As my pandora spends most of it's time idle waiting for me to do some occasional hacking (something becoming more and more rare), I've decided to do a few hacks on background processes to reduce their activity. The other rather obvious thing to reduce idle power usage was to dim the power LED (which turned out quite significant, no idea why it wasn't done before, you can edit /etc/pandora/conf/led.conf to customize). If LED is ignored. the improvement is a bit hard to detect with the fuel gauge (battery monitoring) chip, as reading the chip itself requires waking up the CPU (obviously) and OMAP peripheral power domain to activate i2c. Still I think it's quite visible. Run "Upgrade Pandora OS" to get this stuff. As usual chances are that something got broken so testing is welcome.
