When a smartphone is in the water, it causes panic in any owner: whether it is a fall in the bathroom, pool or puddle, the count goes for minutes. For Xiaomi, Redmi and POCO devices, this is a critical moment that requires immediate and correct action.
Water itself is not as bad as the corrosion of contacts and short circuits that occur when you apply voltage to wet boards, which is why your first steps should be to completely shut down the gadget. Don't try to check whether the screen or sound is working.
The future of electronics depends on how quickly you remove the device from the moisture and whether you do the primary processing correctly. Even if you claim IP68 protection, it doesn't give you a 100% guarantee, especially if the device is not new. Consider a step-by-step rescue algorithm.
The first thing you need to do if you just pulled out a drowned machine is to turn it off immediately. Don't wait for it to go out or start glitching. Forced shutdown breaks the power chain and minimizes the risk of circuiting.
⚠️ Warning: It is strictly forbidden to connect a wet phone to a charger! this is guaranteed to cause the power controller and motherboard to burn.
If the device model allows, remove SIM-This will open additional holes for moisture to escape and save your data on the drive. Also remove the protective case, as the water under it lasts the longest.
After removing the trays, carefully examine the indicators of moisture protection (LCI). They are usually inside the slot for SIM-They're white or silver when they're dry, and when they come in contact with water, they turn red.
Now that the device is off, it needs to be as moisture-free as possible. Don't shake the phone violently, it can drive the droplets deeper into the case, into hard-to-reach areas of the motherboard.
Use dry, lilaless fabric or paper towels to thoroughly wipe all the outer surfaces. Pay special attention to the USB connectors, the speaker and the microphone. You can gently wet the holes, but don't stick cotton swabs too deep.
- 🧻 Carefully wet all external holes and joints of the body with a dry napkin.
- 💨 Gently blow water out of speakers (no saliva!), but don't use a hair dryer.
- 🔌 Remove the tray. SIM-Cards for better ventilation of internal cavities.
- 🚫 Do not turn on the phone to check the performance until full drying.
Many people mistakenly believe that drying with a hair dryer is a good solution, but the flow of hot air can melt the adhesive layer that seals the screen and damage the delicate plumes, and the hair dryer can drive moisture even deeper inside the device.
The best way to do this is to dry it naturally in a dry, warm place, and you can put your phone on a flat surface, preferably on a absorbent cloth, and you can point a fan (cold air) at it to make it more circulating, but don't heat the battery.
💡
Place the phone screen down on a soft towel so that water flows out of the connectors under the influence of gravity, but make sure that the pile of fabric does not clog the holes.
⚠️ Warning: Do not put your phone on hot heating batteries or under direct sunlight. Overheating of the lithium polymer battery can cause it to bloat or ignite.
There is a myth about the "saving" power of rice: in fact, rice dust can clog speakers and ports, and starch, when mixed with water, forms a sticky mass, and it is much more effective to use special moisture absorbers (silica gel), which are sold in construction stores.
If you do decide to use the "grandmother" method, it is better to wrap the phone in a thin cloth and then bury it in rice. But remember that the drying time should be at least 24-48 hours. The condensation inside the case should completely evaporate.
For more advanced users, there is a method with isopropyl alcohol (99%) that displaces water and evaporates quickly without causing corrosion. However, this method requires a complete disassembly of the phone and is only suitable for experienced toolmakers.
Why can't we use a hair dryer?
After enough time (at least a day, two is better), you can try turning on the device. If the Xiaomi phone is on and working normally, you're lucky, but even then, the risk of corrosion remains.
Watch the system closely, and if the screen starts to glitch, artifacts appear, the phone is warming up in downtime or discharges quickly, these are signs of contact oxidation, and then you can't wait.
We compare the main drying methods so you understand their effectiveness and risks:
| Method | Efficiency | Risks. | Time. |
|---|---|---|---|
| Rice (raw) | Low. | Dust, starch, long drying | 48+ hours |
| silicagel | Medium | Minimum | 24-48 hours |
| Fen (hot) | Dangerous. | Damage to glue, plumes, battery | Not recommended |
| Ultrasound (service) | Tall. | Demands a showdown. | 30-60 minutes. |
☑️ Post-drying check
If you notice problems after turning on, such as a sound or sensor is not working, try a software reset. Go to Settings → About Phone → MIUI version and check for updates that could fix controller errors, although this rarely helps with physical damage.
In the Redmi Note and Xiaomi Mi models, it is often the bottom board with a charging connector and a microphone that suffers, and if the phone is charging but you can't hear you, the problem is most likely oxidation of the microphone contacts, which can be cleaned with alcohol by disassembling the back cover.
However, if the phone doesn't turn on at all, don't try to rock the battery with multiple charging connections, which will finish off the power controller, in which case only professional diagnostics at the service center using a microscope and an ultrasound bath will help.
Services use electronic cleaning fluids to remove oxides. It's difficult to do this on your own, because you need to remove all the shielding plates and modules. Salt water causes corrosion 10 times faster than fresh water, so once you hit the sea, you need to immediately wash your phone with distilled water (if you can disassemble it) or immediately carry it to the service.
⚠️ Warranty from the manufacturer Xiaomi does not cover the ingress of moisture inside the case, even if there is a marking IP68. Moisture indicators will immediately show a violation of operating conditions.
💡
The most important step is time. The sooner you turn off your phone and start drying properly, the better the chances of saving the motherboard from irreversible corrosion.
Often users ask if it is possible to recover data if the phone is not turned on. If the problem is in the power controller or short circuit, the data on the flash memory can be intact.
Don't try to freeze your phone in the freezer. Condensate from the extreme temperature will kill the electronics, and the ice will crystallize and can physically damage the thin tracks on the board.
If your POCO or Xiaomi has survived a bath but then it quickly discharges, it may have been trapped in the power chain, in which case the phantom power consumption will eat up the charge even when it is off.
So to sum up, a drowned phone is always a lottery, but doing the right thing increases your chances of winning, and the key is not to panic, turn off the device, keep it from charging and dry naturally, or call the professionals to clean it with ultrasound.
