I haven't seen this issue since my Note was new but... since the Security Update, it's back! I had an issue (and several other folks did as well) where while in standby overnight, my Note generally uses about 6% or 7% of it's battery. That's every single night, like clock work. But back then, once or twice a week, with no rhyme nor reason, I'd wake up to 84% remaining - could never really get a handle on what was causing it either. The next Security Update cured it, never to happen again (10 months) until now - it's back! Anyone else noticed any battery differences since this most recent patch? I've cleared cache already too... it's not annoying enough for me to do a Factory Reset! I'll just wait for the August Security Update and see if that solves it, provided that happens with the Note 9 Launch coming!
