This is my first full day of using my Galaxy S8+ on Verizon, and I must say that I'm quite impressed. I came from an LG G4, which was okay in terms of performance, but it had horrible battery life and it would do dumb things like the screen turning on by itself and having a mind of its own, scrolls registering as taps, and Bluetooth deciding not to work at times until rebooting the phone.
I'm impressed with how fast the S8+ is, and I'm loving the AOD. It's feels good in the hands too. My first impressions on battery life are excellent, probably the best I've seen in any smartphone I've used:
This is after streaming several long videos (~45 minutes), some YouTube, Facebook, and web browsing, as well as a couple short phone calls. Full HD and 30% brightness.
So far, my only negative about the phone is how easily you can muffle the sound by covering the speaker. Other than that, this phone is a beast!
