app to determine cpu sleep prevention?

[tuftslax]

So I'm pretty sure that my phone isn't "sleeping"as much as it should and is running longer than it has to.does anyone know a good way to determine if there is an app preventing it from going to sleep besides trial and error?

Thanks

Are you rooted and using SetCPU? With SetCPU you can set the device to underclock when in standby if battery savings are what you are after.
