It won't necessarily burn the motherboard, but there is a high chance that it will do.

After the mobile phone is turned on after water is in, the water in the electrical device will cause a short circuit and burn the electrical device. In addition, water will produce an electrolytic reaction under the action of electricity, which accelerates the corrosion of electrical devices and motherboard electric cover pants. Even if there are no electrical devices and motherboards are burned by luck, it will cause corrosion of electrical devices and motherboard circuits.

Therefore, the mobile phone cannot be turned on immediately after entering the water. Only when the water is dry and cleaned can it be turned on for testing.

How to deal with water after the phone is ingressive:

1. Quickly remove the battery or shut it down.

2. Remove the water on the surface, and remove the water inside as much as possible.

3. Put the phone and battery in a cool and ventilated place and let it dry. If possible, you can use a fan or fan to blow the mold dry. (Note: The fan should be at room temperature, not hot air.) The hot air will cause the water to seep into the motherboard to expand and damage the motherboard. ）

4. The mobile phone can be disassembled and hung with strong hands-on ability. And you can use a soft cloth to wipe off the water.

5. It is best to place the battery for 48 hours before using the pure wheel.

Why can I blow the motherboard when I dry it with a hair dryer? After the small area of the mobile phone is flooded,In fact, the water entering will not directly reach the inside of the motherboard,Although the headphone jack is large,But there is actually a certain degree of sealing inside Unicom,It will not enter directly,Generally, the charging port is far away from the motherboard,Even if the water is broken, the charging board will be broken first,It will not affect the trapped people to the motherboard。 When we use a hair dryer to dry the phone shell, the water will evaporate into water vapor, and the water vapor will diffuse to the inside of the phone and spread to the motherboard of the mobile phone, so that the area of water entering the mobile phone becomes larger.

The phone got into the water, but everything was still functioning normally. It is not possible to charge it, because some water may not penetrate the motherboard or circuitry, and if you rush to charge it, it will damage the machine or burn the machine. The line burned down.

It is recommended that you get into the water of the machine and its normal also put it in the sun. A ventilated place or a hair dryer to dry for a few days. Wait until the water in the water is completely dry and evaporate, and then recharge it, so that it is safer.

The most effective way to get water into your phone is to turn it off. Water is conductive, water into the motherboard of the power-on operation, it is easy to cause a short circuit of small components to burn out, after the shutdown of the mobile phone stopped running, it should save the phone's life.

Disassembling the phone is the only way to clean up the internal moisture, disassembling the phone and then using a hot air blower to purge the motherboard, so that the water in the motherboard can completely evaporate. You can master the basic disassembly skills of the mobile phone according to the online tutorial, and the mobile phone should be disassembled and cleaned up as soon as possible after entering the water.
