6s not turning on

i was using my phone quite fine, and it died on me, when i place it to charge i realized that there was still back light i tried to turn it off but nothing happens so i did a force restart doing that it turned off but didn’t come back on so i left it to charge and realized that it was kind of hot around the front speaker area so i plugged it into my pc it said there was a problem with the iphone, so i did the restore and updated to lastest version after the restore there was just vibrations still no display now the vibrations have stopped and whenever i place it to charge the area around the front speaker still gets hot still no display i dont know what to, also that red light around the front speaker works
