I switched from the galaxy s6 edge + when the battery wouldn't even last half the day, I'm a really heavy user and my work email good messaging takes up a lot but the battery on the 7+ lasts the whole day. I wish the dialer would predict based on names and the alternative keyboards don't work on all the apps but those are quibbles
Went from S7edge to 7 plus on April 15th. Had an iPhone years ago but LG and Samsung for at least 5-6 years. Really like the Google apps on the iPhone. Scrolling is so nice on iPhone compared to Samsung. Battery is looking to be a vast improvement over past iPhones and camera is outstanding in every way.
