When i bought my droid they told me to use the charger that came with the phone and that there was a special car charger for the droid. She also said if both of these are not used the majority of the time that it decreases the battery life. 1. Does anyone know if this is true or anything about this? 2. Is there such thing as a specific droid car charger? thanks in advance and sorry if this is a already a topic!
