These days, cell phones can come with flash cameras, video cameras, music players, games and other toys beyond the usual directories, calendars and alarm clocks. Tech industry insider Marty Winston brings up an important point about these added features.

The more stunts you have a phone do, the faster you're likely to drain its battery. That means less talk time, less standby time and a chance that when you really need to make a call you'll be out of time. When you think about a new phone, think about how long it's away from a charger.

Added cell phone features can also add to the price of the phone, and maybe to the price of your service. Shop carefully.
