Lock Screen Wakes/Lights Up with ANY Notification

A

AC Question

I've been searching and searching and haven't found the answer. Just recently my S4 has been doing this. Whenever my phone is locked and the screen is dark, ANY notification, text/FB/Skype/App Store/anything - shows up in my notification bar - my screen lights up. I went into settings->Sounds and Notifications->Notification While Locked and Selected Do Not Show Notifications - all that did was make the screen light up when I get the notification - but the notification isn't visible so I just see my clock/date. This just started happening and has been draining my battery significantly. Other forum posts talk about text messages doing this, but again - ANY notification triggers the screen to light up. I haven't changed anything, haven't dled any new apps, no update - nothing. This came out of nowhere.
