I've had my Note 4 about 10 months or so. I could normally go from 6am to 9pm and still have at 25% battery left. General use. With in the last month or so it has been a hog on battery. None of my setting have changed. I had Verizon look at it they said everything is ok. They were going to order My a new battery but there on backorder. Also one of my coworkers has the same phone and there's is now a battery hog also.
