A flooded smartphone is one of the most common emergencies faced by Xiaomi owners. Even if your Redmi, POCO or Mi were in the water for a couple of seconds, the consequences can be fatal: from corrosion of contacts to complete failure of the motherboard. But don't panic! With the right actions in the first hours, the chances of saving the device are up to 70-80% (service centers data for 2023).
In this article, we'll take a step-by-step algorithm on what to do immediately after a flood, how to dry your phone properly, what mistakes make things worse, and when it's time to bring your gadget into service. We'll look at the security features of different Xiaomi models (including flagships and budget series), and we'll also give you a checklist to check the health after drying. Important: actions in the first 30 minutes determine whether you can save the device!
First steps: What to do in the first 5 minutes
If your Xiaomi falls in water, puddles, or even rain, time is playing against you. The fluid enters the body through speakers, connectors, and microslits, and the contact oxidation begins after you have been exposed to it. 10-15 Here's what we need to do right now:
- β±οΈ Get your phone out of the water as quickly as possible -- even a second matters. Don't wait for it to swim longer.
- π Turn off the power: press the switch on button 10-15 If the phone has already turned off, don't try to turn it on!
- π΄ Extract. SIM-card and memory card (if any) Use a paper clip or special key for the tray.
- π Unplug all the accessories: headphones, covers, chargers. The fluid can penetrate the connectors.
β οΈ Warning: Do not shake your phone, blow into connectors, or try to blow the water with a hairdryer at this stage, and this will only accelerate the fluid inside the case and increase the area of damage.
How to properly dry Xiaomi after flooding
Drying is the most critical stage, and 90 percent of the failures after flooding are due to improper drying, not the water itself. Here are some effective methods that actually work:
Method 1: Moisture absorbers (silica gel or rice)
- πΎ Rice: bury your phone in dry rice on 24-48 Rice will absorb some of the moisture, but it's a less efficient method than silica gel.
- π Silicagel (packages of shoe boxes or appliances): place the phone in a sealed bag with 10-15 baggy 48-72 Silica gel absorbs moisture in the 10 more efficient than rice.
- π§ Salt: an alternative to rice, but it can leave crystals inside the connectors. Use only as a last resort.
Method 2: Natural drying (recommended)
The best way to do this is to take the phone apart (if you have the skills) and dry the components separately.
- Place your phone in a dry, warm place (not on the battery!) with good ventilation.
- Turn it downwards so that moisture drains from the motherboard.
- Do not turn on at least 48 hours (24 hours for models with IP68 protection).
Why can't you dry with a hair dryer?
| Drying method | Time. | Efficiency | Risks. |
|---|---|---|---|
| silicagel | 48-72 hours | βββββ | Minimum |
| Rhys | 48+ hours | βββ | The little bits can get into the connectors. |
| Natural drying (disassembled) | 24-48 hours | βββββ | Requires disassembly skills |
| Fen (cold regime) | 10-15 minutes. | ββ | High risk of damage |
What to do if Xiaomi does not turn on after drying
If the phone doesn't show signs of life even after drying, don't panic -- there are several ways to resuscitate.
- π Charging: connect the original cable to the known working power supply. the charging indicator (if any) should catch fire.
- π Forced reboot: Press the power button + louden 20-30 seconds.
- π± Reaction to the connection to the PC: if the computer makes a connection sound USB-The device, the fee is partially operational.
If the phone vibrates but doesnβt turn on, the problem may be:
- π Battery (oxidation of contacts or failure).
- π± Display (damage to the plume or controller).
- π Pete motherboard (short circuit).
β οΈ Warning: If the phone heats up when connected to charging, disconnect the cable immediately! this is a sign of a short circuit and further attempts to turn on could finally kill the board.
Try charging from another power supply unit
Check the reaction to buttons (vibration, sounds)
Check the corrosion connectors (green/white coating)
Make sure that SIM-map and flash drive extracted
Prepare a check/guarantee (if any)

