...The most important features to me are battery life and camera performance (I'll be taking some pictures for the paper with the phone). It's interesting that some people in this thread seem to indicate that the Note 4's battery life may have improved after getting Lollipop, but a lot of other things I've read indicate that it gets worse after the update. Anyway, that's one thing that makes me a bit nervous about getting a Note 4. If it makes any difference, I'd be using it on Verizon.
It seems that those that did the factory reset after the update have better battery life, and those that refuse to do the factory reset after the update seem to have battery problems.
That is a generalization, and not applicable in 100 percent of the cases.
However, supposedly if you give the phone enough time, it will optimize itself and the battery life will improve, if you are one of those that decides they do not want to do the reset for whatever reason.
The other consideration is that some people have had their note 4 long enough that the additional heavy use is starting to deteriorate their batteries.
After 6 months of heavy use all batteries start to deteriorate, & a lot of people are not taking that into account. Want proof? Just ask an iPhone user!
Just my two cents worth.
My battery life was very good before and seems to be even a little bit better afterwards, but my battery is fairly new.
Unfortunately, as far as I can tell, every single comment about improved or degraded battery life is subjective. There are no accurate before-and-after benchmarks that I'm aware of.
However, I believe that most of the people on this forum are smart enough to have a good gut feel about what they are experiencing, and albeit subjective, I do believe that for people who have not done the factory reset, the battery life is horribly degraded.
The camera is great, much better than on the note 3.
FYI, I am a Verizon user as well.
It sounds like you should not consider any type of sealed phone, as you will likely be hating it after about 6 months when your battery won't hold a charge anymore.
