What don't you get? There is no reason to close them. They go to a cached background process and don't use any battery/resources. They are loaded into ram so they open faster when you need them. Eventually it will be cleared as new room is needed for other apps.....
what part of my wanting to control the apps did you not get ? It's mine and it will be under my control and perform the way I decide it will.
why do I need to tell you that apps that do not have exit/close buttons are lazy programming ? When I want an app to close, it had better close - and who in the pc / Linux world wound accept any app that reopened after being closed to perform ANY operation ? have you never checked to see if an Android app you have closed, or for that matter forced shutdown and found that it reopened by itself and was running 1 or more processes ? The type of process or operation does not matter but the fact that it EXISTS in that state DOES, and I have found MANY apps that open after I close them and certainly many that stay open with no exit/close button. Am I too stupid to know when I am done with an app ?
what part of poor performance on the Nexus 7 (or any comparable product with this type of RAM) with simultaneous RAM I/O do you not understand ? Processes like background syncing or downloading updates slow I/O performance of foreground apps and can make the device crawl.
AnandTech - The Google Nexus 7 Review and for that matter DRAIN BATTERY LIFE which was the point of this whole discussion. Get It ?
I ALWAYS disable PC "auto"-windows update because it decides to start massive download operations whenever it wants (generally when I want to do something requiring max performance, LOL)
I ALWAYS will run app closers for the same reasons and those mentioned above. There is no significant downside to my controlling my device and significant downside to letting wild wild west days on MY computer.
