Delete apps from your iPhone 5 if you have apps that you no longer wish to use. You can do so by simply deleting the app icon with these steps.
1. Navigate to the home screen that contains the icon for the application you wish to remove.
2. Tap and hold the icon for about 2 seconds until the icons wiggle. An X will also appear next to some of the apps.
3. Tap the X in the corner of the app.
4. Press the Home button to save your changes.
That’s all it takes to delete the app! The data and the program is completely removed from the iPhone 5 as soon as you remove the icon using this method.
