why does my screen stay lit up while charging

I have an HTC M8. When I charge it, it stays lit up the entire time. (Usually all night) How can I make it go black?

Re: why does my screen stay lit up while charging

I don't own this phone in particular, but I noticed on my Note Edge and G5 that there is an option to keep the screen always on while charging. You should be able to search within your phone settings menu for "screen always on" or something along those lines, and switch it off!
