You must have done something wrong. I frequently test power comsumption and I get 54 mA on a fully charged battery, dropping slowly as the battery discharges[1] and nearly 20 hours battery life. FWIW, I test with this command on a Debian installation: sleep 120 && cat /sys/class/power_supply/battery/{status,current_now,voltage_now,capacity} [1] It's supposed to be the other way around - current increasing as the battery discharges - but there's a current leak somewhere. It was down to 46 mA not too long ago with a kernel from the andy-tracking branch. -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
