Wow what a difference! I'm sort of embarrassed to say that I waited so long to upgrade, because now I realize how crappy my iPhone 6 was! I used to be at 25% battery by 9 am with the 6...I've yet to use the whole iPhone X battery in one day! The processor speed/RAM is incredible...the Starbucks app and Snapchat used to crash my 6 but now don't hesitate at all when I use the apps. And of course, the camera is just friggin awesome on the X...what do you like most?
