How Much Electricity Does an Apple iBook G4 Use?

I still use an old Apple iBook G4, it's so old and well used several keys are missing. But just how much energy does it use? I tested in various modes with as few applications in use as possible and the battery removed;

Normal: 21 - 28W
Better Performance: 23 - 30W
Energy Saving Mode: 21 - 27W

Screen Brightness at Lowest: 18 - 23W

Device Attached (iPhone): 8 - 12W (additional)
Device Attached (full battery): 4W (additional)

Energy Saving Ideas for your Apple iBook G4
  • Use the settings for "best battery life" from the menu bar
  • Turn off Bluetooth and Wifi when not required
  • Close programs not in use
  • Shut down rather than allow the computer to snooze

For information on the electricity consumption of other products check out "How Much Electricity Does a ... Use?"

Please Note the energy use figures are taken from an energy monitor and are not scientifically analysed, therefore the range and margin of error is greater. If you would like a specific product tested let us know and we will endeavour to check it out.
