Yeah, on the iPhone they just kind of sit "inactive" if they're open. Exceptions would be facebook and twitter apps if you're a super heavy user maybe. But you aren't. Bluetooth will drain your battery, so if you don't use a Bluetooth device, turn the feature off in Settings. And I keep WiFi turned off unless i'm actually using it (at home or somewhere else). And then screen brightness; I keep mine fairly low (I figure I can always turn it up if I'm looking at something that's difficult to see).
