Review of the Asus Eee battery

Recently I wrote an Asus Eee review, but at the time I had just gotten the netbook and hadn't had a chance to test out the battery. Now that I've been using the Eee for a couple of weeks, I finally feel ready to post a review of its battery.

First of all, my Asus Eee came with the 4400mAh battery. Despite its small size, I've been sufficiently impressed with its performance. With normal use (for me — which means Outlook is open, wireless is on, screen brightness is up, and several Internet windows and/or Word windows are open) I get about three hours of battery life. However, one night I got about two hours on half a battery with the wireless turned off, screen brightness turned down, Outlook and Internet windows closed, and the processor speed turned down to the slowest (power-saving) mode. I haven't been able to go four hours yet without using email or Internet, but I imagine I'll get about four hours of battery life with all of the power saving settings on!

I find this all very impressive. I'm also considering buying the 6600mAh battery for my Asus Eee, simply for the sake of having an extra hour or two of battery time, but it doesn't seem to be a necessity!
