Default Phone only charging while turned off.

This started tonight. My phone was dying while sitting on the charger. I mostly use wireless chargers, and sometimes they are a bit finicky, so I thought nothing of it and just plugged it into a backup plugin charger. It was still dying. Pretty quickly too.

I turned my phone off for like 10 minutes and left it plugged in, and it went from 20 to 29. Then started dropping again once it was on.

I am on a stock 4.4.3 rom, rooted.

Any ideas here?
