Terrible battery life?

[sparkerc]

At the moment, I have been on battery for 17 hours and I have 33% to go. For a while I was having terrible battery life until I found that Firefox was chewing up the CPU. I found this holding down the home screen button and then hitting task manager to see what processes were active. Stopped using FF and went back to the default browser and you can see the results above. I am running stock with all of the bells and whistles turned on (i.e. GPS, bluetooth, screen at 80%, etc)
