Improved battery life with 10.5.2?

[CyberBob859]

Ever since I upgraded my MacBook to Leopard, and specifically to 10.5.2, I'm noticing that I'm getting much better battery life on this machine versus when it ran Tiger.

This is a 1.83 GHz Core Duo MacBook, 2 GB of RAM, with a WD 120 GB hard drive.

Previously, with Tiger and I how I typically use the computer, I would normally get around 2 hours to 2 hours, 15 minutes of life before getting a "You are now running on reserved power" warning message.

Now, I'm routinely getting close to 2.5 hours of battery life. And today, it pushed 2 hours 35 minutes.

I normally use my machine at three-quarters brightness and have the setting for "better energy savings" on battery power. I do "office-type" work, and surf the web. Sometimes I have music on in the background, other times not.

Has anybody else noticed this with Leopard and 10.5.2? Needless to say, I'm happy with this result.

I am getting around 15 minutes more with my 2.16 17" CD MBP. That's not a whole lot, but it makes a difference in being able to use my MBP for an entire class on battery instead of getting cut off 15 minutes before the end.

You know, I thought I'd imagined this, but now I'm not so sure - I seem to be now getting close to four hours life with my Mac Book Pro, as opposed to approx three an a half - I didn't consider the recent upgrade to 10.5.2 until now, but it does seem I'm getting a little more out of the battery?
