After I installed the last iOS 7 version because I had beta 1,2,3,4,5,6 (the last one) I still have problems with my phone battery so that´s the main reason I insist so much with save your battery life.
How Forcing Closing Works in iOS 7
iOS 7’s new method to completely exit your running apps (and prevent them from running in the background) is even easier than iOS 6’s, although it isn’t immediately obvious.
All you have to do is double tap the home button to bring up the multi-tasking view, then swipe up on the screenshot of the app you want to exit. The app will fly off the screen, and release its resources to the OS.
Easy, right? Don’t feel bad if you couldn’t figure it out. While many of the new features will be familiar to veteran iOS users, some aren’t immediately obvious. One of the first things that I had difficulty figuring out was how to force-quit my apps.
Pro-Tip: Close Multiple Background Apps at Once
Although there isn’t currently a way to completely exit all your background apps at once in iOS 7, you can use multiple fingers to swipe and close up to three apps up at once. Repeating the gesture multiple times will make quitting everything quick and easy.
Previous Versions of iOS
With previous versions of iOS (from 4-6), all you had to do was double tap the home button, tap and hold on the app you wanted to close and tap on the red icon that would appear. Now, tapping and holding the icons in the multi-tasking bar does nothing.
Don´t forget you still have to learn lot´s of tricks about you new iOS 7.
