When a smartphone is suddenly in the water, it causes panic in any owner, and the device brand Xiaomi is no exception. Instant reaction in the first minutes and even seconds often determines whether the gadget will work after drying or it will need a complex and expensive repair in the service center. Water, especially salty or containing impurities (as in the pool or the sea), is an electrolyte that causes an instant short circuit on the board.
It is important to understand that even if the device is equipped with IP68 protection, this does not give a 100% guarantee of survival when diving, especially if the device is more than a year old or has been mechanically damaged by the body. Statistics show that most users make fatal mistakes in the first hour after the incident, trying to “revive” the device with the wrong methods, which only exacerbates the corrosion of internal components.
Next, we will look at a detailed algorithm of actions that will help minimize damage and possibly save your Xiaomi model from complete failure.
First steps: retracting and disconnecting
The first thing you need to do if you've just pulled a drowned phone out of the water is to remove it immediately and turn it off. If the screen is still responding, don't try to flip through the menu or check the apps, your only goal is to interrupt the power supply to the motherboard. In the case of a sensor that is not working because of water, press the power button for 10-15 seconds to force a reboot or completely turn it off.
⚠️ Attention: It is strictly forbidden to put a recessed smartphone on charging or connect it to a computer through USB-Attempting to apply voltage to a wet circuit board is guaranteed to short circuit and burn the power controller.
After the shutdown, you need to immediately remove the tray for SIM-Opening the tray also helps to slightly break the tightness of the case, allowing water to evaporate more actively, although the main purpose here is to save your personal data and contacts stored on the SIM card.
- 🚫 Don’t push random buttons to check if your phone is working.
- 💧 Shake the water gently, but don’t shake the device too hard so that moisture doesn’t penetrate deeper.
- 🔋 If your Xiaomi model has a removable battery (in older models), remove it immediately.
- 🧻 Wash the case with a dry napkin or towel, paying attention to ports and speakers.
Many people forget about covers that often hold water to the case, creating a compress effect. Remove the protective cover, protective glass and any stickers to ensure maximum air access to the surfaces of the device.
What to do categorically can not be done
There are many myths online about how to save electronics after contact with liquids, and following them often does more harm than water itself. The most common and dangerous myth is using a dryer. Hot air can not only melt the glue that holds the display and body together, but it will drive moisture droplets even deeper into the device, distributing them throughout the motherboard.
Also wrong is the idea that the phone should be put in rice. Rice cereals do have absorbent properties, but it creates fine dust that clogs connectors, speakers and microphones Redmi or Mi. In addition, the rice dries too slowly, and before it pulls out the water, corrosion has already done its job. Starch dust, mixing with water, forms a sticky mass, which then is very difficult to clean.
- 🌬️ Do not use a dryer, even in cold air mode, as the flow can drive the water deeper.
- 🍚 Do not put your phone in rice, seclusion or other bulk products.
- 🔋 Do not try to turn on the device "just check" until it is completely dry.
- 🌀 Don’t shake your phone dramatically while trying to pour water out of the speakers.
Another critical mistake is using compressed air from cans, and a powerful jet can damage the delicate components inside the body or damage the moisture membranes if they survive, and your job is to let the moisture come out naturally or to dry the device with gentle methods, which will be discussed below.
Why is rice inefficient?
The process of proper drying of the device
Once you've eliminated all the harmful effects, you start the passive drying phase, and the ideal place to put a wet gadget is a dry, well-ventilated space at room temperature, and you can put your phone on a dry towel with a screen up or down, periodically turning over so that moisture comes out of the different holes.
To speed up the process, you can use silica gel, if you have enough of it, put your phone and silica gel bags in a sealed container, and silica gel is a great adsorbent, and it can pull moisture out of ports more efficiently than just air, but remember that this process takes time.
| Drying method | Efficiency | Risks. | Time. |
|---|---|---|---|
| Open air | Medium | Dust | 24-48 hours |
| silicagel | Tall. | No. | 12-24 hour |
| Rice (grain) | Low. | Dust, starch | 48+ hours |
| Fen/Warm | Dangerous. | Overheating, moisture inside | Not applicable. |
The optimal drying time is 24 to 48 hours. Don't try to shorten that time. If you turn on your phone early, moisture residues can cause a short circuit. Even if after 24 hours the phone turned on, it doesn't mean that the inside has become dry - water could have remained in hard-to-reach places under metal screens.
☑️ Drying action plan
Cleaning for salts and corrosion
If your Xiaomi phone has been in salty seawater or water from a chlorinated pool, simply drying it may not help. Salts and chlorine, drying, form crystals that continue to destroy contacts and cause corrosion even after turning on. In such cases, professionals recommend washing the board, but at home it is risky.
To minimize the effects of aggressive fluid, you can gently wipe the available ports (USB, headphone jack) with a cotton swab slightly soaked in isopropyl alcohol (at least 90%). Alcohol displaces water and quickly evaporates, leaving no traces. However, pouring alcohol into the case or pouring it into the connectors is not necessary without disassembly skills.
⚠️ Attention: Isopropyl alcohol can damage the oleophobic screen covering and some plastic elements if you use a low concentration solution or rub too much. Use the method only for metal port contacts.
The most reliable way to save seawater is to immediately deliver it to a service center, where the device will be opened, the battery will be turned off and the board is washed in an ultrasonic bath with a special solution, which is the only way to guarantee the removal of salt plaque.
💡
Use only high-purification isopropyl alcohol (isopropanol). Conventional ethyl alcohol or vodka contains water and will only make the situation worse by adding even more moisture and impurities.
Diagnosis after drying
48 hours later, you decided to turn on the device, and the first sign of success is the Mi or Redmi logo. If the phone is on, don't be too excited. Check the touchscreen, microphone, speakers, cameras and communication modules carefully.
Often, water damages not the board itself, but plumes or individual modules, for example, a vibration or proximity sensor may stop working (LCI), squat SIM-If they turn red, the warranty on the device is likely to burn out, even if the phone is working.
- 📱 Check the operation of the touch screen throughout the area.
- 🔊 Listen to the sound through the speaker and headphones.
- 📸 Take a test photo and video to check the cameras.
- 📶 Make sure the network is stable and the Wi-Fi is running.
If the phone turns on but quickly discharges or warms up in downtime, it is a sure sign of oxidation of the power chain or short circuit in one of the components, in which case the operation of the device is dangerous - it can swell or catch fire.
💡
Even if the phone is working after drying, the risk of corrosion persists, and oxidation can occur in a week or a month, so monitoring the condition of the device is mandatory.
When professional repairs are needed
There are a number of symptoms that make it useless to do it on your own and require the intervention of engineers, and if the phone doesn't turn on at all, the charging light goes on, but the screen is black, or the device is cyclically restarted, a serious problem, and the water probably got to the processor or the power controller.
Also, the reason for contacting the service is the entry of liquid into the camera. If you see droplets or a fog under the camera glass that does not disappear after a day, then the sealability of the module is broken, further operation will lead to corrosion of the matrix contacts and the inability to take a high-quality picture.
Replacement of connectors or board cleaning costs less than replacing the motherboard or display. In the case of modern Xiaomi models, where many components are soldered on a single board, repair may not be economically feasible.
