Post your battery life with Mac OS X!

OK, here's the procedure:

- Nothing at all connected to the machine (no ethernet cable, no external drive, no nothing)
- Set System Preferences>Energy Saving to "Never" on both settings.
- Set System Preferences>Desktop & Screensaver to "Never". This ensured that the screen would always stay on.
- Switched off the machine, waited until battery was fully loaded (green light)
- Unplugged the charger, switched on the machine at 16:07 pm.
- While booting, set the screen to half brightness (5 steps out of 10).
- Let it sit there, doing nothing. Not very typical of real usage, I know, but I wanted to know what the maximum battery life would be, and it ensures that the procedure can be used by others in a "scientific" way
- Gave me a battery-low warning at 10% left or so (IIRC)
- Shut down by itself at 18:39pm (0% battery).

==> 2 hours and 32 minutes of battery life under Mac OS X (iATKOS 4i release).

Please note:
- I replaced the SSD in my One with a 30GB 1.8" drive.
- SpeedStep was enabled, so the One ran @ 800 MHz most of the time.

 

thanks for the info. i have not been able to leave mine alone long enough to test this

 

i would love to post my battery life but i have no idea how to fix it. i have the kalyway 10.5.2 disk installed then upgraded to 10.5.3, then 10.5.4 and still my batter icon isnt showing me any status. i know there must be another post where it could explain it more in deph but they dont seem to work for me. i also installed "ACPIBattery.kext" from paul's utility bundle, repaired, and reboot but still no luck :roll:

 

2:22 OSX iATKOS 4i with updates from apple

 

about the same for me running same setup.

i am leaning more towards this for $69 which can charge/run other devices rather than the $120 or so 6 Cell battery for the Aspire.

 

Mine only runs for about 2:00 when doing nothing and under heavy usage 1:30 I wonder whether my battery is getting old already (44 charge cycles it says under osx). My speedstep works and I'm always using the lowest backlight setting.

 

I average roughly more than 5 hours with my 6 cell

 

Are you running retail leopard? and if not, what distro do you run?

 

Mine's about 5 - 5.5 hours with my 6 cell iAtkos v4i.

 

I got only 4:24 out of my 6-cell...
10.5.5
SuperHAI's speedstep
Voodoo 2c

I'm going to test again

 

Sorry, I'm running iAtkos v4.1 with speedstep, (OS X 10.5.4)
