All I can say is I love the big iPhone. I like the big screen, and the and absolutely love its battery life! I would get the iPhone 6s Plus in a heartbeat but I can't afford it. I currently have a 5s and I think a jump to the standard size 6s will be a good jump. I know the 6s features 4k video recording, which is cool but it isn't that important to me, Either is the 3D touch option, but he new "s" models do come with the A9 chip and 2gb of ram which supposedly makes a big difference in phone speed and performance. So the question is... should I upgrade my 5s to the iPhone 6 plus for the size and battery life? Or should I upgrade to the standard size 6s for the speed and performance.
