Moisture getting inside a smartphone is a stressful situation for any owner, especially when it comes to modern Xiaomi models with non-removable batteries. Unlike older devices where you could instantly remove the battery, it requires a completely different algorithm of actions aimed at minimizing the oxidation of contacts. The first minutes after contact with water are critical, and it depends on the further viability of the gadget.
Modern flagships and budget brand often equipped with protection on the standard IP68 or IP53, but these figures do not mean complete waterproof. The adhesive, sealing the case, over time loses its properties, and the water pressure when diving can exceed the estimated. If you drop the device in the sink, caught in a shower or just dropped it in a glass, you need to act immediately and in cold blood, ignoring the panic.
The main danger is not the fact of getting wet, but the electrochemical corrosion that is triggered when the voltage is applied to the wet boards. In Redmi and Poco devices, the density of the elements is extremely high, making them vulnerable even to microscopic droplets. Your task now is to de-energize the system as quickly as possible and create conditions for natural evaporation of moisture without the use of aggressive heating methods.
The first steps immediately after contact with water
The first thing you need to do is turn off the device immediately. If the screen reacts, don't try to flip through the menu, just press the power button until it's completely turned off. In non-removable models, you can't physically turn off the power without disassembling, so software shutting down is the only way you can interrupt the motherboard's current.
⚠️ Warning: It is strictly forbidden to connect a wet phone to a charger! applying voltage to wet contacts is guaranteed to cause a short circuit that can disable the power controller or motherboard itself.
After turning off, remove the tray for SIM-This action has two functions: it opens an additional channel for air circulation inside the enclosure and saves your data on an external drive if water gets to it. Do not shake the device sharply to “drive” the water, as this can carry moisture through the internal compartments, where it has not yet reached.
Carefully wipe the outer surface with a soft, moisture-absorbing cloth or paper towel. Pay special attention to the charging connector, speakers and microphones. Using cotton swabs to remove moisture from the charging ports is only permissible if they are completely dry and leave no villi. Any remaining villi can soak up water and create a conductive bridge inside the connector.

The main goal of the primary actions is to completely de-energize the device and remove visible moisture from external ports without water penetrating deeper into the housing.
What you can not do when drying
There are many myths about how to save a wet gadget, but many of them can do more harm than water itself. The most common and dangerous is the use of a hair dryer. The hot air flow not only drives moisture deeper into the device, but can also melt the glue, holding the display and back cover, and damage the device. OLED-a matrix that is extremely sensitive to overheating.
- 🚫 Hair dryer: Hot air destroys the oleophobic screen covering and can deform plastic elements inside the enclosure.
- 🚫 Microwave or oven: Absolutely unacceptable methods that will lead to the bloating of the lithium polymer battery and possible fire.
- 🚫 Charging: Trying to check if the phone is “live” by connecting it to the network is a surefire way to finally kill electronics.
Another popular mistake is putting your smartphone in a container of rice. Rice dust, which inevitably enters connectors and speakers, mixes with moisture and turns into adhesive mass that clogs contacts. In addition, starch is a dielectric and can disrupt the sensor, and its hygroscopicity in this context is greatly exaggerated compared to specialized silica gel granules.
Why is rice a bad idea?
Effective methods of drying Xiaomi at home
The safest and most effective way to remove moisture is to use silica gel, which are the very small bags that are often put in boxes of shoes or new electronics. Silica gel is a powerful adsorbent that can pull moisture out of the air, creating a dry environment around the device. Place the phone in a sealed container with a large number of such bags.
If silica gel is not available, you can use a soft air circulation method. Put the phone on a flat surface in a dry, warm room (but not on the battery!). You can point the fan at minimum power to ensure a constant flow of dry air to the open ports. The evaporation process in this case will take longer, but will be safe for the components.
☑️ Safe drying algorithm
It is important to ensure that the device is positioned correctly. It is best to place it horizontally or at a small angle so that water can flow by gravity to the holes if it is at the entrance. Do not put the phone vertically with the screen down, as moisture can leak under the display and damage the plumes.
Comparison of drying methods: efficiency and risks
To understand the consequences of different actions, we should consider a comparison table of popular methods, which will help assess risks and choose the most rational strategy for emergency behavior.
| Method | Efficiency | Risk of damage | Recommendation |
|---|---|---|---|
| silicagel | Tall. | Minimum | Recommended |
| Fen (hot) | Low. | critical | Forbidden. |
| Rhys | Low. | Medium (dust) | Not recommended |
| Natural drying | Medium | Minimum | Safe. |
As you can see from the table, the use of specialized absorbent agents gives the best result without side effects. High-temperature methods carry the risk of irreversible damage to the polymer battery and adhesive compounds.
How long does it take to dry completely?
The time required to evaporate moisture depends on the amount of liquid that enters the device and the humidity of the environment. The minimum period that the device must lie off in a low humidity environment is 24 hours.
Even if it looks dry from the outside, moisture can remain under the CPU shields or in hard-to-reach areas of the board. Attempting to start 2-3 hours after getting wet often leads to fatal consequences, as residual moisture closes the contacts when the voltage is applied.
If the device does not turn on after 48 hours of drying, it does not always mean its death, it may be oxidized contacts of the power button or the protection has gone off, in which case further self-activation attempts may be useless and a diagnosis will be required at the service center.
Signs of moisture and the need for service
Even if the phone is successfully turned on after drying, you need to carefully monitor its behavior. There are hidden signs of moisture that can manifest after a while. Pay attention to the speaker: wheezing or distortion of sound often indicate residual moisture in the membrane or oxidation of contacts.
- 👁️ Condensation under the camera: fogging of the lenses indicates high humidity inside the camera module.
- 🔋 Fast discharge: oxidized power chains can cause current leakage and abnormal battery behavior.
- 📶 Network problems: signal loss or poor reception may indicate corrosion of antenna contacts.
Inside the case of most Xiaomi smartphones, special LCI (Liquid Contact Indicator) litmus indicators are installed. When in contact with water, they change color from white or silver to red or pink. If you see a change in color of the indicator (usually visible through the SIM tray or when disassembling), this confirms that moisture is injected.
⚠️ Warning: The presence of a moisture indicator is often a reason for refusing warranty repairs, since the water case is not covered by the manufacturer's standard warranty.
If you notice any abnormalities in the operation of the device after drying, it is better not to take risks and consult specialists. Professional cleaning in an ultrasonic bath using special reagents is able to remove oxides and prevent further corrosion, which can "eat" the fee in a few weeks.
💡
Use compressed air (cylinder) to neatly blow droplets out of the speakers, but do not bring the nozzle close to the mesh so as not to damage the membrane with pressure.
