iPhone 15 pro max

Recently, I just purchased the iPhone 15 promax and I also experience the screen going black just today 10/20/2023. I had it on the original charger and when I woke up my phone screen was completely black. I panicked for a moment, but I also Google how to restore my screen and it worked however, is this going to be an ongoing issue. I also hope they can fix it because I use my phone for work.
