So what do you have in /sys/class/power_supply/battery/current_now
when idle and not charging ?
Here is for instance a simple script that will log interresting values
every 30 seconds :
#!/bin/sh
log="$HOME/power.log"
while true ; do
(
date +"%Y-%m-%d_%H:%M:%S"
cut -d' ' -f 4,7 /proc/apm
cat /sys/class/power_supply/battery/charge_now
/sys/class/power_supply/battery/current_now
/sys/class/power_supply/battery/voltage_now
) | xargs echo
sleep 30
done >> $log
I would be very interresting in comparing various people results.
