Why won't my Android apps close when I shut them down?

Episode 1033 (12:24)

Andrew from Dayton, OH

Andrew has been noticing that when he shuts down Android apps, they still appear to be running when he goes into Manage Apps. Leo says on all mobile devices, there's no need for programs to actually shut down. On modern versions of Android, iOS, and even on Windows 8.1 or RT, apps don't necessarily close. The operating system just takes care of it on its own. When the user does something else, the OS will halt the CPU for that app, reclaim the memory, and eventually close it. It will still be in the "recent apps" section, though, but that's more for the user's convenience. Since it can manage apps automatically like this, it won't waste power or memory.
