I noticed that the default email program that comes preinstalled does not disconnect from the network after downloading. Instead, the grey arrows remain in the connection icon.

I would imagine that this wastes battery power? I have switched to Snappermail which automatically disconnects after downloading. However, it must reconnect everytime it downloads new mail.

Anyone have any insight into whether this is helping to conserve battery life? Or, is this wasting more by having to reconnect each time I download.
