My apple 14 pro screen is black and the phone will not turn on
My phone was working last night perfectly fine. I must have looked at it when I was half asleep. When I woke up this morning, I noticed the phone was on the floor and screen was black and the phone was not on or working. I have tried to hold down the power on button and volume button to see if my phone was turned off as well as plug in my phone to see if the battery was done. However, it was at 77% last night when I had fallen asleep. I am trying to use my phone and I am not able to do so.
Any help or advice of what to do would be greatly appreciated. My phone is definitely needed and it not working right now is an inconvenience.
iPhone 14 Pro, iOS 16
