Turn off screen but postpone screen lock for a set time.

[Matt Hieter]

Is there an app thas will allow me to trun off the screen (hit the power button) to save battery power but not lock the screen until the time that I have set in the Lock Screen settings (5 minutes)?

Even better then an app, there's a setting.

Settings->Lock Screen->Uncheck Lock screen instantly with power button
