I bought a second battery and external battery charger for my Droid, but I've discovered that when I change batteries I have to actually plug the phone in for it to start back up - i.e. if I insert a fully charged battery, the phone won't turn on until I plug it in for a few seconds. Is this normal/by design? Same thing happens any time the battery comes out and it's really irritating - I actually just dropped the phone and the battery popped out, and now my droid won't turn on until I go home and plug it in for a second.
