MacBook / MBP Battery Times with Leopard?
Anyone else notice a hit? My current batter is less than 90 days old, so it can't be my imagination. I've seen a few others belly-aching too..
Theories:
- Core Animation is asking more of the video card?
- Sleep problems?
- Crappier power management?
- Increased memory usage is the culprit?
- Apple is stealing power over teh internets!

Didn't you hear?
Time Machine has a secondary feature, sending your unneeded extra electricity into the future, where a post-global warming world struggles to generate enough power to satisfy the consumption levels of "The Machine" (known to us as America) after all the fossil fuels have run out. Apple is the only thing standing between future-us and extinction! You wouldn't dare doubt the power of Apple, would you?!
(Sorry, I'm in an odd mood)

10.5.1
I just installed 10.5.1, not sure what they did, but it improved my battery life by about half an hour. Here are my stats (roughly)
10.4 - Average Battery Life 4 hours 45 min
10.5.0 - Average Battery Life 4 hours
10.5.1 - Expected Battery Life 4 hours 37 min

looks about the same here,
looks about the same here, at least in terms of the estimated life; i will test out the actual drain in class tonight, but seems like 10.5.1 is an improvement
my estimated battery life
my estimated battery life has definitely taken a hit (down to 2-3 hours, from 3-4 hours, or thereabouts), i'm not sure if the actual life has suffered or not, but i believe it has. i haven't taken the time to do a full battery calibration since installing leopard yet, but it could very well give you a more accurate, if not more favorable reading
see here for directions:

-sleep has been ok for me, although i had to move my external mouse for a hub to a native port to have it work after wake up
-power management has been a bit wonky (in certain situations, my internal display seems not to obey preferences set for 'automatically reduce brightness before display sleep' and the actual time period before display sleep)
Mine seems fine, I might've
Mine seems fine, I might've taken 30 minutes off battery life, but when I go into power save battery mode (bluetooth power off, and airport power off), I'm still getting over 4 hours and my battery is at 96% capacity. If I leave bluetooth and the airport on, then I notice a larger hit in battery life, but that happened in Tiger as well.

now that you mention it,
now that you mention it, i've been using wifi on campus more, so some battery life is accounted for there
sounds like 10.5.1 isn't too far off, it'll be interesting to see what gets fixed (or broken)
Funny you posted this...
Funny you posted this... just today I noticed that my machine after 1.5 hours of use had 35-40% left while Julia's MacBook running 10.4 had 60%. I was running parallels though so that probably nuked my battery, but perhaps I'll try and compare between the two before her's gets upgraded.
Overall, I've found things to be just as stable as Tiger. I've had a few kernel panics related to Samba, but nothing too bad.
