Okay, I have been experimenting and I enabled smartreflex yesterday and this time Nokia N900 just lost about 1% battery idling with WiFi through the night (8-pm to 7 am), about 11 hours. Even more amazing! Not sure how it will affect my use time, but standby is wow! Here's what I did in the shell: root echo 1 > /sys/power/sr_vdd1_autocomp echo 1 > /sys/power/sr_vdd2_autocomp PS: See the break in the batteryeye graph, strange aye? That's when I enabled smartreflex :-)
