When Xiaomi falls into the water, it causes panic in any owner, especially if the device stops responding to commands. Water is an excellent conductor of electricity and a catalyst for chemical reactions, so the count goes literally for minutes. If your smartphone is in the liquid, the speed and correctness of your actions will determine whether you can save the motherboard from irreversible corrosion.
Modern models often have a label of moisture protection, but this does not provide a complete guarantee of survival in full immersion. The pressure of the liquid column can push through the protective membranes, and salt or chlorinated water accelerates the destruction of contacts at times faster than fresh water, which is why you can not ignore the ingress of moisture inside the case, even if the gadget formally continues to work.
The first thing you need to realize is that the water inside the enclosure poses a risk of short circuits when power is applied. Any attempt to turn the device on or test the charge while there is moisture inside can be fatal to the electronics. Further actions should be aimed solely at minimizing damage and safely removing fluid from hard-to-reach areas.
Primary Actions: The Emergency Algorithm
Once you've removed the device from the water, your main task is to turn it off. If the screen is still on or the light is flashing, immediately press the power button to force it to turn off. Don't try to unlock the phone, flip through the menu or check the applications. Every second the chips work in contact with water increases the likelihood of short circuits.
If your Xiaomi has the ability to retrieve SIM-And if you have a card or a memory card without any special tools, do it immediately. The tray often serves as an additional channel for moisture to enter, and opening it will help to lower the internal pressure slightly and give the water an exit.
☑️ Emergency actions in case of water intrusion
Remove all external accessories: protective cover, ring holders and glass. Under the case, moisture lasts the longest, creating the perfect environment for oxidation. Gently wet the case with a soft, lilaless cloth or paper towel. Don't rub aggressively, so as not to drive the drops deeper through speakers and microphones.
⚠️ Attention: It is strictly forbidden to connect the smartphone to the charger or computer through USB-the cable until you're sure there's no moisture inside the connectors, and applying the voltage to the wet board is guaranteed to cause the power controller to burn.
What not to do: common mistakes
There are many myths surrounding the wet phone that often end up being a complete technology, the most dangerous of which is the use of a dryer, and the flow of hot air not only doesn't pull moisture from the bottom of the case, but can also melt the adhesive layer that seals the screen, or damage the delicate plumes.
Another big mistake is trying to dry in the microwave, which is absolutely unacceptable, because the metal inside the smartphone will cause sparking, which will cause the battery to explode or the motherboard to completely fail, and you should not put your phone on working heaters or leave it under the scorching sun: overheating of the lithium polymer battery is dangerous to fire.
Many users start shaking their phones or rattling their hands to try to knock out the water, which is not worth it. Sharp movements can spread the droplets to all the corners of the board, reaching areas where water itself might not have gotten, and vibration can displace small components or tear off sluggish contacts.
💡
Do not use cotton swabs to clean the charging connector if it is wet. Villi can get stuck inside and create a conductive bridge when wet.
The process of proper drying: methods and means
Once the external moisture is removed and the device is turned off, the passive drying phase begins, and the most affordable and safe method is to use silica gel pellets, these are the very small bags that are often in boxes with new shoes or electronics, and they are highly hygroscopic and effectively draw moisture.
Place the phone in a sealed bag or container with lots of silica gel. Make sure the device is completely surrounded by granules. If there is no silica gel, you can use raw rice, although its efficiency is lower, and dust from the grains can clog the speakers. The time of such drying shall not be less than 48 hours, and ideally until 3-4 day-day.
Why is rice worse than silica gel?
When drying, gently flip the device every few hours, changing its position, which will help gravity move the droplets to the holes where they can evaporate, and don't try to speed up the process by turning on the phone every half hour to check, which will negate all efforts.
⚠️ Warning: If the phone falls into salt water, sweet soda or beer, drying it won't help. Salt and sugar are krillized on the board, causing corrosion even after drying.
Diagnosis after drying: signs of damage
48 hours later, you decide to turn on the device. Take your time. Carefully inspect the charging connector and speaker for any moisture or white plaque leftovers. If everything is dry, try pressing the switch. Lack of response is the first sign that the problem is more serious than just water in the dynamics.
Pay attention to the indicators of water protection (LCI). In Xiaomi smartphones, they are often located inside the tray. SIM-It's white or silver when it's dry, but when it comes in contact with water, it turns bright red.
If the phone is turned on, conduct a full diagnosis of the functionality:
- 📱 Check the touchscreen across the screen area for "dead zones".
- 🔊 Test speakers and microphone by making a test call or recording a voice.
- 📷 Launch the camera and check if there is fogging under the lenses or focus module.
- 🔋 Track the battery discharge rate – oxidation can cause abnormal energy consumption.
The appearance of strange artifacts on the screen, spontaneous reboots or heating of the lower part of the body (where the processor is located) indicate that the oxidation process has begun, in which case the use of the device should be stopped before repairs are carried out.
Table of symptoms and probable causes
Understanding the symptoms helps determine the scale of the disaster, and below is a table that will help classify your gadget's condition after contact with water.
| Symptoms. | Probable cause | Level of danger |
|---|---|---|
| Phone is not turned on, no indicators | Short circuit, power controller burned | critical |
| The screen is working, but the touchscreen is not responding. | Oxidation of the display plume or digitizer | High-pitched |
| The speaker is snorting, the microphone is missing. | Water in the acoustic system (often treated with drying) | Low/Mediocre |
| Camera focuses with errors | Moisture in the camera module or contact oxidation | Medium. |
| Fast discharge and heating | Micro-circuiting on the board, current leakage | High-pitched |
Low hazard means the device is likely to work after thorough drying, and critical and high levels require specialist intervention using ultrasonic baths and microscopes.
💡
Even if the phone works normally after drying, corrosion processes can continue for months, gradually destroying the tracks on the board.
Professional cleaning and restoration
If self-care fails, or the phone falls into an aggressive fluid, the only way is through a service center, and the craftsmen perform a procedure known as ultrasound cleaning, and the device is placed in a special liquid that, when ultrasound is applied, knocks out the contaminants and oxides from under the chips.
Before cleaning, a visual examination is performed under a microscope, a technician looks for corrosion traces that look like green or white plaque on the contacts, replaces rotten elements, such as charging connectors, speakers or plumes, and in complex cases requires re-sweeping of the chips or restoration of the power chains.
Recovery costs depend on the extent of the damage, and replacing external modules (screen, battery) is cheaper than repairing the motherboard, but timely access to service greatly improves the chances of full data recovery and the operation of the device.
⚠️ Warning: Do not try to disassemble your smartphone yourself if it is under warranty.Falling seals and autopsy marks automatically void the manufacturer's warranty obligations, even if the breakdown is not water-related.

Prevention and protection in the future
After a successful rescue or purchase of a new device, you should consider preventive measures. Even if your Xiaomi is IP68 certified, this means protection only from clean water under certain conditions.
For active users, there are special sealers or underwater boxes that allow you to shoot videos underwater without risking electronics, and it is also a useful habit to regularly back up data to the cloud, which will not save the hardware, but will save important contacts and photos in the event of a fatal breakdown.
Remember that moisture protection degrades over time, with the glue dried up, the sealing gums worn out, and the old flagship with IP68 can sink into a glass of water faster than a new budgeter without certification.
💡
Regular backups to the Mi Cloud or Google Drive cloud service are the only 100% guarantee of your data security in case of any accidents.
