When your smartphone is suddenly in the water, it causes panic in any owner. Whether it is a fall in the sink, toilet or river while walking, the first seconds decide the fate of the device. For owners of Xiaomi, Redmi and Poco, it is important to act instantly, because water conducts electricity and quickly disables the chips.
In this article, we will discuss a detailed algorithm of actions that will help minimize damage and possibly save your gadget from complete destruction. It is important to understand that even having an IP68 waterproof certificate does not give a 100% guarantee, especially if the phone is old or has been hit.
Don't waste time reading long introductions -- it's minutes. The faster you remove the device from the liquid, the better the chances of a successful recovery without expensive repairs at the service center.
⚠️ Warning: If the phone falls into salt water or an aggressive liquid (juice, soda), the risk of corrosion increases many times. In such cases, fresh water washing is mandatory, but only after a complete power outage, if possible.
Primary Actions: Removal and Disconnection
The first thing you need to do when you see a spike is to immediately pull the phone out of the water. Don't try to check if the screen or the sound is working while the device is in the liquid. Every second you're in the water increases the likelihood of a short circuit.
Once you have the gadget in your hands, press and hold the power button immediately to force it to turn it off. If the screen does not respond to touches due to water, use a physical button.
Immediately after turning off, remove the protective case. Cases, especially silicone ones, can trap moisture from the case, creating a greenhouse effect and slowing evaporation. SIM-cards and memory card, if installed.
- 📱 Remove the device from the liquid immediately.
- 🔌 Forced to turn off the smartphone, without waiting for the completion of the program.
- 🔋 Remove the case and pull out the SIM card tray for air access.
- 🚫 Do not try to charge your phone or connect it to your computer.
☑️ Emergency action checklist
What is absolutely impossible to do
There are a lot of bad advice online that will finish off your Xiaomi instead of helping you. The most popular myth is the use of a hair dryer. Hot air can melt the adhesive seams of the case, damage the display, or drive moisture even deeper into the device under jet pressure.
The second common advice is to put your phone in rice. Rice grains do absorb moisture, but they do so slowly and create a lot of fine dust. This dust can clog charging connectors, microphones and speakers, creating a new problem instead of solving the old one.
Also, don't shake your phone too much. Abrupt movements can blow water droplets into the interior where they weren't originally there, and your job is to let the moisture come out of your own pocket or to gently remove it from the surface.
⚠️ Warning: Never connect a wet phone to a “check-in” charger, guaranteed to burn the power controller or the entire motherboard.
Why is rice a bad idea?
The process of proper drying of the smartphone
Once you've done the initial steps, the drying phase begins, and you put your phone on a dry towel or a paper napkin in a horizontal position, and you'd better place it in a well-ventilated place, but not in direct sunlight.
To speed up the process, you can use a fan by directing the flow of cold air to the exposed parts of the housing (connectors, speakers), which will help evaporate moisture without overheating the components. The process of natural drying can take from 24 to 48 hours.
If you have a bag of silica gel (beads that are put in shoe boxes), put the phone in a sealed container with them. Silica gel absorbs moisture from the air much more efficiently than rice and leaves no dust.
💡
Use a few silica gel bags strewn around your phone in a container to create a low-humidity zone, which will speed up the pulling of moisture from the pores of the case.
Comparison of drying methods: efficiency and risks
Different methods have different effectiveness. It's important to understand that no home method guarantees complete removal of moisture from hard-to-reach areas under the screen or chips. Below is a table comparing popular methods.
| Method | Efficiency | Risks. | Time. |
|---|---|---|---|
| Natural drying | Medium | Minimum | 24-48 hours |
| silicagel | Tall. | Low. | 12-24 hour |
| Fen (hot) | Low. | High (glue damage, overheating) | 10-20 minutes |
| Rhys | Low. | Medium (dust in connectors) | 24+ hour |
As you can see from the table, the safest option is time and silica gel, and aggressive methods like heating often cause the phone to turn on, but dies a week later due to corrosion.
💡
The safest and most effective way to dry is to stay in a low-humidity environment (silica gel) for a long time without heating.
Post-drying diagnosis
After at least 24 hours (preferably 48), you can try turning on the device. Connect the charging cable and see the indicator reaction. If the phone starts charging, that's a good sign, but not the end.
If you look carefully at the camera, if you see condensation inside the lenses, it means that the moisture is still inside, and then you can't continue operating, the steam will circulate inside and oxidize the contacts. Repeat the drying procedure.
Check the speakers and the microphone. Often after water, the sound becomes quiet or hoarse. Some Xiaomi models have a software way to push water with a sound wave, but you can only use it by making sure that the device is completely dry on the outside.
- 🔍 Check the camera lenses for condensation.
- 🔊 Check the sound through the speaker and headphones.
- 📶 Make sure Wi-Fi and Bluetooth are stable (antennas are sensitive to oxidation).
- 🔋 Watch the battery discharge rate – a sharp drop in capacity indicates problems.
Signs of oxidation and the need for repair
Even if the phone is running, the danger is still there, and the water, especially the tap water, has salts and minerals, and once it's drying, it stays on the board and starts to corrode the metal, and it can take weeks.
Notice the appearance of strange artifacts on the screen, spontaneous reboots or heating of the case in the area of the processor, these symptoms indicate that corrosion has reached important nodes.
In this case, professional cleaning in the ultrasonic bath using special reagents is necessary. It is impossible to wash salts from under the chips with home remedies.
⚠️ Warning: If you see white or greenish plaque on the motherboard, it's oxidation products, and if you run the device in this state, you'll have a complete failure.
Prevention and protection in the future
To avoid a repeat of this, consider additional protection, and Xiaomi owners who often visit the water or work in difficult conditions, there are special sealed cases.
It is also helpful (once a year) to check the condition of the sealing rubber bands if your phone model is moisture-protected, and over time the glue dries out and the leakage is broken, even if the phone is intact.
Regularly back up your data to the Mi Cloud or your computer, and if you fall into the water, you'll only lose iron, but you'll save important photos and contacts.
