My wife's Droid had a standby battery life of about 1/3 of my droid, with all settings the same. Something was wrong with her phone. She got her droid at Best Buy, and I took her phone into the Verizon Store. After explaining the issue 2 or 3 times, and insisting that her phone battery life was different than mine, the Verizon Store gave her a new battery.
I'm willing to bet there are a fair amount of complaints on battery life, and the first step is to give the customer a new battery.
