If the mobile phone is flooded, it is best to use a hair dryer to dry it, do not turn on or charge it, the water ingress of the mobile phone will cause a short circuit in the connectors and the battery. If there is no sound from the earpiece, it may be that the external components of the earpiece have poor oxidation contact after water ingress, and it is best to go to a professional repair shop for inspection.

Use a hair dryer to blow it, but don't get too close to the phone to avoid damaging the battery and phone screen.

The temperature of the wind blown by the hair dryer is still relatively high, basically equivalent to the temperature when the mobile phone is most seriously heated, the closer to the tuyere, the higher the temperature, and it is not impossible to be scalded by the hair dryer, so when blowing the mobile phone, you must pay attention to the distance between the hair dryer tuyere and the mobile phone, so that the wind temperature blowing on the mobile phone is close to normal temperature. Remember not to blow the air vent of the hair dryer directly on the phone, too high a temperature is absolutely not good for the phone.

Precautions for using mobile phones.

Charge the battery often: Don't wait until your phone battery runs out to charge. Generally, we have an idea that it is better to charge the battery of the mobile phone after all the power is discharged, which is basically true, because most of the rechargeable batteries we used in the past are nickel-metal hydride (NIH) batteries, and nickel-metal hydride batteries have the so-called memory effect, if you do not discharge and recharge, it will lead to a rapid reduction in battery life.

If you still wait until all the electricity is used up before charging, it will make the chemicals inside the lithium battery unable to react and reduce the lifespan. The best way to do this is to charge it when it's okay and keep it in the best possible state at all times, so that the battery can last a long time. This is the information obtained from the manufacturer and tested by itself.

Use a hair dryer to keep your hands at a temperature that is not hot and blow on the phone where there is a hole, 3 times for 3 minutes each time. Then start to do the drying process.

Keep the phone in a cool, dry place for 24 hours, and if there is no hair dryer to dry the water, it is best to leave it for 48 hours.

If the mobile phone is in water, you can put it in the rice, the reason is that the water absorption of the rice is relatively good, and the mobile phone buried in the rice can help to absorb all the remaining water droplets and water vapor inside the mobile phone.
