EDIT: Also, I noticed that the phone is not powered off when it goes blank/unresponsive, just apparently can't see/use the screen/buttons. I tried calling my phone in its unresponsive state and it rang, but no display on the screen/button response. And iff I plug in the phone to charge, it makes the phone charging 'beep' tone, but again no screen display/buttons until I reset the phone by removing the battery and powering on again...
Well I think I FIXED my problem. It ended up being Google Maps causing the problem. I uninstalled Google Maps, turned the phone off, turned it back on, reinstalled google maps, and now it is all acting fine. Phone hasn't gone blank/unresponsive, battery is draining normally, and overall it seems faster than before the update now. Google Maps was the issue. I know others are having different problems, but for those getting the battery drain / blank screen; reinstall google maps.
