A recent Bios update disabled a Bios option that let you choose between performance and battery life so that the CPU would flick between 900MHz and 630MHz respectively when on battery power. But the update seems like a bit of a red herring since it didn't improve battery life substantially on my Eee PC (a different one to the one we reviewed). A bigger issue is the quality of the battery being used, since each Eee battery appears to behave different and every one I've seen isn't calibrated properly. With the battery fully charged, my Eee PC 900 reports 80 per cent battery life remaining as soon as it is unplugged. It then drains down to 7 per cent over the course of one hour, where it stays for a second hour before dying.
