This morning on the way in to work I was listening to KFI out of Los Angeles and right before the top of the hour newscast listened as Rush Limbaugh stated that although he may well be mocked in the electronic press, he swears when his iPhone is completely charged he turns it completely off after unplugging it. Leaves it off for a minute or two and then powers it back on. Says this simple trick gives him more than enough battery life to work the full day whereas before he wouldn't last till mid-afternoon. What is your take? I think it's worth trying, but I remain a bit skeptical.
