We are now on the general settings tab & what we are going to do is click on the usage tab at the top of the page.

This is the usage area of your iPhone it basically tells you how much memory your apps are using. We are not interested in this just scroll down the page to the bottom.

At the bottom of the page you will see a tab called battery percentage just swipe left over the ON button to the right of it.

Its now OFF and even more battery is saved. To turn it back on just swipe right over the OFF button to the right of the Push icon. Now exit back to the home screen.

The home screen. Im going to show the final thing to keep your iPhone running with great battery time. You need to double click your home button. Thats the one at the bottom of your phone.

When you double tap the home button a list of all the programs still running pops up this also contributes to battery life loss. They may not be in use but they are still running in the background.

So to remove the unused apps simple hold your finger over one of them and they will shake with a little red circle in the top left corner of each one. Click on each circle to shut them down.

Once you have done that the box they were in is now empty. To continue with normal usage just click any where on the screen. Perform this shut down daily for best results.
