Closing but not quitting applications means that they are still running in the background, and thus drawing battery power. In order to improve battery life, be sure to quit unused apps.
In order to quit, and not just exit, iPad applications, double click the home button (the one on the face with the square on it). This should bring up a row of app icons along the bottom of the screen. Touch and hold one of the icons along this bottom row until it begins to wiggle and a little "-" (a minus sign) appears on each of these icons. When you then tap on the minus sign, this quits the application. When you've quit the applications you desire, simply tap anywhere else on the screen to return to the normal screen.Tags: mobile devices
