The IPhone itself is unstable, resulting in a black screen. This black screen can be attributed to unstable automatic shutdown. It is because of the poor quality of the mobile phone that it is turned off for no reason. Because there is nothing wrong with the hardware, just press and hold the power button and wait for it to start. DFU mode is a mode that iTunes can recover when Apple system fails to open.

However, there is nothing wrong with your mobile phone. I thought it was a mobile phone fault, because you mistakenly entered DFU mode, which is actually easy to solve. Just hold down the power button and the Home button at the same time and wait for your iPhone to respond, usually 10 second.
