It seems reasonable to assume that Apple, being a competent design house, did some research and listed "x hours of battery life for function y" on their market requirements docs. I guess I don't understand how meeting their design goals is a profound observation.

As far as battery life goes, the one feature I'm jealous of on Samsung phones is the extended battery life mode. Do they still do that? Anyone know if it's on other Android phones? I'm happy to compromise with a sleeker phone, a la Apple, if I can get some extra battery life while traveling.
