how to decrease usage for increased battery life?
enz660:
what should I change my settings to so that I get the most battery life possible. I have already made it so the backlight stayes on for a minimal time, is there anything else? thanks.

almost every rockbox setting affects the battery life to some degree, look over the rockbox manual, there might be something about your question there

Not knowing what player you have, enz660, it is hard to say what would be the most effective method of prolonging runtime.
The Gigabeat F and X models don't have frequency scaling, so disabling audio features won't save any battery.
The coldfire targets (iRiver H3xx / H1xx, iAudio X5/M5) are more optimized (as I understand it) than the PortaPlayer targets (iPods, iRiver H10), and you can probably get away with some audio effects before seeing runtime decrease.
The PortaPlayer targets boost easily, and so it doesn't take much in the way of effects to decrease runtime.
Archos - I can't speak for them.
Something which will make a dramatic difference on all targets, though, is hard drive usage.
If you select an album, spin the hard drive to fill the buffer, then five minutes later change your mind, select a new album or add songs next in your playlist, you have wasted most of that first hard drive spin and incurred considerable battery costs.
Skipping tracks will also waste buffer that was (relatively) expensive to fill.

Although I'm not sure of the exact benefit, you could use an unsupported build that has the LCD brightness patch applied to it. Try using the hardware equalizer instead of the software equalizer.
Aside from that there's not much else you can do to save your battery other than following Soap's instructions about Hard disk spinning and buffer usage.
