Ok, this may be a stretch but is it possible for more than one instance of the OS to be running at the same time? This is why I think it's happening. When my alarm goes off I have to dismiss it 3 times. Many times in notifications, I receive multiple, duplicate notifications. Sometimes when texting I'm told I sent the text 3 times. My battery will drain to around 50% in an hour and a half even if not being used and battery info will show 1.5 hours of battery remaining. That is about 3x normal battery drain. It may just be coincidence but three is the common denominator. Any thoughts?
