My husband just replaced his Droid under warranty (got a new one from Verizon). He had many problems -- the phone would randomly dial people when it was just sitting on the desk, untouched and unbumped. That was annoying enough. Then it started sucking battery juice for no reason -- would go from 100% to zero sometimes, just sitting there, in an hour. I have had my Droid since December with no major troubles. He and I swapped batteries several times -- it was not the battery, but his phone. Finally his phone died and would not come back, period (could not charge it). I'm guessing there are just some lemons out there. I guess I'm lucky (knock wood) -- I've even dropped my phone 3 feet to pavement, twice (!), and it still works fine.
