When a cell phone accidentally enters the water, we can take the following urgent measures to avoid secondary injuries:
First, mobile phones are immediately placed in dry ventilated areas and dry paper towels or towels are used to wipe surface water stains。
2. If the mobile phone is on the switch, press the power button immediately and, if so, do not attempt to turn it on。
3. Timely removal of sim and microsd cards。
4. Carrying mobile phones as soon as possible to the authorized post-sale department so as to avoid unnecessary losses。
The following points require attention:
1. Do not shake or shake mobile phones frequently to prevent water from spreading into the interior。
2. Do not treat high-temperature items such as wind blowers or stoves in order to prevent liquids from entering the interior and causing high-temperature damage。
3. Although some mobile phones remain functional after simple processing, there is a potential risk that they will be released, and it is therefore recommended that no attempt be made to turn them on。
4. After-sale maintenance may result in the loss of data and staff are advised in advance how to back up the data。

1. Do not attempt to turn the engine on immediately when water is in. Because iphones are built-in batteries that cannot be removed, the main board will be short-circuited if it is opened to burn the main plate, with irreparable consequences。
2. A toilet paper can be used to dry the water outside the cell phone, and then the cell phone screen can be placed down horizontally to prevent the flow of water to the main plate, and then the drying of the water will open the medium or small temperature。
3. Use waterless alcohol to wipe circuit boards and so forth to try to turn them on. The water on the circuit boards can be wiped out together because of the relatively rapid volatility of alcohol。
Delivery to the maintenance centre for repairs as soon as possible. Longer periods of time can lead to irreversible consequences when the main plate is seriously corroded。
The reason for the failure of the apple phone and the solution:
1. Unnormal viewing: the use of off-grid power to power mobile phones, the use of itu tables to check if there has been any change in the signal numbers, and if there is no change, it is likely that the opening line has been broken or the opening key has been in poor contact。
Battery power supply is irregular: using an external interface to power the cell phone, to see if it's back to normal when it's on, and if it's normal, it's an abnormal circuit。
3 the ic of the cell phone power is abnormal: a comparison of the path map is tested at the test point of the ex-ic perimeter circuit to see if the test value is normal。
4. The system clocks and resets of the mobile phone are abnormal: the cpu power source of the mobile phone can be tested using a two-sum oscillator to see if the wave pattern is correct。
5 -- logical circuit problems: mobile circuits are out of trouble, which can be solved by welding。
6. Software conflict: a failure to match the installed software with the mobile phone system may also result in a failure to turn the cell phone on, allowing the computer to connect the cell phone to delete the program。
The iphone11 water is in, and if the water does not enter the cell phone, it will be fine。
If you get inside the cell phone, it can cause corrosive tail plugs, short circuits, burning batteries, etc
