I had my battery replaced yesterday on my MBP 13", running 10.6.8, from mid 2010. I charged it to 100% last night and worked with the AC adapter for a while. iStat Pro said my health was at 100%. I then turned off my computer for the night, and this morning, with 0 cycle count still, my battery health is at only 99%. Today I'm doing a calibration of my battery, but I'm concerned that it's already gone down 1%. I know 1% isn't a big deal, but shouldn't it have stayed at 100 for more than a few hours, which is really all it's gotten since I had it turned off?


Here's the current stats of the battery

    You're fine.  As stedman1 says, it changes all the time.


    My battery goes from 5720 one day to 5610 to 5724 and now to 5684.


    If your battery lasts you over 5 or 6 hours in normal use - not using games, then you have nothing to worry about.

    are you getting over 5 hours of use from it?


    if so, try not to worry about it so much...........


    like i said before, my battery keeps on changing i'm at 5507.  last night i was at 5601.


    if however, you feel that it's not performing as it should, then take it to Apple and have them test it for you before your warranty expires.....


    good luck..
