early versions, where the notification system is minimalistic.
In this article, we will explore all the possible ways to test a case charge, from standard light indicators to hidden mobile app functions, and explain why a case can falsely signal a full charge and how to avoid it.
Note that the full charge time of the case depends on the model. For example, for Mi True Wireless Earphones 2 with a battery capacity of 300 mAh, it is ~2 hours, and for the Basic version it is up to 2.5 hours. If your case charges longer, this is an occasion to check the cable or power supply.
1. Light indication: what do colors and blinkings mean
The main way to determine the status of charging is the LED on the front panel of the case. All models Xiaomi Mi True it works on the same principle, but there are nuances:
π΄ Red color (constantly burning or flashing):
- π Burning constantly - the case is charged, the battery level is lower 80%. For Mi True. 2 This means that there is still a full charge. ~30-40 minute.
- β‘ Blinks with pauses β critically low charge (less than 10%), in which case the case may not sound when the headphones are connected.
π’ Green (constantly burning):
- β Burning without blinking - the case is charged on 100%. For models with USB-C The green indicator appears through ~1.5-2 hour after charging.
- π Flashing green β a rare situation that indicates a charging error (such as a faulty cable or contaminated contacts).
βͺ White color only for Mi True 2):
- π It burns when you plug in to the power -- the case identified the source of the charge and started the process. 5-10 The indicator will change to red/green.
Mi True Wireless Earphones Basic 2 doesnβt have a white indicator, and the case immediately shows red or green depending on the charge level.
β οΈ Warning: If the indicator goes out during charging, check the cable and power supply. 5V/1A, And the case doesn't recognize charging. Use the original Xiaomi cable or the certified one. USB-C.
2.Audio signals: what they mean
Xiaomi Mi True cases make sounds not only when you connect your headphones, but also when you charge, signals that are often ignored, but they help diagnose problems:
π Single beep when connected to power:
- π Short high sound, the case starts charging, similar to the white light on Mi True 2.
- π« No sound, there may be problems with the case contacts or the cable. USB-C cotton-rod.
π Double signal through 10-15 charge-minutes:
- β Two short sounds - the case charged to 50-60%. This is the intermediate stage, after which the indicator will change from red to green.
π Long signal (3-5 seconds):
- β οΈ Continuous squeaking is a charging error, most often caused by using non-original adapters with a voltage higher than the current. 5V.
- π Sound when disconnected from power - the case is fully charged (analogue of a green indicator).
π‘
If the case is making noises but the indicator is not on, try connecting it to another power source (for example, a laptop), perhaps the power supply does not give enough current.
3. Check through the mobile application Mi Home
The official Mi Home app (or Xiaomi Wear for new models) displays the charge level of the case and headphones.
- π± The app only shows the charge when the headphones are connected. If the headphones are in the case, the data may not be updated.
- π The latest version of the case firmware is required to work properly. Check the updates in Mi Home β Device profile β Update of the PO.
π How to check the charge of the case through Mi Home:
β οΈ Application errors:
- π« If the application shows 0%, but the case is charged by the indicator β restart Bluetooth on your smartphone.
- π If the percentage βhangsβ by 99% β turn off and reconnect the headphones to the phone.
Why can't the app show the case charge?
Table: charging time and indication for different models
The full charge time of the case depends on the model and the power source. Below is a comparison table for the popular versions of Xiaomi Mi True:
| Model | Case battery capacity | Charging time (0β100%) | Indication of 100% charge | Features |
|---|---|---|---|---|
| Mi True Wireless Earphones 2 | 300 mAh | ~2 hours | Green indicator + long sound | Supports fast charging of 5V/2A |
| Mi True Wireless Earphones Basic 2 | 300 mAh | ~2.5 hours | Green indicator (no sound) | There is no white indicator when connecting |
| Mi True Wireless Earphones (Version 1) | 350 mAh | ~3 hours | Green indicator + double signal | Sensitive to the quality of the cable |
| Mi True Wireless Earphones 2S | 400 mAh | ~1.5 hours | White β green-light | Supports Qi wireless charging |
π‘
Cases Xiaomi Mi True with a capacity above 350 mAh (for example, 2S) charge faster thanks to the support of current 2A. Use an adapter with the appropriate characteristics.
5. False indication: why the case shows 100%, but quickly discharges
A case showing a green light after 30-40 minutes of charging, but actually only 60-70% of charging, occurs in 15-20% of users.
π Worn-out case battery:
- π If the case is bigger 2 In the years since, the battery capacity has decreased. 30-40%. Check the real charge with Mi Home.
- π Decision: Follow up 2-3 full discharge/charging cycle (from 0% before 100%) controller-calibration.
β‘ Unoriginal cable or adapter:
- β οΈ Cheap cables may not provide stable voltage, which is why the case controller mistakenly captures full charging.
- π Solution: Use Xiaomi Cable with Labeling 5V/2A certified USB-C.
π§² Contact contamination:
- π Dust or oxidation on contacts USB-C The case may "think" that the charge is complete.
- π§Ό Solution: Clean the connector with a cotton swab dipped in alcohol (at least 70%).
Try another cable and adapter | Clear USB-C contacts | Check the charge via Mi Home| Calibrate the battery (discharge to 0% and charge to 100%) |Update the case firmware-->
6. Alternative methods of charge checking
If standard methods donβt work, try these options:
π Connection to PC:
- π» When connecting the case to the computer through USB-C Device Manager (Windows) or System Information (macOS) will display the device name and current charging current.
- β‘ If current 0 Me, the case is not charging. 300-500 MA -- charging's coming.
π± Use of third-party applications:
- π Apps like Battery Widget Reborn (Android) or CoconutBattery (iOS) can show the charge of Bluetooth accessories, including cases.
- β οΈ The accuracy of such applications is lower than that of Mi Home, but they help in the absence of official software.
π Discharge test:
- β³ Charge the case fully (by the indicator), then use the headphones until discharge. If the case holds a charge for less than 12 hours, its capacity is reduced.
- π For Mi True. 2 case-time β 18-20 hours 3-4 headphone charging cycles).
β οΈ Note: If the case is discharged for 4-5 When you're in active use, it's a sign of a power controller malfunction, and then you can only change the case board at the service center.
7. Frequent mistakes and how to avoid them
User experience shows that 80% of the problems with charging the Xiaomi Mi True case are due to improper operation.
π« Using βfastβ charging from smartphones:
- β‘ Quick Charge or Power Delivery adapters can deliver higher voltages 5V, Which causes the case controller to fail.
- π Solution: Use a fixed voltage adapter 5V/1A or 5V/2A.
π₯ Charging at high temperatures:
- π‘οΈ If the case is heated above 40Β°C (e.g., in the sun or near heating appliances), the controller may turn off charging.
- βοΈ Solution: Let the case cool to room temperature before connecting to power.
π Interruption of charging on 90-95%:
- π Some cases (especially Mi True Basic 2) are 95% freeze-free due to firmware features.
- β³ Solution: wait a minute. 20-30 In the minutes, the indicator will change to green.
π‘
If the case does not charge for a long time, try to βresetβ its controller: connect to the power, then press and hold the pairing button on the case for 10 seconds.
