Reasons why the Apple phone can't turn on:

1. There is no electricity. 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 trying to turn it on.

2. Software malfunction. 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 button + power button on the home screen of the mobile phone at the same time until the screen is lit up and there is a display.

3. System crash. If none of the above solutions work, and you see an iTunes connection screen on your iPhone's screen, it means that your phone has entered recovery mode at this time. When this happens, the only way to do this is to restore the system for your phone.

Connect your phone with the computer with a data cable, press and hold the home button and the power button at the same time for 10 seconds, then release the power button and continue to press and hold the home button for 5 seconds, if you see the connection to iTunes, it is a failure, and you have to start again. If the screen doesn't light up after these 2 steps, you will enter DFU recovery mode, and then you can use iTunes to restore your iPhone, or use a third-party flashing software to reflash your iPhone.
