What to do if your iPhone falls into water

　　Things to note if your iPhone falls into water:

　　1. Take the phone out of the water as soon as possible, and take out the battery and SIM card immediately to prevent line short circuit and contact loss.

　　2. If the iPhone falls into drinkable fresh water, the problem is not big. If it falls into salt water such as sea water, once a "salt crust" forms in the internal components of the phone, it will be very troublesome to clean up. If you are one of the unfortunate ones, you can rinse the phone with fresh water, of course after taking out the battery and SIM card.

　　3. Wipe the inside of the phone with a clean cloth or paper towel. Do not move or shake the phone too much to avoid water flowing inside the phone.

　　4. Wrap the iPhone with a clean cloth or paper towel to create a small vacuum effect to suck out excess moisture. It is best to place it in a warm place.

　　5. You can put a waterlogged iPhone into a rice jar for 24 hours. Rice has good water absorption and can save a damp phone. Of course, you need to turn off the phone before putting it in.

　　6. Try to turn on the phone after 24 hours after entering the water. If the battery cannot be charged, you must replace the battery.

　　7. There is a small white dot near the battery compartment. If it turns red, the maintenance personnel will know that it is not a quality problem with the equipment, and all subsequent repairs will have to be paid for by themselves.

　　Four steps to rescue an iPhone after it falls into the water:

　　Step one: Take the phone out of the water and remove the battery as quickly as possible.

　　Step 2: Take out the SIM card of the iPhone, wipe it with a paper towel and place it in a ventilated place to dry.

　　Step 3: If you are familiar with the internal structure, you can disassemble the internal accessories and dry them for better results.

　　Step 4: Under normal circumstances, the above three steps can basically solve the problem if it has not been soaked in water for too long. If it cannot be turned on normally, the motherboard may be broken and it needs to be handled by a repair station.

　　Four taboos for dropping an iPhone in water:

　　The first taboo: blowing with hot air from a hair dryer or exposing it to the sun will cause the circuit board to deform.

　　The second taboo: Do ​​not press the power button to shut down the device. Once the shutdown button is pressed, the device will start working and a short circuit will easily occur, causing damage to the motherboard.

　　The third taboo: Do ​​not frequently turn on the phone for testing within 24 hours after falling into the water. Wait at least 1 day before installing the battery for testing.

　　Fourth taboo: Do ​​not press any keys before the device is dry to prevent short circuit and damage to the motherboard.
