OK, if you are anything like me, you probably have never read nor have any idea where your iPhone 4 instructions are (come on, I’m a guy, enough said), but one thing that has frustrated me to death was how to close background applications on the iPhone 4, sucking the little battery life out of the device.
So, allow me to spare you the potential loss of speed and battery life your iPhone 4 may suffer in the future from tons of open apps.
In order to have the best performance on your iPhone 4, make sure to close the apps you don’t need in the background. To do this, simply follow these instructions:
1. Double tap your home button. When you double tap the home button your multitask view will appear.
2. Tap and hold the app icon you want to close, just as you would on the home screen to rearrange icons or delete an app.
3. Hold the app icon until a red “-” button appears in the left-hand corner of the icon.
4. To close the app, tap on the red button in the corner of the app you want to close. What I do as well is to close ALL of the apps I am not using. You will find that nearly every app you have ever opened will be open at this point (ah, no wonder your battery runs out so quickly huh?).
Now those battery sucking, memory and speed eating apps will actually be closed on your iPhone 4 (yea!).
Hope this helps, let me know by leaving a comment below if it did!

Here is a a great app for conserving battery life:
BATTERY DOCTOR (get the full version for $0.99)

I have used it for a long time now
Sorry to disappoint you, but that will have no effect at all on your battery life. Those apps are not actually running. Yes, it is good to clear out all your apps now and then but the only way to improve your battery life is to turn off things that use system services which do run in the background:
Turn off Ping
Turn off notifications from apps that you don’t want them from
Turn off bluetooth
Turn off wifi if you are not in a place where you are using it
Turn off 3G if you are not using it
Turn off location services for apps that you don’t need them for.
(and you probably want to turn off location based iAds too)
Trim down what spotlight will search for – this stops it indexing so much and so improves battery
Any of these (and more), but not killing apps I’m afraid, that does nothing
Thanks for the added info Marvin!
