I got a Note 4 two weeks ago and it's been having some serious battery drain. I've contacted Samsung and asked about it and they said it was normal, but looking at reviews and other threads, I can definitively say that it isn't. I've been to a local Best Buy where they reset the Android system on my phone to try to fix it, but that isn't helping too much. I tried T-Mobile to see if they could hook me up with a different battery to see if that was the issue, but they didn't have any and I have no choice but to buy another battery (not happening) or send it to Samsung and get a new one in two weeks or so.
I keep my brightness at about 10% or so and power saving mode is always on. I kept it on Safe mode to see if apps and app-related background services were a factor, but it doesn't seem so.
