In this article, we will take specific actions to help save the Redmi 9A with the highest probability.

• ⚡ Signs of malfunctions after “water procedures” and how to diagnose them.

Important: Redmi 9A doesn't have official IP-certified water protection, so even a short dive can have serious consequences, but there's a chance of survival if you act quickly and correctly.

Step 1: Immediate Action – First 30 Seconds

The speed of your actions depends on whether the phone will remain functional.

Getting your phone out of the water (NOT PUTCHING!)|Turn off power (click the switch on 10-15 seconds)|Extract SIM-card and memory card (if any)|Don't shake or blow into the connectors|Put the phone up on a dry surface-->

⚠️ Critical error: Many people try to turn on their phones to "check," which is equivalent to a death sentence for the device, and the water inside the case when power is applied causes short circuits that burn the chips. Even if the phone is turned on, turn it off forcibly (press the power button on 10).+ seconds).

If the toilet was with water "with additives" (cleaners, fresheners), wash the phone with distilled water or alcohol solution (isopropyl alcohol 90%+). This will help remove aggressive chemicals that accelerate corrosion. But do this only if you are sure that the alcohol will not get on the screen (it can damage the oleophobic coating).

💡

If you don't have isopropyl alcohol on hand, use vodka (at least 40°) - it contains enough alcohol to partially neutralize the impurities.

Step 2: Disassemble your phone (if you’re willing to take a risk)

The ideal option is to take the Redmi 9A to the service center within an hour of the incident, but if you decide to disassemble the phone yourself, follow the instructions:

1. Remove the back cover. The Redmi 9A has it on the latches, so stick it with a plastic spatula (or guitar mediator) on the bottom edge where the charging connector is located. Don't use metal objects, they'll scratch the body.
2. Disconnect the battery. The battery in the Redmi 9A is glued, but it can be gently tampered with. Don't puncture the battery under any circumstances - it's dangerous!
3. Wet the visible moisture with wipes or cotton pads. Pay special attention: 🔋 Battery contact and power connector. 🎤 Microphones (top and bottom). 🔊 Dynamics and vibrator.

⚠️ Warning: If you've never taken your phones apart, don't take any risks. Wrong actions can damage plumes or tear off small parts. The service will take 10-15 minutes to disassemble, with a guarantee.

After wetting, leave the phone in a dry, warm place (but not on the battery or in direct sunlight!).The ideal temperature for drying is 25–30°C. Avoid:

• 🔥 Fryer (hot air can warp plastic and damage screen).
• 🍚 Rice (it's a myth - it doesn't absorb moisture from inside the case).
• 🧊 Refrigerator (condensation will exacerbate the problem).

Step 3: Drying the phone – how long does it take?

The minimum drying time is 48 hours, but it's better to last 72 hours, especially if the phone has been in the toilet with detergents.

⚠️ Warning: Do not turn on the phone to "check" while drying. Even if it is externally dry, moisture may remain under the screen or on the board.

Step 4: Checking your phone after drying

After drying, take your time to rejoice.

1. External inspection: Check if there are any moisture droplets under the screen (visible in bright light at an angle). Check the charging connector for green plaque (a sign of corrosion).
2. Test turn on: Connect the charger. If the phone doesn't respond, there's a problem with the board or battery. If the red light goes on but doesn't turn on, maybe the power controller has burned.

Verification of functions

• 🎤 Microphone: Record a voice note and listen (muffled sound) = microphone-water).
• 🔊 Speaker: Play music (wheezing or no sound) = problem).
• 📶 Network: Check signal strength (if no network is damaged) RF-module).

If the phone turns on but is not running smoothly (rebooting, warming, not charging), these are signs of hidden damage to the board.

• 🛠️ Backup your data immediately (photos, contacts, messages).
• 📱 Take to the service for ultrasonic cleaning board (cost - from 1500) ₽).

Step 6: How to avoid recurring problems?

If you have managed to resuscitate Redmi 9A, follow these tips to prolong its life:

• 🔌 Use waterproof covers (such as Spigen Liquid Air or Spigen Liquid Air). UAG They won't save you when you're fully immersed, but they will protect you from spray.
• 🚿 Avoid using your phone in the bathroom or toilet. If you need to answer your phone urgently, put it on a dry surface away from the water.
• 🔋 Check the charging connector regularly for moisture or green plaque. At the first sign of corrosion, clean the contacts with alcohol solution.
