Lion - Horrible MacBook Pro Battery Life

After upgrading to Lion, my MacBook Pro battery life has been severly affected. After 1.5 hours of light web browsing, my battery has decreased to 40% from 100% after charging all night.


Notes: Spotlight completed indexing the hard drive over night, and the laptop remained plugged in charging. The fans seem to be running normally, not at a higher rate. The backlight is at 50% brightness.


Thoughts?

Ars Technica reviews OSX Lion and makes the following observation:


'When an application is terminated in Lion, all the usual things appear to happen:

The small dot will disappear from beneath the application's Dock icon.

The application will no longer appear in the command-tab application switcher, or in Mission Control.

You therefore conclude that this application's process has terminated.

A quick trip to the Activity Monitor application or the "

ps
" command-line utility may dissuade you of that notion. Lion reserves the right to keep an application's process around just in case the user decides to relaunch it. Upon relaunch, the application appears to start up instantly—because it was never actually terminated, but was simply removed from all parts of the GUI normally occupied by running applications.'

Running these extra processes might explain the poorer battery life some MacBook users are reporting.
