I to came from the Note 7 although I did not have it long enough to be a die hard fan. The phone was growing on me. I now have a silver 256GB 7+. I got it after I became a Pixel XL refugee. I just started going to every phone store and found this returned 7+ unused, the lady decided she wanted a blk phone.
It is an expensive switch with buying accessories and extra cables, new Apps but I intend to keep the phone for the long haul. Or at least till 256GB is full LOL. What sold me was the widget page in iOS 10, I am carefully searching for apps with widgets I want displayed.
There is a good youtube video "iOS 10 hidden features" that is helpful plus many others. iMessage has a ton of new features I am still trying to figure out and this video helps that.
My battery life has been great but as I load more apps it does use more battery I think.
Any other tips or tricks is appreciated!
