Sorry, there was a problem. Please try again later.The screen time is about the same as the older versions and I believe it's user adjustable. It doesn't seem a affect battery life since the new design has MUCH longer battery life. THe older versions lasted 6-8 hours on a charge, where I get about 20 hours per charge on the Sport. The screen size is somewhat moot since it only shows a scroll at the bottom fo the screen with the song info.
