Hi and welcome to the iPhone forums. I deleted your duplicate post as it is against forum rules. I makes it hard for members to follow and creates confusion. Thanks!
My iPhone6 seems to be much better in direct sunlight than my iPhone 5s, but I don't have it with me anymore to compare. Can't comment on the plus though
That's great to hear. This spring, trying to recover from the long cold Midwest winter, I spent a lot of time poolside in Vegas and needed to give someone some info I had on the iphone, tried to read it evendYs while.under a towel and it was still too bright. It was frustrating to have to change location just to see the phone screen.
