I've had the Note 4 (Verizon) a few weeks now (not quite a month). My battery drain totally depends on a) actual activity on my part, b) background services I have running. One sure drain? Having location on does drain a bit more, and having high accuracy location on drains a LOT. Significantly so. I typically leave my location on power saving mode, I have the phone itself set to power saving mode, and I have Bluetooth always on. My brightness is set to auto. Smart stay is off.
On most days, I unplug the phone from the charger at 6 AM and plug it back in between 9 and 10 PM. The phone usually is 50% battery or more. On days with very heavy usage, it might dip lower into the 20%-35% range, but that's with VERY heavy usage. I have been able to go a full 2 days of light to medium usage without a recharge (just 2 days ago, in fact). If you use the camera, use high accuracy location, use smart stay (which uses front facing camera to try to determine if you're looking at the screen in order to KEEP THE PHONE "ON" automatically), etc., you WILL see more drain.
Sorry, no pretty charts here. Just anecdotal, real world metrics captured by me, as I have been watching this Note 4 battery since getting it. My previous phone (Verizon Galaxy S3) was AWFUL even though it used almost identical configuration, minus Bluetooth, which was only turned on when actually needed, so I had a vested interest in battery life.
I've been very impressed with the Note 4's battery so far.
