    At 157 cycles, my Macbook Pro battery is already at 85%... is something wrong?
    It usually hangs somewhere around 96-99, but the other day it dropped down to the 92-ish range. I calibrated the battery last night, and when it charged back up, it was at 85%.

    Is something wrong with it? I purchased it in November of 2009.

    I had an apple genius tell me once that they cover it up to 300 cycles. I dunno if this is true but it might be worth a shot. If it is incorrect you are no worse off than you are now.

    I heard it was 1000 cycles?

    If you have less then 1000 cycles and you are at or below 80% health they will replace your battery.

    Its under 300 cycles or 1 year (whichever comes first) drops to 80% or below and they replace it. Wouldn't hurt to go ahead and get an appointment and see what happens. You're almost there and only halfway on cycles. Here's the link I found this on Apple’s MacBook Battery Warranty Standards, Clarified | TechNews.biz

    By the way, I also noticed the same issue after I calibrated mine. Battery was great until I did that. It seemed to drop considerably. I was at 90% on only 50 or so cycles after my second calibration. I've been using since and not calibrating and I'm noticing that I've actually jumped up to 93% now at 65 cycles. Could just be a coincidence but I'm keeping my eye on it just it case I need a replacement as well.
