Ridiculous Phone Issue...?

[AC Question]

Okay, this just blew my mind, seriously. My phone can normally charge from 10% to 100% in less than two hours, but today it went from 65% to 70% OVERNIGHT. I don't know why this is happening, but while I was charging it during the day, the battery was literally dropping while I was trying to charge it. This has never happened before. How does it only charge 5% with 8 hours of time? I'm using the exact same charger and the exact same port. All I have on my phone is music. What is the correlation?

You may have a marginal connection on a cable going bad.
