Before the update to Lollipop, I adored my Note 4. Everything worked perfectly, I had no complaints. I am a power user, I work for a technology company, I know how to mess with my phone, and I specifically bought this phone as something I could do my job on when I wasn't in the office. I would unplug my phone at 6 am, use it normally until 10:30-11 PM, and would plug it in before bedtime with some 20% left on the battery. Since the update has gone through, I'm lucky if I can get 6 hours of battery life out of it, and that's with me working during the day and not really messing with it other than to check text messages, see alerts, etc. It just sits on my desk and steadily drains. I have to charge it at least partway during the day, and then charge it some more when I get home so I can actually use it. It also glitches in that it abruptly hangs on a screen or an application and I have to hit the power button or the home button several times to get it to react, I click on something and have to wait for up to 20 seconds for it to react, I have to force close apps to get functionality back, I randomly drop calls in an area where I've never had an issue before.
I've done a lot of research on the issue, I've factory reset it 3 x's, I've cleared the cache partition weekly, but I am not going to go through and start disabling all of the features on the phone (wifi, bluetooth, gps) that I specifically bought the phone for. I already tell people not to do the update, but I would hope there would be some kind of fix to correct these issues or even allow people to reset back to the true factory condition, pre-lollipop update.
My 2 cents

I would love that link if you could sneak it by
