FS#5220 - LCD Brightness
The ability to dim the LCD to whatever brightness I want would not only save my eyes at night, it would also save battery I imagine. It can’t possibly be very hard, if the LCD can currently fade away, why can’t it just permanently be at a lower brightness setting.

Fading is done by PWM, i.e. fast switching between on and off state. This consumes even more power so I don't think this is a feasible option.
I love "It can't possibly be very hard" style requests. But yes, as was said, it requires to boost the CPU to dim the backlight, so having it dimmed would in all likelihood use more power than having it fully bright.
I think I remember that somebody said backlight fading doesn't need boosting on all players.
Anyhow it might still save power, as the backlight current is quite high (at least on ipod video).
But the main advantage would be the selectable brightness. The only thing I don't know is if backlight pwm could reduce lifetime if backlight is always-on.
Maybe I'll have a look at it, as the ability to reduce brightness was one of the main reasons, why I switched to rockbox.

Wow, thats a relatively fast response I think. Thanks a lot, Ralf!
