As most of you may know, iPod's new 1.2 updater for the iPod 5G lets you adjust the backlight, preferably to a low output. Shockingly enough, people at iLounge have tested the battery life with the backlight to is lowest while watching video, and instead of around 2 hours, they got around 3 hours and 30 minutes.

Rockbox does not need video support; we're here for the music mainly. But it shows how poorly-initiated the power priority for the LCD backlight is, and thus I think it would be really nice for both our eyes and the battery life if there was an option to dim to backlight to our choosing.

TIA.

PS: Other targets, if not all, may benifit from backlight dimming as well.
This task depends upon

Here's the brightness patch for iPod Video
http://www.rockbox.org/tracker/task/5234

Some custom build firmwares in the forum have it included.


Regarding Power:
Usually (using the iPod as music player) the backlight is only enabled for short periods. So the battery savings by dimming the backlight are small. When the backlight is statically on (eg. in a car), the player is mostly powered externally.
The main reason why I made the patch is to not get everybodys attention when browsing music in a darker room (eg. a plane at night). With full brightness, the iPod can be used as flashlight (which also can be quite useful sometimes).
