Xiaomi AirDrying Mode: What It Is, How It Works, and Why It Works

Introduction: why Xiaomi has added a drying mode in smartphones

Owners of Xiaomi smartphones of the latest generations may have noticed in the settings of the mysterious item "Air Drying Mode"** (or AirDry Mode), this feature appeared not by chance: according to statistics of service centers, it is not possible to use the system in the first place. 30% Smartphones break down because they get moisture, whether it's rain, condensate, accidental water dipping. IP53/IP68 not immune to corrosion of contacts with prolonged exposure to a humid environment.

AirDry is a hardware-software solution that helps speed up the evaporation of moisture from the inside of a smartphone without disassembling. Unlike the classic rice-drying or silica-gel drying, it involves fans, battery heating and power management algorithms. But how does it work, and how effective is the function in practice? Let's take a look at it from theory to step-by-step instructions.

What is air drying mode (AirDry) in Xiaomi: technical details

AirDry mode is a set of measures that are activated when moisture is detected inside the smartphone body, and it is based on three key mechanisms:

• 🔥 Controlled Heating: CPU and battery briefly raise temperature to 40-45°C, accelerating evaporation of moisture. Temperature is regulated by sensors to avoid overheating.
• 🌀 Activation of ventilation: in models with active cooling (for example, Xiaomi Black Shark or other models). POCO F6 Pro) built-in fans for air circulation are used.
• ⚡ Power restriction: non-critical modules are turned off (NFC, secondary cameras), and charging is blocked until completely dry to avoid short circuits.

It's important to understand that AirDry is not a substitute for physical drying, it's an additional measure, for example, if a smartphone falls into water, it still needs to be removed, turned off and dried with an absorbent material (such as microfiber), while the mode helps to get to moisture in hard-to-reach places: under the display, near the speakers or in the connector USB-C.

💡

If after activation of AirDry smartphone began to warm up stronger than usual, it is normal. the main thing is not to cover it and do not put it on soft surfaces (pillows, blankets) so as not to block the heat sink.

How does a smartphone determine the presence of moisture?

Xiaomi devices use two types of sensors:

1. Capacitive sensors in the connector USB-C and under the grid of speakers - react to a change in dielectric permeability when water enters.
2. Algorithm of humidity analysis (in models with IP68) — tracks the resistance of contacts on the board and compares with reference values.

If the sensors are triggered, the system displays a warning such as "Moisture detected in the charging connector" and suggests that AirDry be enabled, MIUI 14+) activate automatically.

What Xiaomi models support AirDry mode?

AirDry is not available on all Xiaomi devices. 2022 This is the year and applies to flagship and gaming models with improved cooling system. Below is the compatibility table (relevant for firmware). MIUI 14/15 hyperos):

If your model isn't on the list, it doesn't mean it doesn't support drying at all. For example, in the Redmi Note 12 Pro.+ There is a simplified analogue - "Moisture Protection"** (Moisture Protection), which blocks charging until the connector drys out, but does not heat the battery.

How to check for a function on your device

To find out if AirDry is in your smartphone, follow the following steps:

Open the Settings. → The phone. → Version. MIUI|Tap 5 times on the kernel version line (to unlock hidden menus)|Go to Settings. → Additionally. → Special facilities → Drying mode|If there is no item, check the firmware updates.-->

If the menu is missing, but the smartphone hit the table above, try updating the firmware to the latest version. MIUI In some regions, the function may be disabled at the software level (for example, in European firmware Redmi).

How to turn on and off the air drying mode on Xiaomi

The process of activating AirDry depends on the model and version of the firmware, and below is a universal instruction that is suitable for most devices.

Manual switching on (if the smartphone does not detect moisture automatically)

1. Go to Settings. → Battery and productivity → Drying mode (or Settings) → Additionally. → AirDry mode).
2. Press "Run" and confirm the action. The system will prompt you to turn off the smartphone from charging (if it is connected).
3. Wait until the process is completed (usually 30-60 minutes) and the progress indicator will be displayed on the lock screen.

During AirDry's operation:

• 🔋 Battery charging is blocked (even if the cable is connected).
• 📵 NFC, Bluetooth and secondary cameras can be temporarily shut down.
• 🔥 The temperature of the body is rising – this is normal.

