Dropped and is completely dead

So i was using my iPhone 6 when cleaning out the fan of my Macbook Pro as a light source. I was sitting in my bed and it slipped of the side of the bed. It dropped and the flashlight and screen immediately switched off. I opened up the phone to check if it was just the screen that had disconnected, i also checked the battery. My phone does not respond to home+power, the mute switch, turning on or charging. I also tried to get a software to detect the phone when connected but even that didnt pick it up. I have no idea what to do. Does anyone know what to do?

NOTE: Phone had a broken screen previously
