How does everyone use multitasking?

The only time i close them with the double tap and hold is when i am using gps apps. Otherwise there is really no reason to do so

 

Apps that drain battery like GPS/Music are plainly obvious when running in the background (GPS has the little compass arrow top right, Music..well you can hear it).

Otherwise, manually killing apps does nothing (well it would, but the benefit is so small it wouldn't offset the usefulness or the time spent). I recently counted up on my iPhone 4 the number of apps in my tray, and I found 87. And the phone is as fast, and lasts as long.

 

I Close Them

I've had a real problem with battery life since upgrading my 3Gs to the 4.0 OS. It was obvious that some of the opened apps were running in the background, although I was finished with them. I've since become almost obsessive and compulsive about making sure any unneeded app is closed when I no longer need it. I'm not even sure that I'm saving much battery time, but I know my battery drains faster than before OS4. I'd much prefer a simpler solution to closing an app when I'm through and not having to track it down later on.

 

You can either disable multitasking altogether or use a combination of Backgrounder & Remove Recents app. I found a thread here somewhere & I'm loving my multitasking implementation now.

 

You can you the removebg app in cydia which can kill all app's left open. I recommend it

 

The two battery drainer apps I have seem to be Skype and Fring, so I often find myself killing those apps manually.

 

DL remove backgrounder. I'm assuming you have SBSettings already, if not, download that first.

 

This is correct. Apps that run in the background and drain your battery always have some type of indication.

That shouldn't be happening. If it is then an app or two you have has a bug. You should never have to manage your background apps.