Automatic on (when moisture is detected)

If the smartphone detects moisture in the connector USB-C or under the speakers, a notification will appear:

⚠️ Attention: moisture is detected in the charging connector, the cable connection may cause damage to the device?

Press Yes, and the process will start automatically. In some models (such as the Xiaomi 14 Ultra), drying is activated without request.

How to turn off the regime early

If you need to interrupt AirDry (for example, urgent charging is required), do the following:

1. Hold the power button for 10 seconds to force the device to restart.
2. After restart, go to Settings. → Drying mode and press "Cancel».

What to do if AirDry doesn't help: alternative drying methods

AirDry mode is effective for a slight ingress of moisture, but if the smartphone has been in water for a long time or moisture has penetrated deeply (for example, under the screen), additional measures will be required.

Steps to Save the 'Drowned'

1. Immediately remove the smartphone from the water, turn it off and remove it. SIM-map + memory-card.

Don't turn the device on.

48 hours.

If after drying the smartphone does not turn on or malfunctions (for example, the sensor does not respond or speakers do not work), contact the service center.

💡

AirDry mode speeds up evaporation, but does not guarantee 100% protection. In case of severe flooding, combine it with classic drying methods (silica gel, ventilation).

When to contact the service center

Make an appointment for diagnosis if after drying there are:

• 🔳 Artifacts on screen (strips, flickering, broken zones).
• 🔊 Distorted sound or lack of sound in speakers.
• 🔋 Fast battery discharge (moisture could damage the power controller).
• 📶 Network problems (not catching Wi-Fi or mobile communication).

Xiaomi service centers use ultrasonic baths and special solutions that cannot be used at home to remove moisture. The average cost of such a service is 1,500-3,000 ₽ (model-wise).

Frequent Mistakes and Myths About AirDry

There's a lot of misconceptions about AirDry, and we're going to look at some of the most common ones.

Myth 1: AirDry Dries Smartphones in 10 Minutes

In fact, a full cycle takes 30 to 90 minutes, and in complex cases (like after being submerged in water) it may take several reruns.°C+ Dangerous – This can damage the battery.

Myth 2: “The mode only works with the original firmware.”

AirDry's function is tied to hardware (sensors, cooling system) and not to firmware. ROM (For example, LineageOS, the power menu may not be available, in which case the mode still activates automatically when moisture is detected.

Myth 3: AirDry is ruining the battery

Short-term heating to 40-45°C is not critical for today's lithium-ion batteries, compared to the fact that in intense play, the battery temperature can reach 50.°However, it is not recommended to run AirDry more than 1 time per month without the need to.

💡

If you use AirDry frequently (for example, due to high humidity in the room), check the battery status in the Settings menu. → Battery → Battery status. If the capacity drops below 80%, consider replacing it.

Mistake: Ignoring Moisture Warnings

Many users close the notification "Detected moisture in the connector"** and continue to charge the smartphone.

• ⚡ Short circuit on the board (especially if moisture got on the power contacts).
• 🔋 Battery bloating due to corrosion of the charging controller.
• 📱 Warranty loss – traces of moisture are recorded by indicators (Liquid Damage Indicators, LDI).

⚠️ Attention: if after ignoring the warning, the smartphone stopped charging, do not try to "dry" it with a hair dryer or on the battery.

Comparison of AirDry with analogues from other brands

Xiaomi isn’t the first company to introduce software drying, such as Samsung’s “Water Ejection” technology in Galaxy smartphones. S22/S23, Apple is the “Liquid Detection” on the iPhone 12–15. Compare them to AirDry:

The main advantage of AirDry is its integrated approach: it not only warns of moisture, but also actively combats its effects, but Samsung benefits from the vibration method in terms of the speed of drying connectors.

Which is better: AirDry or classic drying?

The best option is a combination of both methods:

1. First, wipe your smartphone with a microfiber and place it in a dry place with ventilation.
2. Run AirDry to remove moisture from hard-to-reach areas.
3. If after 2-3 hours the warning about moisture has not disappeared, repeat the procedure or use silica gel.
