Question about data connection.

[ImBatman]

Ok, if you check your email every 30 mins or so, does the connection stay connected? I have the problem that when I set my gmail account to automatically check my email every so often, I look down a couple hours later and still see my connection "on" of that the "data connection" is still live. Does that drain the battery in the long run or do you just leave it on and it happens? I usually turn it off when I see it active and have now changed my gmail accounts not to check every 1hr but back to "manual" due to the active connection last long periods of time.
