You dropped Xiaomi in a water, bath, or puddle, and now the phone doesn't turn on, it's glitchy or dead? Don't panic: the first 30 minutes decide everything. Even if the gadget doesn't have official IP68 protection, there are chances of salvation, provided you act quickly and correctly. In this article, we'll break down the step-by-step algorithm for different scenarios (from easy moisture to complete flooding), tell you what mistakes will kill the device forever, and what to do if the phone doesn't react.
Important: Modern Xiaomi smartphones (including the Redmi Note series, POCO and Xiaomi’s flagship 13/14) often have partial spray protection, but this does not guarantee survival when fully immersed. Even IP53-labeled models (such as the Redmi Note 12 Pro+) can fail from salt water or prolonged contact with liquid. So don’t believe the myths of “self-drying in a week” – without the right actions, corrosion will destroy the fee in 24-48 hours.
Below you will find emergency checklists, water compatibility tables, and diagnostic and repair tips, and if the phone is still on, watch for signs of late breakdowns (such as sudden reboots a month after the incident).
Step 1: Immediate action in the first 30 minutes
The speed of the reaction is critical, and every second increases the chances of survival.
- 🚨 Pull the phone out of the water -- even if it's still working. Don't press the buttons, don't try to unlock the screen.
- ⚡ Turn off the power: press the power button for 10-15 seconds to force the device to turn off. If it doesn't respond, don't waste time, move on to the next step.
- 🔌 Extract. SIM-card and memory card (if any): moisture can damage them, and contacts - close.
- 📴 Do not shake or blow into the connectors - this will spread water inside the case.
If the phone was in salt water (sea, aquarium), carbonated drinks or soap solution, the situation is worse than when immersed in fresh water. Salts and sugar accelerate corrosion by 3-5 times. In this case, you can not wait: after extraction, immediately rinse the case with distilled water (or boiled if there is no other) and go to dry.

⚠️ Warning: Never use a hair dryer, microwave or heating battery to dry! Local overheating will warp the screen, melt the glue under the battery and speed up the oxidation of contacts.
Step 2: Disassembly and drying – what you can do yourself
If you have experience in disassembling the equipment, you can speed up the drying by removing the back cover. For most Xiaomi models (except for flagships with adhesive body, for example, Xiaomi 13 Ultra) you will need:
- 🔧 Plastic blade (or mediator)
- 🧲 Screen suction cup (optional)
- 🔥 Fryer with cold blown (temperature not higher than 40)°C)
- 🧻 Waxless napkins or toilet paper
How to make out:
- Heat the back cover with a hair dryer (1-2 minutes) - this will soften the glue.
- Insert the blade into the gap between the case and the screen (start at the corner next to the power button).
- Carefully walk around the perimeter, separating the lid. Don't force - the glass may crack!
After the disassembly:
- 📱 Put the phone down on a dry wipe.
- 🔋 Remove the battery (if possible) – this will prevent short circuit.
- 💧 Wet the visible moisture with wipes, do not rub!
- 🌬️ Leave to dry in a well-ventilated place for 24-48 hours.
What to do if you can’t take the phone down?
| Xiaomi model | Degree of protection (IP) | The chances of rescue after flooding | Recommendations |
|---|---|---|---|
| Xiaomi 13/14 Pro | IP68 | 80–90% | It will withstand a short-term dive (up to 30 minutes at a depth of 1.5 m). After the incident, wash with fresh water and dry. |
| Redmi Note 12 Pro+ | IP53 | 40–60% | Splash-only protection. When fully immersed, disassemble and dry for at least 48 hours. |
| POCO X5 Pro | No defense. | 20–40% | Remove the battery quickly, silica gel drying is mandatory. |
| Xiaomi 12S Ultra | IP68 | 70–85% | The camera is vulnerable. After the water, check for focus and stabilization. |
Step 3: Diagnostics After Drying – How to Know if Your Phone Is Alive
Even if the phone is turned on, it is not a guarantee that it is fully functional, late breakdowns can manifest in a week or a month.
