It's the same with most laptops or umpc's.
On the eeePC, wifi has a very noticeable hit on power consumption.

Although disabling other hardware might make some difference, wifi or 
bluetooth are the worst. Maybe backlights are second, turn it down to 
minimum required or have it auto shut off quick..
