I purchased my Droid last Monday (3/15). Everything was working great and I downloaded several apps throughout the week. On Friday I ended up sync'ing my contacts to my Facebook account so it updated my contact list to include all my Facebook friends. I also sync'd an app called EboBirthdays to my Facebook and then sync'd the Ebo App to my calendar. That evening my fully charged battery died over night. I charged it back up and then it died again 2 hours later. It has only been holding a charge for about 2-3 hours ever since Saturday morning. I have a battery app that shows the phone does get a full charge. I also have a tracking app that shows that the battery charges all the way but then starts taking massive hits of battery use. When I check Settings>About Phone>Battery Use it tells me that 70-80% of my battery is being used by my calendar. I have uninstalled EboBirthday and used my App Killer countless number of times to kill all Apps running but my battery still only lasts 2-3 hours. I called Motorola and they were not any help. They told me I needed to reset my entire phone back to factory settings and if that didn't work to get a new battery. I am trying to avoid both of those and I really do not think that it is the battery. Any suggestions? PLEASE HELP!
