What are the common faults of iPhone?

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.

If the BAI heating power supply current of the iPhone hard disk is not turned on, remove the C0617 capacitor DU next to the hard disk;

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.

In general, this is by putting your Apple iPhone into recovery mode and then flashing it with iTunes. Please press and hold the power button on the top of your iPhone first, and then slide to power off when the power off option comes out.

After shutting down, the next step is to start the operation steps to enter recovery mode

1. Press the power button to turn on, the Apple logo will appear on the screen, do not release the power button;

2. Then press and hold the home button on the home screen until the screen goes black.

3. When the screen is black, please release the power button and continue to press and hold the home button on the home screen until iTunes on the computer side detects an iPhone in recovery mode;

Note: If you don't enter recovery mode, it turns on normally, please try a few more times.

To flash an Apple iPhone, you'll need to recover your files. This file can be done manually or by iTunes itself. You can flash your phone either way, and you may be able to do it manually faster than iTunes.

Here's how to get iTunes firmware automatically restored for your iPhone. In the iTunes window, click the "Restore iPhone" button, then iTunes will connect to the Internet to detect the latest firmware system suitable for the current phone, and prompt us if we want to delete all data and restore, click the "Restore" button to start, then please wait patiently for the iTunes** firmware, and flash the firmware system to the Apple iPhone.

Summary. 1. Apple analyzes data failures** method: Open Settings - Privacy - Analysis - Analyze Data.

2. Find the data that starts with "panic-full-**". 3. With the appearance of this data, the problem is that the bottom layer of the motherboard is broken, and the contact will be bad, which will cause the machine to restart indefinitely, that is to say, it is a time bomb. 4. Analysis data of a normal original machine, without the beginning of "panic-full-**".

5. All those who say that if you want to buy a second-hand mobile phone, you must have some basic mobile phone common sense to avoid being fooled by unscrupulous merchants, because this kind of machine is commonly known as a bomb machine, and the goods are lower than the normal machine.

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. If the motherboard of the older mobile phone is broken, it is better to throw it away and replace it with a new one, and it is not cost-effective to repair it.

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.

When the microphone fails, we can first check it ourselves to see if the microphone is damaged.

1. We must first understand that the iphone mobile phone microphone is in**, how many are there. There are a total of 4 on the iPhone 7Plus mobile phone, two of which are at the bottom of the phone, one next to the front earpiece, and one next to the rear camera, each microphone has a different function.

2. Check whether each microphone of the iphone7plus mobile phone is faulty, and we will test it in turn. Note: Make sure your phone is not plugged into headphones or connected to Bluetooth headphones.

6. If the above detection microphones are normal, but your voice cannot be heard by others when playing ** or you cannot prepare to hear our voice clearly when using Siri, then you can see if there is any dirt or blockage on the microphone next to the front earpiece and the microphone next to the rear camera.

1. Turn off the silent mode, 1. First click the "Settings" icon on the desktop of the mobile phone, General - > Accessibility - > AssistiveTouch settings are turned on, the screen floating button appears, click on, select the device in the tile - > Unmute, cancel the mute, so that this problem can be solved.

3. After entering the sound interface, slide the slider in the red box below to the right to turn off the silent mode. Of course, you can also use the button in the mobile phone to mute the sound in a quick way, next to the mobile phone, as long as you dial down first.

2. Upgrade the phone's system to the latest, then turn it off and restart it, and then check if the phone is silent.

If the above methods can't solve the problem, it is recommended to bring the mobile phone and warranty card to the official repair center of the Apple mobile phone for maintenance.
