I had the same issue, no power, black screen, couldn't turn it on. What is even stranger, is when I went to look for my iPhone in FindMy Device, it had indicated it had been off for 6 hours which would have been midnight at the change of the month from January to February. My alarm never went off on my phone this morning, obviously. I never received messages overnight, obviously. And if there would have been an emergency for me or from a family member trying to get in touch with me, I would have been screwed. Not sure what the bug is, Apple, but it's a bug that y'all need to get fixed and understood and fast. Missing an alarm to get up in the morning...not the worst possible thing that could happen but it did put a lot of stress on all of us this morning trying to get out the door. The good news and happy ending to the story is that I did the steps as listed, way deep in this forum (which by the way, I couldn't look up on my phone because it wouldn't turn on 🙄), however, the steps worked.
- Quick tap on volume up button
- Quick tap on volume down button
- Hold long side button down for a good minute until the Apple Symbol appears (I took my phone out of it's mag-safe case to do all this since it is easier to push the phone buttons and know you are pushing them when the phone is not in the case.)
I would be interested to know what exactly is causing this strange phenomenon in the new iPhones? Hoping my post helps others and helps Apple to know that is occurred to another person. Thank you.
