Can anyone tell me if they have seen this glitch before... I charge my 4 month old ibook G4 1 Ghz to 100% then I use it (on battery) for most of the day at work. When I get home I rechage it until the menu bar indicator shows charged. Now if I check the percentage it only show 99.7%, then if I let this go (and don't reset the power manager) after the next couple of charges it show 97 to 97% (the time remaining is about 4.55 hours). Now if I reset the power manager it fixes the issue but this has been like this since day 1. My ibook has the following specs>
G4 1 Ghx Processor 768MB Ram 40GB HD No airport or blue tooth options OS X 10.4.2 (started out on 10.3.3 and was soon upgraded to 10.3.9 then to 10.4).
Thanks for nay info.

Don't mess with it. And don't fret. It's supposed to do that.
I have some questions for you:
How low does it go (typically) when you "use it (on battery) for most of the day at work"? Have you done this for 4 months daily? I.E. about 100 times?
Have you ever calibrated your battery?
Bonus question -- in terminal -- what does
/usr/sbin/ioreg -p IODeviceTree -n battery -w0 | grep Bat
return?

I go to work at 8:30 and by 1:00 or so it goes into low battery sleep. I then plug it up and let it charge until 5 or 5:15 (it usually has a full charge by then). I can get about 4.50 to 4.75 hours off of one charge although I lost some time when I upgraded to Tiger (and from what I see on Apple's forums I'm not alone).

probably but I don't use it constantly every day sometimes I am on the road and it is asleep for most of the roadtrip.
Have you ever calibrated your battery?
Yes several times trying to fix this, I have also reset the power manage and zapped the PRAM.
Bonus question -- in terminal -- what does /usr/sbin/ioreg -p IODeviceTree -n battery -w0 | grep Bat
cool command. I had never seen this one before - thanks.
Right now I am 86% (haven't charged it yet). but here are the results: "IOBatteryInfo" = ({"Capacity"=3945,"Amperage"=18446744073709550726,"Cycle Count"=47,"Current"=3415,"Voltage"=15999,"Flags"=4,"AbsoluteMaxCapacity"=4400}) MikeRs-Computer:/

this is still running off of the battery, I will charge and run this again and see what I come up with.
PS: I figured that it was not much of an issues but I am anal about my computers and now all of the PC people are saying that it is something wrong in the OS.
