turn the backlight down, run a few registry hacks for the battery. Thats what I've done and I can go on one charge for 2 days of light use, 1 day for heavy use.

The most important part is to get a good first (and for me, second) charge on a battery. I drain it to 0, charge full, drain to 0, charge full, and then use it naturally at that point, charging if I go below 30%.
