Hi and tnxs for reading. Other posts are talking about iPhone6 and 6 Plus screenshot size for iTunes Connect iPhone 6: 750 x 1334 pixels for hi-res portrait 1334 x 750 pixels f
Just ran into the same problem: I removed the status bar on all my screenshots (as I used to do it for the older iPhone models) only to learn that this does not work anymore for iPhone 6.
I looked at the screenshots of Apple's own apps (e. g. Pages). They do leave the status bar in, but it doesn't show a carrier and times is set to 9:41. This can be done by connecting the iPhone to a Mac and using it as camera input through Quicktime on Yosemite (like for app-previews).
