Summary. One situation where the iPhone itself is unstable, resulting in a black screen. This kind of black screen can be attributed to an unstable automatic shutdown, which is because the machine is of poor quality, resulting in shutdown for no reason.

Because there is no big problem with the hardware, you can just press and hold the power button and wait for it to turn on.

The second scenario. DFU mode is the mode in which the Apple system cannot be turned on if there is a problem, while entering the recovery mode can be recovered with iTunes. But the phone is fine, and it can't be turned on because it can't be turned on because it has entered DFU mode by mistake, but it's actually very easy to solve.

You only need to press and hold the power button and the home button at the same time and wait for the iPhone to react, generally for more than 10 seconds, if there is no response for tens of seconds, the following steps continue.

In the third case, you need to enter DFU mode, first of all, iTunes must be installed on the computer, and you can ** a new iOS system. Or restore files with a backup beforehand. Of course, during the recovery process, the computer can be connected to the Internet, and it can also be ****, but the wait is longer.

The iPhone suddenly goes black but is powered on: because the device is overheating, the internal temperature of the device is beyond the normal operating temperature range, and the device tries to adjust its own temperature to protect the internal components.

1) Charging (including wireless charging) slows down or stops.

2) The display screen is dimmed or black.

3) The cellular mobile radio component enters a low-power state. During this time, the signal may become weaker.

4) The camera flash is temporarily unavailable.

5) Slower performance when using graphics-intensive or augmented reality apps or features.

In general, it may be due to the battery running out, resulting in a black screen that cannot be turned on.

If this is the case that we can't turn on, please connect the phone to the power first, if you see a charging sign on the screen at this time, and the battery is very low, it means that the battery is dead.

Some friends think that after connecting the power supply, they can turn on normally. In fact, if you use up all the battery power, the charge needs to be charged to 5% before it can be turned on normally. So in this case, please let the phone charge for a while before turning it on.

If you are sure that the current battery of your phone is sufficient, but it cannot be turned on normally, there may be a problem with the software system of your phone. At this time, we can try to press the "Home and Power" button of the mobile phone at the same time until the screen is lit up and displayed.

If the above operation method does not work, at this time we can also connect the phone to the power supply, and then press the power and home button on the home screen at the same time to see if it can be turned back on.

If it still can't be turned on, it is recommended to send it for repair.

As long as you press and hold the power button and the exit button (home) at the same time for about 10 years, it will force the shutdown and then restart it. However, it is generally not recommended to force a shutdown. There is an impact on mobile phones.

The solution to the black screen of the iPhone:

If you enter DFU mode, you will exit according to the exit method of DFU mode.

If the screen is normally black, try connecting the phone to the computer iTunes or press and hold the power button until it can turn on.

If you accidentally press the recovery mode and cause a black screen, press and hold the home button and the power button together, press and hold together for about 15 seconds and let go, and then press the power button to recover.

The black screen is basically a software problem, the boot button + home button.

Press and hold at the same time for 10 seconds. Look.

None of the above methods work, just use iTunes to restore the system.

It may be an occasional phenomenon, restart it and try it, in addition, when the power supply is low, the screen will suddenly go black, if the screen is always black, it is recommended to repair, and the occasional is not a problem.
