• On Linux, get instant battery power consumption with (unplug power cord first!):

watch grep rate /proc/acpi/battery/BAT*/state

• Lucid
  • Luminosity set to lightest
  • Text console (X at login console, no X activity)
  • Wireless off
  • Lowest average we get on idle is 1185mA on BAT0 (oscillation between 1170 and 1200).
  • When screen goes off, we have 965mA, and after wake-up we get 1115mA.
