Any way to "close all" open Apps with multitasking?

So I feel like when I have a lot of open Apps, I'm unnecessarily using battery life. I then have to close all open Apps individually. Is there any way to kill all open Apps with one punch?

Also, are open Apps draining battery life in the background?

I believe if you power off the phone, it will reset the apps.

In 90% of cases, no they are not. They only use power if they are playing audio, using the GPS, using VOIP, or completing a task (for 10 minutes max).

Other than these few cases, it probably uses more battery to restart the phone than it does to just leave the apps in the background. In fact in most cases it probably uses less battery to resume a suspended app than it does to start it fresh after being quit.

Good to know. Maybe my paranoia around open Apps will cease based on this info.:p

People have to get over the idea of that "Recent Apps" list is a task manager or list of running apps. It's not. Some of them may still be running--and if so, it's because the developer intended them to and specifically coded against the necessary API.

Run-of-the mill apps are NOT running just because you see them in that list.

Unfortunately, there is no easy way to know that a particular app is still using resources or not.

Hopefully this thread will have the same effect on me. So far, I've been insanely anal about closing stuff up after I'm done using it. My home button is gonna fall off from double clicking it so much. lol.
