When I first received my Droid Pro, it was about 70% charged, so I thought I just had to charge it to 100% and then use it. I did, and it would die after 8 hours of standby. I was wrong. I contacted Motorola, and they told me that when you first get your Droid Pro, you MUST charge it for 12-15 hours while it is off. Then the battery life is great! I purchased another Droid Pro Battery from Verizon, charged it for 12 hours, and now it lasts a long time. I know it is not the best feeling putting out another $40 sum dollars, however, it is worth it to get long battery life.
