My expectation is that if I kill an App, that it's stopped. But I've found that some continue to have activity afterward, unless I reboot the phone.
This applies to iOS 6.1.
This doesn't make a lot of sense to me, so I wonder if someone can elaborate what's going on here - or whether there is some other way to handle it.
iPhone 4S, iOS 5.1.1, iOS 6
I know what multitasking is.
What I am referring to is when you kill off an App. That is, you hold down the icon on the switcher until they "jiggle" and then you exit them. One good reason for this is to preserve battery life.
In my case, as I explained, it appears that this doesn't actually always exit the application -- unless you reboot. This seems counter-intuititve, in the sense that the function itself is to exit (ie, stop) the App from running.

From that Support Page > These apps are not necessarily actively in use, open, or taking up system resources. They will instantly launch when you return to them.

What applications? You explained nothing. You make no mention or explain why you think applications are still running...

Read here > iOS: Understanding multitasking
Can you provide an example, including what you observe that makes you think the app is still running?
If you read through iOS App States and Multitasking, there are a few edge cases where iOS will restart a terminated app. For example, if an app has registered with the significant-change location service. "If the app starts this service and is then terminated, the system relaunches the app automatically when a new location becomes available."
What is your evidence that "killed" apps are still running?
If you're basing this on an app that shows "active" processes, these are unreliable. If your phone is jailbroken, all bets are off.
My phone is not jailbroken.
The apps I use, one of which is a social network app, sometimes sends me alerts that I have a message, long after I've killed off the application. The only way I can prevent that is to kill the app and reboot the phone. This seems to be either a bug, or a mis-behaving application. That's the evidence I have, which is clear to me.

Settings > Notifications > <app> > Notification center > Off... or manage the settings
Sounds like you have push notifications enabled.
I found those. But I'm still puzzled -- should the app still be running if I kill it off? Other apps I have don't seem to suffer this issue.
Thanks!
Technically it's not running, but it can still send you notifications. This can normally be turned off in the settings or from within the app itself.
I checked the app, no settings for this. I've had problems with this app in the past, other revisions, crashing the phone, too :-) Alas....
Apple Push Notification Service (APNS) notifications do not originate with the app itself. APNS notifications are submitted by the app developer's server infrastructure to Apple's APNS infrastructure. The APNS infrastructure then sends the notification to your iPhone. If your app is not active, iOS shows the notification message, not the app. If you respond affirmatively to the notification message, the app will then resume if suspended, start if terminated.
All apps that use APNS notifications work like this.
As several posters pointed out, you can control whether/how the notification message appears by twiddling the appropriate notification settings.
Did you carefully check the list of apps in Settings > Notifications > In Notification Center?
What app is it?
Push notifications are controlled entirely in the notifications section of the phone settings. They are "pushed" to the phone from an external server as a message that's linked to the app. The app isn't running. In fact, push notifications existed before iOS had any multitasking capability.
Apps still function, after killing them off?
