Water and electronics are the worst enemies, but it's not time to panic. If your Xiaomi is suddenly in a puddle, toilet or even a pool, the first 30 seconds decide everything. The actions at that point determine whether the phone will remain functional or turn into a brick. It's important to understand that even if the smartphone does not turn off immediately, it does not mean that it is safe - corrosion begins unnoticed, and the consequences will manifest in days or weeks.
Modern Xiaomi models (such as Xiaomi 13 Ultra or Redmi Note 12 Pro+) have IP53/IP68 protection, but this is not a guarantee of survival. The manufacturer tests the devices in fresh water without impurities - sea water, sugary drinks or soap solution kill the phone many times faster. Even if the moisture indicator inside the connector has not changed, this does not mean that moisture has not penetratedified the screen or the board.
This article provides a concrete plan of action based on Xiaomi service centers and instructions, without the myths of rice and hairdryer, which often make things worse, and what to do if the phone is no longer on, and how to minimize damage if the device is not saved.
Step 1: Remove your phone from the water immediately β but DO NOT press the buttons!
The first instinct is to pull Xiaomi out and check if it works. This is the most common mistake. When you come into contact with water, you short circuit, and every push of a button (Power, Volume) or try to turn on the screen accelerates the corrosion of contacts.
What to do:
- Carefully remove the phone from the water in one motion (do not shake, do not shake - so moisture deeper penetrates into the interior).
- If the device was in the case, remove it immediately. The case retains moisture and creates a "greenhouse effect".
- Put the smartphone on a flat dry surface with the screen up (so that the water is not glass under the display).
Critically, if your phone is already off, DO NOT try to turn it on. If it's on, do not force it to turn it off (wait for the battery to run out if it's safe).
Step 2: Turn off power β but not in the way you think
Many people advise to βtake out the battery,β but in modern Xiaomi (except for rare models like the POCO M2), the battery is not removable. Attempting to open the case without tools will damage the plumes or antennas.
β If the phone's on:
- π Transfer to flight mode (to disable data transmission and reduce the load on the board).
- π Disable all wireless modules: Wi-Fi, Bluetooth, NFC.
- π΄ Donβt plug in the charger β itβs guaranteed to kill the phone.
β If the phone's off:
- π« Don't turn it on, even if you really want to check it out.
- π Disconnect all cables (Type-C, headphones).
Warning: If the phone has been in salt water (sea, sweat), wash it with distilled water (not from the tap!) for 10 seconds.

Step 3: Drying β Why Rice and Dryer Are Dangerous
The myth of rice has been around for decades, but it's actually bad, and rice grains don't absorb moisture efficiently, but their dust and starch get into connectors and ports, making the problem worse, and hair dryer is not an option either, because hot air can melt protective pads or damage the screen.
β Proper drying:
- Wet the moisture with paper towels or napkins (don't rub!). Pay attention: π± Type-C connector (use a toothpick wrapped with a napkin). π Speakers and microphone (do not poke deeply!). π Slot SIM/SD (Take out the tray and dry separately).
Place your phone in a dry place

Don't turn on 24-48 hours.

β οΈ Attention: If after drying on the screen appeared divorces, spots or backlighting is uneven - this is a sign of moisture getting under the display. In this case, do not turn on the phone and contact the service: self-drying can lead to detachment of the touch screen.

Step 4: Diagnosis after drying β when to include
48 hours later, you're ready to check the phone. Take your time.
- π Visible corrosion on connectors (green or white plaque).
- π§ Drop under the screen (visible when the backlight is turned on).
- π Battery bloating (screen or back cover move away from the body).
If nothing suspicious, connect your phone to the original charger (not wireless charging!).Don't turn it on right away - look at the charging indicator:
- β‘ If the red/orange light goes on, the phone is alive but dead. Wait 10-15% before turning on.
- β If the indicator doesn't burn or flashes unusually, the board is damaged!
If the phone is on:
- Check the sensor (does not "float" the presses).
- Test the camera, the speakers, the microphone.
- Connect the headphones - if the sound is distorted, moisture remains in the connector.
π‘
If the phone is turned on, but quickly discharges or overheats, this is a sign of damage to the battery. Immediately back up the data and take the device to the service: lithium-ion batteries can ignite.
Step 5: If the phone doesnβt turn on, what to do next
If Xiaomi is not showing any signs of life after drying, don't panic.
| Symptoms. | Possible cause | Decision |
|---|---|---|
| The charging indicator is not on. | Short circuit on board or damaged power controller | Diagnostics are required in the service (cost from 1500) β½) |
| The phone vibrates, but the screen is black. | Detachment of the display plume or damage to the graphics chip | Reflashing or replacing the screen (from 3000) β½) |
| The Mi logo lights up, then turns off. | Bootloader or flash memory damaged | Firmware through EDL-Regime (authorized service required) |
| Phone warms up when charging | Short circuit in the battery | Battery replacement (from 2000) β½) + check-up |

β οΈ Note: If the phone doesn't turn on and respond to charging, DO NOT try to disassemble it yourself.Modern Xiaomi have a glued body, and when opened without a special tool, you risk damaging it: πΆ Antenna plumes (net loss). π Flexible battery contacts (fire risk). π₯οΈ Screen (detachment) OLED-The disassembly service uses infrared stations and ultrasonic cleaning, which are not available at home.
What you should not do under any circumstances
Some of the "advice" on the Internet is not just useless, it destroys the phone completely.
β Freeze the phone.
- βοΈ Ice does not βfreezeβ moisture β it destroys chips due to condensation during defrosting.
β Use a vacuum cleaner
- π The airflow drives moisture deeper into the body and can tear off small details.
β Dry on a battery or under direct sunlight
- βοΈ Overheating warps the board and the screen. The optimal drying temperature is 20-25.Β°C.
β Try to turn on the phone "check for a second"
- π Even a short-term inclusion with moisture inside leads to electrolytic corrosion - the slow destruction of tracks on the board.
β Use alcohol or liquids for cleaning
- π§΄ Alcohol dissolves protective coatings on the board. Services use special solutions (for example, Contact Cleaner) to clean the board).
π‘
If the water has been injected for more than 72 hours and the phone is working normally, it doesn't mean it's "dried up," it can show up in weeks or months. To avoid surprises, make a diagnosis on the service (cost). ~1000 β½).
Service vs. self-repair: what to choose
If the phone doesn't turn on or malfunctions, you have a choice: carry it to the service or try to fix it yourself.
π§ When can I try to repair it myself:
- π± The phone is turned on but not running a single module (e.g. speaker or camera).
- π§ Moisture only got into the Type-C connector or tray SIM.
- π οΈ You have experience disassembling equipment and tools (suction cup, plastic blades, Torx screwdrivers). T3/T4).
π₯ When you must contact the service:
- π₯ Phone warms, smells of smoke or swelled battery.
- π₯οΈ On the screen, artifacts (strips, flickering) are a sign of damage to the graphics chip.
- π΅ No network or IMEI dropped on 0000... (an antenna or communication module damaged).
- πΈ Phone for warranty (self-repair cancels it).
π° Cost of repair in the service (example prices for Xiaomi):
- π‘ Repair of the antenna module: 1000β3000 β½.
π‘ Tip: If your phone is older than 2-3 years, compare the cost of repairs to the price of a new device. For example, repairing a Redmi Note 9 after water can cost 70-80% of the cost of a new smartphone.
