Here's the low down. I'm using UDv9.0 with adamz medium volt 1.0ghz kernel, OC'd at 1 ghz. I took a trip to St. Petersburg, FL from my home town, which is about 1 hour and 30 mins away. When I left the house, my phone was fully charged at 100% and I plugged my phone into the car charger while I was in my drive way. (*I also launched google maps navigation at the same time.*) So by the time I made it to my destination, my battery was down to 60%! How could that be, when my phone was charging the entire time? I thought that when the phone is charging and it's in use, that the battery wouldn't drain. The charger was from Verizon, with the Verizon logo on it, so I believe it's a pretty decent charger. I bought it for my Storm2 and once I switched to the Droid, I continued to use it since it was the same hook up. So my question is, what was the problem? The car charger, the rom, or the kernel? Or is the drainage something that is suppose to happen with navigation, regardless if it's connected to a charger? Are there certain car chargers that put out more power? If not, what's the fix for this if there is one? Thanks for your reply's in advance.
