Screen smash fixed/charging issue solved

Some time back I had my S4 screen cracked, but it wasn't heavily damaged so I left it. A short while after I had an issue with it saying it was constantly "charging" when it wasn't plugged in, with the LED lit and everything. It seemingly drained the battery more and made charging a longer job. I needed to get the screen fixed before getting this issue fixed under warranty, so I got that sorted. When the phone came back, the "charging" issue was solved, it worked regular again with none of the problems, regular charging and not draining. Any idea how this could be related to a cracked screen?

Could the crack have been slightly concave and putting pressure on the board?

It was a crack coming from the the top of the phone, going to the bottom left, just seemed odd that it's been fixed due to It, the phone didn't seem misshapen, but behind the screen who knows, I've not known anyone to have the constant "charging" issue though
