Q: I try to charge my iPhone as often as I can, but I find that on long work days, it's dead before I get home. Do I need to start carrying a charger with me wherever I go?

A: Consumers have been complaining about the battery life of electronics for as long as mobile devices have been in widespread use. The iPhone is no exception.

The thing to remember is the most obvious: If it looks like it takes up a lot of battery, it probably does. When you know that you're not going to have access to a charger for several hours, don't download new applications or play games. And, for long road trips, it's smart to invest in a charger for the car; the Belkin model will only run you $24.95 and is available at Apple's online store.

Here are a handful of other quick tips and tricks that will help keep your battery going longer:

  • Adjust the brightness of your screen: The screen takes up a lot of power. Play around with different levels to see if you need to keep it at 100 percent.
  • Turn on the auto-lock function: If you set your phone to auto-lock after only a minute, you won't need to remember to manually turn off your screen when not in use.
  • Turn off the vibrate function: When you're playing games (which you shouldn't be doing anyway if you're looking to keep your battery alive for a long time), the vibrate function is terrible for battery life.
  • Fetch new data less often: Temporarily set your phone so that it retrieves new email¬†manually, only when you tell it to. Retrieving data every 15 minutes or even hourly will contribute to battery drain.
  • Turn off push notifications: They can be incredibly helpful, but if you don't need them, turn them off.
