Did you take Xiaomi out of your pocket or bag and find that the charging connector got water? The phone is not charging, and the screen may be on a moisture warning or nothing happens? This situation is familiar to many — especially smartphone owners without official IP68 protection. Even if your model has spray protection (Redmi Note 12 Pro+, Xiaomi 13 Ultra), prolonged contact with water or liquid under pressure (for example, in the shower) can disable charging contacts.
The key is not to panic or try to connect your phone to the charger immediately. The first minutes after water hits are critical: the wrong actions can lead to short circuit, damage to the motherboard or complete failure of the battery. In this article, we will discuss what to do immediately, how to dry your smartphone correctly, and when to contact the service center. And also explain why some “folk” methods (such as drying with a hair dryer or rice) can only make things worse.
First steps: what to do immediately after water hits
If you notice water in the USB-C or Micro-USB connector (in older Xiaomi models), follow the algorithm:
- 🔌 Disconnect your phone immediately from charging if it's been connected. Even if it's not charging, the risk of short circuits remains.
- 📴 Turn off your smartphone (if it still works). To do this, press the power button and select "Switch off." If the phone doesn't respond, press the power button. + Volume increase by 10-15 seconds for forced reboot.
- 🔍 Get it. SIM-card and memory card (if any) water could leak under the tray, which increases the risk of contact corrosion.
- 🚫 Don’t shake the phone or blow into the connector – this can drive water deeper inside the case.
If the warning “Moisture detected in the charging connector” (typical for MIUI 12-14) appears on the screen, it means that the humidity sensors are activated, in which case the phone blocks charging until it completely drys out, and do not try to trick the system by connecting to another cable or charger, this can damage the power controller.
What not to do: dangerous "advice" from the Internet
The web is full of recommendations that not only do not help, but can finally kill the phone.
- 🔥 Dry with a hair dryer. Hot air can melt the safety pads inside the connector, and also damage the chips.
- 🍚 Bury it in rice. Rice absorbs moisture very slowly, and its dust can get into the connector and make the problem worse.
- 🔌 Just in case, just in case, even if the phone turns on, the moisture inside the connector can cause the contacts to oxidize.
- 🧊 Put it in the freezer, and the temperature drops cause condensation inside the body.
⚠️ Warning: If after water hits, the phone starts to warm up, make unusual sounds (squeaking, crackling) or smells of arrow - immediately turn it off and do not turn it on before visiting the service!
Also, don't use alcohol or acetone to clean the connector, which can dissolve the contact coating and damage plastic parts, and if you want to dry faster, you might want to use silica gel -- which absorbs moisture 10 times more efficiently than rice.
How to Dry Xiaomi Phone After Water Infection
The best way to dry is to naturally evaporate moisture in a well-ventilated place. Here's a step-by-step guide:
- Wet the visible moisture with a napkin or toilet paper. Don't push too hard, just light bloating movements.
- Place the phone vertically (downward connector) so that the water drains away under gravity, and you can lean against the wall or put it on a stand.
- Use a fan (not a hairdryer!) at minimum speed. Direct the air flow not into the connector, but along the body to speed up evaporation.
- Leave it for 24 to 48 hours. Yes, it's long, but that's the only way to guarantee complete drying, and moisture can stay under the screen or on the motherboard.
For Xiaomi models with a fixed battery (most modern smartphones), drying should be especially thorough. If you are technically versed, you can carefully remove the back cover (at your own risk!) and dry the insides, but it requires special tools (suction cup, mediator, T3/T4 screwdriver and experience.

How to check if the charging connector is dry
After drying, do not rush to connect the phone to the charger.
- 🔦 Visual inspection. Light the jack with a flashlight, so there should be no drops, no condensation, no white plaque (a sign of oxidation).
- 📱 If it loads normally, without artifacts on the screen and spontaneous reboots, that's a good sign.
- 🔋 Connect the charging. Use the original Xiaomi cable and power supply. If the phone started charging, the problem is solved. If not, there was a moisture warning or charging is jerking, drying was not enough.
