Q: 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?

MacBook Pro, Mac OS X (10.7), 2.4 GHz Intel Core 2 Duo, 4 GB Ram

Same for me. It's been doing it since the inital install. Everyone keep posting if you have this issue so Apple can see and set up a fix!

Which 2.4 C2D MacBook Pro do you have? There are about 5 different MBP's with that processor.

Update: per Apple Care, I reset the SMC earlier today. I'll see what the battery life is like tomorrow, and if that doesn't resolve the issue, I'll be re-installing Lion.

Ha!

Microsoft is working hard to improve efficiency of his operating system and Apple gives away its reputation as a provider of an economical operating system. Inverted world in these days!

An efficient and energy-saving operating system must have the highest priority at this time! Microsoft has recognized that!

I'm having the same issue. I have a 2011 MacBook Pro 15 2.0 i7 4gb ram. 500 gb hd. Previously I could get between 7-8 hours. After installing Lion, it is maybe 4-5. Any ideas?

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.
