I use it on airplanes and in airports and have gone over three hours, and have yet to have the battery run down on me. Of course I turn off all peripherals that I am not using to conserve battery life. In the BIOS you can turn off the USB ports, Ethernet LAN, Audio, Wireless LAN, Webcam, Speaker, and Card Reader. I keep a 16GB SD card in the cardreader at all times and use the USB to back up my data, but the other peripherals are turned off. And, of course, I could get an airline power adapter and an auto power adapter. Some of the Overseas/Surf models are reported to have a
4400mAh battery, while mine has a 5200mAh that is the same physical size. There is a 10400mAh battery (Quite a bit larger; see
formatting link
for a picture) that I see advertised on eBay, or you can always keep a second charged battery in your laptop bag. Given the potential for fires, I personally only use OEM batteries. so I am waiting until Asus starts shipping the 7800mAh OEM battery (See
formatting link
). Another possibility that I haven't looked into is to underclock the Eee further than Asus is already underclocking it. I have seen info on overclocking a Eee, but haven't paid much attention. If anyone here has underclocked one, please share the details.
