How to charge iphone 7 after water The apple 7 is charged after water is in water

The Apple 7th generation is waterproof, if there is not much water intake, it can be no problem, and it can be charged at any time as long as the external moisture is wiped dry.

But if there is a black screen after entering the water, it will not turn on, restart, and the screen will not move.

It's likely that there is a problem with the screen or motherboard.

Since water ingress is not covered by the after-sales warranty, it can only be repaired at a cost.

Pay special attention to motherboard maintenance, and don't replace the entire motherboard as soon as you hear that the motherboard is broken.

If the motherboard is broken, don't be afraid, the motherboard is not a whole piece, there are many small chips in it, including baseband, CPU, hard disk, WiFi module, touch screen IC and so on.

Many small local masters don't know how to repair chips, so they let the entire motherboard be replaced, which is very expensive.

In fact, you only need to change the chip, which can save more than half.

The yellow chip in the picture below is the most common power supply IC, and if it is burned, the screen will be black and will not turn on, just change it.

I have been doing mobile phone chip repair, and I know these very well.

Precautions for charging iphone7 after water intake:

1. According to Apple's official documentation: "If your iPhone 7 or iPhone 7 Plus has been exposed to liquid, please unplug all cables until it is completely dry before charging."

Using the accessory or charging in wet conditions may damage your iPhone, please dry it for at least five hours before charging or connecting the Thunderbolt accessory. ”

2. In fact, some other brands of waterproof mobile phones have similar regulations, so this is not surprising.

It is worth mentioning that although the iPhone 7 is waterproof, the damage to the device due to water ingress is not covered by the warranty, and Apple also reminded that the iPhone 7 will decrease in waterproof performance as the use time increases.

If the iPhone accidentally gets into the water, you should turn off the phone immediately, place the phone screen down horizontally, wipe the phone with a dry towel, dry it with a hair dryer, and then send the phone to the repair center as soon as possible for a professional to repair.

Friends who have a hair dryer around you can simply blow the iPhone with hot air, pay attention to blowing in all directions, and blow the hair for the headphone jack, speaker and other parts. Be careful to keep a certain distance, and remember not to blow a little too much for too long. The iPhone 4 4S with the back cover removed can also be blown, remember to keep a certain distance and blow evenly.

How to deal with the water after the iPhone is ingressive.

1.Turn off the phone as soon as possible, cut off the power, and do not try to turn it on again to avoid causing a short circuit in the motherboard.

2.Remove the SIM card and use a tissue or cloth to remove water from the outside and crevices of the phone.

3.If there is light water ingress, you can wrap the phone with a paper towel, put it in a bag and put it in a small bag of desiccant.

4.The mobile phone cannot be turned on after entering the water, most of the chips such as the motherboard and CPU are short-circuited and burned, and it is recommended to send it to the after-sales service center for repair immediately.

Don't try the following wrong methods after your phone gets into water.

1.Don't shake your phone too hard. Because under the constant shaking, the liquid will swim inside the machine, and the moisture may enter deeper and burn the internal chip of the machine.

2.Don't use the hot air of a hair dryer to dry your phone for a long time. iPhones are now all metal bodies, and metal conducts heat easily, which will blow off the solder joints of the motherboard inside the machine, causing the motherboard to malfunction.

3.Do not attempt to charge a phone that has been flooded. An iPhone that gets into the water may have water stains inside, which can burn out the motherboard when it is powered on and cause a more serious failure.

4.Do not leave your phone in water for a long time. In the case that it cannot be used normally after two or three days after general treatment, it should be sent for repair immediately, and long-term placement will cause the motherboard to be corroded, or even unable to be repaired.

1. If the iphone7 or iphone7plus has been exposed to liquid, please unplug the closed cable until it is completely dry before charging. Using the accessory or charging in wet conditions may damage your iPhone, please dry it for at least five hours before charging or connecting the Thunderbolt accessory.

2. Some mobile phones can be turned on and used normally after simple treatment, but the mobile phone is composed of precision electronic components, and there is a hidden risk after entering the water, so it is recommended not to try to turn it on.

3. If you encounter software problems after booting, don't panic, shut down, remove the battery, try to change the SIM card and memory card, or it doesn't work, don't bring the battery, wrap the mobile phone, it is best to put a small food in the "desiccant", and then take it to the nearest customer service maintenance office to deal with it, and your own blind random press will make the situation worse.

1. Fish out the mobile phone as soon as possible, and reducing the time of contact between the mobile phone and water will minimize the damage to the mobile phone. The longer the phone is immersed in water, the more harmful it will be to the phone's earpiece, microphone, screen, and motherboard.

2. Quickly wipe the water marks on the surface of the mobile phone, and remember not to open the mobile phone. If you turn on the phone immediately, even if the phone itself is not damaged, once it is turned on, it may cause the motherboard to be burned.

3. After taking out the mobile phone, regardless of whether the mobile phone is turned on before it is dropped, quickly remove the battery. Now most of the mobile phone design is integrated, the battery is not professional can not be taken out, if you do not have rich experience in disassembly, it is recommended not to disassemble, so as not to cause greater damage.

4. Use a hair dryer to keep the temperature of your hands not hot, blow on the hole in the phone, blow 3 times, 3 minutes each time. Then start to do the drying process.

5. Try to turn on the phone, if it can't be turned on normally, go to the mobile phone store in time to repair the cherry acres.
