    It doesn't matter. Use it how you want to.

    It's normal.

    96% Battery health , 12 loadcycles in just 1month since it was purchased.
    Do i have a defective battery in that case?

    Because i read some forums that at 300 loadcycles there battery health is at 80% while mine is only at 12cycles

    Read the FAQ I linked to. You are not to first to ask these questions, and you will not be the last, thus this FAQ I linked to can help answer most of your battery related questions.

    In short, health fluctuates, constant power adapter usage is not advised, battery time depends on CPU usage. /arse

    96% peak after only 12 cycles seems pretty low to me. According to Apple, "The built-in battery in the new 13-, 15-, and 17-inch MacBook Pro is designed to retain up to 80% of its original capacity at up to 1000 full charge and discharge cycles. "

    I usually work with the MBP on the power adapter but I do allow it to discharge nearly completely every few days.

    Thanks alot

    Again guys, thank you for sharing me your thoughts regarding this issues,. I appreciated it most..

    From time to time i may be needing your help again since im totally new to mac.
    Luckily your all here. Thanks to macrumors.

    ----------

    True, but it happened one time that my battery health drops to 98% at 10 loadcycles then couple of days went back to 100% battery health.
    Then just this morning it was at 96% battery health at 12 loadcycles. Hopefully it will return back to 100%.

    There is NOTHING wrong with using it plugged into the adapter at all times.

    I know someone at uni who has had his plugged in for the most part of the last 3 years, and he's still on 86% health and gets 5-6 hours battery.

    Battery Health and Load Cycles????

    [​IMG]

    As shown above, anyone can advise me whether this datas is reliable because what Apple is claiming for new macbook pro 2012 is that At 1,000 cycles the battery is suppose to still have about 80% of its original full charge capacity

    im with MBP 13" i7 (mid 2012), none heavy apps user just a basic web browsing so far.

    13 Load Cycles at 95% Battery health VS. 1000 LC at 80% Battery Health.

    i think im way too low and my battery is fast degrading..

    Any advise?

    It's nothing more than common reporting error. Wait until you actually have a problem instead of extrapolating your results. You also already asked about this here.

    Apple will be the only ones to tell you if there is an issue as they use their own hardware test and do not rely on third party apps.

    I took my MBP into Apple about a week or so ago. It was 2 weeks old, with only 2 cycles on it, and battery at 92%.
    People on this forum told me it was normal and I was OK etc, but I felt something was wrong.

    The Apple rep told they do not bother looking at third party apps as they are inaccurate. She ran their own disgnostics via an ethernet which reported that there was actually an issue. She asked if I wanted a replacement laptop or a new battery. I just opted for the latter as I was happy with the laptop otherwise.

    New battery, now has 4 or 5 cycles I think, and is at about 98%
    I havent calibrated this battery, I just use the notebook from battery power and charge when its around the 30% mark. Seems to be doing much better this time round!
