Owners of popular TWS-Xiaomi headsets often face the question of managing the power consumption of their devices. Many users, when purchasing a Redmi AirDots or AirDots 2 model for the first time, look for a physical button on the case to forcefully break the connection and save battery power. However, the design of modern fully wireless headphones implies a different approach to interaction with the user.
The basic philosophy of the Mijia line is to completely automate the process. You don't have to worry about manual power management in most use cases. The system itself detects when the device is no longer needed and puts it into deep sleep mode. This is done for maximum convenience: take it out of the case โ and the music plays, remove it back โ charging goes.
However, there are situations where the standard algorithm fails or requires a forced reboot of the Bluetooth module. Understanding the principles of sensors and the mechanics of the charging case will help you effectively manage the operation of the accessory. In this article, we will discuss all the nuances of disconnection, including hidden functions and methods of resuscitation of the device.
Principle of operation of automatic shutdown
The main mechanism that the owner should be interested in is the automatic shutdown when you put the headphone in the charging box. Inside the Redmi AirDots case, there are special contacts and magnets. When you put the headphone in the recess, the magnets lock it, and the contacts close the charging circuit.
At that point, the headphone lights up in red to signal the start of the energy storage process, and at the same time, the connection to the phone breaks, the headphone "knows" that it's in a safe place, and turns off the radio module, which is the standard way to turn off.
โ ๏ธ Note: If the indicator does not turn red after placing the headphone in the case, then the charge has not started, in which case the device can continue to consume energy and remain in pairing mode, which will lead to a rapid discharge.
There's also an off-case standby mode. If you pull out your headphones but don't plug them into your phone for 5 minutes, they'll go into power saving mode. However, a full shutdown in this scenario only happens after an hour of downtime. This is important to consider if you accidentally pull the gadget out of your bag.

Always check if the earphone is tightly stuck in the case, even a millimeter gap can prevent charging and automatic shutdown.
Manual shutdown and sensor control
Although there is no direct Power button on the body, users can control the state of the device through a multi-touch panel. Long-term tapping on the touch area allows you to execute various commands, but you can not directly turn off the earphone in this way in standard firmware.
To force the connection to break without being placed in the case, you can use the Bluetooth shutdown function on the smartphone itself. When the phone stops broadcasting the signal, the headphones will also go into sleep after a certain time, which is useful if the case is discharged or lost.
Some firmware versions allow you to reassign actions when holding the sensor, and you can check this through the Mi Wear app or Xiaomi Earbuds. If you have a long-press shutdown option in the settings, you're in luck. Otherwise you'll have to rely on automatic algorithms.
- ๐ Single touch โ pause or playback of a track.
- ๐ Double touch โ answering a call or activating a voice assistant.
- ๐ Triple touch โ skipping a track or completing a call (depending on the model).
- ๐ Sensor retention โ Calling the voice assistant or reducing the volume (depending on the side).
It's important to understand the difference between turning off and going into pairing mode. If you want your headphones to be no longer visible to other devices, you need to turn them off (put them in a case) or reset them. Simply turning off Bluetooth on your phone is not enough to hide the device from outside scanners.
Using a charging case for power management
The Redmi AirDots charger is not just a storage case, it's a battery health control center, and it's the capacity and serviceability of the case that determines how effectively your headphones will sleep, and inside the box is your own battery and power controller.
When you close the case cover (in models where it is) or just put the headphones inside, they go into charging mode. The indication on the front of the case shows the residual charge of the case itself. If the case indicator does not burn when it opens, then its battery is empty, too.
| Status of headphone indicator | Meaning | Action. |
|---|---|---|
| Burning red. | Charging's coming. | Leave it in the case. |
| Burning white. | Charged/ Ready to go | We can use it. |
| Blinks white | Search mode/Conjugation | Connect to the phone |
| It's not burning. | Discharged or off | Check the contacts |
There's a nuance to the contacts, and over time, metal can oxidize on the gold patches of the headphones and inside the case, or dust can accumulate, and this causes the device to not "understand" that it's in the case, and not turn off, and regular wiping of the contacts with a dry cloth or cotton swab lightly moistened with alcohol solves 90 percent of these problems.

Forced reset and reset of the device
If the headphones are stuck, not turned off or mated, you need a hard reset procedure, which is the analog of turning off the power and then cleaning the memory of the module, which returns the device to the factory settings.
To perform resets on Redmi AirDots and AirDots 2, you need to use touch panels. The procedure requires precision and a certain sequence of actions. Don't be afraid to press long, the sensors are protected from accidental activation.
1. Remove the headphones from the case.
2.Push and hold the sensors on both headphones at the same time.
3. Hold for about 20 seconds until the indicators flash red 2-3 times.
4. Release the sensors when the indicators light up white.After this procedure, the device completely forgets its previous connections and turns off, so to start using them again, you need to remove the device from the Bluetooth list on the phone and perform the pairing again, which often helps if one earphone stops working or the sound becomes quiet.
โ ๏ธ Warning: After resetting all settings, the headphones can start working independently of each other (mono mode). To restore stereo mode, place both earphones in the case, close it and open again in 10 seconds.
Problems with spontaneous inclusion
A common complaint of users is that the headphones turn on on themselves in your pocket or bag, due to sensor sensitivity or button sticking (in wired versions, although this is about TWS). In the case of AirDots, the reason is more often due to vibration or accidental touch.
To avoid battery discharge in your bag, always keep the headset in a closed case. If the case is open, the headphones can be activated from movement. Some users recommend using protective silicone cases on the case itself, which tightly close the lid.
Why are the headphones beeping?
It's also worth checking if the sensor is permanently clamped, if there's sulfur in the ears or if earwax is in the touch zone, it can simulate a tap, and if regular ear hygiene and earbud cleaning prevent false positives.
Features of different models of Redmi AirDots
Redmi's lineup is constantly updated, and the controls may vary from one version to the next. For example, in AirDots 3 or Basic, the sensor logic may be changed by the manufacturer.
Active noise cancellation (ANC) models may have separate operating modes that require manual switching, and in such devices, shutdowns may take longer because of the need to stop microphones and processors.
- ๐ง AirDots 1 โ classic scheme, reset by long press.
- ๐ง AirDots 2 โ Added a wear sensor (in some versions) that speeds up the response.
- ๐ง AirDots 3 โ Support for aptX codec, more complex logic of energy saving.
- ๐ง AirDots Pro โ Active noise reduction requiring separate shutdown.
If you have a newer model, it may support fast pairing via a pop-up on Xiaomi and Redmi smartphones.In this case, the shutdown can also be duplicated on the phone lock screen, if the appropriate app is installed.

The best way to turn off Redmi AirDots is to put them in a charging case. All other methods are assistive or emergency.
