Back in the day i used to plug my ipod into a car charger when it was dead and i needed it in the car but never used it otherwise as i felt it was harmful to the long term battery life to always be plugged in. Nowadays i have an ipod dock adapter in my new Eclipse just to listen to the ipod and theres no way to stop it from charging while it played. Since this ipod is almost 3 years old and i only use it in the car i don't care what harm i do to the battery so much but with an iPhone this scares me as ill need that for long periods of time without being plugged in. Does anyone else think these car dock audio adapters are a bad idea and should have a no charge option? I'm planing on gettin a plain aux adapter just for the iPhone.
