So does anyone knowing there is an App that kills/turns off all other Apps that run in the background and drain battery life. Oh, and yes I do know how to hit the home screen button & do it manually. Thanks
1. Double tap your home button. When you double tap the home button your multitask view will appear.
2. Tap and hold the app icon you want to close, just as you would on the home screen to rearrange icons or delete an app.
3. Hold the app icon until a red “-” button appears in the left-hand corner of the icon.
4. To close the app, tap on the red button in the corner of the app you want to close.
Now your app will actually be closed and will free some of that memory on your iPhone and save your battery life
Nope. An app like that cannot be in the Apple Appstore because it would operate outside the sandbox that Apple tells devs. Apps can only control themself.
