Auto off

[Stevies3]

Hi, I own an iPhone 4s. I seam to remmeber you can set how long before the screen (display) turns off. For some reason i can't find it and my iPhone screen stays on indefinitely now. The only way to turn it off is to hit the power button. This happpend ever since I upgraded to 5.1.1
