I'll give a more detailed review this weekend, but first my quick comment after owing the Note 5 for a few days. I've owned all three of the these phones now. Will explain that in more detail later.
The Note 5 feels like the iPhone 6 Plus and Nexus 6 had a baby together.
The N5 reminds me and feels like a 6 Plus in a good way, super high quality build, very good looking phone, jaw dropping beautiful display. But of course is running Android, but not the stock Android we all love, so this TW OS feels almost like a mix and mash of iOS9 + Android in a strange way.
I've rooted my Note 5, and am running a custom ROM, which is tweaked performance, better battery life, and debloated. I am also using Nova launcher, and a different icon theme, and the Material Dark theme from the Samsung store.
So my Note 5 now looks like a stock Nexus type phone, but with the added Touchwiz stuff like S-Pen apps, and actually some of the default apps are nicer than I expected. Like the dialer I prefer this TW Dialer more than Stock Android's. And just the way certain core apps run and operate I surprisingly like better than stock Android. When a phone call is over, the screen fades away after a few seconds back to the home screen, without me pressing the home button. Just little tweaks on TW that I am shocked seemed to be nicer than stock Android.
Battery life seems to be really good, easily on par with my tweaked Nexus 6, I am thinking it will be even better. This Note 5 will easily get 5h to 6h Screen On time for sure.
Wow, I ignore this forum for a few days and I come back to Z praising Samsung and Touchwiz of all things. World is going crazy I say. Almost as crazy as this weather we're having. I'm in Ontario CA, and even though it's 104 degrees outside, we just had a brutal thunderstorm roll through with 60 mph winds and quarter size hail. Makes no sense.
