When your Xiaomi is in the water, it causes instant panic in any owner. The smartphone can fall into the sink, fall in heavy rain or completely plunge into the bathroom. At this point, the count goes literally for seconds, because the corrosion of metal contacts begins immediately after moisture enters the case.
Modern models of the brand, such as Xiaomi 13 or Xiaomi 14, often have IP68 protection, which implies the theoretical possibility of survival when diving. However, budget and mid-budget devices of the Redmi and Poco series are deprived of such protection or have only basic moisture protection from splashes. Even if the phone is turned on and works immediately after an incident, this does not guarantee the absence of internal damage.
The main task of the owner in the first minutes is to prevent the device from turning on and limit the spread of fluid inside the board as much as possible. Oxidation can lead to a short circuit that will disable the power controller or processor. Below is a detailed strategy of behavior that will help minimize damage and possibly save the gadget from complete death.
First Actions: Algorithm of Salvation
Once you've got your phone out of the water, the first thing you need to do is turn it off immediately. If the screen goes out on its own, do not try to turn it on to "check if it works." Any current on the wet board is guaranteed to short circuit.
The second step is to extract all the foreign elements. SIM-This will not only remove moisture from the slots, but also allow air to circulate inside the case through the holes formed.If your Xiaomi has a removable battery (which is rare for new models), it also needs to be removed.
⚠️ Warning: Don’t shake your phone sharply or try to blow water out of the connectors with your mouth.You risk driving the droplets of moisture deeper into the case, where they will settle on critical components such as display plumes or camera connectors.
After removing the trays, gently wipe the body with a soft, well-absorbent cloth or paper towels. Pay special attention to the area around the volume and on buttons, as well as the charging connector. It is important to remove all visible moisture from the surface so that it does not clog back in with further manipulation.
☑️ Emergency checklist
What is absolutely impossible to do
There are many myths on the Internet about how to save a wet phone, and following these tips often does more harm than water itself, like using a dryer to dry is one of the most common mistakes. Hot air can melt the glue that holds the display and damage it. OLED-matrix.
Another dangerous myth is the use of rice: grain dust, which is formed when a phone comes into contact with cereals, can clog the speaker and connectors, creating an abrasive mixture with moisture, and rice dries too slowly and does not have sufficient hygroscopic properties to save electronics.
- 🚫 Do not connect your phone to the charger until you have made sure that all contacts are completely dry.
- 🚫 Do not use open fire sources or heating appliances (batteries, ovens) to speed up drying.
- 🚫 Do not try to disassemble the phone yourself if you have no experience as you may damage fragile plumes.
Also avoid high-pressure compressed air. Air jets can mechanically damage microphones or tear small components off the board. Vibration and sudden movements are also contraindicated, as they help move moisture to hard-to-reach corners of the device.
💡
If the phone falls into salty sea water, it is advisable to quickly (carefully!) rinse it with fresh distilled water before drying to wash away the salt that causes the most aggressive corrosion.
Proper drying: methods and means
After the initial steps are taken, you need to dry properly, and the best way to do this is to put the device in a dry, warm, well-ventilated place, and direct sunlight is not acceptable, because it can overheat the battery and cause it to swell.
To absorb moisture from the air around the phone, it is best to use special moisture absorbers such as silica gel (beads that are often put in shoe boxes). Place the phone and silica gel bags in a sealed container, which will create a low-humidity environment that will "pull" water out of the device.
| Drying method | Efficiency | Risks. | Recommended time |
|---|---|---|---|
| silicagel | Tall. | Minimum | 24-48 hours |
| Rice (raw) | Low. | Dust in the connectors | 48+ hours |
| Fen (cold) | Medium | A corral deeper | Not recommended |
| UV dryer | Medium | Plastic overheating | 2-4 hours |
If you don't have silica gel on hand, you can use a cat litter based on Bentonite clay, which also absorbs moisture very well, and the main thing is to ensure that the air around the phone is in close contact with the dehumidifier, but not to completely fall asleep, so that the dust does not get inside through the speaker.
Post-drying diagnosis
After the phone has been in the dehumidifier for at least 24 hours (preferably 48), you can try to turn it on. The first sign of a problem may be the behavior of the charging indicator. Connect the cable and see if the screen or LED is reacting. If the phone vibrates but the screen is black, this may indicate a malfunction of the display or plume.
Check the touch screen. Water often causes "fanomic" taps or a touchscreen failure to work in certain areas. It is also worth testing the speakers and microphone: when water hits, the sound can become hoarse or quiet. In some cases, Xiaomi has a speaker cleaning feature that can be activated through special codes or applications.
⚠️ Warning: If you turn on the phone makes strange sounds, smells of burning or it begins to heat up in the area of the camera, immediately turn it off.
Pay attention to the indicators of water protection (LCI), If they are available on your device (usually in the tray) SIM-If the white circle turns red, then contact with water has been recorded, and if you contact the service under the guarantee, you will likely be denied free repairs.
Software Tests and Hidden Problems
If the phone is on and seems to be working, don't be too excited. Water may have damaged not only visible components, but also caused hidden corrosion on the board. There's an engineering menu to check functionality in the MIUI or HyperOS shell. To get there, type ##6484## in the ringer.
In the engineering menu, select Version or Single-item Test, where you can consistently check all modules: vibration, screen, buttons, cameras, proximity and light sensors. Pay special attention to the proximity sensor, as it often fails when it comes into contact with moisture, which causes the screen to go out during a conversation.
- 📱 Check Wi-Fi and Bluetooth: antenna modules are sensitive to contact oxidation.
- 📱 Camera test: Take a photo of a white sheet to see spots or blur caused by moisture under the lens.
- 📱 Verification GPS: The navigation module may also be affected by moisture.
What to do if the phone is turned on, but discharges quickly?
When professional repairs are needed
There are a number of symptoms in which self-treatment is useless and requires the intervention of specialists. If the phone does not turn on at all, even after a long drying and checking the charger, the power controller or charging circuit is most likely burned.
Corrosion is a devious enemy, and it can occur a week or a month after an incident where oxides eat up the board tracks, so if the phone has been in water, even if it works, it is recommended that you do a preventive cleaning in the service center using an ultrasound bath and special chemicals.
The cost of repair depends on the extent of the damage. Replacing the charging connector or cleaning the board is cheaper than replacing the motherboard or display. In some cases, it is more cost-effective to buy a new smartphone, especially if it is the older Redmi or Poco models.
💡
Even if the phone is working after being hit by water, the risk of the device suddenly dying due to corrosion remains high for several months.
Prevention and protection in the future
To minimize future risks, consider additional protection, there are special sealed underwater camera packages that allow you to use your smartphone even in the pool, and for everyday wear, you should choose high-sided covers that protect the screen and camera.
There are also hydrophobic sprays that create a water-repellent film on the surface of the phone, which won't save you from a full dive, but can buy you valuable time if your phone accidentally falls into a puddle or sink, but remember that no coating gives you 100% guarantee.
Regularly back up important data to the Mi Cloud or your computer, photos, contacts and documents are more important than the device itself, and in the event of a fatal hardware outcome, you will retain your memories and information.
