new macbook pro horrible battery life! 94% capacity after 55 cycles?

[mbpnewbie]

I still have 100% health after 13 cycles.... Maybe mines abnormal

Im on 67% at 196 cycles, but i've got 6% Battery remaining.

When its on 100%, i usually have around 90%

With my unibody MBP (2.4GHz), the battery health indicator is basically useless. It fluctuates between 94% and 100%: I cannot realize what it depends on. Now it is at 99% after 19 cycles, some days ago it was at 94%. I calibrated the battery twice with no particular effect on that weird behaviour.

With previous-gen, Penryn MBP the indicator was much more stable. It was slowly going down...

2 gen ago mbp - first battery died in a year, 2nd battery is at 85% with 35 cycles. I'm thinking these batteries aren't that great, but they're all like that. My friend has a year old PC laptop thats capacity is probbly around 70%..unfortunately there doesn't seem to be a health indicator like macs have for pcs.

my battery changes from 94% to 100% depending on its mood at the moment it is on 100% on 42 cycles. i tend to run the laptop on battery of a while and then connect to the power. i have never really timed how long it lasts.

Calibrate your battery?

You think you have it bad?!?!?

Last calibration: last friday, 09/01/2009
Next calibration attempt: some day this week...

Almoust forgot... it says it's at 95% total capacity but iStat Pro says it's status is "Charged" and that's confirmed by System Profiler also with a "Charged" status.
