So far impressions.
Battery is doing well as I've been messing with the device and it's certainly an improvement on my edge by a vast amount. I'd get 3-3.5 SOT on my edge.
I'm at 56% battery and at 2hr 55mins SOT on the Note 5.
At 50% 3hr 23mins SOT
I find the extra screen real estate better than the S6 edge but still think the edge is a far prettier phone. I'm actually set to Amoled Photograph mode for colour balance and I'm liking the look.
Camera still excellent but no difference to the edge really as we all know.
Important for me = Ram Managment. Ok whilst its still not as good as my stock devices with 3gb like the Nexus 6, it's more like the peformance of my Motorola x 2014; but importantly it's far better than my edge. It's keeping my main apps in memory much longer and it's far less interfering than the ram management on the edge. Without shadow of doubt there is still work that can be done here but the extra 1gb is helping. It makes it far far less an infuriating intrusion when it does reload.
I'll post some drawing samples when I've played a bit more
