My iPhone wifi gets disconnected when screen is locked

I saw that many had this issue and tried all the basic steps that were mentioned. It’s quite irritating to experience this issue as not always there is a possibility of using mobile data, as well as why should I keep my phone connected to a power? I have purchased MOBILE phone a couple of months ago for convenience not for additional headache (I didn’t have this issue on my previous iPhone). I was sure iPhone was the best but start to doubt really.

the problem still exists and when I lock the screen it switches to mobile data which drains the battery faster (in case the purpose of this function was to save battery).

iPhone 13 mini, iOS 16
