It's a bit trickier than that. They won't run from USB power alone. The battery has to be replaced with a battery eliminator circuit.

If the phone is new enough, it may have an option to prevent the battery from fully charging. If it does, you can enable that and leave the battery in until it's completely worn out. That way you have a built in UPS.
