Leaving Apps Open
What are thoughts on leaving apps open for iPad and iPhone?
When you open an app and then go back to home, you can slide to the right from your home screen to see open existing apps; then you can slide up to close it.
Does having several apps open that you use everyday, have any affect on your battery? Does it take more battery to just slide to the right from home page and select the app or does it take more battery to close each of the apps with a double click on home button and then open them when you need it again ?
