iPhone 16 major issues

Hello,

I have owned iPhones since 2015, including the 6S Plus, 13 and most recently the 16—which will be here in less than a month. My iPhone 16 is heating up a lot, which is a terrible experience because I don't play games on it; I only watch YouTube or use it for regular calls or social networking. Unfortunately, my iPhone 16 is heating up a lot and shutting off automatically after less than a month it happened four or five times, and each time it stops working properly. It is quite annoying to manage with the new phone.
