If you are using up the battery of your device at an amazing rate, you may have too many apps open that bogs down your device and slows it down. To fix this, simply double click on the home button on your iPhone or iPad.
You will see a series of all your open apps. Scroll through them by swiping left or right and remove those not in use by placing your finger over the unwanted app page and swiping upwards. You do not need to worry about losing data if you removed a page by mistake.
