1. There is no response when the device is turned on.
When you encounter an iPhone that automatically shuts down, no matter how you press the power button, there is no response, isn't the phone broken in this case?
Connect your iPhone to the computer with a data cable, and it will start automatically. You can also keep the power button and home button for a few seconds at the same time, and there is a chance that a white Apple logo will appear.
2. The iPhone screen is unresponsive.
Sometimes when I play with my phone, suddenly the screen of my iPhone loses its responsiveness, and I can't move forward or return. At this time, you can try to press the home button and the power button at the same time to force the shutdown until a white apple appears on the screen. In addition, this method can also clear some basic caches, if you often use your iPhone to watch**or watch**, you can try this method occasionally.
3. The mobile phone is hot.
This problem is very common because it can happen with both old and new iPhones, because it is normal to get hot when using the phone, but if it is hot, it is a different matter. Let's take a look at how to deal with fever:
Reduce the time you spend playing games on your iPhone, which is the most expensive processor on your phone, so generating heat is inevitable.
Turn off GPSGPS is actually the main culprit of iPhone fever, and it is also a major cause of battery consumption, even better.
Remove your phone from the cover to help cool your iPhone
Avoid calling your phone while charging. Generally speaking, the heat of a mobile phone is emitted by the phone's battery and processor. If you play with your phone while charging, the heat of your iPhone may increase.
Try to avoid using your iPhone in a high-temperature environment
4. The mobile phone consumes too much power.
In general, there are two reasons for fast battery consumption, one is that the screen brightness of your phone is high and some unused functions are still turned on, and some applications reside in the background, which will make the iPhone consume too much power.
The second kind of firmware damage, it may be that there is leakage on the motherboard, the display of battery power is incorrect, the battery is damaged, etc., we can't know which firmware is damaged, so we can only send it to the Apple after-sales repair center for testing and repair.

In the process of using Apple mobile phones, there may be problems with the hardware or software of the mobile phone, and the mobile phone will occasionally have a black screen. When there is a crash, how do we solve it? I'd like to introduce it to you today.
After you master these methods, you will be able to better deal with and use the phone when the screen appears black, and restore the phone to normal use as soon as possible.
Method. 1. Force the phone to restart.
When the Apple iPhone freezes and there is no response, at this time we can try to press and hold the "Power and Home Screen" button of the phone at the same time and keep it for more than 10 seconds. If the force restart is successful, you can see an Apple logo on the screen. After the reboot is successful, you can use the phone normally.
In addition, for some friends who like jailbreaking, you may often encounter the problem that your phone freezes and restarts automatically. In addition, I like to be a guinea pig, and when I update the iOS test firmware, there is a chance that there will be a black screen of crashes. These failures can be solved by trying this method first.
Method. 2. Charging.
Of course, sometimes it may be because the phone is out of battery, resulting in automatic shutdown, no matter how we operate, it can't turn on. When this happens, please plug your Apple iPhone into a power charger first. If the battery is automatically turned off because it is out of power, a battery icon will appear on the screen.
In addition, the battery of the iPhone needs to be charged to more than 5% before it can be turned on normally, if the battery is very low, please let it charge before turning it on. If there is still no response on the screen after connecting the charging power supply for the Apple mobile phone, then press the first method to operate, and press the "Power + Home Screen" button at the same time, and hold it for more than 10 seconds. If you can't solve it, you can test it with an external power supply.
If it can be turned on, it is a problem with the battery, and the battery can be replaced.
Method. 3. Hardware failure.
If the above two methods work, it may be a hardware failure of the Apple mobile phone, and it is recommended to send the mobile phone for repair to an Apple authorized after-sales service store for testing.
Method. 4. Exit recovery mode.
The iPhone system sometimes enters recovery mode, this we can use the method of exiting the recovery mode, and press the power button and the home button at the same time for 10 seconds.
When there is a black screen on our love machine, if the mobile phone is used during our warranty period, it is recommended that you take it to the Apple mobile phone after-sales service center for warranty. After all, the relevant technicians at the warranty point must be more professional, but the general warranty may take a long time. If your phone has passed the warranty time, it is recommended that you try the above treatment methods, of course, you must find the cause of the black screen of the mobile phone before solving it, and then you can quickly solve the problem of the black screen.

How much does it cost to repair the bottom wire of the motherboard.
Hello, the motherboard is the most important part of the mobile phone, it takes about 200-300 to change the motherboard, 1000-2000 mobile phones, the motherboard is about 300-500, and the mobile phone above 2000 is about 400-600 to change the motherboard.

The traffic "runs" fast (turn off the "notifications" function in the iPhone settings to reduce automatic networking).
There is no sound when you call, and the call needs to be hands-free to hear the sound (this situation is generally caused by the moisture of the mobile phone and enters the headphone mode.) You can use the electric air to blow the hot gear against the earphone jack and the tail charging port for a period of drying).
The camera is not working (go to Settings - General menu and select Reset Phone, it will fix the problem).
Heat up (turn off background programs that are not in use).
Crash (force Apple's device to shut down by pressing and holding the "Power On" button and "Home" button for more than ten seconds).
In addition to the above problems, Apple phones will also have a red and blue screen phenomenon (restore the phone firmware), the phone screen flashback (go to the software running in the background, manually turn off part of the running software) and so on. Generally, after the problem with the mobile phone, you can choose the method of booting and restarting the phone, and try it first.
