Pretty much the same thing in what way? Size?
I went from the 6s Plus to the 8 Plus... been using it for 48 hours now and the differences to me are night and day.
Biggest things I've noticed?
1) Battery life - My 6s Plus couldn't make it a half day at work streaming music and/or video without needing a charge... I ran the 8 Plus all day today... still above 50%.
2) Display - The difference is obvious... colors are bright
3) Camera/Photos - very sharp
4) Sound - Is this really my first go at stereo speakers? The sound is amazing!
5) Speed - blazing
6) Touch ID - hasn't failed yet
Don't miss the lack of a headphone jack. I use bluetooth headsets. No complaints... amazing phone. Verizon gave me $275 for my old one... can't complain.
