Save Battery Power

It’s no fun when your iPhone runs out of juice. If you notice it’s getting low, and you aren’t going to have a chance to plug in any time soon, here’s what you can do: turn off Wi-Fi, Bluetooth, or 3G. If you aren’t using one or two of these, they’re just wasting power. Also, turn the LCD brightness down a notch or two. You’d be surprised how much power it uses.
