Re: Fedora 14 and Battery Life?
The thing about battery life to keep in mind that it degrades over time. I dual boot windows 7 and my battery last maybe 2 hours at most after just 6 months, when i originally purchased it, it was rated for 7 hours. To get more hours out of laptops you'll need to sacrifice quite a bit. Run a dimmer screen, sleep after just minutes, don't use a screen saver, don't use peripherals like a USB Keyboard or mouse, cut the desktop effects, etc...
I don't see a difference between the battery life on Windows 7 and F14. I'm running the KDE version and it's pretty good at making adjustments to save the battery. Linux and KDE generally will cut more processes that windows 7 to save the battery. Like disabling the transparency and stop indexing files. But like I said, there's not really a difference in how long they'll last.
I can say that Linux still hasn't nailed the estimated battery life. I unplugged my laptop right before I started writing this post, and in 3 minutes i went from 99% to 93%. But last night it went from 15% to 10% after a full hour of use.
