When your Xiaomi is suddenly in the water, it causes panic in any owner.Whether it is a fall in the bath, pool or just a puddle on the street, the speed and correctness of your actions in the first minutes directly affect the chances of bringing the gadget back to life. Many users make critical mistakes trying to turn the device on or charge it right away, which often leads to irreversible short circuit.
Unlike older models, the modern Redmi and POCO smartphones often have splash protection, but that doesn't make them waterproof.Water is highly penetrating and can get in through a dynamic conversational speaker, charging connector or microphone.The corrosion of metal contacts starts instantly, and if this process is not stopped, after a few days or even weeks the board can fail.
In this guide, we will discuss an emergency algorithm that will help minimize damage, you will learn why you can not use a hair dryer or rice, how to properly disassemble the case for drying, and in which cases you will need professional cleaning in an ultrasonic bath, the main thing is to keep your cool and follow the instructions clearly.
⚠️ Warning: If the smartphone falls into salty sea water or liquid with sugar (soda, juice), the risk of death of the device increases many times.
First steps: the algorithm of emergency assistance
The first thing you need to do when you see a floating phone or pull it out of a puddle is to immediately remove it from the liquid. Don't try to look for the shutdown button while the device is in water. Every second you have the gadget on in an aggressive environment increases the likelihood of a short circuit.
Once you have the device in your hands, quickly assess its condition. If the screen is on, turn it off immediately. For non-removable battery models, which are the vast majority of modern Xiaomi, (holding) power buttons is the only way to interrupt the power supply to the board. In some cases, if the sensor does not respond due to water, you may need to press the power and volume buttons simultaneously.
- 🚫 Do not push the buttons randomly - this can push water deeper inside the enclosure through the gaps.
- 🔌 Turn off the charging cable immediately if it was connected at the time of the fall.
- 📱 Remove the protective cover, as it retains moisture and prevents evaporation.
- 💿 Remove the tray. SIM-Maps and memory card to open air access.
After extraction SIM-Look closely at the humidity indicators on Xiaomi smartphones, which are often located inside the SIM tray or next to the charging connector, initially white or silver, but when in contact with water, they turn red or pink. This is an important marker for the service center, indicating a violation of operating conditions.
What you can’t do with a wet Xiaomi
There are many myths about "people's" methods of saving electronics that actually do more harm than good, the most common being the use of rice. The grain does absorb moisture, but it does so slowly, and the fine rice dust clogs the connectors, speakers and microphones, creating porridge inside the device.
Another dangerous mistake is using a hair dryer or heating on a battery. High temperatures destroy the adhesive layer that seals the case and can damage the lithium polymer battery by causing it to bloat. In addition, the flow of hot air drives water droplets deeper into hard-to-reach circuit board locations, distributing moisture throughout the chip surface.
⚠️ Warning: It is strictly forbidden to connect a wet smartphone to a charger "for check" and to apply the voltage to a wet board is guaranteed to cause the power controller or other expensive components to burn.
Also, you should not shake the phone too hard, sudden movements can spray the liquid inside the board, increasing the area of the lesion, and careful dipping movements with soft tissue will be enough to remove external droplets.

The process of proper drying of the device
Drying properly is a long process that requires patience. Once you've turned off your phone and removed all the excess, put it on a flat horizontal surface, and it's advisable to use a surface covered with a paper towel or a soft cloth that absorbs moisture well.
Silicagel can be used to effectively remove moisture from the interior, and you can use silica gel (beads that are put in shoe boxes). Put your phone and silica gel bags in a sealed container. Silica gel works much more efficiently than rice and does not leave dust. However, remember that this method only helps with little moisture and high humidity inside the case.
- 🌬️ Ensure good air circulation in the room, but avoid direct drafts.
- ☀️ Do not leave your phone in direct sunlight – overheating is dangerous.
- 📺 Put the device down for at least 24 to 48 hours without trying to turn it on.
- 🔄 Change the position of the phone periodically so that water can evaporate from different holes.
If you have access to a cold air compressor (like a keyboard cleaner), you can gently blow the connectors, hold the can straight up to keep the condensation out, and blow in short bursts, which will help drive large droplets of water out of the speakers and ports.
☑️ Checklist of primary processing
Specificity of Xiaomi, Redmi and POCO models
The devices in different lines have design features. Xiaomi’s flagship models (Mi and Xiaomi Number series) often feature sealing pads and have an IP68 protection rating, meaning they can withstand a brief dive, but over time the glue dries up and the tightness is broken.
Redmi and POCO models are often low-cost, lacking rubber seals around volume buttons and charging sockets, and are almost unimpeded, requiring more thorough and prolonged drying and often disassembly.
And we need to focus on dynamic dynamics, which is often combined with conversational dynamics in modern Xiaomi models, and if the sound becomes quiet or hoarse after drying, it means that there is moisture inside or corrosion of the membrane, and in some cases, it helps to play low-frequency sound at maximum volume, but you can only do this after you have confidence in the dryness of the contacts.
| Model/Series | IP protection | Risk in falling | Recommendation |
|---|---|---|---|
| Xiaomi 13 / 14 Pro | IP68 | Medium (depending on the wear of glue) | Drying 24 hours, checking the speakers |
| Redmi Note 12/13 | IP53 (spray) | High-pitched | Urgent drying, possible disassembly |
| POCO X/F series | No. IP53 | critical | Do not include 48 hours, cleaning the fee |
| Xiaomi Mi Mix | Partial | High (due to construction) | Careful drying without heating |
💡
The presence of IP68 does not give a lifetime guarantee against water, as the tightness decreases over time due to temperature changes and shocks.
Diagnosis after drying: turn on and check
Two days later, you're ready to check the results. Turn on the device only if you're sure it's completely dry. The first sign of a problem is the behavior of the charging indicator. If the phone is responding to the cable connection, but the screen is black, maybe the power controller or the display itself has burned.
And if you look at the behavior of the system, if the phone is turned on, but it discharges quickly, it warms up in the camera area, or it reboots spontaneously, it leaves an oxidized contact inside, and the oxidation creates a parasitic resistance that disrupts the normal electronics.
Check all the functions: sensor, microphone, speakers, vibration and cameras. Often water enters the camera module, causing the lenses to fog from the inside. If you see condensation under the camera glass, you need to continue drying or contact the wizard to open the module.
⚠️ Attention: The appearance of green or white spots on the screen, as well as “dead” areas of the touch screen indicate damage to the plume of the display or the matrix itself by the liquid.
When professional cleaning is necessary
Home methods are only effective when moisture is easily ingested. If the phone has been in the water completely, has fallen into the toilet or the sea, you can't do without opening and cleaning the board. In the service center, the device is dismantled, the battery is disconnected and the board is placed in an ultrasonic bath with a special solution.
Ultrasound knocks tiny drops of water and salt out of the chips, which you can't reach by hand, and then you put a protective varnish on the contacts, and if you notice that the charging connector is blackened or you see a green plaque on the board, doing it yourself can only make things worse.
The cost of cleaning the service is usually much lower than replacing the burned motherboard. So if the phone is not behaving properly after drying, it is better not to take risks and leave it to the professionals, especially for expensive flagship models with complex board architecture.
💡
Even if the phone is working normally after being in the water, back up your data to the Xiaomi Cloud or your computer. corrosion can occur in a month and you risk losing important photos and contacts.
