Hello Tammy 78,

It sounds like your phone will not power on after it turned itself off unexpectedly. I would use this section of the following article to help you resolve the issue:

Will not turn on, will not turn on unless connected to power, or unexpected power off

1. Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
4. After at least 30 minutes, if:
   • The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
   • The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
   • Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
5. If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
   • If the display turns on, go to step 4.
   • If the display remains black, go to next step.
6. Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.

Thank you for using Apple Support Communities.

All the very best,
