iPhone 101

I been using an iPhone since its induction in 2007 and I'm just now finding this out. Ever wonder why your battery life sucks? Guess what, it has nothing to do with AT&T. Tried all the switch to wifi, lower your screen brightness and turn off your location tricks to no avail?? Well check this one out. Double click your home button. After this you'll notice some icons appear at the bottom of the screen. Next hold one of those icons until it starts to shake. Do you see it? That red minus sign in the top corner? That means that app has been running for god knows how long! Clear out everything that has that minus sign next to it and you'll notice a major difference! As Kobe Bryant would say Your Welcome.
