Increasing Battery Life

(1/2) > >>

Hi,

I've just downloaded and installed Rockbox onto my iPod Mini 2G and I am impressed. One thing I would like though is increased battery life... Is it possible in the config or anything to turn off the screen when hold is on? As when hold is on the iPod is usually in my pocket so there is no need for the screen to be on so i may as well save the battery... Are there any other battery saving config options I can use to keep battery life to be as good as possible?

Thanks

You can turn off the backlight while hold is on, though I'm fairly sure that's the default.

I've found that turning off the screen with hold (Not easy to do, I coded my own theme to do it on the While Playing Screen) only saves you about 15 minutes every 6 hours or so.  I've also found that the two biggest eaters of battery are Hard Drive spinup and backlight being on.  So, minimize those (by essentially starting your playlist and then never touching your ipod until you want to stop it) and you'll maximize battery.

"Maximum" battery may not be long enough for you, of course.  I said "15 minutes every 6 hours" because turning off the screen made my iPod last 6h15m instead of 6h00m  :)

thanks,  I might install the theme, although I couldn't find it in the list of themes, would you mind sending me a copy? 1 Other thing, surely if it's just a theme all it does is tell Rockbox not to output anything, thats not the same as turning the screen off completely is it?

Thank

Monochrome and greyscale displays use very little power. As Yotto said the backlight is the killer.
Some other ways to get longer battery time is to use efficient codecs, and no higher bitrate than neccesary, I'm not sure which codec is fastest on ipods but i think mp3 is faster than vorbis which is in turn faster than aac...
Also disable dirchache if you do not browse files a lot and disable "load to ram" tor the database if you do not browse it a lot.

And make sure that you arent using the equilizer either.
