In the event of an automatic restart of Apple, it is recommended to deal with it in the following ways:

After connecting the mobile phone with the computer, and then press the power button and the volume reduction button at the same time, at this time Apple's logo will appear, don't care, continue to press the double button and don't let go, the Apple logo will disappear again, at this time, release the power button, continue to keep the volume reduction key and don't let go, and keep pressing until the computer sends out the prompt sound "Ding Dong" connected to the mobile phone, which means that it has entered the DFU;

5. When the mobile phone enters the DFU, iTunes on the computer will pop up a prompt to connect to an iPhone, click "Confirm";

6. When you click "OK", iTunes will appear as shown in the following figure, this time the more critical step is coming, the shift key on the keyboard, and then click the "Restore iPhone" button;

Generally, there are several reasons for the automatic restart of the mobile phone, which can be self-checked.

1) Check whether there is a virus on your phone.

If the phone suddenly and frequently restarts, it is likely that it is a virus. You can use the mobile phone security guard to scan and disinfect the mobile phone first, and clean it up.

2) Uninstall some unnecessary software.

If there are too many mobile phone installers and too many software running at the same time, it is easy to fail to run and restart.

3) Software conflict issues.

If you think about whether you have installed or upgraded any software recently, it is often these software conflicts that cause the system to restart automatically, so you only need to uninstall the software that caused the conflict.

4) Factory reset.

If you can't be sure what software or plug-ins are causing your phone to restart frequently, you can choose to factory reset your phone and save the more important things on your phone before doing so.

5) There is a problem with the SIM card.

In addition to the internal software problems of the phone, the hardware problems of the mobile phone can also cause the phone to restart, and the SIM card error is a common hardware problem. Change a SIM card to the phone and see if there is a reboot to determine whether it is a SIM card problem.

6) Phone battery contact issues.

Poor contact of the mobile phone battery will also cause the mobile phone to automatically restart, and you can take it to the mobile phone repair office for consultation and help.
