after the past post on battery capacity, I decided the check again after all the repairs ive had.

im annoyed to see my bat life down by about 30min and the capacity seems to reflect this. Went from 4400 area down to 4100 now.

My battery's capacity kept on going steadily down from the time I got it replaced from Apple from 4500 to 43, 42, eventually up to 40. Yesterday it went up to 4450. I don't know what is going on but battery time seems to be about the same.

mine depends on how i use it while using battery power. if i run it down on low cpu, low screen brightness, no bt, no ap, etc, the capactiy creeps up slowly. but if i put it up on high performance and run the battery down, the capacity drops. she's labile.

the capacity of my battery goes down, too. it was 3400 ah. some days later ist only 3100ah. the powerbook runs only 1 hour while internet browsing and writing. playing games shortens it battery-life daramtically down to 20 mins.

apple sent me a new battery. but it was broken...

Last night i put my powerbook to sleep at about 40% battery life. The capacity was at 3.432Ah.

I woke up this morning and when i woke up my Powerbook the battery life was at 8% and the capacity is down to 3.176Ah.

I'm going to do the calibration trick tonight and see how it goes.
