I've noticed the Droid2 has a little light next to it's USB port. That light only comes on when connected to a wall adapter. It will not light up when connected to a USB hub, computer port or any of several 12vdc car chargers I've tried. This is a big problem if you make heavy use of the phone while on a 12vdc source (like running trapster, gps, wifi and navigation while in the car). The battery isn't sufficient to keep the phone running and it won't pull enough juice through the charger to offset it. So I'm wondering whether the phone is making a mistake in how it's recognizing the different types of chargers. How does the phone know which type of source is connected? The API indicates it can tell AC vs USB. But it doesn't say HOW the answer is determine. And no, it doesn't appear to have a way to show an amperage value, just voltage and that's usually the same on either kind of source. So, WTF?
