Gotta agree with this.
Even though I am a diehard Note fan (and I will get the 4 sometime), the Plus interests me, esp if I can get a 2nd phone through work. However, I prefer forum users' experiences that take place over time to a lab. My Note 3 has very good battery life, but if I need more, I have a spare. With the iPhones not having replaceable batteries, the battery life is more important to know. In a month or so, solid results should be posted.
This time, the Note 4 actually looks better than the new iPhones. Actually, with the colored metal sides, it looks great. Can't wait.