- 🔋 Battery: Connect charging. If the phone doesn't charge or shows 0%, battery degradation is possible.
- 📶 Network and sound: Check signal strength, speakers and microphone (record voice message).Muffled sound or lack of network is a sign of oxidation of antenna contacts.
- 🎮 Sensor and buttons: Walk across the screen, press all physical buttons. Sticking or broken zones signal damage to plumes.
- 📸 Camera: Take a photo of each camera. Blurring, artifacts or "failed to connect to the camera" error is a reason for repairs.
For deep diagnosis, use service codes:
#4636## - information about the battery and network
#6484## - Sensor test (for some models)
#64663## - Camera module test💡
If the phone turns on after flooding but discharges quickly (from 100% to 0% per hour), the charging controller is likely damaged, in which case do not use fast charging - this can cause the battery to burn.
⚠️ Warning: If after drying, the phone turns on, but heats up more than usual or reboots itself, turn it off immediately! These are signs of short circuit on the board. Further use can lead to irreversible damage to the processor or fire.
Step 4: When to contact the service - signs of malfunction
Not all breakdowns after water can be repaired by yourself.
- 💥 The phone doesn’t turn on even after 48 hours of drying.
- 🔥 There is a smell of burning or smoke from connectors is visible.
- 📵 The screen flickers, shows artifacts or doesn't respond to touch.
- 🔋 The battery swelled (seems to be on the raised back cover).
- 💦 There are drops or divorces under the screen (even if the phone is working).
The service will do:
- Ultrasonic cleaning of board from oxides (cost: 1,500–3,000) ₽).
- Replace damaged components (power controllers, antenna modules).
- Diagnosis of the battery - when it is bloated, it will be replaced (price: 1000-2 500) ₽).
- Pressurization check (for models with IP68, seals may need to be replaced).
The cost of repair depends on the model:
- Redmi Note: 3 000–8 000 ₽
- POCO X: 4 000–10 000 ₽
- Xiaomi 13/14: 8 000–15 000 ₽ (because of the complexity of the board and the cameras)
💡
If the phone is warranty, do not tell the service about the water — this automatically cancels the warranty.
Step 5: How to Prevent Corrosion – Long-Term Measures
Even if the phone is working normally after drying, contact oxidation may occur later to minimize the risks:
- 🛠️ Check the speakers and microphones once a month, they are the first to suffer from corrosion.
- 🔌 Use wireless charging (if supported) to avoid loading the connector USB-C.
- 📉 Watch for battery life – if it is reduced by 30% or more, the battery is damaged.
- 💧 Avoid high humidity (for example, don’t leave your phone in the bathroom while showering).
For unprotected models (POCO M5, Redmi 10A), consider buying a sealed case (e.g. Lifeproof Fre or OtterBox Defender).They will not save you when fully immersed, but will protect you from splash and rain.

Step 6: Myths and Mistakes – What Will Kill Your Xiaomi Forever
The Internet is full of advice that will only make things worse.
- 🔥 Dry in rice: grains of dust will clog the connectors, and moisture will remain inside.
- ❄️ Put in the freezer: condensate during defrosting will accelerate corrosion.
- 🔌 Connect to charging immediately after extraction - short circuit guaranteed.
- 💨 Use a vacuum cleaner: static electricity will hurt the fee.
- 🔧 Disassemble without experience: you can tear plumes or damage the screen.
Also avoid “folk” remedies such as:
- 🧂 Sprinkling with salt (causes corrosion).
- 🍺 Washing with beer or vodka (sugar and alcohol destroy contacts).
- ☀️ Drying in the sun (UV rays spoil the screen and battery).
💡
If you pour coffee, tea or sweet soda on your phone, wash the case with distilled water with 10% vinegar (1 part vinegar to 9 parts water), which neutralizes the sugar and slows corrosion. After washing, immediately dry with silica gel.
