Prevent iPhone to sleep

Question

I using accelerometer in my app and i'm using [UIApplication sharedApplication].idleTimerDisabled = YES; to prevent the device to sleep. It works fine, but this way the screen is always on full bright, there is a way to prevent the device to sleep and keep the energy economy mode on? When idleTimerDisabled is stetted to NO the device enter in the energy economy mode before sleep, i just want to prevent the device to sleep and keep the energy economy. There is a way to do that?

This is on the border of Apple guidelines and your app may be rejected for doing this without very good reason. — Registered User, Jul 14 '12 at 18:13

There's a property of UIScreen instances, brightness, that is likely what you want. Check out the documentation of UIScreen's brightness property here.

Try:

[[UIScreen mainScreen] setBrightness: 0.3];

NOTE: As I was posting, DarkXphenomenon posted a link to an SO question whose asker gave the exact same solution. DarkXphenomenon is quick on the draw.
