1350mAh battery support for iPod Photo
Packgrog:
I installed the following battery into a 30GB iPod Photo over the weekend:
http://eshop.macsales.com/item/Newer%20Technology/BIPOD1350MPH/
I charged it for 8 hours before installing Rockbox. I went through the list of battery options, and the options maxed out at 1200mAh. Is that an adequate setting for a 1350 mAh battery for accurate charge level display, or should more options be added? Does it make a difference to how Rockbox handles power management, or is it only important for displaying the charge level?
Out of curiosity, is battery life under Rockbox still lower than it was under the regular iPod software? I've only used Rockbox on the iRiver H120 up to this point, but wanted to try it out on an iPod my mom no longer wanted to use. I'm loving it, no question, but am uncertain of the battery life, and if there's anything I can do to improve it.

It doesn't make any difference for power management. It actually also doesn't make any difference for the shown charge level, only for the remaining runtime estimate.

As far as I know we should be about equal or better on all iPods these days. My iPod Video (with my settings) lasts for ~4 hours longer in Rockbox than in the OF :)

See http://download.rockbox.org/daily/manual/rockbox-ipodvideo/rockbox-buildch8.html#x11-1430008.4 and turn on "Sleep (after backlight off)", so that it will turn the LCD screen off entirely when it's not being used, instead of just the backlight.
That's the only setting that makes a really big difference to battery life, if you use cheap codecs like MP3. If you use an expensive codec, turning off DSP effects (like the equaliser, crossfeed, etc) will help too, but there's plenty of CPU time free to do these effects with MP3s.