Some models (Xiaomi 12T Pro, Redmi K50 Pro) have built-in humidity sensors, sometimes helping to reset the water warning in the connector:
##6484## → «USB port setting» → «Clear»But this code doesn't work on all MIUI firmware, so if it doesn't work, dry your phone again.
| Sign. | What does it mean? | Action |
|---|---|---|
| Phone's off. | Moisture could damage the motherboard or battery | Carry into the service, do not try to charge |
| Charging is going, but slowly. | The connector or cable contacts have been oxidized | Clean the contacts with alcohol (only after drying completely!) |
| The “moisture in the connector” warning does not disappear | The humidity sensor is still working or is out of order. | Repeat drying or reset the sensor settings (see code above) |
| Phone warms up when charging | Short circuit or damage to the power controller | Urgently disable, not use until repair |
Oxidation of contacts: how to clean the charging connector
If you're drying your phone, it's not charging, or it's charging, it could be oxidized contacts, it looks like white or green plaque on the metal parts of the connector, and you're going to need to clean it up.
- 🧴 Isopropyl alcohol (90%+) or special liquid for cleaning contacts.
- 🧻 Cotton swabs or soft toothbrush.
- 🔍 Loop or flashlight for inspection.
Cleaning algorithm:
- Soak the cotton swab in alcohol and gently wipe the contacts in the connector.
- Allow the alcohol to completely evaporate (5-10 minutes).
- Repeat drying with the phone in an upright position for another 1-2 hours.
- Try plugging in the charger.
⚠️ Warning: Do not use vinegar, citric acid or acetone for cleaning - they are aggressive to metal and can accelerate corrosion. Also avoid mechanical cleaning with needles or toothpicks: this scratches the contacts and worsens their conductivity.
If the oxidation is strong and the alcohol is not helping, you can try specialized products, for example, Kontakt 60 or CRC 2-26. These are sold in electronics stores and are designed to clean contacts from corrosion.
💡
If the connector doesn't work after cleaning, try connecting the phone to another cable or charger, and sometimes the problem is the oxidized contacts of the power supply, not the phone.
When to contact the service center: signs of serious breakdown
Not all problems can be solved by yourself after water intake, but bring your phone to the service immediately if:
- 🔥 The phone does not turn on even after drying.
- 🔋 The battery swelled (the body deformed, the screen “steps away” from the frame).
- 📱 Artifacts appeared on the screen (stripes, flickering, broken zones).
- 🔊 The speakers or microphone are not working (a sign of water hitting the audio chip).
- 📡 The network is missing or not working. Wi-Fi/Bluetooth (Water could damage antenna modules).
Xiaomi's service center (or authorized partner) will run an ultraviolet light diagnostic that shows traces of fluid entering even after drying.
| Type of breakdown | Cost of repair (₽) | Timeline |
|---|---|---|
| Cleaning the charging connector | 500–1 500 | 1-2 hours |
| Replacement of USB-C connector | 1 500–3 000 | 1-3 days |
| Repair of the power controller | 3 000–8 000 | 3-7 days |
| Replacement of motherboard | 10 000–25 000 | 5-10 days |
If the phone is warranty-free but has traces of liquid (moisture indicators are working), repairs will be paid, and manufacturers (including Xiaomi) do not cover the damage from water intake under warranty.
How to Prevent Water Intake in the Future
Even if you managed to save your phone now, it is better to take care of protection in advance:
- 🛡️ Use a waterproof cover (e.g. Spigen Liquid Air or Spigen Liquid Air). UAG Pathfinder: They don't give you 100% protection, but they reduce the risk of splashes getting into the connector.
- 🔌 Close the plug (if it is included) on some Xiaomi models (for example, POCO X5 Pro) the connector is not physically protected.
- 🚿 Avoid using your phone in the bathroom, in the rain or near the pool. IP68 It will not save you from a long dive.
- 🔋 Regularly clean the connector from dust - it absorbs moisture and accelerates corrosion.
If you are often in high humidity (sports hall, beach, fishing), consider buying a smartphone with official IP68 protection.
- Xiaomi 13 Ultra (IP68),
- Xiaomi 12S Ultra (IP68),
- Redmi Note 12 Pro+ (IP53 – Splash Protection)
💡
Even IP68 phones are not designed to swim or shower, and water protection weakens over time (pads, connectors wear out), so avoid unnecessary risks.
