I went for a drive today and put the Evo on the mount I built for my car, plugged it in to the radio and also in to the car charger. I have Slacker Radio set to leave the screen on as long as it is connected to power. My battery was probably about 95% and during the drive, it was charging and, while listening to Slacker, the screen stayed on. However, not long before I reached my destination, my battery got to 100%, the green LED was on, and the screen would follow the 30 second shut off that my phone is set to. I could no longer get Slacker to recognize when the phone was connected to power. Anyone have a similar experience? I'm hoping this was isolated to that one instance (some perfect storm of other settings, use, etc), but I have a feeling it isn't.