Common Mistakes That Kill Xiaomi After Water
Many users make things worse by doing the wrong thing, and here are the most dangerous mistakes that lead to permanent damage:
- π₯ Using a hair dryer in hot air - melts plumes and chips.
- π Connecting to charging until full drying - causes corrosion and short circuits.
- π¦ Attempts to turn on the phone "check" - even short-term power speeds up oxidation.
- π§Ή Cleaning with alcohol or liquids β if the water is already inside, the extra liquid will only moisten the board.
- βοΈ Drying on the battery or under direct sunlight - overheating deforms the battery.
It's especially dangerous to ignore corrosion, because the green or white coating on the contacts is oxidized metals that continue to break down the board even after drying.
- Clean the contacts with a cotton swab with isopropyl alcohol (90%+).
- For complex cases, use an ultrasound bath (only in the service!).
- Apply protective varnish to the contacts (for example, Contact Cleaner).

If the phone turns on after flooding, but quickly discharges or overheats, this is a sign of damage to the battery.
Xiaomi Water Protection Models: Whatβs Changing?
Some of Xiaomiβs flagship models have official water and dust protection on IP53 or IP68, but that doesnβt mean they can be safely put into water.
- π‘οΈ IP53 (For example, the Redmi Note 11 Pro+): Splash protection, not diving protection, and if you flood, just do it like a regular phone.
- π IP68 (For example, Xiaomi 13 Ultra: can withstand immersion for 1.5 meters for up to 30 minutes, but only in fresh water.
- β οΈ Protection weakens over time: after falls, repairs or wear of rubber gaskets, the protection class decreases.
Even if your model has IP68, after contact with water:
- Wash your phone with distilled water (if salt/sugar is involved).
- Dry for at least 24 hours (despite the stated protection).
- Check the speakers and microphones β they often fail.
π‘
IP68 protection does not cover water damage under warranty! the manufacturer considers this to be "misuse" even if the phone drowns in the bathtub.
When to contact the service: signs of critical damage
If after all the manipulations the phone:
- π Cyclically rebooting;
- π΅ Doesn't define SIM-map;
- π Distorting sound in speakers/microphone;
- π No charge is held (discharged for) 10-20 minute);
- π‘οΈ Overheating without loading,
- these are signs of serious damage to the board, and without professional repairs can not do.
The service center will perform:
- π Diagnosis of multimeter for short circuits.
- π§ͺ Ultrasonic cleaning of board from corrosion.
- π§ Replace damaged components (e.g., power controller).
- π Battery soldering (if contacts are oxidized).
β οΈ Warning: If the phone was warranty, don't tell the service it was sinking. You're likely to be sent for paid repairs".
Cost of repair after flooding:
| Type of damage | Cost (β½) | Duration of repairs |
|---|---|---|
| Corrosion cleaning | 1 500 β 3 000 | 1-2 days |
| Battery replacement | 2 000 β 5 000 | 1 day |
| Fixing (replacement of chips) | 5 000 β 15 000 | 3-7 days |
| Replacement of the display (if the plume is affected) | 4 000 β 12 000 | 2-3 days |
How to Prevent Flooding in the Future
To avoid facing this problem again:
- π± Use a waterproof case (e.g. Lifeproof or OtterBox).
- πΏ Donβt take your phone to the bathroom β 30% of flooding happens there.
- π¦ Avoid wet places: Do not put the gadget next to a cup of coffee, aquarium or on a wet table.
- π Check seals after falls β even a small chip can break the tightness.
- π² Set up quick actions: for example, double-pressing the power button to call SOS (Not to waste time unlocking in an emergency).
If youβre often at the water (on the beach, hiking, fishing), consider buying a special waterproof phone, such as the Xiaomi Black Shark 4 Pro (with improved protection) or models with IP68.

Xiaomi owners with a 3.5mm headphone jack: once flooded, this jack is oxidized first. If the sound is gone, clean it with alcohol or contact the service.
