ALL,
From any screen press and HOLD the Home Button until the Task Manager appears. Then touch the words Task Manager. At the top of the next screen you will now see 4 choices. Lightly slide your finger from right to left and drag the entire 4 choices to the left and you will see Help...touch it.
Wa-La, there it is, Tips to Extend Battery Life.
Hope you like it and that it helps you. I particularly like tips 1 and 4, how about you.
