Holly Cats, Dogs, Cows, and Pigs

Had the S6 edge and the S7 edge. Neither lasted long due to poor battery life and lag. Almost gave up on Samsung but took a flyer on the S8+.

Agree with OP entirely - WOW! Zero lag, great battery life, buttery smooth. Definitely a few niggles that they could fix (more responsive fingerprint scanner, more reliable Iris detection, kill that annoying Bixby button that I hit 20 times a day accidentally!) but all in all, VERY happy with this phone!
