While the iPhone seems like a wonderful gadget, it sure sucks down the power. Here are a few tips for making a battery charge last longer:

- Turn down the brightness of the screen.
- If you don’t plan on using Wi-Fi or Bluetooth anytime soon, turn them off.
- Don’t check your e-mail every five minutes!
- Make sure auto-lock is on, so that the screen will be automatically dimmed after an interval of time.
