Cleared RAM memory.
FYI, you can't do this. What you are doing (removing the app from the recently-used-task switcher, I'd assume) does not do what you think it does.
When you close an app by hitting the home button, if it isn't using one of the limited background APIs, the application is flushed from RAM within 60 seconds. Period. No exceptions.
Doing the "close from the task switcher" deletes the app's saved state file from the
flash storage, not RAM. The only exception is if the app is using a background API, like playing audio or using GPS, in which case it does also force-terminate the process and deletes the saved state file. Only iOS itself can clear RAM, and it does so very aggressively (even while apps are running if the device encounters a low-memory state, which is why some apps "crash" randomly on devices with lower amounts of RAM).
The task switcher on iOS is not a list of running apps. When you hit the home button, the apps terminate. The task switcher is just a list of most recently used apps.
That detail doesn't help with this, obviously, but I figured it was worth explaining, because there is a TON of misinformation out there. I've even been told the opposite by "Apple Geniuses" at the Apple Store before. They are
wrong.
