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?
