I haven't had an issue with my S4's battery life until sometime within the last 5 days. The battery is dead in less than 12 hours with very light usage. When I go into the battery stats it shows "Andoid OS" using the most battery far beyond anything else. Even the screen! What's going on?

Check out Gsam Battery Moniter (https://play.google.com/store/apps/details?id=com.gsamlabs.bbm&hl=en)
It will tell you exactly what is using the juice. Lets you track down what app is the issue.
Also check your screen timeout, there are times that you screen will turn on (like a text message) and if you are set higher than 30 seconds, it will keep your screen on and drain the heck out of your battery
Settings --> Device --> Display --> Screen timeout

Yes. Many times. Even did a hard reboot by pulling out the battery while it was on.
What's your signal like where you are?
