My phone won’t turn on after It overheated and won’t turn on at all

This morning, I woke up to my phone dead, I drag it to the side and check temp, it has partially heated but no to that extent. I decided to put it on the charger, which when I found out that’s how it was heated and then I decided to simple let it charge using a different charger and after an hour, I tried turning it on, but no screen or nothing. Then I did the same process, except I tried a factory reset. Didn’t work. What do I do now.
