Knowing which applications to stop

I just got a used Nexus One and I see a lot of running services and applications. I'm wondering what negative impact there would be if I just started switching them off?

For example, obviously, I don't want to mess with "Calendar," but what about "Calendar Storage?" If I install Handcent SMS, do I still need the Messaging-related services/applications? Same for Media: if I install Winamp, do I still need those?


Calendar depends on Calendar Storage; Handcent still relies on the device's services for receiving messages; and I would guess that even if Winamp doesn't rely on Media, your wallpaper or notification sounds or something else does.

I would mostly leave these "System" services alone. If you have battery trouble, it's likely due to user-installed apps.

    Pretty sure that Winamp (and most other players) still use the device's Media database to save having to rescan everything themselves.
